Effect of Zooming Speed and Pattern on Using IPTV by Zoomable User Interface

Abstract

The users preferred faster movement for the zooming speed. The execution performance of zooming interface affects the actual running time. This study was designed for the movement of robot arm so users expected the movement similar to the actual movement of human. It is considered to be natural that, like human’s movement, the robot arm slowly adjusts its position toward a target after the rapid burst movement in early stage. It is assumed that users expect the movement different from human’s movement for the zooming. Users expect the geometric extension of the object detected through visual organs as the movement by three dimensional approach of the visual object. According to our experiment result, it is shown that users have relatively not bad feeling from Speed 6 to Speed 12 excluding Speed 4 condition which is the lowest speed.
