14 DAY TRIAL // Scientists Takayuki Iwamoto, Mari Tatezono, Takayuki Hoshi and Hiroyuki Shinoda, at the University of Tokyo, have managed to develop a way to drastically improve performances of those working with 3D graphic objects. The team has created a simulator of sorts, a device that, when completed, will allow users to handle tri-dimensional virtual objects in open spaces, without needing a mechanical glove or other gadgets attached to their bodies.
The basic principle of the new airborne ultrasound tactile display (AUTD) is the creation of a virtual 3D field with the use of ultrasound airfields. This generates high-fidelity pressure fields that can closely simulate objects. Past attempts at this type of technology included air-jets, which offer little focus to virtual fields, as well as mechanical interfaces to software programs, such as Immersion Corporation's CyberTouch device, which uses micro-transmitters placed on the user's hand to simulate the tactile feel of an actual object. However, they had limited success but, now, scientists in Tokyo hope that their newest invention will have the potential to exceed all limitations.
According to its developers, the AUTD is comprised of a pressure generator, which is shaped very much like a keyboard, a camera for tracking hand movements and a computer software to process the movements and create real-time responses. The only prototype in existence uses a regular camera for detecting motion, but the scientists at the University of Tokyo believe that by using high-fidelity special cameras, such as the Grimage system, the results could be several times more accurate.
The applications for such a device are mind-numbing. Virtual objects could be handled and edited in free space, by simply manipulating them with your hands. Entertainment applications, such as video games, are also considered for development. People have already begun pondering the possibilities on various forums and blogs, thrilled by the idea of finally being able to manipulate – live – any object they want.
