1. A method comprising:
- receiving a video of a user interaction with a touch screen;
using a computer vision process to identify a gesture in the video;
detecting a first display update on the touch screen;
determining a response time of the touch screen with respect to the gesture, wherein determining the response time includes counting one or more frames between the gesture and the first display update;
tracking a display area update percentage subsequent to the first display update, wherein the display area update percentage is tracked on a frame-by-frame basis;
conducting a frame rate determination for the touch screen based on the display area percentage update; and
outputting the response time and a result of the frame rate determination.

Abstract
Methods and systems may provide for receiving a video of an interaction with a touch screen, using a computer vision process to identify a gesture in the video, and determining a response time of the touch screen with respect to the gesture. Moreover, a display area update percentage can be tracked subsequent to a response of the touch screen to the gesture, wherein a frame rate determination may be conducted for the touch screen based on the display area update percentage.
