Augmented/Virtual Reality System

The system should be waterproof, low-cost (less than $500) and durable for indoor and outdoor play in varying conditions.

Head unit:

see-thru color LCD glasses (decent resolution)
non-transparent backlit LCD cover for virtual reality play
digital compass (head yaw)
tilt sensor (head pitch/roll)
3D radar (sonar or IR transceiver mounted on two stepper motors) (disabled during virtual reality play
- collects 3D points used to dynamically build world map
- must be able to see thru windows
- the yellow bar attaches to the shaft of black motor and spins 360 degrees. the red motor mounts to the yellow bar and spins the blue transceiver ~130 degrees. the purple is the transceiver window. the red motor will go through an entire ~130 degrees for each step of the black motor. red motor scans down ~130 deg, black motor makes one step, red motor scans up ~130 deg, black motor makes one step, and so on. 1.8 degree stepper motors will generate ~14,400 3D points from which the map is built. the number of black motor revolutions needed per second is currently unknown. to conserve power, the black motor could be set to slow down when the scene stop changing (player is not moving) and set to speed up when change is detected.
speakers near ears, not headphones
light sensor, used to darken rendered objects
cable from body unit attaches to connector on back of head unit

Body unit:

adjustable belt and straps
front and back variable intensity impact solenoids
rechargeable battery pack
buttons on chest: on/off, direction pad, select, cd-play/stop, cd-next, cd-prev
NEC Vr5432 processor 167-200Mhz (datasheet)
64meg(?) sdram ram
available sdram dimm slot
16K(?) flash ram
- store configuration
- player name, height, height when ducking, stomache height (for weapon aiming) and shoulder height (for alternate weapon aiming). should be able to hold info for several players and allow easy switching between them. should store a couple more weapon heights, weapon slider on chest will select one.
rom bios to boot from cd or developer link
sound system, mono in, 3D stereo out
split-screen video system
cdrom drive on chest (audio and data cds)
dual expansion ports on back
belt clip to hang weapon
USB port for weapon
available USB port for optional devices
rear module will be larger than front module. belt has two adjusters, one per side. straps have four adjusters, one at bottom of each strap.

Weapon unit:

buttons: primary and secondary triggers, four toggle buttons (used to toggle options, can be used to prime/throw grenades, etc), weapon select wheel, toggle button for flashlight, weapon height selection wheel and a couple extra buttons.
shotgun style cocker for reloading
recoil
flashlight and batteries
digital compass (weapon yaw)
tilt sensor (weapon pitch)
weapon aiming is independant of head orientation
weapon aiming is only accurate when used close to the body and at stomache level
USB cable from body unit attaches to connector on weapon
all buttons will be placed on a rotatable barrel to allow left or right hand use.

Operating System:

Software:

AR game: see-thru LCD quake-style game that renders NPCs, weapons fire, items and special fx. It will use the radar to dynamically build the environment in realtime and random place NPCs. Will also support deathmatch and team-based multiplayer along with combined multiplayer + NPCs.
VR game: non-see-thru LCD quake-style game that renders everything. The radar will be disabled and the movement D-pad on the weapon will be used for forward, backward, left and right movement. The player will still turn, duck and jump with her body.
Enhanced Vision: simple program that operates in see-thru LCD mode and only renders polygon outlines in varying colors based on orientation and distance. A just-for-fun type of night vision.

Options

Multiplayer pack:

Pain pack:

Wireless weapon system:

receiver module clips to chest and connects to weapon cable
transmitter module attaches to multiple weapon bodies
- flashlight and batteries
- digital compass (weapon yaw)
- tilt sensor (weapon pitch)
- weapon aiming is independant of head orientation
- weapon aiming is only accurate when used close to the body and at stomache level
- battery pack
each weapon body can define a different orientation. the rocket launcher body will only be accurate when used on the shoulder and so on.
each weapon body can have unique features such as recoil and reloading
each weapon should have a shoulder strap or some means of storing when not in use

Misc options:

weapon won't be rendered on-screen because player can look down and see the weapon in his hands. icons should be used in the HUD so the player knows what the current weapon is. larger, temporary icons should be used when changing weapons for easier identification.
multiplayer games will require all players to sync up at a common location. each team will then need to sync at respawn locations. upon death, the players must walk back to their respawn before they can rejoin the game. the common sync location will be the deathmatch respawn point. players are invincible when standing within a X foot radius around their respawn point.
game can be loaded into ram, game cd removed and audio cd inserted. larger games would require a ram upgrade to do this.
