Abstract:
A method for recognizing a gesture made on a touch-sensor pad in a touch-sensing system providing X and Y position information to a host, comprising:detecting a first presence of a conductive object on the touch-sensor pad; comparing the duration of said first presence with a first reference amount of time; initiating a first gesture signal to the host if the duration of said first presence is less than said first reference amount of time; detecting a second presence of said conductive object on the touch-sensor pad; comparing the duration between said first presence and said second presence with a second reference amount of time; comparing the duration of said second presence with a third reference amount of time; terminating said first gesture signal if the duration between said first presence and said second presence is greater than said second reference amount of time; and maintaining said first gesture signal and repeatedly sending X and Y position information to said host until the occurrence of a terminating event if the amount of time between said first presence and said second presence is less than said second reference amount of time and if the duration of said second presence is greater than said third reference amount of time.
