Touchless Interfaces Design Guidelines

Interactive kiosks are everywhere.

Across the board touchscreens are the primary user interfaces for these devices.

People value the convenience of interactive screens, but want to avoid touching surfaces.

Our hand tracking technology adds mid-air gesture control to interactive kiosks. Ultraleap’s camera modules detect hands in mid-air, and our TouchFree software converts movements into an on-screen cursor.

There is no need to change system hardware or write any code. Simply connect your camera module, download TouchFree, and it will run invisibly on top of existing user interfaces.

The result is a self-service kiosk that can be used exactly like a touchscreen, but in mid-air. Customers can complete their entire user journey without once touching the screen. They can also switch seamlessly between touchscreen and touchless.

Research shows how digital displays that come to life catch attention, encourage interaction, and increase engagement.

The Call to Interact

When first using a touchless interactive kiosk there can be a lot to learn in a very short space of time. Instructional information should convey that the screen can be interacted with, and how.

Ultraleap have carried out real-world research to find the most effective instructional elements. Together, we call these elements the “Call to Interact”.

The Call to Interact attracts customer attention, brings them into position, and teaches them how to interact. Our evidence-based design recommendations make for a quick and smooth user experience.

Ultraleap recommend four elements that serve as the Call to Interact:

  1. Looping, on-screen instructional animation or video (required).
  2. Footprints graphic (stickers or mat on the floor).
  3. Nearby environmental signage.
  4. Printed instructional panel.

Together, these elements indicate to customers:

  • The interactive kiosk or display is touchless.
  • You use it by moving your hands in the air.
  • Where to stand to use it.
  • Where to position hands.
  • How to use hands to interact (for example, pushing buttons).

We have taken our research and developed detailed design guidelines for each of these Call to Interact elements for different types of interactive displays, kiosks, and signage here:
