Jump to navigation Jump to search

TUIO is a protocol intended to connect multitouch environments such as laser scanners, multitouch tables, etc. to interactive installations. It is based on OSC, which itself is the network-based successor to MIDI. Today, many common devices can send TUIO, including IPhones, IPads, Android devices, Kinect Controllers, Wii Controllers and many more.

Using TUIO in your setup is easy. We will use an Android phone for the example setup.

1. First connect the MXWendler server and the Android device over a network, e.g. WLAN.

2. Open 'OSC' in the MXWendler IO Devices Settings: (A)

Menu: Settings → IO Devices → OSC

3. Activate 'Receive OSC'. (B)

4. Set 'Listen on Port' to '7000' (default). (C)

5. Turn on 'Log received Data' (reset later for better performance). (D)
