Description

Intuiface's support for on-screen gestures enables you to use specific finger movements on a touch display to trigger actions.

These gesture triggers are associated with either the experience as a whole, an individual scene itself, or a static asset. That is, the gesture is captured if it is initiated in the experience, a scene, or a static asset that has been associated with the corresponding trigger.

The list of supported gestures varies by platform:

• Player on Windows: Intuiface supports 25 different gestures grouped into five categories, each of which can be used to trigger one or more actions. The list of gestures is here.
• Player on iPad, Android, ChromeOS, BrightSign, Samsung SSP: Intuiface supports the gestures Swipe Up/Down and Swipe Left/Right, each of which can be used to trigger one or more actions. You can see these four gestures listed here.

A common example would be to use the swipe left / right triggers to call the next / previous navigation action.

In the context of design for accessibility, performing gestures on static assets will enable you to capture large, gross motor gestures for every individual static item in a running experience. For example, create an on-screen trackpad for navigation. Or trigger text-to-speech without requiring perfect touch precision.

How a touch gesture is managed

The order of touch interaction gesture triggers is based on the Z position of the asset, meaning an asset nested in the front layer will always have priority over an asset on a layer beneath it. Gestures placed on a specific asset, scene, or experience will only work if there is no other asset that absorbs interaction on top of them.

A common mistake is to add interaction triggers at the scene level (such as is tapped trigger) and use swipe triggers at the experience level. In this case, the tap trigger will absorb the interaction, making the swipe gestures unusable.
