The TouchFree Application allows for a retrofit solution. This application provides a transparent overlay that enables you to use TouchFree interactions with any existing touch-supported application.

The TouchFree Application requires the TouchFree Service to run properly.

The TouchFree Service must be running in order to make use of the TouchFree Application or any Client built with the TouchFree Tooling. The TouchFree Service is built from within the Unity project found at ./TF_Service_and_Tooling_Unity.

The TouchFree Tooling provides a Client connection to the TouchFree Service where it receives positional and interaction data relevant to touchless interaction. Additionally, TouchFree Tooling provides extendable Cursors and Input Systems to allow the TouchFree Service's data to be used in different environments. It requires both the Ultraleap Tracking service installed to provide data from a camera, and the TouchFree Service (as above).

The TouchFree Tooling is available for two integration environments at the moment:

• Unity

  • The Unity version of TouchFree Tooling can be found in the project found at ./TF_Service_and_Tooling_Unity. Builds can be found on the releases page linked above.

• Web (JavaScript)

  • The JavaScript version of TouchFree Tooling can be found at ./TF_Tooling_Web. Built in TypeScript, it available in JavaScript form.
