Abstract
Examples are disclosed relating to computing devices and methods for performing touch detection within a virtual trackpad area of a touch screen display. In one example, a non-trackpad touch input signal is received from outside the virtual trackpad area and processed with at least one touch detection algorithm applying a non-trackpad threshold value. A virtual trackpad touch input signal is determined to be received from within the virtual trackpad area. On condition of determining that the virtual trackpad touch input signal is received from within the virtual trackpad area, the virtual trackpad touch input signal is processed with the touch detection algorithm applying a virtual trackpad threshold value different from the non-trackpad threshold value.
