Manual Setup

In the TouchFree Service Settings you can configure TouchFree for your Hand Tracking Camera and screen.

Use Manual Setup if you want to refine your setup with known distances and angles for your kiosk screen and camera position.

TouchFree Manual Setup

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

TouchFree 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.
