Two-way touch display

    At Tokyo's Sign & Display Show 2008, Teraokaseiko introduced a curious concept: a two-way touch display. And she showed how to use it to play tic-tac-toe and sea battle.

    The 256 × 120 monochrome display is a transparent inorganic electroluminescent panel. The trick is that Teraokaseiko engineers placed resistive touch films on both sides of the display. The result is a device that recognizes not only touch, but also movement.

    According to the developers, their concept, if it ever becomes a commercial product, will be useful in devices for working with cartographic software and for games with two users.
