Touchscreen technology offers such great potential for multimedia user interaction, but one can't help but feel like something is still missing. The clever Rene Lee has taken a step further with the development of the Zen tablet, offering a brilliant graphical display in conjunction with a tactile one.
Fingertips can do so much more than simply poke to convey commands, and this gadget takes full advantage. The Zen z-axis enabled device projects oscillating pixel rods that output three dimensional textures. Such a capability would be quite attractive to the visually impaired user, given the possibilities for presenting braille script and embossed computing icons. The Zen tablet even incorporates a sonic pointing system to direct users' tactile attention to specific locations on the screen with one speaker built into each corner.
