Selective touch scan area and reporting techniques
First Claim
1. An electronic device, comprising:
- a touch screen display for displaying content to a user and having an input detecting area configured to receive user inputs; and
a touch screen controller having a selective touch screen mode configured to selectively scan the touch screen display by scanning for user input from a preselected portion of the input detecting area that is not all of the input detecting area of the touch screen display; and
a user interface configured to present a set of adjustable boundary markers, that once engaged, allows for user-customization of the preselected portion of the input detecting area with respect to size and location of the preselected portion.

Abstract
Techniques are disclosed for selective area scanning, touch scanning, and/or reporting of touch screen contacts in electronic touch sensitive devices. The selective area scanning can be used to only scan a specific section of a touch screen area, the selective touch scanning can be used to scan only for specific touches or input sources on a touch screen, and the selective reporting can be used to selectively report only desired contacts to a device processor and reject all other contacts. Multiple selective scan areas can be provisioned, with each discrete area customizable with respect to location, size, accepted touch types and/or reporting criteria. In some cases the user can configure some or all of these selective screen features.

11. A system, comprising:
-
a processor; a touch screen display for displaying content to a user and having an input detecting area, the touch screen display allowing a plurality of user input gesture types from a plurality of user input sources, and the input detecting area including a preselected portion; a user interface configured to present a set of adjustable boundary markers, such that movement of at least one of the adjustable boundary markers allows for user-customization of the preselected portion of the input detecting area with respect to size and location of the preselected portion; and a touch screen controller having a selective touch screen mode configured to at least one of selectively scan or report a subset of inputs detectable via the touch screen display and that are received within the preselected portion of the display, such that one or more of the inputs detectable via the touch screen display that are received within the preselected portion of the display are not scanned for or reported to the processor. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory computer readable medium encoded with instructions that when executed by one or more processors, cause a process to be carried out in a system having a touch screen display, the touch screen display having an input detecting area and configured for detecting user input, the process comprising:
-
presenting a user interface configured to present a set of adjustable boundary markers, that once engaged, allows for user-customization of a preselected portion of the input detecting area with respect to size and location of the preselected portion, wherein the preselected portion is not all of the input detecting area of the touch screen display; and selectively scanning the touch screen display by scanning for input from the preselected portion of the input detecting area, such that there is a portion of the input detecting area where scanning for input is not performed. - View Dependent Claims (17, 18, 19, 20)
