Abstract

Systems and methods dynamically configure a display of an electronic device to a desired display resolution and/or a magnification factor without noticeable impact on the user viewing experience. According to certain aspects, the distance between a user and the display is measured, and the desired display resolution is determined based on the distance. If a user is exhibiting symptoms of presbyopia, a magnification factor may be determined. A request indicating the desired display resolution and/or magnification factor is transmitted to a server that supplies images, such as pictures or videos. The image is received from the server and displayed on the display. A focus area distance and/or a pupil orientation of the user may also influence the desired display resolution.

First claim

The invention claimed is:

1. A method of configuring a display of an electronic device, wherein the display is capable of supporting a plurality of display resolutions, the method comprising:
measuring a distance between the display and a user of the electronic device;
determining, using a processor, a desired display resolution of the display based on the distance, wherein the desired display resolution is one of the plurality of display resolutions;
determining, using the processor, that the user is exhibiting symptoms of presbyopia, by:
identifying a series of movements of the electronic device in a z-axis direction, the series of movements comprising a forwards movement of the electronic device and a backwards movement of the electronic device, and
determining that a frequency of the series of movements exceeds a predetermined threshold frequency;

determining a desired magnification factor, based on the determining that the user is exhibiting symptoms of presbyopia, after determining that the series of movements is complete; and
transmitting a request from the processor to a server external to the electronic device, the request indicating the desired magnification factor, wherein the server is capable of supplying an image according to the desired magnification factor.

2. The method of claim 1 , further comprising:
comparing the distance to a minimum distance threshold, using the processor; and determining the desired magnification factor, if the distance is less than the minimum distance threshold.

3. The method of claim 1 , wherein determining whether the user is exhibiting symptoms of presbyopia comprises:
recognizing squinting of an eye of the user, using a camera of the electronic device and the processor.

4. The method of claim 1 , wherein determining whether the user is exhibiting symptoms of presbyopia comprises:
determining that the user normally wears multifocal glasses; and
recognizing that the multifocal glasses are not being worn by the user, using a camera of the electronic device and the processor, if it is determined that the user normally wears the multifocal glasses.

5. The method of claim 1 , wherein identifying the series of movements comprises:
detecting a change in the distance; and
identifying the series of movements, if the change in the distance exceeds a predetermined back and forth distance threshold.

6. The method of claim 1 , wherein:
determining whether the user is exhibiting symptoms of presbyopia comprises:
receiving a level of presbyopia of the user at the processor; and

determining the desired magnification factor comprises:
determining the desired magnification factor based on the level of presbyopia.

7. The method of claim 1 , wherein transmitting the request comprises:
transmitting the request including a specific format of the image, from the processor to the server, wherein the specific format is based on one or more of: the desired display resolution or the desired magnification factor.

8. The method of claim 1 , wherein measuring the distance between the display and the user comprises:
measuring the distance between the display and the user on a periodic basis.

9. The method of claim 1 , further comprising:
receiving the image as part of a video, from the server at the processor, at one or more of: the desired display resolution or the desired magnification factor; and
displaying the image on the display, using the processor, when a scene changes in the video.

10. The method of claim 1 , further comprising:
receiving the image at the desired display resolution from the server at the processor;
modifying the image based on the desired magnification factor to produce a magnified image, using the processor; and
displaying the magnified image on the display, using the processor.

11. The method of claim 1 , further comprising:
receiving the image at a different display resolution from the server at the processor, wherein the different display resolution is based on the request;
modifying the image based on the desired magnification factor to produce a magnified image, using the processor; and
displaying the magnified image on the display, using the processor.

12. An electronic device, comprising:
a display capable of supporting a plurality of display resolutions;
a distance measurement component for measuring a distance between the display and a user of the electronic device;
a presbyopia detection component for determining presbyopia data associated with the user, the presbyopia detection component configured to transmit the presbyopia data;
a transceiver; and
a processor coupled to the display, the distance measurement component, the presbyopia detection component, and the transceiver, the processor configured to perform operations comprising:
receiving the distance from the distance measurement component;
determining a desired display resolution of the display based on the distance, wherein the desired display resolution is one of the plurality of display resolutions;
receiving the presbyopia data from the presbyopia detection component;
determining that the user is exhibiting symptoms of presbyopia, by:
identifying a series of movements of the electronic device in a z-axis direction, the series of movements comprising a forwards movement of the electronic device and a backwards movement of the electronic device, and
determining that a frequency of the series of movements exceeds a predetermined threshold frequency;

determining a desired magnification factor based on the presbyopia data, based on the determining that the user is exhibiting symptoms of presbyopia, after determining that the series of movements is complete; and
transmitting a request to a server external to the electronic device, the request indicating the desired magnification factor, wherein the server is capable of supplying an image according to the desired magnification factor.

13. The electronic device of claim 12 , wherein the distance measurement component comprises one or more of:
a proximity sensor; or
a camera.

14. The electronic device of claim 12 , wherein the processor is further configured to perform operations comprising:
comparing the distance to a minimum distance threshold; and
determining the desired magnification factor, if the distance is less than the minimum distance threshold.

15. The electronic device of claim 12 , further comprising:
a camera of the electronic device for capturing images including eyes of the user; and
a facial recognition component coupled to the processor and the camera, the facial recognition component for recognizing a squinting of an eye of the user, wherein the camera is configured for capturing images including eyes of the user;
wherein the processor is configured to perform the determining of whether the user is exhibiting symptoms of presbyopia comprising:
determining that the user is exhibiting symptoms of presbyopia, if the facial recognition component recognizes the squinting of the eyes of the user.

16. The electronic device of claim 12 , further comprising:
a camera of the electronic device for capturing images including multifocal glasses worn by the user;
a facial recognition component coupled to the processor and the camera, the facial recognition component for recognizing whether the multifocal glasses are being worn by the user; and
a memory coupled to the facial recognition component and the processor, the memory for storing whether the user normally wears the multifocal glasses;
wherein the processor is configured to perform the deter
