Design of a vision substitution vibrotactile vest for the visually impaired
SETN '18: Proceedings of the 10th Hellenic Conference on Artificial IntelligenceArticle No.: 52, Pages 1–2https://doi.org/10.1145/3200947.3201055In this paper, we create a low-cost, discrete, vibrotactile vest to address the error-prone task of navigation for the visually impaired. Our implementation is based upon sensory substitution principle, which dictates that information captured by a ...

Toward Touching a Landscape in a Picture: Investigation of Groping Strategy about Tactile Images and Image Simplification Method
ICCHP '08: Proceedings of the 11th international conference on Computers Helping People with Special NeedsPages 859–864https://doi.org/10.1007/978-3-540-70540-6_127In this paper, we propose a method for "touching a landscape in a photograph." In concrete terms, it is an image processing to simplify images and making images tactile by a stereo copying machine. How much we simplify images depends on subject's ...

Efficient edge detection from tactile data
A real-time tactile image processing algorithm for edge contact is presented in this paper. Based on basic elasticity results, closed-form solutions for calculating contact force and local contact geometries (i.e., location and orientation of the line ...
