Getting Gesture Info
What is gesture?
The gesture in touch and multi-touch environment is the finger movement recognition. Fortunately in Usine the recognition works also with mouse movements.
For example if you move a single finger in one direction it’s called a panning (or pan). It can be a pan left, up, right, down.
Setup
To enable gesture recognition you have to activate the touch & Multi-touch option in the setup. Even if you don’t have a touch screen and you want to use the mouse.
After a restart of Usine, if the trace gesture option activated, gestures ID are displayed in the trace panel like:
General Idea
In Usine every panel can receive gesture information from the gesture outlet.
A gesture information is an array which contains:
- a number, the gesture ID
- several other value like the starting point of the gesture, the movement speed, etc stored in data1, …, data5.
