[0028] Referring now to the drawings, and more particularly to Figures 1 through 9, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
[0029] Referring to Figure 1, the electronic device 100 is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the electronic device 100 may comprise at least one input/output (I/O) interface 102 (herein a configurable user interface), a processor 104, a memory 106, a camera 108 (or a scanner) and a liquid lens 110 integrated on a display of the electronic device 100. The at least one processor 104 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the at least one processor 104 is configured to fetch and execute computer-readable instructions stored in the memory 106.
[0030] The I/O interface 102 may include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface, and the like. Further, the I/O interface 102 may enable the electronic device 100 to communicate with or accessed by other computing devices, such as web servers and external data servers (not shown). The I/O interface 102 may facilitate multiple communications within a wide variety of networks and protocol types, including wired networks, for example, LAN, cable, etc., and wireless networks, such as WLAN, cellular, or satellite. The I/O interface 102 may include one or more ports for connecting a number of devices to one another or to another server.
[0031] Referring to Figure 2, modules 202 of the electronic device are illustrated. The modules 202 include routines, programs, objects, components, data structures, etc., which perform particular tasks, functions or implement particular abstract data types. In one implementation, the modules 202 may include a calculation module 204 and a modification module 206. The modules 202 may include programs or coded instructions that supplement applications and functions of the electronic device 100.
[0032] The data 208, amongst other things, serves as a repository for storing data processed, received, and generated by one or more of the modules 202. The data 206 may also include a database 208, and other data 210. The other data 210 may include data generated as a result of the execution of one or more modules 202.
[0033] In accordance with an embodiment, referring to Figure 3a, a refraction of light by the liquid lens (herein referred as liquid lens layer) is shown. The liquid lens layer is integrated between the display 302 and protective layer 304 as shown. Figure 3 b shows a back layer of liquid lens layer and a front layer of liquid lens layer that provides a refraction of light passing through the liquid lens and modifies a display of data on the display layer 302 as viewed by a human eye.
[0034] Referring back to Figure 2, 3a and 3b in combination, the user interface 102 (or the configurable user interface) of the electronic device 100 may receive input parameters corresponding to a visibility defect (vision impairment) of the user. The user interface 102 may be pre-configured wherein the user may select values from a predefined list of values corresponding to the visibility defect of the user. The input parameters may be then converted into a voltage difference value and may be applied to the liquid lens 110 so that the light may be refracted and accordingly the display of the data to the user may be modified. This modification in the display of data to the user, avoids a need to wear external glasses for a purpose of clarity while viewing data on the electronic device. The light refracted by the liquid lens due to change in curvature of the liquid lens, helps to adjust refraction of light as per an optical power of user’s eye.
[0035] The voltage difference may be supplied through the back layer 306 and front layer 308 of the liquid lens as shown in Figure 3b.
[0036] In an example, if the user suffering from a myopia (nearsightedness), the user may select a power of -3.2 D in for his left eye and -2 D for his right eye. In an alternate embodiment, the electronic device 100 comprising at least one of the camera 108 and the retina scanner may be used for scanning the eyes of the user in order to detect the visibility detect. Based on detection of the visibility defect scanned by the at least one of the camera 108 and the retina scanner, the visibility defect may be accepted as the input parameter by the user interface 106.
[0037] In case of the retina scanner, the user is shown a sample text on the display integrated to the liquid lens. Initial refraction is calculated based on an optical power (visibility defect) as detected from the retina scanner.
[0038] The calculation module 204 is configured to use the input parameters corresponding to visibility defect (vision impairment) for calculating a voltage value to be supplied to the liquid lens. The input parameters provides optical power for at least one of a human left eye and a human right eye. The optical power is used for calculating the voltage value by the calculation module. Below are described the calculation details performed by the calculation module 204:
Let PRE: optical power of human right eye
PLE: optical power of human left eye
PLL: Average adjusted power of liquid lens integrated over display
a: Mathematical constant depending on property of liquid lens
Padj: Power adjustment
PLL: a × ( PRE + PLE) + Padj Equation (1)
VLL: Voltage applied on liquid lens to get desired optical power integrated over display
ß: Mathematical constant depending on liquid lens and hardware
VLL = ß x PLL Equation (2)
[0039] PRE and PLE may be obtained from a retina scanner attached to the electronic device. The PRE and PLE may also be provided by the user manually.
[0040] The calculation module 204 is configured to calculate the average optical power of the liquid lens by using equation 1, with Padj as optional for achieving fine tuning for better clarity to the user.
[0041] VLL which is calculated in equation 2 is the voltage which needs to be provided to the liquid lens. After the VLL is provided to the liquid lens, the modification module generate the refraction for desired optical power, i.e. PLL.
[0042] The modification module 206 is configured for modifying a refraction of light through the display of the electronic device by using the liquid lens with respect to the input parameters. The modification in the refraction of light modifies a display of the visual data to the user, over the electronic device 100 to avoid a need of wearing external vision aiding glasses by the user.
[0043] The modification by the modification module 206 in the display comprises at least one of a focus of the visual data according to the vision requirements received as the input parameters, a blurring of the visual data according to the input parameter.
[0044] In accordance with an embodiment, Figure 4a shows the refraction of the light through the liquid lens 110. Figure 4b shows the modification of liquid lens 110 as convex lens 402 and concave lens 404 when voltage difference is applied. The liquid remains a plane lens 406 when no voltage difference is applied.
[0045] In an example, the liquid lens may work as concave lens of 3.5 D after applying 32 V of voltage. Similarly a voltage of -32 V may convert the liquid lens into convex lens of 3.5 D optical power as the voltage changes the curvature of the liquid lens.
[0046] The modification is performed by the modification module 206 based on the VLL (voltage difference) as calculated above.
[0047] In another embodiment, referring to Figure 5, the user may tune the refraction of the liquid lens the display layer 302 of the data over the display of the electronic device 100 is set in accordance with the visibility requirement of the user. The tuning may be enabled by providing a range of optical powers pre-stored in the memory 106 of the electronic device 100. From the pre-stored optical powers in the memory 106, the user may set by a desired optical power as per the user’s visibility defect by tuning the refraction based on setting (which provide a selection) of the desired optical power used to calculate the voltage difference to modify the refraction.
[0048] In another embodiment, the visibility defect manually provided by the user or scanned by the camera 108 may be stored in the memory 106 for a future reference by the user.
[0049] In accordance with another embodiment, the electronic device 100 also provides a 3-dimensional display of data by using the liquid lens 110.
[0050] Modification module 204 is further configured to adjust liquid lens power over the display layer 302 to create the 3d effect over the display layer 302. Figure 6a shows that the liquid lens 110 allows the light to diverge to make objects (data) nearer. Figure 6b shows that the liquid lens 110 converges the light to make objects (data) look farther to the user viewing the data over the display layer 302 of the electronic device 100.
[0051] In an example, to provide a 3d display of data, 2 dimensional (2D) of the liquid lens 110 is used for 3d display of the objects. While recording a stream of data (say a movie), depth may be recorded similar to recording to RGB values. The recording of the depth is performed to record a depth (third dimension) information for each pixel or cluster of pixels in the stream of data.
[0052] In order to display the stream of data (movie) with 3d effect, the depth of each of the pixel or the cluster of pixels may be given to the calculation module 202 as an input in formulae described below:
PLL = a × (PRE + PLE) + Padj …… Equation 3
Padj : depth of each pixel or the cluster of pixels
[0053] Voltage difference is calculated by using equation 2 as discussed above. Figure 7 illustrates shows an external voltage source surrounding the liquid lens 110 as an additional hardware. The voltage source may be same as used to provide power to LED screen of the electronic device 100.
[0054] PLL may also be used for adjusting the position of various objects in 3D images or implementing additional privacy by means of encryption.
[0055] The modification module 204 uses the PLL (optical power adjusting value) to converge and diverge the light through the liquid lens 110 to provide a depth perception to the user.
[0056] In accordance with an embodiment, referring to Figure 8, a method 800 for improving display of visual data over an electronic device is described. In an embodiment, the method 800 may be performed within the electronic device 100.
[0057] At step 802, the method 800 provides an integration of the liquid lens 110 over a display of the electronic device 100.
[0058] At step 804, the method 800 provides a customization the user interface 102 of the electronic device 100 to receive input parameters corresponding to vision data of a user.
[0059] At step 806, the method 800 provides modification of a refraction of light through the display layer 302 of the electronic device 100 by using the liquid lens 110 with respect to the input parameters. The modification in the refraction of light modifies a display of the visual data to the user, over the electronic device 100
[0060] In an example embodiment, the display of the data over the electronic device 100 may be modified for a purpose of data security. First entity may select input parameters corresponding to the vision of the data. The input parameters are selected such that the data may be displayed blur to a second entity. As per the selection of the input parameters, the voltage difference is supplied to the liquid lens 110 to modify the refraction of light further modifying the display of the data to the user (in this case blur). The first entity may share tuning details as password with the second entity in order to allow the second entity to alter the display of the data.
[0061] In another embodiment, the method 800 may further provide a three dimensional display of data over the electronic device 100.
[0062] At step 902, the method 800 provides a recording a depth information while recording data for each pixel in the data;
[0063] At step 904, the method 800 provides calculating an optical power adjusting value by using the depth information.
[0064] At step 906, the method 800 provides enabling at least one of a conversion of light and diversion of light based on the optical power adjusting value, wherein the at least one of the conversion of the light and the diversion of the light provides a three dimension display of the data over the electronic device.
[0065] The various actions, acts, blocks, steps, and the like in method 800 may be performed in the order presented, in a different order or simultaneously. Further, in some embodiments, some actions, acts, blocks, steps, and the like may be omitted, added, modified, skipped, and the like without departing from the scope of the invention.
