Abstract
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.
