USER-TRACKABLE MOVING IMAGE FOR CONTROL OF ELECTRONIC DEVICE WITH TOUCH-SENSITIVE DISPLAY

摘要

The present disclosure provides an electronic device and a method of operation thereof, in which accidental, careless or unintended user input is mitigated. A sequence of frames is displayed on a touch-sensitive display of the electronic device to depict an image moving in an image path over a time interval. A user touch path, generated in response to the moving image, is sensed over the time interval. The image path is compared with the user touch path to determine a path tracking accuracy and the electronic device is controlled responsive to the determined path tracking accuracy. In this manner, unlocking an electronic device and selection of a device function may be achieved by a single user action.

主权项

1. An electronic device, comprising:
a touch-sensitive display; a processor coupled to the touch-sensitive display; and a memory coupled to and in cooperative arrangement with the processor, the processor and memory configured to:
display a sequence of frames on the touch-sensitive display that depict an image moving in image path over a time interval;receive data representative of a user touch path over the time interval in response to user contact with the touch-sensitive display;compare the user touch path with the image path to determine a path tracking accuracy of the user touch path relative to the image path; andcontrol operation of the electronic device responsive to the path tracking accuracy.
