Systems and methods for configuring the display resolution of an electronic device based on distance and user presbyopia

摘要

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.

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, anddetermining 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.
