Abstract
A touch panel system comprising a single-point detection panel, responsive to a touch action, for outputting a signal; and a processor for processing the signal to determine a location on said single-point detection panel on which said touch action is manipulated; wherein the processor, based on an algorithm, within a predetermined time interval, detects the variation of said location to judge whether the touch action on the panel is a single-point touch or multiple-point touch.
Claims22
A touch panel system, comprising:
- a single-point detection panel outputting a signal responsive to a touch action;
- and
- a processor processing the signal for judging a location of the single-point detection panel on which the touch action is performed;
- wherein the processor, based on an algorithm, detects a variation of the location within a predetermined time interval, to judge whether the touch action is a single-point touch or a multiple-point touch.
A method for detecting a single-point touch or a multiple-point touch based on a single-point detection panel, the single-point detection panel outputting a signal responsive to a touch action, the method comprising:
- processing the signal to determine a location of the single-point detection panel on which the touch action is performed;
- and
- detecting a variation of the location within a predetermined time interval, based on an algorithm, to judge whether the touch action is a single-point touch or a multiple-point touch.
