Potential Future Use:
Our latte art machine explores the new medium by combining the existing inkjet technology with the freedom of artistic expression.
Maglev Haptics! Butterfly Haptic's New User-Interface Technology
Ralph Hollis, Peter Berkelman, Bert Unger, Dan O'Halloran, Matt Pucevich, Joey Liang, Mark Dzmura, Kei Usui, Carnegie Mellon University; Beth Hollis, Butterfly Haptics
Magnetic levitation haptic devices allow users to interact with computed environments by manipulating a handle that is levitated by magnetic means. Users can translate and rotate the handle while feeling forces and torques from the virtual environment. The motors, encoders, linkages, gears, belts, cables, and bearings of traditional haptic devices are simply dispensed with in favor of a direct electrodynamic connection to the handle by the user.
Potential Future Use:
Haptic interaction with 3D virtual environments mediated through magnetic levitation provides unprecedented fidelity. In addition to many research applications, this approach can be used in computer-aided design, medical and dental training, visualization and interaction with multi-dimensional data, microsurgery, control of remote robot manipulators and vehicles, arcade games, and character animation.
Airborne Ultrasound Tactile Display
Takayuki Hosh, Takayuki Iwamoto, Hiroyuki Shinoda, Mari Tatezono, The University of Tokyo
Airborne Ultrasound Tactile Display will substantially improve the usability of 3D CADs or stereoscopic displays by superimposing a high-fidelity pressure field onto the graphic objects presented in 3D free space, and enable the users to physically handle these objects with their bare hands.
Potential Future Use:
The hand tracking system used in this prototype is a simple system comprised of a single camera. However, if the Airborne Ultrasound Tactile Display is combined with more sophisticated hand tracking systems, it would be a more practical haptic interaction system. It can also be expected that by superimposing acoustic radiation pressure onto the 3D graphic objects presented with stereoscopic displays, it effectively enhances the reality of the 3D virtual objects.
