TMote receives NDI® streams and sends back TUIO events via OSC in response to touches. In this way, it allows you to create applications that can be remote controlled (via wifi) without having to implement a separate GUI for your iPhone or iPad. An implementation exists for Touchdesigner (by derivative) and can be downloaded here https://forum.derivative.ca/t/remote-controlling-touchdesigner-from-ios-devices/239406/39

Additionally, an Open Source example server for MacOS can be found here: https://github.com/mji1983/TMoteSampleServer/
