Energy Based Stability Control of Haptic Devices

Introduction Humans interact with their world through the five senses, but the sense of touch is primarily used in the manipulation of objects. The word haptic refers to the sense of touch, and a haptic device is one that uses the sense of touch to convey information to the user. These devices provide force feedback to a user, and this quality allows for virtual reality simulations that “feel real”. One problem in the design of haptic systems is to minimize vibrations without sacrificing fidelity of the signals. Technology description Researchers at the University of Washington have developed a method for stabilizing a haptic interface, a computer control system, and a remote robotic manipulator through a novel algorithm. Business opportunity This novel control algorithm for stability control of haptic devices can be used to stabilize a wide range of virtual reality systems. For example, it can be used in medical robotics to control surgical arms or in training simulators of various types. Intellectual property position The UW has patents pending on this technology.
