There’s a couple ways,
One, check to see if your camera driver allows for horizontal/vertical flipping. Some camera drivers have a toggle for this.
If that doesn’t work, you can try calibrating. Start configapp.exe and hit enter. Follow the directions on screen. If you’re not using a projector, it’ll be a little harder to calibrate but guessing where the points lie will be fine (I’ve done it several times). Once you go through the calibration points, the orientation will be correct regardless if the camera is flipped or not.
So open configapp, adjust the sliders accordingly, hit ‘enter’ and follow the directions on screen. When you exit configapp (ESC), you will have a properly oriented configuration points.
The new touchlib that will be released has a built in flip feature that will allow you to press a button to flip the camera.
