Abstract

素手による直接操作機能とテキスト情報の音声出力機能を付加したインタラクティブ型触覚ディスプレイの開発を続けてきており,被験者実験からユーザが自己位置を喪失することが知見として得られた.この問題へのアプローチとして,触覚ディスプレイの複数画面におよぶ大域コンテンツ中での自己位置を通達するデバイス:触覚スクロールバーを提案する.本稿ではその実装と評価について述べる.

A basic device combining a tactile graphic display function and a touch position sensing function is proposed. The trial device consists of two major components, a tactile graphic display and a force sensor. The force sensor measures a center of gravity generated by touch action on the display surface and a PC estimates the point based on the data. The fundamental function for achieving the interactive communication is to detect the location where user is touching a tangible surface. By applying this functions, the click and scroll function by an empty hand are realized. In addition, an audio-tactile graphic system which can be used mainly to overcome tactile cognitive limitation is implemented as an application of the system. Moreover, the area of tactile display is expanded for the purpose of improvement usability. Following this, we propose the tactile scrollbar where the users can recognize their position of plane space. The validity of the developed tactile graphic system has been confirmed through subjective experiments.
