Interactions¶

Air Push¶

Preferred interaction when close to screen

AirPush mode uses the speed and direction of the user’s hand to determine when they are gesturing forward to make a selection. It works for the widest range of users, and interactions can be performed at any distance from the screen (within the camera’s field of view).

AirPush is the default mode. We recommend AirPush for most touchless kiosks and screen-based experiences.

Touch Plane¶

TouchPlane mode uses an invisible virtual ‘plane’ in the air in front of the screen. A click event is triggered whenever a users’ hand moves through the plane, like a virtual mid-air touchscreen. As such, the interaction works at a fixed distance from the screen which can in be adjusted in TouchFree settings.

Hover & Hold¶

Preferred interaction when using at distance from screen

For non 1:1 setups, typically at a larger distance from the screen, hover & hold tends to be the easiest, most reliable and most intuitive interaction.

Hover & Hold is a simple way to interact. Users simply move the cursor into location, hold still as the cursor shows a short, timed animation, then a click event is triggered. The time before a click event is triggered can be adjusted in TouchFree settings.

Hover & Hold works with selecting, however does not work with other interactions such as scroll and drag so we recommend using UI buttons for scrolling and carousels.

Touchscreen Hybrid¶

TouchFree is able to work seamlessly with touchscreens, providing users with the choice of how they want to interact based on the individual and the situation. Here are a few recommended best practices for setting up TouchFree with touchscreens.
