¿µ¹®³»¿ë¿ä¾à The standard introduces criteria for UX quality measurement of which quantitative definition and measuring methods are not yet clearly established. UX quality differs by response time after user input, and the movement of frame. In the standard, initial response time and response ending time will be measured to define response time. To define movement, frame rate, frame rate uniformity, and jerk will be measured. Also, the standard introduces analysis techniques of measurement from user perspective, and their cognitive and physical background.
