METHOD AND SYSTEM FOR DISCRIMINATING STYLUS AND TOUCH INTERACTIONS

摘要

Embodiments of the invention are directed to control devices, such as human interface devices, configured for use with a tablet computer. More specifically, the present invention relates to methods and system for discriminating between the interactions of a handheld device, touch of one or more of the user's finger(s) and interaction with appendages of the user on a touch-screen tablet computer. The methods described herein may include discriminating between the interaction of the handheld device, the user's finger(s) and an appendage of the user so that the collected information can be used to control some aspect of the hardware or software running on the touch-screen tablet computer.

1. A method using a touch sensitive computing device, comprising:
receiving, at the computing device, information related to a plurality of touch data points from a touch sensing unit coupled to the computing device; defining a boundary that encloses a region of a surface of the touch sensing unit, wherein the position of the plurality of touch data points on the surface of the touch sensing unit are disposed within the boundary; attributing a first touch data point of the plurality of touch data points to a type of user input by analyzing the position of the first touch data point relative to a portion of the boundary; and generating output data that comprises information relating to the type of user input that is attributed to the first touch data point.
