    The Future of Feel

    TeslaTouch infuses finger-driven interfaces with physical feedback. The technology is based on the electrovibration principle, which can programmatically vary the electrostatic friction between fingers and a touch panel. Importantly, there are no moving parts, unlike most tactile feedback technologies, which use vibration motors. This allows for different fingers to feel different sensations. When combined with an interactive graphical display, TeslaTouch enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch. For example, when dragging a file, the level of friction could convey the file size. Objects could "snap" into place when designing a presentation. Or perhaps with a quick "rub" of your email application's icon, you could sense how many emails are unread. Finally, imagine a (flat) touch keyboard where the virtual keys can be felt. The possibilities are endless.

    Tactile feedback based on electrovibration has several compelling properties. It is fast, low-powered, dynamic, and can be used in a wide range of interaction scenarios and applications, including multitouch interfaces. Our system demonstrates an exceptionally broad bandwidth and uniformity of response across a wide range of frequencies and amplitudes. Furthermore, the technology is highly scalable and can be used efficiently on touch surfaces of any size, shape and configuration, including large interactive tables, hand-held mobile devices, as well as curved, flexible and irregular touch surfaces. Lastly, because our design does not have any moving parts, it can be easily added to existing devices with minimal physical modification.

    TeslaTouch was developed at Disney Research, Pittsburgh. The industrial design of TeslaTouch handheld prototype was done in collaboration with Mark Baskinger, CMU School of Design. Disney Research is a network of research laboratories at The Walt Disney Company. Key proficiencies are in Computer Graphics, Video Processing, Computer Vision, Robotics, Radio and Antennas, Wireless Communications, Human-Computer Interaction, and Behavioral Sciences, with developing competency in areas such as data mining and displays.

    Mmmmm friction on skin, man! Expand your mind!
