You can clearly differentiate the texture of an orange and a peach just passing the fingers over them, right? But what if you could be able to differentiate the same textures tapping your fingers on the screen of a smartphone or tablet? Isn’t that a genius idea which may create a whole new era in our daily entertainment and research work? It is an idea of researchers from Disney Research in the United States. During the event, SIGGRAPH 2012, they unveiled a new technology which is well still under development. This technology may be able to make this hypothesis a reality.
The feature was previously named the REVEL, which stands for Reverse electrovibration and works as a kind of electrical injection. This is more likely a “Augmented Reality” and only future can tell what would probably happen to this. By the way, in this technology the user receives a poor discharge directly in his fingers when changing the screen, creating an oscillating electric field and thus conveying the sense that he is touching another surface.
The variation of the signal also allows different pulses can be created, resulting in distinct sensations, expanding the possibilities for manipulation in a touch device. The details of scientific work can be conferred in this articlePDF). The research work has to continue and there is no prospect of availability of the new feature on a commercial scale soon.
