In the following description, numerous specific details are set forth in order to provide a thorough understanding of the presented concepts. The presented concepts may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail so as to not unnecessarily obscure the described concepts. While some concepts will be described in conjunction with the specific embodiments, it will be understood that these embodiments are not intended to be limiting.
A wearable personal digital (WPD) device for facilitating mobile device payments and personal use and related methods are described herein. The WPD device may include a housing enclosing all components of the WPD device and a band attached to the housing. Furthermore, the WPD device may perform a function of a health and activity monitor. More specifically, the WPD device may sense biometric data associated with the user (blood pressure, heart rate, temperature, and so forth) using biometric sensors and/or receive data on user movements using accelerometers or a Global Positioning System (GPS) unit. Biometric data and user movement data may be shown on a display of the WPD device, stored in a memory unit of the WPD device, and/or processed by a processor of the WPD device to produce historical or averaged data.
The WPD device may be communicatively coupled with an external device, such as a smartphone. The WPD device and the smartphone may communicate using a wireless network, such as a Wi-Fi network or a Bluetooth network. The WPD device may display notifications from the smartphone. The notifications may represent receipt of any type of data by the smartphone, for example, a phone call, a message, an upcoming calendar event, a social network event, and the like. A user may respond to the notification directly via the WPD device, or using the smartphone. The biometric data and user movement data collected by the WPD device may be sent to the smartphone for further processing.
The display of the WPD device may be represented by a touchscreen. The user may provide commands to the WPD device by varying the time of user interaction with the touchscreen. More specifically, the user may vary the time of pressing the touchscreen. Different time of pressing the touchscreen may correspond to different commands.

During the payment transaction, an amount of money corresponding to a price of the product may be transferred from a user payment account to a merchant payment account. The price of the product may be included into the product information. The payment transaction may be performed by sending payment data by a NFC unit of the WPD device to a merchant using a NFC.
In an example embodiment, the NFC may be used for payments for purchases made online and offline. A user of the WPD device 200 equipped with the NFC unit may perform transactions without authentication, or some authentication may be needed, such as a Personal Identification Number (PIN), before transaction is completed. The payment can be deducted from a pre-paid account of the user or charged directly to a bank account of the user. In example embodiment, the NFC unit may enable the WPD device 200 to establish radio communication with external devices by touching the WPD device 200 and the external device together or bringing them into proximity.
In an example embodiment, the camera 212 may be further operable to track a face, fingers, and gestures of the user. In turn, the processor may be operable to analyze the face, the fingers, and the gestures tracked by the camera. Additionally, the processor may recognize speech and subtract a background noise from the speech.
The camera 212 may be further operable to perform an optical character recognition of a data.

In a further example embodiment, the WPD device 200 may be adapted to display a unique code to be scanned by a Point-of-Sale (POS) system. FIG. 3 shows a schematic representation 300 of scanning a barcode 305 displayed on the WPD device 200 by a barcode scanner 310 of the POS system 315. The barcode 305 may encode a user payment information, such as a bank account, a payment card number, and so forth. The barcode 305 may be generated by a payment system (not shown) associated with the WPD device 200 or the external device. Therefore, the user may use the barcode 305 instead of a debit card or a credit card.
Referring back to FIG. 2, the front view 210 of the WPD device 200 shows an example embodiment, according to which the WPD device 200 includes a swipe card reader 214 communicatively coupled to the processor. The swipe card reader 214 may be located on either side of the WPD device 200, vertically or horizontally. The swipe card reader 214 may be operable to read data of a payment card. Upon reading, the data may be transmitted to the processor of the WPD device 200 or to the external device. The swipe card reader 214 may be used, for example, during performing payments on-line. Furthermore, the swipe card reader 214 may be used for providing user payment information, which may be further encoded into a barcode 216. The barcode 216 may be displayed on the display 204, e.g., in a store, for performing the payment transaction.
The biometric parameters sensed by the biometric sensors may be stored to the memory unit of the WPD device 200. According to another embodiment, the biometric parameters sensed by the biometric sensors may be transmitted to the external device for further processing or displaying on the external device. The processor may be operable to provide data associated with biometric parameters to be displayed on the display 204. The biometric parameters may include one or more of the following: a blood pressure, a heart rate, a glucose level, a body temperature, an environment temperature, arterial properties of the user, and the like. The biometric sensors may be disposed within the band. Based on detection that the one or more of the biometric parameters of the user exceed predetermined limits, the biometric sensors may be configured to produce the alarm. In an example embodiment, the biometric sensors include lenses operable to use infrared light-emitting diodes (LED) and visible-light LEDs to sense a heart rate of the user. In a further example embodiment, the biometric sensors may be operable to non-invasively monitor a glucose level. The glucose level may be monitored using a saliva testing.
The biometric sensors may further include a skin contact sensor data engine. The skin contact sensor data engine may be operable to monitor a user electrocardiogram or the heart rate. The user electrocardiogram and the heart rate may serve as identification and personal data of the user. The skin contact sensor data engine may be further operable to prompt the user to enter a PIN after placing the WPD device 200 on the wrist. The skin contact sensor data engine may associated the PIN with the user electrocardiogram and the heart rate. Therefore, in case of placing the WPD device 200 on a wrist of another user, another user may be not authorized to user the WPD device 200 because a user electrocardiogram and a heart rate of another user may differ from those of the user of the WPD device 200.
The haptic touch control actuator may be operable to produce a haptic feedback in response to one or more events. The one or more events may include receiving of the alert, receiving of a notification, a confirmation, movement of the WPD device 200, receiving of the user input, sensing of the one or more biometric parameters, and so forth. The haptic feedback may be sensed by the user body, such as a wrist of the user. The haptic feedback may have a plurality of feedback types. More specifically, each of the one or more events may be associated with one of the plurality of feedback types.
In a further example embodiment, the display 204 may be further operable to display data associated with the activity of the user. The activity of the user may include calories burned, sleep quality, breaths per minute, snoring breaks, steps walked, distance walked and the like. The activity of the user may be tracked by the activity tracking sensors of the WPD device 200. The activity tracking sensors may be operable to monitor user movements in a three-dimensional trajectory, identify type of user activity, identify a specific motion fingerprint of an exercise, evaluate user physical form, count repetitions, calculate calories burned, and so forth. In certain example embodiments, the activity tracking sensors may sense and track position of the user to identify the snoring of the user and provide a notification to the user, e.g. using the vibration, to force the user to change the position. In an example embodiment, the activity tracking sensors are operable to track snoring of the user and, based on tracking of the snoring, produce an alarm to the user to break snoring.
In an example embodiment, the WPD device 200 may further include a microphone (not shown). The microphone may be operable to sense voice data. The voice data may be obtained from the user. For example, the user may provide a user request using user voice. The voice data may include a voice command, a voice memo, a voice message, and the like. The voice data may be transmitted to the processor for further processing. In particular, the processor may be operable to recognize the voice data in order to obtain the user request. The user request may be transmitted to the external device.
In an example embodiment, the input unit 206 may include a clock crown located on any of lateral sides of the housing, an upper side of the housing, or a bottom side of the housing. The processor may be operable to sense the rotational motion of the input unit 206. For example, the user may rotate the input unit 206. Based on the sensing, the data displayed on the display 204 may be scrolled. Each action performed by the user on the input unit 206, such as direction of rotation (e.g., clockwise or counter clockwise), speed of rotation, pressing the input unit 206 towards the housing 202, or extending the input unit 206 outwards the housing 202, may correspond to a specific command.
In a further example embodiment, the processor of the WPD device 200 may be operable to control an operation of a camera of the external device. Furthermore, the processor may access audio files stored on the external device and wirelessly connect with earphones. Upon accessing the external device and connecting with the earphones, the processor may reproduce the audio files using the earphones. Therefore, the user of the WPD device 200 may listen to the music stored on the external device and control reproducing of the audio files using the WPD device 200.
In an example embodiment, the processor may be further operable to generate a code encoding user payment data and user personal data. The generation may be performed based on the user payment data and the user personal data stored in the memory unit of the WPD device 200. The processor may be further operable to prompt the user to touch the display to scan user fingerprints. Additionally, the processor may be further operable to determine a heart rate of the user using the biometric sensors. The processor may be further operable to compare the user fingerprints and the heart rate of the user with reference fingerprints and a reference heart rate. The reference fingerprints and the reference heart rate may be stored in the memory unit. The processor may detect a match of the user fingerprints with the reference fingerprints and of the heart rate of the user with the reference heart rate. Base of the detecting, the processor may provide the code to a merchant digital device for performing a payment transaction. Upon the payment transaction, a payment confirmation may be provided to the user. The payment confirmation may be provided using the haptic feedback.
In an example embodiment, the processor may be further operable to detect current user location, e.g. using a GPS unit. The processor may be operable to detect presence of premises associated with the user in proximity to the current user location. The premises may include a home, an office, a garage, a car, and the like. Based on the detecting, the processor may be operable to initiate unlocking of the premises.
In a further example embodiment, the processor of the WPD device 200 may be operable to detect presence of another WPD device in proximity to the WPD device 200. Based on the detecting, the processor may be operable to initiate data transmission between the WPD device 200 and another WPD device.
In an example embodiment, the processor may be further operable to receive, from the user, a content access request for at least one content item of content data stored in the memory unit of the WPD device 200. The processor may read access rules stored in the memory unit. The access rules may be associated with use of the at least one content item. Based on the access rules, the processor may be operable to determine that an access to the at least one content item is permitted.
