Give us tactile interfaces!
Most recently, I informed the Hubs about the upcoming conceptual changes in the CAD interfaces . Perhaps the touch-screen will really change the idea of the work of a design engineer of the future. But even more radical technologies are on the way. A group of researchers from the University of Tokyo has developed a much more advanced system for the representation and management of spatial objects. They created three-dimensional interactive holograms, a touch to which you can feel.
For the formation of three-dimensional images of various subjects, the authors used a holographic display of the Provision Interactive Technologies company; holograms created with its help visualize objects at a distance of 30 cm from the display surface. These are super-advanced technologies, but scientists at Tokyo University have been able to improve them. Under normal conditions, putting the hand to these images, the operator will not feel anything, but the scientists decided to change it.
They developed a system for transmitting tactile sensations, combining a holographic display with an array of 324 ultrasonic transducers. The directional sound radiation influences the hand that is in the focus of the holographic image, and due to the interference effect, scientists manage to create tactile sensations. But that's not all. Data on the spatial arrangement of the operator’s hand are obtained by special controllers; for this purpose, retroreflective elements are attached to the tips of the middle fingers, to which radiation from infrared LEDs is incident. All this together: a hologram, tactile sensations and tracking movements and gestures of the operator - allow you to create a unique interface.

According to the authors, the technology can be used in computer-aided design systems, however, more fantastic prospects for technology can be found in the gaming industry.
