Abstract

Disclosed is a flexible glove fitted with a Bourdon tube extending along various articulated portions of a hand inserted within the glove, in addition to a number of position sensors sensing finger movements, to provide both input and output functions within a virtual reality computing system. With this glove, the user is provided with real-time tactile feedback.

Tactile Glove for Virtual Reality Systems

      Disclosed is a flexible glove fitted with a Bourdon tube
extending along various articulated portions of a hand inserted
within the glove, in addition to a number of position sensors sensing
finger movements, to provide both input and output functions within a
virtual reality computing system.  With this glove, the user is
provided with real-time tactile feedback.

      The Figure is a perspective view showing an example of the
glove 1 with the Bourdon tube structure 2, which is fastened in place
within the glove so that a single Bourdon tube 3 extends along and
under the thumb and each finger of a hand within the glove.  Each
Bourdon tube 3 is formed into a curved shape simulating a curved
configuration of the associated finger of the user.  When a fluid
(pneumatic or liquid) pressure is applied to the Bourdon tube 3, it
is straightened.  The degree of curvature is closely controlled by
controlling the fluid pressure.  Each Bourdon tube 3 is connected to
a supply tube 4, through which fluid pressure is applied by a device
(not shown) driven by a computing system.  The supply tubes 4 extend
away from the glove, along the arm of the user, in a bundle 5 and are
branched apart for connection to the Bourdon tubes 3.

      During operation of the virtual reality system, the amount of
pressure applied to each Bourdon tube 3 is controlled very precisely,
so that, when the system senses a displacement initiated by...
