Abstract: To facilitate the monitoring of spatial and haptic movement and to provide tactile feedback, the invention replaces sheath-like glove human/computer interface devices with a manually operable exo-skeletal human/computer interface device (10) which comprises a wrist encircling means (11A, 11B) and a palm encircling means (16C) and a torsionally and laterally flexible manner (16D) connecting said wrist and palm encircling means, with said wrist encircling means being adapted in use to be proximate to and generally relatively fixed around the associated wrist of one hand of a user, with said palm encircling means being adapted in use to be proximate to and relatively fixed around the palm of said hand, with said palm encircling means having an overhand member (16B) overlying the back of said hand, further comprising at least one elongate generally resilient rib member (10A, 10B) extending at a fixed end thereof from said overhand member so as to be generally coextensive with at least one finger of said hand in o

Abstract: A haptic computer output device comprises a data glove 10 the finger and thumb extension 10A and 10B of which have spaced ring formations 13 and 14. Each ring formation 13 and 13 is formed with an inwardly-opening blind bore 21 spanned in gas-tight manner by a membrane 23 and conduits 20 within the ring formations selectively apply pressurised air to or relieve it from the bores 21 under the control of a valve assembly 34 in turn controlled by a computer 30. The computer generates images perceived on a visual system 32 by a wearer of the glove. Data concerning the spatial position and flexing of the glove 10 is transmitted via line 31 to the computer, which additionally generates a cursor on the visual system 32. When this interacts with other virtual objects to simulate a "touch" the appropriate bore 21 is inflated via valve assembly 34 to apply a tactile stimulus to the wearer of the glove.
