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 including a user interface coupled to a touch sensing unit capable of detecting input received on the user interface, the method comprising:
receiving, at the computing device, information related to a plurality of touch data points that are detected on the user interface at a first time; determining a first cluster of the plurality of touch data points is associated with a touch from a user's appendage; defining a boundary on the user interface around the first cluster; attributing a first touch data point of the plurality of touch data points to a handheld device upon determining that the first touch data point is located within the boundary; and generating output data that comprises a label attributing the first touch data point to the handheld device.
