recognition of handwritten characters of Indian script is difficult because of the presence of many complex shaped compound characters (cluster characters) as well as variability involved in the writing style of diffe...
In this paper we present a system towards the recognition of off-line Oriya handwritten characters. Since most of the Oriya characters have curve-like stroke, we use curvature feature for the recognition purpose. To g...

The rate of obese has been increasing and obesity has emerged as a significant threat not only to the health but also in society. Obesity has adverse effects such as physical appearance, psychosocial consequences and metabolic disturbances. One of reasons causing these phenomena is most games have static and stationary user interfaces as input devices. These kinds of interfaces hold users at their computers and cause not only decreases of the strength of their health, but also blocks communications between family members. In this paper, we propose physical activity based interactive exercise called Punch Punch, which is played with virtual objects displaying on a large screen. The informal study revealed that the Punch Punch enhanced physical and social activities while playing games. The goal of this study is finding embodied user interfaces to increase physical and social activities.

We introduce a method of understanding of four musical time patterns and three tempos that are generated by a human conductor of robot orchestra or an operator of computer- based music play system using the hand gesture recognition. We use only a stereo vision camera with no extra special devices. We suggest a simple and reliable vision-based hand gesture recognition with two naive features. One is the motion-direction code which is a quantized code for motion directions. The other is the conducting feature point (CFP) where the point of sudden motion changes. The proposed hand gesture recognition system operates as follows: First, it extracts the human hand region by segmenting the depth information generated by stereo matching of image sequences. Next, it follows the motion of the center of the gravity(COG) of the extracted hand region and generates the gesture features such as CFP and the direction-code. Finally, we obtain the current timing pattern of beat and tempo of the playing music by the proposed hand gesture recognition using either CFP tracking or motion histogram matching. The experimental results on the test data set show that the musical time pattern and tempo recognition rate is over 86.42% for the motion histogram matching, and 79.75% for the CFP tracking.
