18 month development process
Primary Goals
Flexibility of space
Ease of use
Flexibility of lighting
Difficult to mess up

6. Flexibility of space Teach from multiple locations
Teach sitting with the circle of students
Teach a class broken into small groups

7. Ease of use

8. Flexibility of lighting
Professors wanted to be able to not turn off lights
They were used to 10 year old 2200 lumen projectors
BRIGHT PROJECTORS
We considered using Epson's dual bulb projector, but decided the 5650 was good enough.
Worked with the lighting company get the best presets on the light switches -- but still have it be easy
Some professors wanted lights to automatically adjust when projector turned on, but obviously couldn't agree what the lights should do.

9. Difficult to mess up Volume goes to 80% whenever input is switched
No 90 minute timeout (instead turn off based on signal)
No built in computer
