1. A computing system comprising:
- a housing having a notebook form factor;
a touch panel having a touch sensor, a touch panel controller and firmware with a stored set of controller instructions which, if executed by the touch panel controller, cause the touch panel controller to,receive touch panel raw data from the touch sensor, andidentify data of interest in the raw data;
a host processor; and
a machine readable medium comprising a stored set of processor instructions which, if executed by the host processor, cause the host processor to,detect an event based on the data of interest and a touch processing policy, wherein the touch processing policy includes at least one of a debounce component, a finger detection component, a hand rest detection component, a blob detection component, a specific hand shape detection component and a sub-hand shape detection component, andforward the event to at least one of an operating system navigation process and an on-screen keyboard application process.

Abstract
A system and method provide for receiving touch panel raw data and identifying data of interest in the raw data. One or more events may be detected based on the data of interest and a touch processing policy. In one example, the receiving and the identifying are conducted by a touch panel controller, and the detecting is conducted by a host processor. Other techniques, such as subsurface scanning and hybrid scanning may also be used.
