    In this paper we propose a new algorithm to rearrange handwriting for Thai online handwriting beautification. First, we segment the line into the right group (Line of tone level, Line of upper level, Line of body level and Line of lower level). Then we calculate the center point of each character by x average and y average value. After that we find the moving path that includes two perpendicular marks at the end of the path. Finally, we adjust Thai handwriting by moving the character up or down along the Moving line. The text's position is changed into the middle point of the Moving line.

    In this paper we develop hand gesture commands for a Pan-tilt zoom camera. Our proposed scheme creates commands based on hand position and orientation which are captured by a motion sensor (Kinect). The new algorithm supports a rectangular area. In the calibration process, we focus on four interesting points and record two sets of four coordinates from both cameras. The relationship between two sets of values are mapped and applied to control the pan-tilt zoom movement. The results show that a PTZ camera can detect hand gestures and track objects correctly.
