Abstract
Abstract A visual simulator for obtaining the illusion of control presence in a remotely controlled vehicle comprises two television camera systems which are coupled to a cathode ray tube display carried by the head gear of the operator of the remote controlled vehicle. A video mixer or switch combines the images recorded by the two television camera systems into a single display. A position sensor attached to the helmet worn by the operator is connected to the video mixer to control the position of the scenes recorded by the two television camera systems on the cathode ray tube display.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
259 words
A visual simulator for obtaining an illusion of control presence in a remotely viewed scene comprising: a helmet adapted to be affixed to the head of a viewer; position sensing means effectively attached to said helmet to sense the position of the head of a viewer wearing said helmet; cathode ray display means carried by said helmet and effectively positioned to comprise the entire field of view of the wearer of said helmet excluding other visual stimuli; a first TV camera having pan and tilt motors which are effectively connected to said position sensing means to direct the view of said camera in directions corresponding to the direction of view of the wearer of said helmet; a control console having instruments and controls thereon to be viewed and operated by the wearer of said helmet to remotely control an aspect of the scene recorded by said first television camera; a second TV camera having pan and tilt motors which are effectively connected to said position sensing means to direct the view of said camera in directions corresponding to the direction of view of the wearer of said helmet; and positioned to record said control console; a video switch means connected between said first and second TV cameras and said cathode ray display means and connected to said position sensing means for control of the relative amounts of view presented to the the cathode ray display means by each of said first and second TV cameras, whereby an illusion of a control cockpit is presented the wearer of said helmet.

A visual simulator for obtaining an illusion of control presence in a remotely viewed scene comprising: a helmet adapted to be affixed to the head of a viewer; position sensing means effectively attached to said helmet to sense the position of the head of a viewer wearing said helmet; cathode ray display means carried by said helmet and effectively positioned to comprise the entire field of view of the wearer of said helmet excluding other visual stimuli; a first TV camera having pan and tilt motors which are effectively connected to said position sensing means to direct the view of said camera in directions corresponding to the direction of view of the wearer of said helmet; a control console having instruments and controls thereon to be viewed and operated by the wearer of said helmet to remotely control an aspect of the scene recorded by said first television camera; a second TV camera having pan and tilt motors which are effectively connected to said position sensing means to direct the view of said camera in directions corresponding to the direction of view of the wearer of said helmet; and positioned to record said control console; a video switch means connected between said first and second TV cameras and said cathode ray display means and connected to said position sensing means for control of the relative amounts of view presented to the the cathode ray display means by each of said first and second TV cameras, whereby an illusion of a control cockpit is presented the wearer of said helmet.
Claim 3
Dependent Claim
25 words
A visual simulator according to claim 1 wherein said first TV camera is mounted for controlled movement on a submersible vehicle controlled by said console.
Claim 4
Dependent Claim
31 words
A visual simulator according to claim 2 wherein said video switch is connected to said position sensing means to respond to the vertical movement of the helmet of the wearer thereof.
Claim 5
Dependent Claim
45 words
A visual simulator according to claim 3 in which said video switch means positions the view recorded by said second TV camera below that recorded by said first TV camera to produce the illusion of desk type console with a view over the top thereof.
Claim 6
Dependent Claim
21 words
A visual simulator according to claim 4 in which said video switch is connected to said helmet via a voltage comparator.
Claim 7
Dependent Claim
46 words
A visual simulator according to claim 5 in which said voltage comparator compares the voltage derived from a sawtooth generator which synchronized with the vertical synchronization pulse of said first and second TV cameras and a DC control voltage derived from the aforesaid position sensing means.
Claim 8
Dependent Claim
26 words
A visual simulator according to claim 6 in which said first and second TV cameras and said cathode ray display means comprise a stereoscopic TV system.
Claim 9
Dependent Claim
31 words
A visual simulator according to claim 1 wherein said video switch is connected to said position sensing means to respond to the vertical movement of the helmet of the wearer thereof.
Claim 10
Dependent Claim
45 words
A visual simulator according to claim 8 in which said video switch means positions the vIew recorded by said second TV camera below that recorded by said first TV camera to produce the illusion of desk type console with a view over the top thereof.
Claim 11
Dependent Claim
21 words
A visual simulator according to claim 1 in which said video switch is connected to said helmet via a voltage comparator.
Claim 12
Dependent Claim
46 words
A visual simulator according to claim 10 in which said voltage comparator compares the voltage derived from a sawtooth generator which synchronized with the vertical synchronization pulse of said first and second TV cameras and a DC control voltage derived from the aforesaid position sensing means.
Claim 13
Dependent Claim
26 words
A visual simulator according to claim 1 in which said first and second TV camera and said cathode ray display means comprise a stereoscopic TV system.
