First Claim
Patent Images
1. A machine implemented method comprising:
- receiving signals from a plurality of nodes about a first touch of an array of touch screen sensor nodes;
determining whether the received signals are representative of a finger touch or a stylus touch; and
entering a detect mode as a function of the type of touch determined.

Abstract
A method and device receives signals from a plurality of nodes about a first touch of an array of touch screen sensor nodes. It is determined whether the received signals are representative of a finger touch or a stylus touch. A detect mode may be entered as a function of the type of touch determined.

10. A machine implemented method comprising:
-
scanning nodes in an array of touch screen sensor nodes for normal detections; if a normal detection is encountered, interpret the normal detection as a finger touch; if the touch is below a normal detection touch threshold but above a stylus touch threshold, quantifying nodes surrounding the touch; if the quantification of the surrounding nodes is indicative of a stylus touch, interpreting the touch as a stylus touch; and entering a detect mode as a function of the type of touch interpreted. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system comprising:
-
a touchscreen having a plurality of sensor nodes to provide signals from the plurality of nodes about a first touch of an array of touch screen sensor nodes; a controller communicatively coupled to the touchscreen sensor nodes to receive the signals and determine whether the received signals are representative of a finger touch or a stylus touch, and to enter a detect mode as a function of the type of touch determined. - View Dependent Claims (19, 20)
