     DETAILED DESCRIPTION 
     In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein. 
     Various persons, including, but not limited to, physicians, nurses, healthcare professionals, healthcare providers, healthcare administrative staffs, and hospital administrators can operate or make use of illustrative embodiments of the 3D avatar medical information system disclosed herein. For brevity these users are referred to as “healthcare professionals” hereinafter. Healthcare professionals can be users of the 3D avatar medical information system. Patients can also be users of the 3D avatar medical information system. 
     Embodiments of the invention relate to systems and methods for presenting a healthcare professional with a three-dimensional representation of a patient, referred to as a “3D avatar”. The 3D avatar can be viewed when the healthcare professional wears a special headset, visor, glasses, eyewear, or looks at a specially produced display, configured to display three dimensional images. The 3D avatar represents a human body in three dimensions. The 3D avatar can be used to link medical information of the patient to a specific site on the patient. For example, a patient recovering from left knee surgery may visit a physician. The physician may put on a holographic eyewear configured as described below to produce a 3D avatar image representing the patient&#39;s medical record. The physician will see a graphical indicium of a file associated with the left knee position on the avatar. The eyewear system will be able to record the position of the physician&#39;s fingers. The eyewear system can determine if the physician has touched the graphical indicium of the file image associated with the left knee. If the eyewear system determines that the physician has selected the file associated with the left knee, it may display surgery records, such as x-rays, notes, surgery details, and other information associated with the patient&#39;s left knee. This allows the system to conveniently and intuitively store medical information for a particular patient in a manner that is easy for the physician to access and understand. 
     It should be realized that two-dimensional “2D” and three-dimensional “3D” avatars are non-limiting examples of the one or more interactive images for managing patient healthcare. In some embodiments, the systems and methods disclosed herein make use of a 3D avatar for capturing patient medical information and for medical record keeping. The 3D avatar can be a holographic 3D avatar. Non-limiting examples of technologies for implementing the methods and systems disclosed herein include mixed reality technology, augmented reality technology, and virtual reality technology. 
     System Architecture 
       FIG. 1  is a schematic illustration showing exemplary interactions between a healthcare professional  100  and medical information using a 3D avatar  102  implemented by a 3D avatar medical information system (3D AMIS)  104 . The healthcare professional  100  can interact with the 3D avatar medical information system  104  using a holographic eyewear  106  that is configured to display 3D representations of the avatar or other information. Microsoft® HoloLens® is a non-limiting example of one type of holographic eyewear that may be used within embodiments of the invention. Other non-limiting examples of the holographic eyewear include Google Glass®, Oculus Rift®, Sony® Glasstron™, and HTC Vive®. 
     The holographic eyewear  106  generally includes two lenses, one for each of the healthcare professional&#39;s eyes in order to present a 3D image within the healthcare professional&#39;s field of view. The holographic eyewear  106  can display information, for example medical information, to the healthcare professional  100  via the two lenses. In some embodiments, the holographic eyewear  106  can communicate with to the healthcare professional  100  using one or more audio devices (e.g., speakers and earphones), in wired or wireless communication with the holographic eyewear  106 . 
     The holographic eyewear  106 , using one or more sensors in wired or wireless communication with the holographic eyewear  106 , is configured to monitor and determine the healthcare professional&#39;s commands or instructions. The healthcare professional  100  can give commands to the holographic eyewear  106  using his gesture. Additionally or alternatively, the healthcare professional  100  can give commands to the holographic eyewear  106  using the movements of his fingers, hands, arms, or legs (or any body part) or other objects connected with the healthcare professional  100 . 
     The holographic eyewear  106  can be in wired or wireless communication with the 3D avatar medical information system  104  through a network  108 . The 3D avatar medical information system  104  can be configured to retrieve medical information, for example medical records, from an electronic medical record system (EMRS)  110  for display by the holographic eyewear  106  to the healthcare professional  100 . The medical information retrieved from the electronic medical record system  110  can be captured and recorded by two or more pairs of the holographic eyewear  106  and/or two or more of the 3D avatar medical information systems  104 . In some embodiments, the medical information retrieved from the electronic medical record system  110  can be captured and recorded by systems other than the holographic eyewear  106  and the 3D avatar medical information system  104 . Non-limiting examples of the medical information captured and recorded by such systems include medical instruments not part of the 3D avatar medical information system  104 , for example MRI machines, X-ray machines, and blood analysis instruments. 
     In some embodiments, two or more healthcare professionals and patients can simultaneously interact with the 3D avatar medical information system  104  using two or more pairs of the holographic eyewear  106 . The two or more healthcare professionals  100  may be in close proximity or far from one another, and the system may link them to one another though the network  108 . 
     3D Avatar 
     In one embodiment, a 3D avatar  102  can be displayed with medical information of a patient. The medical information of the patient can be displayed as appearing on top of or behind the 3D avatar  102 . The medical information of the patient can be displayed as overlapping or adjacent the 3D avatar  102 . The medical information displayed can include some or all of the patient&#39;s medical information stored in the electronic medical record system  110 . The medical information displayed can be captured and recorded during the patient&#39;s current or previous doctor or hospital visits. The medical information displayed can be related to a disease, an instance of a disease, a group of related diseases, or a medical specialty. 
     Medical Records 
     The medical information can include medical records  111 . The holographic eyewear  106 , using its one or more lenses, can display the medical records  111  as the medical record content items  114 A-C to the healthcare professional  100 . The medical records  111  can be displayed together with the 3D avatar  102 . The medical records  111  displayed can be grouped together based on, for example, the disease type, disease severity, symptoms, disease progression and healing, medical specialty. The medical records  111  displayed can be grouped based on the doctors creating the medical records  111  or the hospital visits during which the medical records  111  are created.  FIG. 1  shows that the medical records  111  can be grouped into medical information categories  112  by disease types: “headache”  112 A, “rash”  112 B, and “burn”  112 C. The medical records  111  of categories  112 A,  112 B, and  112 C can be displayed as medical record content items  114 A,  114 B, and  114 C respectively. A medical record content item can include previews of the medical records  111 . 
     The holographic eyewear  106  is configured to display the recorded content items  114 A-C at different geographical locations relative the 3D avatar  102 . The 3D avatar medical information system  104  can determine the locations of the medical record content items  114 A-C by reference to data stored in the medical records. In some embodiments, the locations of the medical record content items  114 A-C are determined by healthcare professionals when creating the medical record content items  114 A-C. In some embodiments, the locations of the medical record content items  114 A-C are determined by healthcare professionals for existing medical record content items without location information determined when they are captured and first recorded. 
     The medical record content items  114 A-C can be displayed, for example, as appearing on top of the 3D avatar  102 , overlapping the 3D avatar  102 , behind the 3D avatar  102 , or adjacent the 3D avatar  102 . In some embodiments, the medical record content items  114 A-C can be displayed as appearing spatially near locations on the 3D avatar  102  that correspond to organ locations of a person, for example the 3D avatar&#39;s head, arm, leg, kidney, or liver. The healthcare professional  100  can move the medical record content items  114 A-C to different pinning locations relative to the 3D avatar  102  as desired or required to reflect, for example, patient status and disease progression and healing. For example, to move the medical record content item  114 C from the right knee to the left knee of the 3D avatar  102 , the healthcare professional  110  can “touch” a graphical indicium representing the medical record content item  114 C with one or more of his fingers, and move his one or more fingers from the right knee to the left knee of the 3D avatar  102 . The holographic eyewear  106  can include one or more image sensors for capturing such a “touch” and “movement.” 
     As illustrated in  FIG. 1 , the medical record content item  114 A of the “headache” category  112 A can be displayed as appearing spatially near the head of the 3D avatar  102 , where the patient has suffered or is suffering a headache. The medical record content item  114 B of the “rash” category  112 B can be related to a rash on the right forearm of the patient, and the medical record content item  114 B can be displayed as appearing on top of the right forearm of the 3D avatar  102 . The medical record content item  114 C of the “burn” category  112 C can be related to a burn on the right kneecap, and the medical record content item  114 C can be displayed overlapping the right kneecap of the 3D avatar  102 . 
     Non-limiting examples of the type of data that can be included within the stored medical records  111  include text data, 2D data, 3D data, audio data, video data, or any combination thereof. The medical records  111  can include real time data, for example, real time MRI data while the data is still being collected. The medical records  111  can be text data on the severity and duration of a disease or symptom; treatment history, including drug dosage, timing, and result; and a patient&#39;s family history on the disease or symptom. Text data can be notes and observations by healthcare professionals and patients. Text data can include test results and patient information. Patient information can include name, address, phone number; contact information for next of kin; primary care physician&#39;s name, address, and phone number; date of birth; eye color; glasses prescription; use of contact lenses; blood type; allergies; medications, both dosage and frequency; procedures and surgeries, both associated dates and outcomes; family medical history; diabetes conditions; pacemaker usage, history, and model; disease symptoms, for example symptoms of Alzheimer; presence of heart stents; use of pain pumps; cancer history; chemotherapy type, period, course, and history; use of hearing aids; presence of dentures; insurance information; vaccination history; childhood illnesses; colonoscopy results; or any combination thereof. 
     2D data and 3D data can include the patient&#39;s photo ID; fingerprints; eye images; biometric information; sonogram; dental X-rays; optical images of skin moles; computed tomography (“CT”); positron emission tomography (“PET”); single photon emission computed tomography (“SPECT”); ultrasound (“US”); X-ray; mammography; magnetic resonance imaging (“MRI”); diffusion tensor imaging (“DTI”); magnetic resonance angiogram (“MRA”); computerized tomographic angiography (CTA); medical optical imaging (“MOI”) such as computed optical tomography (“COT”); neutron stimulated emission computed tomography (“NSECT”); dual-energy x-ray absorptiometry (“DEXA”); digital radiography; ductography; ultrasonography; thermography; electrical impedance tomography; magnetoencephalography (“MEG”); electrocardiogram (“EKG”); electroencephalogram (“EEG”); or any combination thereof.

     Interactions between Healthcare Professional and 3D Avatar Medical Information System 
     A healthcare professional  100  can interact with the 3D avatar medical information system  104  by interacting with the 3D avatar  102  and the user menu  120 , for example, by “touching” the various content items by raising and pressing a finger on a displayed image associated with a content item. For example, to see more information of the “rash” category  112 B, the healthcare professional  100  can “touch”  170  the medical record content item  114 B of the “rash” category  112 B as it appears to be floating in space in front of the 3D avatar  102 . To see the medical records  111  of the “burn” category  112 C shown as a timeline, the healthcare professional  100  can “touch”  172  the submenu content item  150 C corresponding to the medical records  111  of the “burn” category  112 C. To create new medical records, the healthcare professional  100  can “touch”  174  the submenus content item  160 B for creating a new “audio” medical record. The ability to interact with the various content items appearing in space may be controlled by image sensors (e.g., cameras) in the headset that determines the position of the healthcare professional&#39;s fingers at they move in three-dimensional space. 
     Other non-limiting examples of the interactions between the healthcare professional  100  and the 3D avatar medical information system  104  include zoom in and zoom out on the 3D avatar  102 , rotate the 3D avatar  102 , and orient the 3D avatar  102 . When the healthcare professional  100  wants to zoom in or zoom out on the 3D avatar  102 , the healthcare professional  100  he can “touch” the 3D avatar  102  with two of his fingers and “move” these two fingers away from or closer to each other. When the holographic eyewear  106  determines that such a “touch” and “movement” have occurred, the holographic eyewear  106  can display an enlarged or smaller 3D avatar  102  to the healthcare professional  100 . 
     Touch 
     The healthcare professional  100  “touches” a content item when the healthcare professional  100  sees, through the holographic eyewear  106 , that one or more of his fingers, hands, arms, legs, or one or more objects he is connected with, come into contact with a graphical display representing the content item. The holographic eyewear  106  determines that such a contact has occurred using, for example, image sensors of the holographic eyewear  106 . When the holographic eyewear  106  determines that such a contact has occurred, the holographic eyewear  106  can update the display shown to the healthcare professional  100  based on the programmed response to the content item that the healthcare professional  100  has “touched.” 
     Interactions between Healthcare Professional and 3D Avatar 
       FIG. 2  is a schematic illustration showing exemplary interactions between a healthcare professional  100  and a medical record displayed on a 3D avatar  102 . To obtain more information of the “rash” category  112 B, the healthcare professional  100  can “touch” a displayed graphical representation or indicium of the medical record content item  114 B of the “rash” category  112 B. When the holographic eyewear  106  determines that the healthcare professional  100  has “touched”  170  the displayed graphical representation of the medical record content item  114 B of the “rash”  112 B, the holographic eyewear  106  can update the display shown to the healthcare professional  100  based on the medical record content item  114 B “touched.”  FIG. 2  illustrates the updated display shown to the healthcare professional  100  in some embodiments of the present disclosure. 
     The updated medical record content item  114 B′ can be an enlarged version of the medical record content item  114 B. In some embodiments, the updated medical record content item  114 B′ can show more detailed medical records of the “rash” category  112 B to the healthcare professional  100 . The holographic eyewear  106  can indicate that the medical record content item  114 B′ is related to the rash on the right forearm of the patient by, for example, highlighting the right forearm by a highlight box  202 B. 
     Once the holographic eyewear  106  displays the updated medical record content item  114 B′ to the healthcare professional  100 , he can interact with it. For example, the healthcare professional  100  can zoom in on the updated medical record content item  114 B′ by, for example, the movements of his fingers. When the healthcare professional  100  wants to zoom in on the updated medical record content item  114 B′, he can “touch” a displayed graphical representation of the updated medical record content item  114 B′ with two of his fingers and “move” these two fingers away from each other  204 . When the holographic eyewear  106  determines that such a “touch” and “movement” have occurred, the holographic eyewear  106  can display an updated medical record content item  114 B″. The updated medical record content items  114 B′ and  114 B″ can have the same size or different sizes. Other non-limiting examples of the interactions between the healthcare professional  100  and the 3D avatar medical information system  104  include zoom out, click and expand, and return to the user menu  120 . 
     Disease Timeline 
       FIG. 3  is a schematic illustration showing exemplary interactions between a healthcare professional  100  and a disease timeline. To see the records associated with a highlight box  202 C or the records displayed or summarized in highlight box  202 C, the healthcare professional  100  can “touch” a submenu content item of the “burn” category. The system may display a timeline  302  that includes information relating to the burn over time. The timeline  302  allows the healthcare professional  100  to monitor the patient&#39;s disease progression and recovery and to determine whether a different course of treatment is feasible or desirable. The timeline  302  can organize and display the medical records in a visual and intuitive way over time based on where on the body each medical issue was diagnosed. When the patient returns for a subsequent doctor visit or hospital visit, the healthcare professional  100  can examine the timeline  302  of medical records from previous visits. In some embodiments, the healthcare professional  100  can scroll through the timeline  302  to review the various medical records from the previous visits. 
     The updated medical record content item  114 C′ having a timeline  302  can include multiple medical record content items of various data types, for example text data, 2D data, 3D data, audio data, video data, previews, summaries, or any combination thereof. For example,  FIG. 3  shows three medical record content items  312 A- 312 C in the updated medical record content item  114 C′. The medical record content items  312 A- 312 C can be text data, audio data, and video data respectively. The medical record content items  312 A- 312 C can represent a timeline of the patient&#39;s disease progression and recovery at different time points. For example, the text data of the medical record content item  312 A can be written notes and observations by the healthcare professional  100  regarding the burn at a first time point, for example July  23 . The audio data of the medical record content item  312 B can be audio notes and observations by the healthcare professional  100  regarding the burn at a second time point subsequent to the first time point, for example August  24 . The video medical record, displayed as the medical record content item  312 C, can include video data of the burn at a third time point subsequent to the first and second time points, for example September 15. 
     The holographic eyewear  106  can show that the medical record content item  114 C′ is related to the burn on the right kneecap by, for example, highlighting the right kneecap with the highlight box  202 C. Once the holographic eyewear  106  displays the updated medical record content item  114 C′ to the healthcare professional  100 , he can interact with it. For example, the healthcare professional  100  can look at medical record content items prior to the first time point of the medical record content item  302  shown by, for example, scrolling  310  with the movements of his fingers. When the healthcare professional  100  wants to scroll  310 , he can “touch” a graphical indicium of the updated medical record content item  114 C′ with one of his fingers and “move” the finger to the left, for example, corresponding to a time point prior to the first time point of the medical record content item  312 A. Image sensors on the eyewear  106  can monitor and capture that movement of the finger to determine that the healthcare professional  100  wishes to review records other than the displayed records. Once the holographic eyewear  106  determines that such a “touch” and “movement” have occurred, the holographic eyewear  106  can display an updated medical record content item  114 C″. 
     In some embodiments, the healthcare professional  100  can watch the video medical record of the medical record content item  312 C by, for example, the movements of his fingers. When the healthcare professional  100  wants to watch the video medical record of the medical record content item  312 C, he can “touch”  320  the medical record content item  312  with one of his fingers. Once the holographic eyewear  106  determines that such a “touch” has occurred, the holographic eyewear  106  can display the video medical record of the medical record content item  312 C. Other non-limiting examples of the interactions between the healthcare professional  100  and the updated medical record content item  114 C′ include zoom in, zoom out, click and expand, and return to the user menu  120 . 
     Patient Timeline 
     In some embodiments, the holographic eyewear  106  can display a timeline of a patient to the healthcare professional  100 . The timeline can display time points at which medical records are available for the patient. The healthcare professional  100  can scroll through the timeline to review the patient&#39;s medical records at different times. As the healthcare professional  100  scrolls through the timeline, the display of the medical records can change based on the conditions of the patient and the availability of the patient&#39;s medical records at different time points. The timeline allows the healthcare professional  100  to monitor the patient&#39;s health and disease progression over time. 
     The healthcare professional  100  can scroll through the timeline, as a graphical input, by “touching” a graphical indicium of the timeline with one of his fingers and “move” the finger to the right, for example, corresponding to moving from a first time point to a later second time point. Image sensors on the eyewear  106  can monitor and capture that movement to determine that the healthcare professional wishes to scroll from the first time point to the second time point. Once the holographic eyewear  106  determines that such a “touch” and “movement” have occurred, the holographic eyewear  106  can display updated medical record content items on the 3D avatar  106 . For example, at the first time point, the patient may have liver cancer, and the holographic eyewear  106  can display the medical records relating to the liver cancer as a medical record content item appearing spatially near the 3D avatar&#39;s liver. The liver cancer may have metastasized to the patient&#39;s lung and brain at the second time point. When the healthcare professional  100  scroll to the second time point, the holographic eyewear  106  can display the medical records relating to the metastasis as two medical record content items appearing spatially near positions of the 3D avatar corresponding to the lung and brain. 
     Record Creation 
       FIG. 4  is a schematic illustration showing the creation of a new medical record and pinning of the new medical record on a 3D avatar by a healthcare professional  100 . During a doctor visit or a hospital visit, the patient may inform the healthcare professional  100  that he is suffering from a new disease or symptom, for example a fracture of the left ankle  112 D. To create a new medical record of the fracture of the left ankle  112 D, the healthcare professional  100  can “touch” a displayed graphical representation of a submenu content item for creating a new “audio” record. In some embodiments, as the healthcare professional  100  captures and records the new medical record, the holographic eyewear  106  can display a timeline, for example the timeline  302  illustrated in  FIG. 3 , to the healthcare professional  100 . 
     When the holographic eyewear  106  determines that the healthcare professional  100  has “touched” the displayed graphical representation of the submenu content item for recording a new audio medical record, the holographic eyewear  106  can update the display to show a recording menu content item  400  for recording the new audio medical record. The graphical representation of the recording menu content item  400  can include one or more submenu content items  402 A-D. Non-limiting examples of the one or more new submenu content items include a submenu content item  402 A for recording the new audio medical record, a submenu content item  402 B for pausing the recording of the new audio medical record, a submenu content item  402 C for rewinding while recording the new audio medical record, and a submenu content item  402 D for fast forwarding while recording the new audio medical record. 
     Once the holographic eyewear  106  displays the recording menu content item  400  to a healthcare professional  100 , he can interact with it by “touching” a displayed graphical representation of the submenu content item  402 A for recording the new audio medical record. In one example, the eyewear  106  includes one or more sensors that detect the positions of the healthcare professional&#39;s fingers to determine that the content item has been “touched.” The holographic eyewear  106  can include one or more microphones for recording the new audio medical record. Once the new audio medical record is created, the healthcare professional  100  can pin  412  the new audio medical record to a pinning location on the left ankle of the 3D avatar  102 . The new audio medical record can be displayed as a medical record content item  114 D at the pinning location on the fracture of the left ankle  112 D. The holographic eyewear  106  can request the healthcare professional  100  to confirm pinning  410  of the new medical record content item  114 D to the left ankle of the 3D avatar  102 . In some embodiments, the holographic eyewear  106  can determine the pinning location of the new audio medical record, for example, the left ankle of the 3D avatar  102  without the healthcare professional  100  having to pin the medical record at the pinning location. In some embodiments, the holographic eyewear  106  can request the healthcare professional  100  to confirm the pinning location of the new medical record content item  114 D that it determines. During subsequent interactions between the healthcare professional  110  and the holographic eyewear  106 , it can display the medical record content item  114 D to the healthcare professional  110  and other healthcare professionals, at the pinning location.

     Sensors 
     The holographic eyewear can include one or more of the motion sensor  514 A, the orientation sensor  514 B, the image sensor  514 C, the microphone  514 D, and the location sensor  514 E. The motion sensor  514 A can be configured to sense, detect, and determine the movements of the healthcare professional  100  wearing and operating the holographic eyewear  106 , for example the healthcare professional&#39;s head nod. As illustrated with reference to  FIG. 4 , when the holographic eyewear  106  requests the healthcare professional  100  confirm the pinning  412  of the new medical record content item  114 D to the left ankle of the 3D avatar  102 , the healthcare professional  100  can nod his head to indicate his confirmation of the pinning  412  location. In some embodiments, the motion sensor  514 A can convert the healthcare professional&#39;s motions into electrical signals for processing by the command determiner  540 . 
     Referring to  FIG. 5 , in some embodiments, the motion sensor  514 A can comprise a single axis accelerometer configured such that the accelerometer can sense, detect, and determine the movements imparted on the holographic eyewear  106  by the healthcare professional  100 . In some embodiments, the motion sensor  514 A can comprise multiple accelerometers, for example single axis accelerometers and 3D accelerometers, to enable detection of direction movement and vibrations in a multiplicity of directions and to increase detection sensitivity. 
     The orientation sensor  514 B can be configured to determine the orientation of the healthcare professional&#39;s head relative to a fixed plane, for example the floor of an examination room in a hospital where the healthcare professional  100  is performing an examination. For example, the holographic eyewear  106  can be configured to display the 3D avatar  102  at a fixed orientation relative to the fixed plane. When the healthcare professional  100  tilts his head a certain extent, for example  10 °, in one direction, the holographic eyewear  106  can detect such a tilt using the orientation sensor  514 B. In response to detecting such a tilt, the holographic eyewear  106  can tilt the display of the 3D avatar  102  to the healthcare professional  100  the same extent, for example 10°, in the opposite direction. Consequently, the healthcare professional  100  sees that the 3D avatar  102  has a fixed orientation relative to the fixed plane. The orientation of the 3D avatar  102  relative to the fixed plane does not change when the orientation of the holographic eyewear  106  changes. In some embodiments, the orientation sensor  514 B can convert orientation information into electrical signals for processing by the command determiner  540 . 
     The holographic eyewear  106  can include, for example, two image sensors  514 C.

One of the two image sensors  514 C can be located spatially near the left eye of the healthcare professional  100  and be oriented such that it captures some or all of what the healthcare professional&#39;s left eye sees. The other of the two image sensors  514 C can be located spatially near the right eye of the healthcare professional  100  and be oriented such that it detects some or all of what the healthcare professional&#39;s right eye sees. In some embodiments, the two image sensors  514 C convert photons into electrical signals and images for processing by the command determiner  540 . In some embodiments, the holographic eyewear  106  can combine, using the processor  506 A and the memory  508 A, the images from the two image sensors  514 C to create stereoscopic images of what the healthcare professional  100  sees with his two eyes. In some embodiments, the holographic eyewear  106  can include one image sensor  514 C. The image sensor  514 C can be located between the two eyes and be oriented such that it detects and approximates what the healthcare professional  100  sees with his two eyes. In some embodiments, the image sensor  514 C can be located at other locations on the holographic eyewear  106 . 
     The holographic eyewear  106  can capture what the healthcare professional  100  sees in his field of view using one or more image sensors  514 C. In some embodiments, the holographic eyewear  106  can capture more or less than what the healthcare professional  100  sees in his field of view using the image sensors  514 C. As illustrated with reference to  FIG. 1 , when the healthcare professional  100  sees, through the holographic eyewear  106 , that one or more of his fingers, hands, arms, legs, or one or more objects he is connected with, come into contact with a content item, the holographic eyewear  106  can determine that such a contact has occurred. The holographic eyewear  106 , using the image sensors  514 C, can determine that such a contact has occurred. Consequently, the holographic eyewear  106  can capture and “see” the visual commands that the healthcare professional  100  gives to the holographic eyewear  106 . In some embodiments, the holographic eyewear  106  can create a new video medical record or a new image medical record using the image sensors  514 C. 
     The microphone  514 C can be configured to detect sound from the environment surrounding the holographic eyewear  106  and from the healthcare professional  100 . The holographic eyewear  106  detects and “hears” what the healthcare professional  100  hears and says. As illustrated with reference to  FIG. 4 , when the holographic eyewear  106  requests the healthcare professional  100  confirm the pinning  412  of the new medical record content item  114 D to the left ankle of the 3D avatar  102 , the healthcare professional  100  can say “yes” to indicate his confirmation of the pinning  412  location. In some embodiments, the microphone  514 C can convert acoustic waves into electrical signals for processing by the command determiner  540 . 
     Referring to  FIG. 5 , the location sensor  514 D can be configured to determine the location of the healthcare professional  100  based on the location of the holographic eyewear  106 . Non-limiting examples of the location sensor  514 D includes global positioning system (GPS) and assisted GPS (aGPS) transceivers. The holographic eyewear&#39;s responses to the healthcare professional&#39;s commands can be based on the location of the healthcare professional  100 . The holographic eyewear  106  can allow or deny the healthcare professional&#39;s commands based on the location of the healthcare professional  100 . For example, if the holographic eyewear  106  determines that the healthcare professional  100  is outside a hospital, he may be prohibited from accessing any confidential patient information. In some embodiments, the holographic eyewear  106  can adjust, rearrange, or reorganize the user menu  120 , the various content items, and the 3D avatar  102  based on the location of the healthcare professional  100 . For example, if the healthcare professional  100  is at a hospital cafeteria, the healthcare professional  100  may not be authorized to order tests for patients. Thus, user menu  120  may not display the “order tests” main menu content item  122 B and the submenu content items  140  such as order “MRI”  140 A, “X-ray”  140 B, “blood test”  140 C, and “more” tests  140 D.

     Privacy is important for healthcare professionals to successfully manage patient healthcare. To maintain patient privacy, the holographic eyewear  106  can include a healthcare professional identifier  524 A in communication with the processor  506 . The healthcare professional identifier  524 A determines the identity of a wearer of the holographic eyewear  106 . Methods for determining the identity of a wearer of the holographic eyewear  106  include image authentication and biometric authentication. For example, the wearer of the holographic eyewear  106  can look into a mirror, and the image sensor  514 C can take a picture of the wearer. Based on the picture of the wearer, the healthcare professional identifier  524 A can determine the wearer&#39;s identity. In some embodiments, the healthcare professional identifier  524 A can send the identity of the wearer to the healthcare professional identifier  524 B of the 3D avatar medical information system  104 . In some embodiments, the healthcare professional identifier  524 A can send the image of the wearer to the healthcare professional identifier  524 B for determination of the wearer&#39;s identity. 
     Based on the wearer&#39;s identity, the holographic eyewear  106  can determine whether the wearer is an authorized healthcare professional and whether an authorized healthcare professional is authorized to carry out certain interactions with the holographic eyewear  106 . For example, if an authorized healthcare professional is a medical doctor, he can be authorized to order tests for his patients and not other patients. If an authorized healthcare professional is a hospital administrative staff, he may be not authorized to order tests for patients. The hospital administrative staff may be authorized to review a patient&#39;s payment history. 
     Avatar Display 
     The holographic eyewear  106  can include an avatar displayer  526  in communication with the processor  506 A. The avatar displayer  526  determines the characteristics of the 3D avatar  102  shown to the healthcare professional  100  on the lenses of the holographic eyewear  106 . Non-limiting examples of the characteristics of the 3D avatar  102  include color, opacity, size, orientation, and location. In some embodiments, the avatar displayer  526  can determine the size of the 3D avatar  102  based on the weight and height of the patient. The avatar displayer  526  can determine the size of the 3D avatar  102  based on, for example, the number and the sizes of the various content items the lenses of the holographic eyewear  106  shows to the healthcare professional  100 . The avatar displayer  526  can determine the location of the 3D avatar  102  based on, for example, the colors, opacities, sizes, orientations, and locations of other objects in the holographic eyewear&#39;s field of view. Non-limiting examples of other objects include patients, doctor office furniture, and medical instruments. For example, the avatar displayer  526  can display the 3D avatar  102  on the lenses of the holographic eyewear  106  such that the 3D avatar  102  coincide with or overlap the patient. As another example, the avatar displayer  526  can display the 3D avatar  102  on the lenses of the holographic eyewear  106  such that the 3D avatar  102  is adjacent to the patient. The avatar displayer  526  can determine the color of the 3D avatar  102  based on, for example, the colors of other objects in the holographic eyewear&#39;s field of view.

In some embodiments, the locations of the medical record content items  114  are the pinning locations decided by the healthcare professional  100  when creating the medical record content item  114 A-D. As illustrated with reference to  FIG. 4 , the pinning location of the medical record content item  114 D can be the left ankle of the 3D avatar  102 , determined by the healthcare professional  100  when creating the medical record content item  114 . In some embodiments, the particular locations may be relative to the location of the 3D avatar  102  on the lenses of the holographic eyewear  106 . 
     As illustrated with reference to  FIG. 1 , the content items  114  can include the medical records  111 . For the content item displayer  530  to display the content items of the “headache” category  112 A, the record retriever  528 A may retrieve some or all of the patient&#39;s medical records  111  of the “headache” category  112 A. When the healthcare professional  100  “touches”  170  the medical record content item  114 B of the “rash” category  112 B, the record retriever  528 A can retrieve some or all of the patient&#39;s medical records  111  of the “rash” category for display by the content item displayer  530 . The content item display  530  can display the patient&#39;s medical records  111  as the updated medical record content item  114 B′ as illustrated with reference to  FIG. 2 . For the content item displayer  530  to display the medical record content items  312 A- 312 C as a timeline, the record retriever  528 A can retrieve some or all of the patient&#39;s medical records  111  of the “burn” category  112 C as illustrated with reference to  FIG. 3 . To display the video medical record of the medical record content item  312 C, the record retriever  528 A can retrieve some or all of the video medical record for display by the content item displayer  530 . 
     Referring to  FIG. 5 , the record creator  532 A (in conjunction with the record creator  532 B of the 3D avatar medical information system  104  and the record creator  532 C of the electronic medical record system  104 ) enables the healthcare professional  100  to create and store new medical records. The electronic medical record system  110  can store new medical records in the storage  510 C. As illustrated with reference to  FIGS. 1 and 4 , to create a new medical record, the healthcare professional  100  can “touch”  174 , for example, the submenu content item  160 B for creating a new “audio” record. When the holographic eyewear  106  determines that the healthcare professional  100  has “touched”  174  the displayed graphical representation of the submenu content item  160 B for recording a new audio medical record, the content item displayer  530  can update the display shown to the healthcare professional  100 . The content item displayer  530  can display the new menu content item  400  for recording the new audio medical record. Once the healthcare professional  100  confirms the creation of the new audio medical record is complete, the record creator  532 A sends the new audio medical record to the record creator  532 B for storage in the storage  510 C by the record creator  532 C of the electronic medical record system  110 . 
     Referring to  FIG. 5 , the record updater  534 A enables the healthcare professional  100  to update the medical records  111  stored in the storage  510 C of the electronic medical record system  110 . In some embodiments, the record updater  534 A can update the contents of existing medical records  111 . The record updater  534 A (in conjunction with the record updater  534 B of the 3D avatar medical information system  104  and the record updater  534 C of the electronic medical record system  110 ) can update the medical records  111  stored in the storage  510 C. In some embodiments, the record updater  534 A (in conjunction with the record creator  532 A) can store the updated medical records as new medical records in the storage  510 C. 
     The record pinner  536 A allows healthcare professionals to pin medical records to locations on the 3D avatar  102  for display as medical record content items. The record pinner  536 A (in conjunction with the command determiner  540 ) can determine the pinning locations. As illustrated with reference to  FIG. 4 , once a new audio medical record is generated, the healthcare professional  100  can pin  412  the new audio medical record to a pinning location. For example, the pinning location can be the left ankle of the 3D avatar  102 . The new audio medical record can be displayed as a medical record content item  114 D at the pinning location on the left ankle  112 D of the 3D avatar  102 . In some embodiments, the record pinner  536 A can determine the pinning location of the new audio medical record, for example, the left ankle of the 3D avatar  102  without the healthcare professional  100  having to pin the medical record at the pinning location. In some embodiments, the record pinner  536 A can request the healthcare professional  100  to confirm the pinning location of the new medical record content item  114 D. During subsequent interactions between the healthcare professional  110  and the holographic eyewear  106 , the content item displayer  530  can display the medical record content item  114 D at the pinning location provided by the record pinner  536 A. 
     In some embodiments, the record pinner  536 A allows the healthcare professional  110  to update the pinning locations of medical records with existing pinning locations. For example, the content item displayer  530  can display the new audio medical record as the medical record content item  114 D at the pinning location on the left ankle  112 D of the 3D avatar  102 . The healthcare professional  110  can move the pinning location, for example, from the left ankle to the right ankle of the 3D avatar  102 . In some embodiments, the record pinner  536 A allows the healthcare professional  110  to create pinning locations for existing medical records  111  stored in the storage  510 C without existing pinning locations. 
     Once the pinning locations are determined, the record pinner  536 A can send the pinning locations to the record pinner  536 B of the 3D avatar medical information system  104 . The record pinner  536 B can store the pinning locations and the associations between the pinning locations and the medical records  111  in the storage  510 B. The record pinner  536 B can provide the record pinner  536 A with the pinning locations of the medical records  111 , based on the pinning locations and the associations between the medical records  111  in the storage  510 B. The content item displayer  530  can display the medical records  111  at appropriate locations in the healthcare professional&#39;s field of view as the medical record content items  114  based on the pinning locations of the medical records  111  provided by the record pinner  536 B to the record pinner  536 A. 
     Patient Identification 
     The holographic eyewear  106  can include a patient identifier  538  in communication with the processor  506 A. The patient identifier  538  can determine the identities of patients. For example, the patient identifier  538  can determine the identity of the patient the healthcare professional  100  sees through the holographic eyewear&#39;s one or more lenses, based on the images of the patient captured by the image sensors  514 C. In some embodiments, the patient identifier  538  can determine the identity of the patient the healthcare professional  100  sees based on the patient&#39;s voice captured by the microphone  514 C. Based on the identity of the patient determined by the patient identifier  538 , the holographic eyewear  106  can display the appropriate user menu  120 , the appropriate content items, and the appropriate 3D avatar  102  to the healthcare professional  100 . 
     Instrument Identification 
     In some embodiments, the holographic eyewear  106  can include an instrument identifier  539  in communication with the processor  506 A. The instrument identifier  539  can determine the identities of instruments. The identity of an instrument can include, for example, the instrument&#39;s make, model, year of manufacture, usage history, and service history. For example, the instrument identifier  539  can determine the identity of the instrument the healthcare professional  100  sees through the holographic eyewear&#39;s lenses, based on the images of the instrument captured by the image sensors  514 C. In some embodiments, the instrument identifier  539  can determine the identity of the instrument the healthcare professional  100  based on the sound wave emitted by the instrument captured by the microphone  514 C. Based on the identity of the instrument determined by the instrument identifier  539 , the holographic eyewear  106  can display, for example, an instruction menu of the instrument for the healthcare professional  100  to review. 
     Command Determination 
     The holographic eyewear  106  can include a command determiner  540  in communication with the processor  506 A. The command determiner  540  (in conjunction with the one or more sensors of the holographic eyewear  106 ) can determine the commands the healthcare professional  100  gives to the holographic eyewear  106 . Thus, the healthcare professional  100  can interact with the holographic eyewear  106  and the 3D avatar medical information system  104  through the command determiner  540  and the one or more sensors  514 . 
     In some embodiments, the one or more image sensors  514 C are located and oriented on the holographic eyewear  106  such that they can capture what the healthcare professional  100  sees. The holographic eyewear  106 , using the image sensors  514 C, can capture and “see” the movements of the healthcare professional&#39;s fingers, hands, arms, legs, and one or more objects he is connected with. The command determiner  540 , based on the images captured by the image sensors  514 C, can determine that these movements are visual commands given by the healthcare professional  100 . Based on the visual commands, the holographic eyewear  106  can update the display shown to the healthcare professional  100  on its lenses. As illustrated with reference to  FIG. 1 , the command determiner  540  (in conjunction with the image sensors  514 C) can determine that healthcare professional  100  has “touched” the graphical representation of a content item. Based on the identity of the content item, the command determiner  540  can determine the specific command given by the healthcare professional  100 , for example to see a disease timeline. As illustrated with reference to  FIG. 2 , the command determiner  540  can determine that the healthcare professional  100  has moved two of his fingers away from each other  204 . Based on the specific movement, the command determiner  540  can determine the specific command given by the healthcare professional  100 , for example, to zoom in on the updated medical record content item  114 B′. 
     Referring to  FIG. 5 , in some embodiments, the holographic eyewear  106 , using the one or more motion sensors  514 A, can detect the healthcare professional&#39;s head nods. The command determiner  540 , based on the electrical signals produced by the motion sensor  514 A, can determine that these movements are motion commands given by the healthcare professional  100 . Based on the motion commands, the holographic eyewear  106  can update the display shown to the healthcare professional  100 . 
     In some embodiments, the holographic eyewear  106 , using the one or more microphones  514 C, can determine the words that the healthcare professional  100  has said. The command determiner  540 , based on the signals produced by the one or more microphones  514 C and one or more speech recognition methods, can determine that the words are verbal commands given by the healthcare professional  100 . Based on the verbal commands, the holographic eyewear  106  can update the display shown to the healthcare professional  100 . 
     Instructions in the command determiner  540  can configure the processor  506 A to determine the commands given by the healthcare professional  100 . In some embodiments, the command determiner  540  can include instructions that configure the processor  506 A to interpret and apply one or more filters to the data received from the one or more sensors. For example, the command determiner  540  can include instructions that configure the processor  506 A to apply one or more filters to interpret the acoustic waveforms captured by the microphone  514 C, for example, to remove noise from the healthcare professional&#39;s environment captured by the microphone  514 C. 
     Instructions in the command determiner  540  can also configure the processor  506 A to extract command parameters from the data received by the one or more sensors. Non-limiting examples of command parameters include the types of commands and the numeric values of the commands. As illustrated with reference to  FIG. 2 , the command determiner  540  can determine that the healthcare professional  100  has moved two of his fingers away from each other  204 . The command type for such movement can be, for example, zoom in or zoom out. The command parameter can be, for example, the extent of zoom in based on the magnitude of the two fingers moving away from each other. Therefore, instructions in the command determiner  540  may configure the processor  505 A for interpreting, filtering, and analyzing the signals, whether raw or processed, from sensors. 
     Task Workflow Displayer 
     The holographic eyewear  106  can include a task workflow displayer  544 A in communication with the processor  506 A. The 3D avatar medical information system  104  can include the task workflow displayer  544 B in communication with the processor  506 B. The task workflow displayer  544 A, with the task workflow displayer  544 B, can determine the appropriate instructions the healthcare professional  100  should follow for a given task. The task workflow displayer  544 A can store instructions the healthcare professional  100  should follow for various tasks in the storage  510 A. In some embodiments, the task workflow displayer  544 B can store instructions the healthcare professional  100  should follow for various tasks in the storage  510 B. The task workflow displayer  544 B can provide the task workflow displayer  544 A with instructions stored for various tasks stored in the storage  510 B that the healthcare professional  100  should follow. 
     For example, to locate veins in a patient&#39;s arm for blood draw, the task workflow displayer  544 A can display instructions, on the holographic eyewear&#39;s lenses, to the healthcare professional  100  that he should follow in order to successfully locate veins in the patient&#39;s arm for blood draw. For example, to insert a catheter into a patient, the task workflow displayer  544 A can display instructions, on the holographic eyewear&#39;s lenses, to the healthcare professional  100  that he should follow in order to successfully insert a catheter into the patient. In some embodiments, the task workflow displayer  544 A can display instructions to the healthcare professional  100  to facilitate his compliance with procedures mandated by the hospital, the city, the state, or the federal government. 
     Communication between the Eyewear, the 3D Avatar Medical Information System, and the Electronic Medical Record System

     It is also noted that the examples may be described as a process, which is depicted as a flowchart, a flow diagram, a finite state diagram, a structure diagram, or a block diagram. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel, or concurrently, and the process can be repeated. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed. A process may correspond to a method, a function, a procedure, a subroutine, or a subprogram, etc. When a process corresponds to a software function, its termination corresponds to a return of the function to the calling function or the main function. 
     Those of skill in the art will understand that information and signals may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the present disclosure may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof. 
     The above detailed description is directed to certain specific embodiments of the invention. However, the invention can be embodied in a multitude of different ways. It should be apparent that the aspects herein may be embodied in a wide variety of forms and that any specific structure, function, or both being disclosed herein is merely representative. Based on the teachings herein one skilled in the art should appreciate that an aspect disclosed herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways, without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of the invention. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, such an apparatus may be implemented or such a method may be practiced using other structure, functionality, or structure and functionality in addition to or other than one or more of the aspects set forth herein. 
     In at least some of the previously described embodiments, one or more elements used in an embodiment can interchangeably be used in another embodiment unless such a replacement is not technically feasible. It will be appreciated by those skilled in the art that various other omissions, additions and modifications may be made to the methods and structures described above without departing from the scope of the claimed subject matter. All such modifications and changes are intended to fall within the scope of the subject matter, as defined by the appended claims. 
     Furthermore, the system and methods described herein may be implemented by a 3D avatar medical information system and a holographic eyewear in communication with a computing device. These include mobile and non-mobile devices, as well as general purpose or special purpose computing system environments or configurations. Examples of computing systems, environments, and/or configurations that may be suitable for use with the invention include, but are not limited to, personal computers, server computers, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like. Further, the systems and methods may be implemented in mobile devices. Non-limiting examples of mobile devices include phones, smartphones, Personal Digital Assistants (PDAs), Ultra-Mobile Personal Computers (UMPCs), and Mobile Internet Devices (MIDs). 
     As used herein, the term “determining” encompasses a wide variety of actions. For example, “determining” may include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like. Also, “determining” may include resolving, selecting, choosing, establishing and the like. 
     With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. 
     It should be understood that any reference to an element herein using a designation such as “first,” “second,” and so forth does not generally limit the quantity or order of those elements. Rather, these designations may be used herein as a convenient method of distinguishing between two or more elements or instances of an element. Thus, a reference to first and second elements does not mean that only two elements may be employed there or that the first element must precede the second element in some manner. Also, unless stated otherwise a set of elements may comprise one or more elements. In addition, terminology of the form “at least one of: A, B, or C” used in the description or the claims means “A or B or C or any combination of these elements.” 
     As used herein, a phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover: a, b, c, a-b, a-c, b-c, and a-b-c. 
     It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g.,“a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g.,“a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” 
     In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group. 
     As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into sub-ranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having  1 - 3  articles refers to groups having 1, 2, or 3 articles. Similarly, a group having 1-5 articles refers to groups having 1, 2, 3, 4, or 5 articles, and so forth. 
     The steps of a method or process described in connection with the implementations disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two.
