Abstract:
A method for tap detection and for interacting with a handheld electronic device, and a handheld electronic device configured therefore are described. In accordance with one embodiment, there is provided a method for tap detection on a handheld electronic device, comprising: measuring acceleration using an accelerometer of the handheld electronic device; determining when measured acceleration exceeds an upper limit threshold and a lower limit threshold within a predetermined duration of each other; when the upper limit threshold and lower limit threshold have been exceeded, determining a rate of change of acceleration between the upper limit threshold and lower limit threshold and registering a tap input when the rate of change of acceleration exceeds a predetermined tap threshold.
