Welcome Screen

Launching TouchFree.exe will take you to the Welcome Screen.

TouchFree Welcome Screen

Start configuring the Ultraleap camera module for your interface by selecting Setup Camera

Select your mounting position.

TouchFree Mounting Camera Screen

Our standard hand tracking SDK supports Above Facing Screen and Below camera module mounting positions within TouchFree. To use our third camera position, Above Facing User, contact Ultraleap. At present, Above Facing User is only available on our restricted Early Access Program.

You can launch this screen again by giving TouchFree focus (select it in the Windows menu bar or Alt+ā†¹ to it), then pressing the ā€˜Cā€™ key on your keyboard.

Selecting Quick Setup takes you through three simple steps to get a TouchFree cursor on screen.

TouchFree Setup Screen

This process lets TouchFree know where your Ultraleap camera module is placed, relative to your screen.

TouchFree Quick Setup Screen

Position your finger directly over the target shown on screen and press the Space Bar to progress.

Note: Quick Setup will approximate your kiosk-camera setup, but if you have known measurements, we recommend you also use Manual Setup to make adjustments.

Manual Setup

Manual Setup lets you refine your setup with known distances and angles for your kiosk screen and camera position.

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.

TouchFree Measurement Notes

Regardless of below/above camera mounting:

  • Angle toward the screen (away from user) is a positive value.
  • Angle away from the screen (towards user) is a negative value.

Angles are measured relative to the horizontal plane.

Checking your Screen-Camera Setup

TouchFree Advanced Setup Screen

If the cursor is not correctly aligned with your hand you can refine settings in Manual Setup, or retry Quick Setup.

To check your calibration use the Check Setup button. Move your hand to each corner to confirm cursor alignment and test the buttons.
