## Background
BACKGROUND OF THE INVENTION
A conventional mobile computing unit is configured to perform a variety of different applications. For example, the mobile unit may utilize an application featuring an augmented reality. Conventional augmented reality relates to a live (direct or indirect) view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics, or GPS data. It is related to a more general concept called mediated reality in which a view of reality is modified by a processor. Augmentation is conventionally performed in real-time and in semantic context with environmental elements (e.g., sports scores on a media broadcast during a game). Through further features (e.g., adding computer vision and object recognition), the information about the surrounding real world of the user becomes interactive and digitally manipulable. In one manner of augmented reality, artificial information about the environment and its objects are overlaid on the real world.
In a specific example of augmented reality, the mobile unit may be used to capture data such as in a barcode. Accordingly, the mobile unit may include a scanning engine. To provide the augmented reality, the mobile unit may further include an imager such that a display device shows a field of view of the imager thereon in real time. A user of the mobile unit or a data capture application utilizes the visual data shown on the display device. However, this provides a sub-optimal experience, particularly to the user. Initially, a user desires a very wide, unobstructed field of view to most easily acquire an item for data capture. Furthermore, the user requires a real-time view with instantaneous responses to movements. These two needs are difficult to achieve using an imager to provide a field of view on the display device. Specifically, the imager can only show the field of view that is capable of being used by the user on the display device; the imager is required to capture the image data which must first be processed prior to showing the image data on the display device; and finally, the image data must be rendered on the display device. During this process, significant power and processing power is required while the imager must remain activated in order to capture the image data as well as video data for the augmented reality view. The processing required for this procedure ultimately leads to a lag or delay in what an imager captures to what is shown to the user. For example, the user may be required to hold the imager in a common position for a predetermined amount of time to guarantee that what is being shown on the display device corresponds to what is being viewed.
Accordingly, there is a need for a mobile unit including a data capture application that requires less power, less processing power, and a genuine real-time view providing an instantaneous response to movements.

DETAILED DESCRIPTION OF THE INVENTION
An electronic device comprises a housing including a first coupling component; a data acquisition device configured to capture first data within a first field of view (FOV); and a display device comprising a viewable portion configured to display second data, the viewable portion being at least semi-transparent and a second coupling component disposed at least partially on the viewable portion and coupling with the first coupling component to couple the display device to the housing, wherein when the first and second coupling components are coupled, the display device is positioned in such a manner that a second FOV viewed through the viewable portion is viewable by a user, wherein the first FOV of the data acquisition device is within at least a portion of the second FOV of the viewable portion.
The exemplary embodiments may be further understood with reference to the following description and the appended drawings, wherein like elements are referred to with the same reference numerals. The exemplary embodiments describe a mobile unit (MU) including a display device that enables a user to view a desired area therethrough. Specifically, the display device may be configured as substantially transparent such that the user is able to view the desired area through the display device itself. The MU may be designed such that there are no components that impede the view of the user through the display device. The MU, the display device, the transparency, and applications thereof will be discussed in further detail below.
FIGS. 1 and 2 show a MU 100 in accordance with some embodiments. Specifically, FIG. 1 shows the MU 100 including a transparent display device 120 and other components in accordance with some embodiments. FIG. 2 is a perspective view of the MU 100 of FIG. 1 in accordance with some embodiments. In particular, FIG. 2 shows an exemplary design of the MU 100. The MU 100 may be any portable device such as a mobile phone, a personal digital assistant, a smartphone, a tablet, a laptop, a barcode reader, etc. Accordingly, the MU 100 may be a handheld device in which the user is capable of moving the MU 100. The MU 100 may include a housing 105, a processor 110, a memory arrangement 115, a display device 120 (e.g., a transparent display device), a transceiver 125, an input/output (I/O) device 130, a data acquisition device (DAD) 135, an aimer 140, and a coupling 150. However, it should be noted that the MU 100 may include further components such as a scanning engine, sensors, a portable power supply (e.g., battery), a lighting arrangement, etc.
The housing 105 may be any component configured to at least partially dispose the components therein. According to the exemplary embodiments, the housing 105 may house the processor 110, the memory arrangement 115, the transceiver 125, the I/O device 130, the DAD 135 and the aimer 140. As will be more clear below, the I/O device 130, the DAD 135, and the aimer 140 may be at least partially disposed in the housing 105 such that at least a portion thereof is exposed to an exterior to enable a respective functionality. According to the exemplary embodiments, the housing 105 may also be designed with a pistol grip 145 (shown in FIG. 2). The design of the housing 105 is also configured such that the display device 120 is coupled thereto in a manner that a view through the display device 120 is not impeded by any portion of the housing 105 (or any other component of the MU 100).
The processor 110 may provide conventional functionalities for the MU 100. For example, the MU 100 may include a plurality of applications that are executed on the processor 110 such as an application including a web browser when connected to a communication network via the transceiver 125. In a specific exemplary embodiment, the processor 110 may execute a data capture application such as receiving a barcode and decoding the data therein. The memory 115 may also provide conventional functionalities for the MU 100. For example, the memory 115 may store data related to operations performed by the processor 110. The transceiver 125 may be any conventional component configured to transmit and/or receive data. The transceiver 125 may therefore enable communication with other electronic devices directly or indirectly through a network.
The display device 120 may be any component configured to show data to a user. According to the exemplary embodiments, the display device 120 may be designed in a substantially transparent manner such that a user is capable of viewing beyond the display device 120. Further functionalities of the display device 120 may also be included. For example, the I/O device 130 may be any component configured to receive an input from the user. The display device 120 may incorporate the I/O device 130, particularly when the I/O device 130 is a touch sensing pad including an area in which the user may enter inputs. Specifically, the I/O device 130 may be a transparent touch sensor placed on top of the display device 120 that enables a user to enter inputs on a surface of the display device 120. It should be noted that the I/O device 130 may be any conventional type that is at least partially disposed in the housing 105. For example, the I/O device 130 may be a keypad (e.g., alphanumeric keypad, numeric keypad, etc.) or a touch sensing pad for a user to enter inputs manually with a finger(s) or a stylus. In another example and according to the exemplary embodiments, the I/O device 130 may include a trigger disposed at least partially on the housing 105, specifically the pistol grip 145. The trigger enables the data capture application to perform its functionality as well as other components related to the data capture application.
The DAD 135 may be any component configured to capture data. For example, the DAD 135 may be an imager configured to capture an image in a field of view (FOV) thereof. In another example, the DAD 135 may be an imager configured to capture a plurality of temporally consecutive images in the FOV. In yet another example, the DAD 135 may be a barcode scanner. According to the exemplary embodiments, the DAD 135 may further be configured as a scanning engine such that the data capture application is capable of extracting data of a barcode. It should be noted that the use of the barcode is only exemplary. Those skilled in the art will understand that the exemplary embodiments relate to data capture in any form such as an encoded form. Accordingly, the barcode may represent a 1-dimensional barcode, a 2-dimensional barcode, an encoded string, a radio frequency identification (RFID) tag, etc. Furthermore, the DAD 135 may also be configured as any data capture component. As the barcode used herein relates to any type, the DAD 135 may include or correspond to a respective data capture engine. For example, if the data capture is for a RFID tag, the DAD 135 may be a RFID receiver or include this component to allow for the respective functionality.
According to a first exemplary embodiment, when the DAD 135 is a 1-dimensional barcode, the DAD 135 may be configured to emit a laser typically in a line. The laser may be emitted toward a barcode in which a return signal is received in order to capture the data of the 1-dimensional barcode. According to a second exemplary embodiment, when the DAD 135 is an imager, the DAD 135 may be configured to emit an indicator such as a projected frame or point that indicates a direction that the DAD 135 is pointing. Therefore, the projected frame or point may be a portion of an entire FOV of the display device 120. According to a third exemplary embodiment, when the DAD 135 is an imager, the DAD 135 may capture an image that includes at least one data capture target such that the image is processed to extract data included in the at least data capture target. For example, the DAD 135 may have a FOV that is the same as the FOV of the display device 120.
The aimer 140 may be any component configured to show a user a direction that the DAD 135 is facing. In a specific exemplary embodiment, the aimer 140 may be a laser-based so that, when activated, the user is shown a particular location of the FOV of the DAD 135. Furthermore, the aimer 140 may project a variety of shapes to illustrate the location to the user. For example, the aimer 140 may be a laser pointer in which a point is projected to a location. In another example, the aimer 140 may project a laser frame in which an area is projected to a location such that the area is representative of the FOV of the DAD 135. It should be noted that the aimer 140 may be oriented such that the projected pattern coincides with the FOV of the DAD 135. As discussed above, the I/O device 130 may include a trigger. The trigger may be configured as a two-phase operation. In a first, initial phase, the trigger may be pressed a predetermined amount such that the aimer 140 is activated. In a second, subsequent phase, the trigger may be pressed a remaining amount such that the DAD 135 is activated.
The coupling 150 may be any component or plurality of components that couple the display device 120 to the housing 105. In a first example, the coupling 150 may be a first portion of the display device 120 that couples to a second portion corresponding to the first portion of the housing 105. In a second example, the coupling 150 may be a bezel extending from the housing 105 in which the display device 120 is attached thereto. The coupling 150 may include connectors such that data may be transmitted between the display device 120 and the processor 110. If the coupling 150 only provides an attachment feature, the MU 100 may include a further connector (e.g., wire connector) separate from the coupling 150 that allows for the data to be transmitted therebetween.
According to the exemplary embodiments, the display device 120 may be configured to enable a user to view therethrough such that a location behind the display device 120 may be viewed (relative to the user facing the MU 100). For example, a barcode may be present on an item that the user wishes to data capture. As discussed above, a conventional manner of data capture includes an imager continuously capturing image data, processing the image data, and rendering corresponding images on a conventional display device. The display device 120 according to the exemplary embodiments eliminates the requirement that the DAD 135 is used for this functionality. That is, the display device 120 allows the user to view a location without the DAD 135 capturing image data used to be shown on a display. In this respect, the display device 120 lowers the necessary power consumption for a data capture functionality to be performed. Furthermore, as no image data processing/rendering is required, less overall processing power is required. In addition, as the user is directly viewing a location through the display device 120, a genuine real-time view of the location is provided (e.g., when the user moves the MU 100).
It should be noted that the display device 120 may be designed in a variety of manners to enable the user to view therethrough. In a first example and as discussed above, the display device 120 may be fully transparent. That is, the materials used to manufacture the display device 120 may include no components that impede a view therethrough. When the display device 120 is fully transparent, the display device 120 may also be configured to overlay other data thereon. For example, the other data may relate to an item being captured. To maintain the transparent aspect of the display device 120 in an overall manner, the overlay of data on the display device 120 may be substantially transparent such that the user is capable of viewing beyond the overlay of data as well. In a second example, the display device 120 may be semi-transparent. That is, the display device 120 may be partially opaque. In this manner, the user is able to see data shown on the display device 120 but still view a location behind the display device 120. In a third example, the display device 120 may include properties that adjust the transparency thereof For example, the display device 120 may be manufactured with crystals or other material that may be activated to remove the transparency of the display device 120. Accordingly, the user is able to clearly see data shown on the display device 120. However, when the user wishes to view a location behind the display device 120, the crystals may deactivated to cause the display device 120 to become fully or semi-transparent. For example, the crystals may be activated/deactivated as a function of an angle at which the MU 100 is disposed such as an upward angle causing the display device 120 to be transparent, while a downward angle causes the display device 120 to become opaque. It should be noted that the crystals may be used in a dynamic manner. That is, select portions of the display device 120 may be opaque while other portions are transparent. The fully and semi-transparent display device 120 may also include select portions which may remain permanently opaque. It should also be noted that the display device 120 may be configured to compensate for various lighting effects. For example, when the user is in an area with a very high illumination that creates a glare or otherwise difficult to view data on the display device 120, the materials of the display device 120 may be manually selected or automatically altered to compensate for the illumination conditions. In another example, the display device 120 may increase or provide a backlight such that data may be viewed particularly in a low illumination environment.
It should be noted that the MU 100 may include additional components related to adjusting a view of the display device 120, particularly when the display device 120 is fully or semi-transparent. In a first example, an opaque cover may be manually placed behind the display device 120 to enable the user to clearly view the data shown on the display device 120. In a second example, a retractable cover may be included that may be extended to cover an area behind the display device 120.
It should also be noted that the display device 120 may include a border or perimeter that is included in a variety of manners. In a first example, the border of the display device 120 may be of an opaque material. Thus, the display device 120 may include a defined border. In a second example, the border of the display device 120 may also be transparent. The view through the display device 120 encompasses a portion of an overall view seen by the user. In addition, visual discontinuities are eliminated from the edges. In a third example, the display device 120 may be coupled to the housing 105 using a transparent bezel such as the coupling 150. In this manner, even the coupling edge of the display device 120 eliminates any visual discontinuity that would otherwise be present.
FIG. 3 is an exemplary use of the MU 100 of FIG. 1 in accordance with some embodiments. FIG. 3 shows a position of the MU 100, a user 200, and a plurality of items 305, 315, 325. The items 305, 315, 325 may include a barcode 310, 320, 330, respectively. FIG. 3 also shows a projected frame 142 from the aimer 140. The user 200 may hold the pistol grip 145. As illustrated, the user 200 is positioned on a first side of the MU 100. The items 305, 315, 325 may be positioned on a second side of the MU 100 opposite the first side such that the items 305, 315, 325 are viewable through the display device 120. The user 200 may activate the trigger of the I/O device 130 such that the aimer 140 is activated to project the frame 142 on the barcode 320. The user 200 also sees the projected frame 142 through the display device 120. Upon fully pressing the trigger, the DAD 135 may be activated such that a data capture functionality is performed. Specifically, the DAD 135 captures an image or reads the barcode 320. As multiple barcodes are present, the DAD 135 may be configured to capture an image of the entire FOV including the plurality of barcodes or the user 200 may manually move the MU 100 to each barcode.
FIG. 4 shows a view from a user's perspective for the exemplary use of FIG. 3 in accordance with some embodiments. For illustrative purposes, FIG. 4 further shows a shelf 400 including supports 405 and a pallet 410 on which the items 305, 315, 325 are placed thereupon. The view from the user's perspective shows that a location behind the display device 120 is viewable by the user 200. The projected frame 142 is also viewable. Accordingly, an entire range of the user may be shown in FIG. 4 with a selected portion thereof shown on the display device 120. Should the user 200 move the MU 100, the view on the display device 120 also adjusts in real time as no processing is necessary. It should noted that the display device 120 including a defined border is only exemplary. As discussed above, the display device 120 may include a transparent border such that no visual discontinuities exist for the user 200 when viewing the entire range of the user 200 and the selected portion on the display device 120.
According to a particular exemplary use of the MU 100, the user 200 ideally holds the MU 100 via the pistol grip 145 such that the user 200 is viewing upward through the display device 200 in a direction of an item to be data captured. The user 200 may press the trigger to a first position (e.g., half-way) to activate the aimer 140. The aimer 140 may generate the projected frame 142. Through the display device 120, the user 200 instantly observes the projected frame 142 projected onto the target item. The user 200 may move the aiming pattern 142 such that the item or barcode to be data captured is reached (such as the position shown in FIGS. 3 and 4). Again, the user 200 instantly observes the changes to the projected frame 142 moving during this process. The user then presses the trigger to a second position (e.g., fully) to activate the DAD 135. The DAD 135 may be activated to capture an image of the item for post processing or captures and decodes the barcode 320. The data related to the item may then be superimposed onto the display device 120 at a predetermined location (e.g., as a function of the location of the item in the display device 120). As discussed above, the display device 120 is also configured to show data to the user beyond being viewable therethrough. It should be noted that further data may be used in rendering the superimposed image such as location (e.g., generated via 6-dimensional motion sensors or GPS) and orientation data (e.g., generated via sensors such as an accelerometer). When there is a stack of items 305, 315, 325, the user 200 is able to rapidly move the DAD 135 to data capture each of the items with no delay in the visual on the display device 120 and with minimal processor or power consumed.
The exemplary embodiments provide a MU including a transparent display device. The display device enables a user to view therethrough to a location. The user may then perform a data capture functionality as a function of the view through the display device. For example, an aimer may be activated that generates a projected frame. The user may move the MU until the projected frame reaches a desired location. The user may subsequently activate an imager to perform the data capture functionality. During this process, the view through the transparent display device allows for the user to continually see the desired location with no latency on the view of the transparent display device, thereby providing a genuine real-time view. Furthermore, no processing or rendering of images is performed that would otherwise use power or cause greater delay in the view from requiring processing power.
