Welcome Screen
Launching TouchFree.exe will take you to the Welcome Screen.
Start configuring the Ultraleap camera module for your interface by selecting Setup Camera
Select your mounting position.
Our standard hand tracking SDK supports Above Facing Screen and Below camera module mounting positions within TouchFree. A third position, Above Facing User, is available by contacting Ultraleap.
You can launch this screen again by giving TouchFree focus (select it in the Windows menu bar or Alt+ā¹ to it), then pressing the āCā key on your keyboard.
Quick Setup (recommended)
Selecting Quick Setup takes you through three simple steps to get a TouchFree cursor on screen.
This process lets TouchFree know where your Ultraleap camera module is placed, relative to your 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
Distances for relative screen-camera placement are taken from the bottom-centre screen pixel row, to the top centre of the Ultraleap camera module.
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
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.
