Android-based system for touch input handling

An Android-based system for touch input handling, comprising:

• an interactive hardware, comprising a display panel and a touch panel that runs a touch firmware;
• and
• an application processor, coupled to the interactive hardware, and running an application program and a touch driver;
• wherein the application processor further converts a hardware synchronization signal of the display panel into a software synchronization signal, and generates an application synchronization signal based on the software synchronization signal;
• wherein expiration of the application synchronization signal triggers a UI thread of the application program to draw one or more image layers in response to a touch event collected by the touch panel;
• wherein the application processor further generates an input synchronization signal that is synchronized with the application synchronization signal;
• and
• wherein expiration of the input synchronization signal triggers the touch firmware to collect the touch event and propagate the touch event up to the application program through the touch driver.
