Title: CUBE 3D Glasses


1
CUBE 3D Glasses
  • Group 22
  • Lisa Litherland

2
Introduction
  • Lenses open and close to create 3D effect
  • Glasses operate on IR signal
  • IR signal cannot pass through walls of CUBE

3
Objective
  • Transmit signal to glasses using RF

4
Benefits
  • Can close final wall of CUBE
  • Full 6-wall virtual experience
  • Do not have to hold transmitter in front of you
  • No bulky cords

5
Original Ideas
  • Radio Shack TX/RX
  • Too bulky
  • Receiver needed to be plugged into outlet

6
Original Ideas (cont.)
  • Wireless headphones
  • Requires understanding circuitry of headphones
  • Expensive (60 - 500)

7
Linx Modules
  • Small
  • Light-weight
  • Easy to implement
  • Cheap
  • TX - 4.90
  • RX - 10.65

3 Main Stages
  • IR Detector
  • RF System
  • IR Emitter

11
IR Detector
  • Computer sends signal to StereoGraphics IR
    emitter
  • Detector captures IR signal
  • Sent to data in of TX

12
IR Detector
13
Input Signal
14
RF SystemTX
  • Powered by 5V wall power supply
  • Data in is from IR Detector

15
Transmitter
16
RF SystemRX
  • Powered by 3V lithium battery
  • Small
  • Light-weight
  • Data out sent to IR emitter

17
IR Emitter
  • Must amplify signal from RX
  • Power not adequate to turn on LED
  • Use a BJT transistor 2N2222A
  • Connect Vcc to emitter
  • Connect anode of IR LED to collector

18
Receiver Circuit
19
Testing
  • Oscilloscope
  • Viewed input signal
  • Checked shape of output signal
  • Measured input/output voltages
  • Frequency Counter
  • Frequency at input and output match

20
Testing (cont.)
  • Glasses
  • Check that LED makes lenses switch
  • Adequate range (200ft)
  • Signal goes through CUBE walls

21
Challenges
  • Short battery life
  • Flickering
  • Old fashioned oscilloscope
  • No Autoscale!

22
Successes
  • Designed and implemented complete working system
  • Completed work on time
  • Implemented low cost solution

23
Future Uses
  • Same design can be used to send data from person
    inside CUBE to computer
  • Heart monitor
  • Skin conductivity
