Systems and methods using computer vision and capacitive sensing for cursor control
First Claim
1. A vision-based navigation control system comprising:
- an input detection component that detects user input;
a monitoring component that receives data from the input detection component which causes the monitoring component to turn on or off; and
a navigational driving component that receives image data from the monitoring component to facilitate determining where to position or drive a cursor.

Abstract
Disclosed is a unique system and method that facilitates cursor control based in part on computer vision activated by a capacitive touch sensor. When turned on, user hand gestures or movements can be tracked by a monitoring component and those movements can be converted in real-time to control or drive cursor movements and/or position on a user interface. The system comprises a monitoring component or camera that can be activated by touch or pressure applied to a capacitive touch sensor. A circuit within the sensor determines when the user is touching a button (e.g., on keyboard or mouse) that activates the monitoring component and cursor control mechanism. Thus, intentional hand movements by the user can readily be determined.
