Tactile and Haptic Presentation Technology of 2&3-dimensional Information

Outline
We are studying technology that allows two-dimensional information (e.g., maps) and three-dimensional information (e.g., works of art) to be conveyed to visually impaired people by tactile and haptic means. This exhibit shows a tactile display that allows people to grasp the layout or salient features of a picture by touch alone, and a haptic presentation device that allows users to touch a virtual object that feels similar to a real object.

Features

●A tactile display that uses various vibration modes to represent an arbitrary area
By presenting the constituent elements of a picture with diverse vibration modes that combine different frequencies and vibration time intervals, it is possible to grasp by touch alone the categories of items in a menu, or positional information such as earthquake and tsunami information, or the important parts of a map or graph. This makes it possible to support the rapid transmission and understanding of information similar to that normally obtained visually.
●Haptic presentation device with five stimulus points on a finger pad
Shape features are conveyed by five stimulus points where the finger touches the virtual object. Users can feel features such as vertices and contours that are difficult to feel with a single stimulus point. This makes it easier to recognize the shape of a virtual object.

In the works

In our ongoing research, we are evaluating the cognitive characteristics of information gathered by tactile and haptic means, and we aim to implement a television service that allows viewers to touch objects such as images delivered by data broadcasting and virtual works of art.

  • ●Part of this research is being conducted in collaboration with the University of Tokyo.
