Abstract
Techniques that can improve efficiency of a touch sensitive device are presented. A touch controller (TC) can comprise a hover classification engine and an application processor (AP) can comprise a touch classification engine usable to classify touch or hover interactions of an object(s) with a touch sensitive surface (TSS) of the device. In response to classifying a touch or hover interaction with TSS as unintentional, AP can reject such interaction and can transition from an active state to an inactive state. TC can continue to monitor touch or hover interactions with TSS. In response to determining there is an intentional touch interaction with TS S or no unintentional face/ear interaction with TSS, TC can transmit a notification signal to AP. In response to the notification signal, AP can transition from the inactive state to active state, and can process the intentional touch interaction or monitor the TSS.
