Tuio-extended.js

This is a fork of Tuio.js, the original JavaScript implementation of the TUIO protocol.

Tuio-extended.js supports a very basic subset of the TUIO2 protocol, namely the the pointer (PTR) and token (TOK) components. They are currently not completely implemented.

Because the reference C++ implementation of TUIO2 supports WebSockets on the TuioServer, Tuio-extended also has a number of other changes:

• it decodes the TUIO OSC messages using osc.js, instead of using a local Node server
• the socket.io connection from the browser to a local Node server that relays the UDP messages to the browser is no longer needed
• if necessary for the original TUIO (v1) protocol, the Node Server is still available using src/server.js. Internally it uses the ws package instead of socket.io. Run it with: node src/server.js. It listens to localhost:3333 for Tuio messages over UDP, and sends over localhost:5000 for WebSocket connections.

Installation

Install with npm

npm install tuio-extended

Usage with Tuio2

The usage is the same as in the original library, but it offers two new methods in TuioClient for retrieving the two new input types. The one significant difference is that they give an array of pointer of token objects, instead of a JavaScript object. For instance:

var client = new TuioClient({host: 'ws://connection'});

client.on('refresh', function() {
  var pointers = client.getTuioPointers();
  var tokens = client.getTuioTokens();
  // they can be iterated
  pointers.forEach(...);
  tokens.forEach(...);
});
