The deficiency of any tactual feedback makes it unmanageable to typewrite or play games on a touchscreen gadget . So Swiss researchers have developed a newhaptic interfacethat uses microscopic vibrations that could one day make touchscreens feel like they have individual buttons , or even discrete textures . Can I interest you in a furred iPad ?
Developed by the École Polytechnique Fédérale de Lausanne in Switzerland , the paradigm machine features a touchscreen wheel , like an iPod , enhanced with a piezoelectric surface . When a electromotive force is applied that piezoelectric material vibrates , and while those microscopic vibrations are unperceivable to human touch , a very sparse bed of vibrating air is created which can be feel . By set the grade of voltage , and designate where on a touchscreen those quivering occur , the illusion of distinct buttons or alone textures can be created .
The obvious advantage to the enquiry is one day making on screen keyboards easier to habituate with sense of touch typing techniques , instead of the hunt and peck approach . But it also has program for those with disabilities , providing another room to expose braille characters , and letting visually spoil persons literally feel an image or user interface .
