In this paper, we propose gesture recognition based 3D Serious Games to prevent dementia. These games are designed to enhance the effect of preventing dementia by helping increase brain usage and physical activities of users by the entire body gesture recognition. The existing cameras used for gesture recognition technology are limited in terms of recognition ratio and operation range. For more stable...
This paper proposes a vision-based human-computer interface system that can interpret a user's gestures in real time to manipulate windows and games. The system uses a 3D depth camera to capture depth data up to 30 frames per second. It extracts hand and fingertips from the acquired depth image. It recognizes the movement and click gesture by analyzing the location and shape change of fingertips....
This paper proposes a facial expression recognition system for the laughter therapy. The proposed system takes two steps: face detection and facial expression recognition. At the face detection stage, candidate facial areas are detected in real time from images taken by a camera in consideration of Haar-like features, followed by the application of a SVM(Support Vector Machine) classifier to detect...
This study proposes a real-time lip-reading method in smart phone environment. In smart-phone environment where the resources are limited compared to existing PC environment, it is hard to operate lip-reading in real-time. To solve this problem, this study proposes the lip area detection method and feature extraction method suitable for smart-phone environment. First, to find the accurate lip area,...
