To confirm hand tracking is optimal for your chosen Camera placement, please ensure you check out the Testing Hand Tracking section.
The following Ultraleap camera module placements are supported in this TouchFree release.
- The Ultraleap camera module should be at least 10cm away from the highest point where the hand enters.
- The camera tilt should be between 15° to 85° from the horizontal.
- The Ultraleap camera module should be at least 10cm below the lowest point on the screen that users will interact with.
- The camera tilt should be no more than 20° from the horizontal.
- Ensure that the camera is a minimum of 1cm away from the screen.
Ultraleap will support a new Screentop mode camera placement in future software updates.
Our tool is designed to primarily assist kiosk manufacturers and integrators in determining the ideal positioning of the Ultraleap Camera for your setup. It allows for the customization and visualization of many different screen sizes and orientations and shows an accurate representation of the tracking zones and field of view for the Ultraleap Camera tracking devices.
Additionally, it will let you simulate your screen/kiosk setup and try different Ultraleap Camera placements to optimize the best placement and angle for your needs.
For extensive documentation around usage and controls as well as customization of the Camera Position Visualizer Tool, check out the dedicated User Manual.
Ensure that the user interface is contained within the camera module’s field of view. When choosing and positioning your Ultraleap camera module, consider the best position and/or making sure that UI elements are well within the field of view.

Ensure that there are minimal infrared (IR) sources and reflections within the field-of-view of the camera. These can reduce the quality of hand tracking.
Digital screens can act as mirrors, creating IR glare from the camera module’s own LEDs. To avoid this, place the camera outside the screen’s projection plane if possible.
Operating your Ultraleap camera in bright sunlight may also impact performance. To improve performance, consider a camera placement like “HMD” mode, or moving it to a less bright/reflective environment.
IR sources and reflections can be seen in the Visualizer.
Camera should be placed outside of the screen’s projection plane. Try to maintain this even when screen is tilted.
You should also ensure that there are no obstructions within the field of view of the camera and that the background is as simple as possible.
The Visualizer can be used to check for obstructions. In this example, hands are not tracked even though they are in the centre of the camera module’s field of view.
