Claim 1
Independent Claim
199 words
An information display system for providing event and direction indication information to an operator, comprising: means for receiving information signals having event and direction indication characteristics; means for transforming said received information signals into direction indications in a fixed reference coordinate system; an egocentric coordinate system centered in the head of the operator, and wherein spatial orientation of said egocentric coordinate system varies with spatial orientation of the head of the operator; means for transforming said direction indications in said fixed reference coordinate system to direction unit vectors in said egocentric coordinate system; a plurality of tactiel stimulators associated with the head of the operator to provide selected tactile stimuli thereto, and wherein said plurality of tactile stimulators are statically disposed generally omnidirectionally in 360 degree space about said egocentric coordinate system centered in the head of the operator and means responsive to said direction unit vectors in said egocentric coordinate system for actuating selected ones of said plurality of tactile stimulators at locations on the head of the operator corresponding to said event and direciton indication characteristic of said received information signals, thereby providing the operator with selected tactile stimuli corresponding to said event and direction indication information.
Claim 2
Dependent Claim
199 words
An information display system for providing event and direction indication information to an operator, comprising: means for receiving information signals having event and direction indication characteristics; means for transforming said received information signals into direction indications in a fixed reference coordinate system; an egocentric coordinate system centered in the head of the operator, and wherein spatial orientation of said egocentric coordinate system varies with spatial orientation of the head of the operator; means for transforming said direction indications in said fixed reference coordinate system to direction unit vectors in said egocentric coordinate system; a plurality of tactiel stimulators associated with the head of the operator to provide selected tactile stimuli thereto, and wherein said plurality of tactile stimulators are statically disposed generally omnidirectionally in 360 degree space about said egocentric coordinate system centered in the head of the operator and means responsive to said direction unit vectors in said egocentric coordinate system for actuating selected ones of said plurality of tactile stimulators at locations on the head of the operator corresponding to said event and direciton indication characteristic of said received information signals, thereby providing the operator with selected tactile stimuli corresponding to said event and direction indication information.
Claim 3
Dependent Claim
67 words
The information display according to claim 1 wherein said direciton indications transforming means further includes means for sensing the spatial orientation of said egocentric coordinate system centered in the head of the operator to take into account the spatial orientation of the head of the operator in transforming said direction indications in said fixed reference coordinate system to said direction unit vectors in said egocentric coordinate system.
Claim 4
Dependent Claim
44 words
The information display system according to claim 1 further comprising a support enclosure worn by the operator and wherein said plurality of tactile stimulators associated with the head of the operator are supported by said support enclosure worn on the head of the operator.
Claim 5
Dependent Claim
22 words
The information display according to claim 3 wherein said support enclosure worn on the head of the operator comprises a protective helment.
Claim 6
Dependent Claim
65 words
The information display system according to claim 1 wherein said means responsive to said direciton unit vectors in said egocentric coordinate system for actuating selected ones of said plurality of tactile stimulators at locations on the head of the operator is operative for actuating selected ones of said plurality of tactile stimulators corresponding in location to said direction indications of events in three dimensional space.
