Abstract
This paper describes about a robot system for finding and using character strings in daily environment. The system is mainly composed of a method that finds character candidates by taking particular note of closed contour in an image. In the case of low resolution images, some disadvantageous condition occurs, for instance, only a part of actual contour may be able to be found or two closed edges are merged between two characters. To cope with such difficulties, a camera system with gaze adjustment function is used. Character strings can be found by using these functions. Applications to daily assistance are also introduced.
