Abstract

<p>The aim of our study is to develop a multimodal tactile display for barrierfree access to information for elderly people, people with visual and/or hearing disability, and people with Autistic Spectrum Disorders. In this study, a new multimodal tactile display system is constructed based on sensory evaluation for sense of materials. The tactile display consisted of a pressure sensor, a Peltier device, and a speaker based on the Haptic Map model for representing any tactile sensation by combining of the following three physical stimuli; weight (static parameter), vibration (dynamic parameter), and temperature. An experiment was conducted to evaluate the performance of the proposed display. A total number of eight participants evaluated the haptic sensation generated by the Haptic Map model. Each of the eight participants were instructed to place the third finger on the display; then the various stimuli presented to the third finger. The participants were not informed regarding the tactile stimuli, which were combined by the method. The results indicated that the participants perceived the tactile sensation, such as titillate, sore and itch. For instance, such as combined the static stimuli; 1 kgf/cm2 and the dynamic stimuli; 140 Hz, a volunteer perceived the surface texture and four volunteers perceived the sore for their third finger. In conclusion, the tactile display system is able to present multimodal tactile sensation. </p>
