Abstract:The evolution of Android smartphone has increased the importance of touchscreen capabilities as user interaction as well as user input method. However, due to the limitation of Android architecture, every touch event may not create its corresponding display update all the times. To overcome this limitation, this paper proposes a novel technique of Touch Event Handling Block (TEHB) with capability of virtual touch event generation and low pass filters. TEHB is implemented on Android 2.2 and its performance simulations show that TEHB can achieve more performance gain than conventional triggering method.
