Haptic communications
First Claim
1. A method of activating a haptic output device of the kind responsive to signals defining directional force comprising receiving a series of signals defining a multiplicity of data packets, each packet defining a directional force applied at one location for transmission to the current location, determining from packet data the information defining a position to which a haptic output device is expected to move, using current positional data to generate output signals defining force and direction and applying a damping factor to said force and direction signals to slow the rate of movement from a previously defined position towards the current defined position.

Abstract
A haptic output device in combination with a network has its effective inertia increased by a controlling computer algorithm whereby potential latency effects of the network are damped out.

- 8. An interactive haptic output terminal in combination with a bi-directional transmission arrangement, the terminal comprising at least a haptic output device and control means, said control means receiving signals from said haptic output device to determine a current position for said device, and to determine from signals received from said transmission arrangement a preferred current position for said haptic output device, said control mean determining an output force and direction required to move said haptic output device from the current position to the preferred position and further modifying said output force and direction using a damping factor to slow apparent movement between the positions and outputting signals defining the modified force and direction.
