Abstract (in Japanese) (See Japanese page) 
(in English) We propose a new method of presenting two-dimensional information on a tactile display so that visually impaired people are able to perceive easier them. The new presentation method is developed for a tactile-proprioceptive display, which can present information on not only conventional ‘‘concave–convex’’ tactile display, but also mechanical leading presentation by mechanically leading user’s fingers using haptic device. In this paper, we evaluated the effects for cognitive map formation of the tactile-proprioceptive presentation method in comparison with the conventional voice guide or “concave–convex” presentation method. In the experiment, after memorizing a landmark position and the route in the simulated map, the subject drew them on the tactile display by the recall method. The evaluation of the effect was performed by with an objectivity evaluation by the drawing time and a correct answer score for recalled route , the number of the correct answers of the landmark position, and with a subjectivity evaluation by the easiness of image and memory. The evaluation result shows that the evaluation values of the tactile-proprioceptive presentation method is statistically higher than the voice guide, and is tendency higher than the “concave–convex” presentation method. These results suggest the possibility that the proposed tactile-proprioceptive presentation method is effective for the formation of the cognitive map, and is available as means to learn a map before walking.
