Kana-input navigation system for kids based on the cyber assistant

In Japan, it has increased the opportunity for young children to experience the personal computer in elementary schools. However, in order to use computer, many domestic barriers have confronted young children (kids) because they cannot read Kanji characters and had not learnt Roman alphabet yet. As a result, they cannot input text strings by JIS keyboard. We developed Kana-input navigation system for kids (KINVS) based on the cyber assistant system (CAS). CAS is a human-style software robot based on the 3D-CG real-time animation and voice synthesis technology. KINVS enables to input Hiragana/Katakana characters by mouse operation only (without keyboard) and CAS supports them by using speaking, facial expression, body action and sound effects. KINVS displays the 3D-stage like a classroom. In this room, blackboard, interactive parts to input Kana-characters, and CAS are placed. Mouse input method of KINVS are designed to use only single click and wheeler rotation. To input characters, kids clicks or rotates the interactive parts. KINVS reports all information by voice speaking and Kana subtitles instead of Kanji text. Furthermore, to verify the functional feature of KINVS, we measured how long kids had taken to input long text by using KINVS.
