Only available for Windows users, MACOSX can't receive multi-touch info.
In Usine it is very easy to get multi-touch information within patches.
To enable multi-touch you have to activate the enable touch screen option in the setup-global.
The main idea is that every interface-design modules of Usine receive multi-touch information and send them to Mouse down, Mouse X and Mouse Y outlets.
These Outlets are array and their size is equal to the number of touch points on the control.
For example if you touch the control with two fingers, the mouse down will be an array of 2 elements.
We can now use an array module with faders to send this information directly to another module, for example a plug-in.
Here the 2 mouse Y values are sent to the 2 filter parameters of a synthesizer.
The gesture in touch and multi-touch environment is the finger movement recognition.
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.
If the trace gesture option activated in the trace-panel, gestures ID are displayed like:
In Usine, every interface-design modules can receive gesture information from the gesture outlet.
A gesture information is an array which contains:
|0||unknown gesture||down X||down Y||up X||up Y||speed|
|1||pan left||down X||down Y||up X||up Y||speed|
|2||pan right||down X||down Y||up X||up Y||speed|
|3||pan up||down X||down Y||up X||up Y||speed|
|4||pan down||down X||down Y||up X||up Y||speed|
|5||pan left bi points||down X||down Y||up X||up Y||speed|
|6||pan right bi points||down X||down Y||up X||up Y||speed|
|7||pan up bi points||down X||down Y||up X||up Y||speed|
|8||pan down bi points||down X||down Y||up X||up Y||speed|
|100||short touch (or click) single : when the user has pressed the screen or the left mouse button during more than 200 ms||X||Y|
|101||long touch (or click) single : when the user has pressed the screen or the left mouse button during more than 1000 ms||X||Y|
|102||short bi-touch : when the user has pressed the screen with 2 fingers during more than 200 ms||first finger X||first finger Y|
|103||long bi-touch : when the user has pressed the screen with 2 fingers during more than 1000 ms||first finger X||first finger X|
