Manual Setup¶
Use Manual Setup if you want to refine your setup with known distances and angles for your kiosk screen and camera position.
Screen Height¶
Screen height is measured in centimetres from the bottom edge of the screen (excluding the bezel) to the top edge of the screen (excluding the bezel).
Note
Screen width is not needed here because TouchFree uses your screen resolution to determine the aspect ratio of the screen.
Screen Tilt¶
Screen tilt is measured in degrees with positive values tilting the screen backwards and negative values tilting the screen forward. This tilts around the bottom edge of the screen (excluding the bezel).
Camera Distance from Screen¶
Camera Distance from Screen is measured in centimetres from the bottom edge of the screen (excluding the bezel). Positive values represent a position in front of the screen.
Note
It is unlikely that this value would be negative.
Camera Rotation¶
Camera Rotation is measured in degrees with 0 facing up, positive values towards the screen and negative values away from the screen.
Note
see Measurement Notes for more information on these rotations.
Camera Left to Right¶
Camera Left to Right is measured in centimetres from the middle of the bottom edge of the screen (excluding the bezel) to the middle centre of the Ultraleap camera. Positive values represent a position to the right of the screen when facing it. Negative values represent a position to the left of the screen when facing it.
Camera Height¶
Camera Height is measured in centimetres from the middle of the bottom edge of the screen (excluding the bezel) to the middle centre of the Ultraleap camera. Positive values represent a position above the bottom edge of the screen (excluding the bezel). Negative values represent a position below the bottom edge of the screen (excluding the bezel).
Measurement Notes¶
Distances for relative screen-camera placement are taken from the bottom-centre screen pixel row, to the top centre of the Ultraleap camera module.
Angles are measured relative to 0° being directly upwards in the room, regardless of orientation or position. Note: this has changed since TouchFree 1.1.
