First Claim
Patent Images
1. An input device comprising:
- a first sensor configured to detect a contact or a proximity of the device to an object;
a second sensor configured to detect at least one of a motion or an orientation of the device;
a controller configured to determine a condition of the device based on the detected contact or the detected proximity and at least one of the detected motion or the detected orientation of the device; and
a transmitter configured to transmit the determined condition so as to cause an action based thereon.

Abstract
An intelligent stylus is disclosed. The stylus can provide a stylus condition in addition to a touch input. The stylus architecture can include multiple sensors to sense information indicative of the stylus condition, a microcontroller to determine the stylus condition based on the sensed information, and a transmitter to transmit the determined condition to a corresponding touch sensitive device so as to cause some action based on the condition.
