SYSTEM AND METHOD FOR LOW POWER INPUT OBJECT DETECTION AND INTERACTION
First Claim
1. A method of operating a touch screen, said method comprising:
- detecting an object interaction with said touch screen while in a first doze mode;
determining if a detected object interaction with said touch screen is a valid input object interaction with said touch screen; and
in response to determining said object interaction is a valid input object interaction;
transitioning from said first doze mode to a gesture recognition mode; and
transitioning from said gesture recognition mode to an active mode in response to a determination of a valid gesture interaction by said object with said touch screen.

Abstract
In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.

11. A touch screen processing system for an electronic system, said touch screen processing system comprising:
-
sensor circuitry configured to detect object interaction in a sensing region of said touch screen; display update circuitry configured to update a display associated with said touch screen; and a control logic configured to; detect at periodic intervals for an object interaction with said touch screen while in a first doze mode, wherein said first doze mode comprises a host processor of said electronic system being in a low power state and operations associated with said touch screen being processed by said touch screen processing system; and a determination module configured to; determine if a detected object interaction with said touch screen is a valid input object interaction with said touch screen; in response to a determination that said object interaction is a valid input object interaction; transition from said first doze mode to a gesture recognition mode; and transition from said gesture recognition mode to an active mode in response to a determination of a first type of valid gesture interaction with said touch screen by said object, wherein said active mode comprises said host processor departing said low power state; and in response to a determination of a second type of valid gesture interaction with said touch screen; update said display while said host processor remains in said low power state. - View Dependent Claims (12)
