The headset doesn't require the full viewing angle of the camera.
The front of the play area is 2.3 ft or 27.6 inches making a triangle from that line to the camera (24 inches away) gives you an angle of 59.8 degrees
27.6/2 = 13.8 13.8^2 = 190.44 24^2 = 576 576+190.44 = 766.44 Square root of 766.44 = 27.68 Sin^-1(13.8/27.68) = 29.9 29.9 * 2 = 59.8
If you follow that angle outward from the camera to the point where its lines intersect the rectangle (and are therefore 6.2 feet apart) they intersect 64.7 inches (or 5.39 feet) from the origin. Giving one large triangle made up of two 3.1X5.39ft right triangles.
As for part two, I didn't forget to include anything. The length is 9.8 ft from the camera to the end of the play area as is clearly shown in the picture. |
My mistake, they've mixed dimension conventions and I initially read the 9.8 ft play area length to be exclusive of the 2ft distance from the camera to play area
