บทคัดย่อ

Hand gesture-based interaction has great importance role in human-computer interface. However, many applications have been proposed to incorporate with additional wearable sensors and some specific training for each user may be required. These limitations make it inconvenience for using in the real world. This paper presents one-handed gesture based interaction for image zoom manipulation, which is fast and easy to implement. The manipulation of zoom command with natural gesture is to pinch or to stretch fingers, like on touch-devices. Energy feature extracted from hand contour of grasping and spreading fingers represent zoom-in/zoom-out commands, respectively. The relative percentage of hand energy, while manipulating image zoom, and image zoom level is presented. The experimental results show that a speed of zoom manipulation and hand size is invariance to the energy percentage. Therefore any users can easy perform on their natural way to zoom an image without training. ฉ 2015 IEEE.
