Abstract
As gesture recognition technology has improved, it has been applied to various consumer appliances to provide natural interfaces. Television is a representative system for this kind of interface because of its complex requirements for various functions. Icon-based interfaces are the general method used. However, according to the performed survey, various functions were not required for watching TV. This work found most viewers mainly tend to use some specific functions such as channel or volume. These functions should be controlled easily and quickly since they are frequently used. However, the iconbased interface has difficulty fulfilling this requirement since it is affected by Fitts' law. Hence, this paper proposes a gesturebased method for easy and quick control. User hand gestures are recognized by capturing the motion path when the user draws different symbols in the air. These gestures are used to interact with the TV. It is implemented using a single-camera dedicated hardware system. This system is based on a real time parallel processing structure. The analysis shows that subjects enjoy this TV control system.
