Specification
The invention (VR EM-CEE) relates to electronic switching of real-time/off-line
systems (i.e. multiple live telecast signals, switching between multiple VCR
signals, switching between multiple CD signals, or any other existing playback
system real-time or otherwise) via commercially existing head mount display
units (HMD's) that are currently used extensively in the virtual reality field.
Most virtual reality systems and products offer standard tracking with computer
based controls. VR EM-CEE exceeds these limits by offering video tracking
capabilities. With this feature, VR EM-CEE can produce real-time/pre-recorded
trackable scenes such as race cars, sky-diving, ski-slopes, sports, music videos,
travel vacations, and unlimited adventures or fantasies. For example, you are
watching a pre-recorded concert video wearing a head mount display unit (HMD)
as if you were sitting front row center, moving your head from side to side,
watching the stage and the action from different angles, while all along enjoying
stereophonic sound. Another example is you are sitting in a bar or your own
living room in Montreal, Canada wearing a head mount display (HMD) viewing a
live concert event taking place in Paris. You are moving your head from side to
side watching the stage and the action from different angles, as if you were right
there sitting front row center, while all along enjoying stereophonic sound.
We have found that most people will enjoy a complete experience if the
individual were given the liberty while viewing a video to manipulate his/her
environment by simply changing the angle at which they are viewing the scene.
This tracking ability of a video greatly enhances ones appreciation for the event.

The following refers to figure 1:
Item 1
The HMD with tracker serves as an immersive viewing apparatus giving wide
field of vision through a simulated projection screen, whose apparent size is
approximately 80 inches. The tracker transmits data in order to control viewing
position by controlling yaw, pitch, roll, and displacement.
Item 2
The invention (VR EM-CEE) receives tracker information from the HMD (while
displaying visual's for the viewer) and electronically manipulates this information
via a proprietary program burnt into the CPU of the invention. It outputs signals
that can either trigger different angles of view by manipulating the control
mechanism (such as a joystick) if real-time (live) video signals are used as
inputs (see item 3), or control different angles of view (using the same conceptas above) if off-line (pre-recorded) video sources (see item 4) are used as
inputs.
Item 3
A series of real-time video sources, such as three video cameras positioned
strategically to cover 172 of viewing area. Real-time video inputs are live video
inputs.
Item 4
A series of off-line (pre-recorded) play back systems, such as a digital CD player,
video game, or cable television.
Item 5
Control mechanisms (joystick, video switcher, or any commercially available
switching system) used to manipulate the functionality in switching real-time and
pre-recorded sources.
