Study of Analysis of Sighted People Haptic Performance and Efficient Representation of behavior Tactile Graphics

Abstract

Blind people often difficult understand tactile graphics information in braille text, because tactile graphics drawing complicated. In addition, there is little knowledge about touching tactile graphic and an effective teaching touching method has not been established. In related research, we are not conducting experiments in a situation close to the environment normally used by blind people. It is necessary to make quantitative measurements and do not limit the touch and do experiments with the notation method used in braille text. Therefore, in this paper, in order to acquire knowledge about efficient tactile sensation, this time we will investigate the influence on the tactile figure survey using the tactile graphic feature struggling to grasp figure and the tactile observation method, we investigated discrimination threshold of dot pattern used for graphic representation.
