Selective touch scan area and reporting techniques
First Claim
1. An electronic device, 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;
a touch screen controller having a selective touch screen mode configured to selectively scan the touch screen display by scanning for input from a preselected portion of the input detecting area that is not all of the input detecting area of the touch screen display, such that there is a portion of the input detecting area where scanning for input is not performed, and wherein the selective touch screen mode is further configured to selectively report the scanned input from only the preselected portion of the input detecting area to the processor by reporting only a preselected subset of the user input gesture types detected by the touch screen display, such that there is one or more of the user input gesture types that are ignored if detected by the touch screen display, regardless of the user input source; and
a user interface configured to present a set of adjustable boundary markers so as to allow for user-customization of the preselected portion of the input detecting area with respect to size and location, the user interface further configured to simultaneously present the preselected subset of the user input gesture types and one or more applications that are selectable, the selectable user input gesture types including a stylus input, a tap input, and a swipe gesture input, and the one or more applications being executable on the electronic device and selectable to determine for which of those applications the selective touch screen mode is enabled.

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.

9. A system, comprising:
-
a processor; a touch sensitive screen having an input detecting area and configured for detecting input from a plurality of user input sources; a touch screen controller having a selective touch screen mode configured to selectively scan the touch sensitive screen by scanning for only a subset of the user input sources and not for at least one other of the user input sources, such that only input received from the subset of the user input sources is reported to the processor; wherein the selective touch screen mode is further configured to selectively report to the processor only a preselected subset of user input gesture types detected by the touch sensitive screen, such that there is one or more of the user input gesture types that are ignored if detected by the touch sensitive screen, regardless of the user input source, and wherein the selective touch screen mode is further configured to selectively scan for input from a preselected portion of the input detecting area that is not all of the input detecting area of the touch sensitive screen, such that there is a portion of the input detecting area where scanning for input is not performed; and a user interface configured to present a set of adjustable boundary markers so as to allow for user-customization of the preselected portion of the input detecting area with respect to size and location, the user interface further configured to simultaneously present the preselected subset of the user input gesture types and one or more applications that are selectable, the selectable user input gesture types including a stylus input, a tap input, and a swipe gesture input, and the one or more applications being executable on the system and selectable to determine for which of those applications the selective touch screen mode is enabled. - View Dependent Claims (10, 11, 12, 13)

14. 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 input from a plurality of user input sources and for allowing a plurality of user input gesture types, the process comprising:
-
selectively scanning the touch screen display by scanning for input from a preselected portion of the input detecting area that is not all of the input detecting area of the touch screen display, such that there is a portion of the input detecting area where scanning for input is not performed; and selectively reporting the scanned input from only the preselected portion of the input detecting area to a processor by reporting only a preselected subset of the user input gesture types detected on the touch screen display, such that there is one or more of the user input gesture types that are ignored if detected by the touch screen display, regardless of the user input source; and presenting a user interface configured to present a set of adjustable boundary markers so as to allow for user-customization of the preselected portion of the input detecting area with respect to size and location, the user interface further configured to simultaneously present the preselected subset of the user input gesture types and one or more applications that are selectable, the selectable user input gesture types including a stylus input, a tap input, and a swipe gesture input, and the one or more applications being executable on the system and selectable to determine for which of those applications the selective touch screen mode is enabled. - View Dependent Claims (15, 16)
