Advanced touch screens will allow you to feel the effect of touching different surfaces
At the University of Texas A&M (Texas A&M University), the development of a new technology of touch interfaces has begun, which will be able to transmit tactile sensations. It’s about adding another feeling to the process of working with gadgets. As Dr. Cynthia Hipwell argues, today we rely only on sight and hearing when working with electronics, and they have been overloaded for a long time, so it’s time to use touch. The ultimate goal of the project is to teach the machine to simulate touching physical objects with different types of surfaces. This will significantly enrich the application management menu, give new opportunities in virtual reality, and most importantly – radically change virtual shopping.
If it becomes possible to “touch” the product remotely, “feel” its texture, the shopping process will become much more attractive and more effective. The technical basis for the implementation of such an interface is based on the principles of multiphysics, when several different fields operate at one point in space – in this case, at the point where a person’s finger touches the screen. To do this, you need to take into account the effects of electric wetting or electrostatics, the geometry of the screen surface, the properties of its coating.
As well as fluid movements and charge transportation, the mechanics of finger contact with the screen, and what happens with the finger itself. As Hipwell argues, today in touch technologies everything is built around the screen, all efforts are aimed at the correctness of its operation and the correctness of touch recognition. But now it’s time to move in the opposite direction, to take care of the user himself and provide him with the opportunity to feel not only the fact of touch, but also its various forms. There are already developments, the first such interfaces should appear within the next five years.
