CHI (Cheap Haptic Interface)

Stanford University, 2001 - $11,500

According to research and marketing firm CyberEdge, the virtual reality market was valued at $24 billion in 2000 and is expected to grown by more than 50% each year this decade. To be a part of that growth, this E-Team from Stanford University developed a Cheap Haptic Interface (CHI) system that provided a cheap technology for a multitude of uses.

A haptic interface is a design technique that allows people to use their sense of touch to interact with remote or virtual environments on computers. The user of this type of system can "touch" objects simulated on a personal computer by interacting in real life with motors, like small robots, or other physical devices. By grasping one of the limbs of the robot, the user can exchange information with the PC and move the position of objects in the interface. The technology has several potential applications, such as making computers more accessible for people with disabilities, training people for tasks requiring hand-eye coordination (such as surgery), and playing games.
