Ultraleap’s camera modules and TouchFree software provide touchscreen emulation by detecting a user’s hand in mid-air and converting it to an on-screen cursor.

TouchFree is designed to run invisibly on top of existing user interfaces without the system needing major modifications.

How it Works

TouchFree runs on top of your existing UI, providing touchless interaction without writing a single line of code.

Provides familiar touchscreen-style interactions:

  • A user’s hand is detected, and shown as a cursor displayed on the screen.
  • Items are selected by a simple ‘Air Push’ motion like tapping the screen.
  • To drag or scroll, ‘Push forward, then move’.
  • See Ultraleap’s Design Guidelines for more details on interaction methods.
