Object Interactions & Gestures
How the user interacts with the objects in the scene
Each object in your scene can have multiple interactions that control how the user can interact with that object and the effect it has.
In wiarframe, you add interactions in the form of user stories, for example:
- when the user looks towards the Spaceman, the Spaceman should Spin
- or when the user taps on the Signboard, Open the URL …
Interactions are thus broadly broken into three parts, the object, the gesture and the effect. The effect can then either be a global effect such as Opening a URL or an object-specific action, such as Spinning. In the latter case, the target object can be different from the source object; for example, Tapping on the Signboard might make the Spaceman Spin.

Gestures
The following gestures can be used to trigger interactions in wiarframe. You can read the theory behind these gestures in the The Essential Guide to Mobile AR Gestures.
Tap
A tap on the screen that overlaps the object’s position.
Gaze (visual field)
Visual gestures that relate to the general direction of the user’s gaze.
Glimpse
The object enters the user’s peripheral view from offscreen.
Look Toward
The object enters the user’s central view — represented by the central third of the device screen. Multiple objects can be looked towards at once.
Look Away
The object exits the central view and enters the peripheral.
Cease Look
The object exits the screen.
Gaze (intent)
Visual gestures that relate to the intent of the user’s gaze.
Focus
The object is at the screen center for 1 second. Only the closest object is focussed on.
Stare
The object stays in focus (at the screen center) for 3 seconds.
Cease Focus
The object moves away from the screen center after being in focus.
Proximity
Gestures that relate to the user’s position in relation to an object.
Approach
The object enters social distance of the user (3m).
Reach
The object enters arm’s reach distance of the user (1m).
Embrace
The object enters intimate distance of the user (30cm).
Leaves Embrace
The object exits intimate distance of the user (30cm).
Leave Reach
The object exits arm’s reach distance of the user (1m).
Retreats
The object exits social distance of the user (3m).
