Voice Output Communication Aid Application for Personal Digital Assistant for Autistic Children

摘要

Let''s Talk! is a new VOCA (Voice Output Communication Aid) application for PDA for autistic children. This application has many advantages comparing to existing VOCA. We especially focused on an easy and simple manipulation. By tapping a symbol on a screen of a PDA with this application, a user can show his/her thoughts with pictures and sounds to others easily. It has 120 symbols based on daily life. There are 2 modes which can be switched depending on different situations of users. On gSupportive Modeh, a supporter shows the application to a user. On Self-use Mode, a user can tell what he/she wants directly with categories and symbols. It is possible to make original icons with a camera or a voice recorder in PDA. A user also can customize an original page by arranging icons he made or existing symbols.
