  • Publication number: 20120188284
    Abstract: A touch apparatus includes a touch panel and a control unit. The touch panel has an input interface, which has a plurality of buttons and a zooming zone. The control unit is electrically connected with the touch panel. When a user touches one of the buttons, the control unit generates a prompt signal corresponding to the button, and a symbol corresponding to the button is magnified and displayed in the zooming zone. When the user then releases the button and doesn't touch the input interface, the symbol or a function corresponding to the button is inputted to the control unit. The touch apparatus has the advantages of assisting visually impaired people to use and simplifying information input.
