DISPLAY DEVICES AND METHODS FOR DETECTING USER-INTENDED TOUCH INPUT

摘要

Display devices and methods for detecting user-intended touch input are provided. An example display device includes a touch-sensitive display. Further, the display device includes an impact sensor attached to the touch-sensitive display and configured to generate a signal representative of an impact of the touch-sensitive display. The display device also includes a computing device configured to receive the signal. The computing device is also configured to detect a peak of the signal. Further, the computing device is configured to determine whether a rising edge of a magnitude of the peak detected signal meet predetermined criteria. The computing device is also configured to indicate detection of user-intended touch in response to determining that the predetermined criteria are met.

1. A display device comprising:
a touch-sensitive display; an impact sensor attached to the touch-sensitive display and configured to generate a signal representative of impacts to the touch-sensitive display; and a computing unit configured to:
receive the signal;determine whether a predetermined fraction of the signal is greater than a low-pass filter output of the signal; andindicate detection of user-intended touch in response to determining that the predetermined fraction of the signal is greater than a low-pass filter output of the signal.
