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. En some cases the user can configure some or all of these selective screen features.
