ELECTRONIC DEVICE AND METHOD FOR CHANGING DATA DISPLAY SIZE OF DATA ON DISPLAY DEVICE

摘要

A method for changing data display size using an electronic device includes storing a standard ratio of a height and a width of an eye area of a user when his eyes are open normally. A facial image of the user is taken using an image capturing device at each predetermined time interval, and a ratio of a height and a width of an eye area is calculated based on the facial image. An application program which has data being currently displayed on the display device is determined. When the calculated ratio is less than the standard ratio, a first control command is sent to the determined application program to zoom in the data currently displayed on the display device. When an updated calculated ratio is greater than or equal to the standard ratio, the determined application program stops zooming in the data.

主权项

1. A computer-implemented method for changing data display size using an electronic device, the electronic device comprising a display device, an image capturing device and a storage device, the method comprising:
storing a standard ratio of a height and a width of an eye area when eyes of a user are open normally; acquiring a facial image of the user at each predetermined time interval using the image capturing device; calculating a ratio of a height and a width of an eye area recognized from the facial image; determining an application program which has data being currently displayed on the display device; sending a first control command to the determined application program and controlling the determined application program to zoom in the data currently displayed on the display device according to the first control command, under the condition that the calculated ratio is less than the standard ratio; and sending a stop command to the determined application program to stop zooming in the data currently displayed on the display device, when an updated calculated ratio is greater than or equal to the standard ratio.
