This report presents a brief outline of the GATE (= Graphics Accessible to Everyone) project architecture and an analysis of some problems and approaches connected to the detection and annotation of graphical objects in raster images. It also mentions some experiments concerning the object detection and annotation. Some examples and illustrations are presented as well.

The architecture of the blind user oriented hypertext AUDIS developed at the Faculty of Informatics, Masaryk University Brno, is described in the paper. AUDIS is developed primarily as a support, which would help visually impaired students to study various materials. It can also serve as an Internet browser.

Orientation is one of the most important problems of visually impaired people. The aim of this paper is to suggest a contribution to the solution of this problem using computer technology. The basic idea is the detection of motion and orientation using sensors and consequent position identification. The detected trajectory is compared with a map and is corrected by means of the algorithm described in the paper. Some problems concerning sensor detection of human motion are also discussed. Based on the determined position other relevant information is provided to the user of system (information describing the neighbourhood of the actual position, optimal way to the chosen destination, possible warnings).
