A "double-touch" input method is described that is particularly suitable for use as a substitute for a "double-click" input from a mouse or trackball, and that is particularly suitable for use with a touch panel. Briefly, the input method involves contacting a touch panel at a first location (for example, over an area where an icon is displayed) with a first finger. Before a predetermined period of time T.sub.wait elapses, a second finger "taps" the panel at a second location. The location tapped by the second finger is greater than a predetermined distance from the first location tapped by the first finger. In addition, the tap by the second finger is shorter than a second predetermined period of time T.sub.tap. After the tap by the second finger, the first finger is still in contact with the touch panel. The position of the first finger after the tap should be within a predetermined range of its position just prior to the tap. Apparatus in the form of a device driver is described for detecting a double touch input.
An input detection apparatus for use with a touch panel that outputs coordinate data indicative of the location on the panel touched by an object;
A computer system for use with a double touch input method wherein a first finger contacts the touch panel at a first location, and remains in contact with the touch panel while a second finger momentarily contacts the touch panel at a second location, said computer system comprising:
