1. A touchscreen system for accepting multiple touch events and determining tie events, comprising:
- a touchscreen comprising a touch surface for receiving touch events, each of the touch events occurring at a discrete location on the touch surface defined by coordinates;
a touchscreen controller for monitoring the touch surface for the touch events; and
a microprocessor for comparing the touch events, the microprocessor determining a tie occurrence when the touch events occur within a predetermined time of one another.

Abstract
Method and apparatus for detecting multiple touch events on a touchscreen system and determining the occurrence of tie events. The system comprises a touchscreen, a touchscreen controller and a microprocessor. The touchscreen comprises a touch surface for receiving touch events. Each of the touch events occurs at a discrete location on the touch surface defined by coordinates. The touchscreen controller monitors the touch surface for the touch events. The microprocessor compares the touch events and determines a tie occurrence when the touch events occur within a predetermined time of one another.

9. A method for determining a tie event occurring on a touchscreen system accepting multiple touches, comprising:
-
monitoring a touchscreen for touch events, each touch event occurring at a discrete location on the touchscreen defined by a coordinate system;
comparing first and second touch events to determine a relative timing between the first and second touch events; and
determining that a tie event has occurred when the relative timing is within a predetermined time. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for reporting a tie event occurring on a touchscreen system accepting multiple inputs, comprising:
-
monitoring a touchscreen for touch events, each touch event occurring at a discrete location;
detecting a first touch event having a first timing event;
detecting a second touch event having a second timing event;
comparing a difference between the first and second timing events to a predetermined time; and
setting a flag identifying a tie occurrence when the difference is within the predetermined time. - View Dependent Claims (17, 18, 19, 20)
