Possible ways for physical calibration

[dulnan]

Currently the calculations in gyro-plane make assumptions about the physical setup of the screen and phone. Manual calibration would involve setting the physical screen size, the distance between the center of the screen, the angle at which the screen is tilted on the x axis (the case with a laptop screen) and the offset of the phone in relation to the center of the screen.

Ideas:

• Take a picture of the screen
• use accelerometer
• look at reflection of desktop screen on mobile screen
• ?!?
