Systems and methods for configuring the display magnification of an electronic device based on distance and user presbyopia
First Claim
1. A method, comprising:
- determining, in response to identifying that an electronic device has moved according to a series of movements in a z-axis direction comprising at least one forwards movement and at least one backwards movement, that a user of the electronic device is having difficulty visually focusing on at least one feature displayed on the electronic device;
responsive to determining that the user is having difficulty visually focusing on the at least one feature, determining a desired increased magnification factor for increasing magnification of the at least one feature displayed on the electronic device; and
outputting, for transmission to a server, a request indicating the desired increased magnification factor, wherein the server is capable of supplying at least one of a magnified image and magnified text according to the desired increased magnification factor and wherein determining that the user of the electronic device is having difficulty focusing on the at least one feature is not dependent on the state of the face of the user when the electronic device moves according to the series of movements.

Abstract
Systems and methods dynamically configure a display (104) of an electronic device (102) 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 (100) and the display is measured (1002), and the desired display resolution is determined (1006) based on the distance. If a user is exhibiting (1008, 1010) symptoms of presbyopia, a magnification factor may be determined (1012). A request indicating the desired display resolution and/or magnification factor is transmitted (1016) to a server that supplies images, such as pictures or videos. The image is received (1018) from the server and displayed (1020) on the display. A focus area distance and/or a pupil orientation of the user may also influence the desired display resolution. Bandwidth, processing, and power savings may result through the use of these systems and methods.

9. An electronic device, comprising:
-
one or more processors; and a memory coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the electronic device to; determine, in response to identifying that the electronic device has moved according to a series of movements in a z-axis direction comprising at least one forwards movement and at least one backwards movement, that a user of the electronic device is having difficulty visually focusing on at least one feature displayed on the electronic device; responsive to determining that the user is having difficulty visually focusing on the at least one feature, determine a desired increased magnification factor for increasing magnification of the at least one feature displayed on the electronic device, and output, for transmission to a server, a request indicating the desired increased magnification factor, wherein the server is capable of supplying at least one of a magnified image and magnified text according to the desired increased magnification factor and wherein determining that the user of the electronic device is having difficulty focusing on the at least one feature is not dependent on the state of the face of the user when the electronic device moves according to the series of movements. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
