DEVICE AND METHOD FOR DETECTING TOUCH DELAY TIME
First Claim
1. A device for measuring a touch delay time of a touch screen panel, the device comprising:
- an event driver configured to i) receive an interrupt signal generated by a touch on a touch screen panel, ii) process a first system count value at a time when the interrupt signal is received as an interrupt generation time, and iii) schedule a task corresponding to the interrupt signal; and
a delay time measurement module configured to i) process a second system count value at a time when a task execution signal is transmitted to an application module as an application execution time, and ii) calculate the touch delay time based on the difference between the interrupt generation time and the application execution time.

Abstract
A device and method for detecting touch delay time are disclosed. In one aspect, the device includes an event driver and a delay time measurement module. The event driver is configured to receive an interrupt signal generated by a touch on a touch screen panel, process a first system count value at a time when the interrupt signal is received as an interrupt generation time, and schedule a task corresponding to the interrupt signal. The delay time measurement module is configured to process a second system count value at a time when a task execution signal is transmitted to an application module as an application execution time, and calculate the touch delay time based on the difference between the interrupt generation time and the application execution time.

15. A method for measuring a touch delay time, the method comprising:
-
generating a hardware interrupt that corresponds to a touch on a touch screen panel; receiving an event code that corresponds to the hardware interrupt; receiving an event function, when the event code is received, for executing a task that corresponds to the hardware interrupt; executing an application for performing the task when the event function is received; and calculating, at a computing device, the touch delay time from the generating to the executing. - View Dependent Claims (16, 17, 18, 19, 20)
