In the past week I’ve been writing a small Windows 8 Desktop application that converts TUIO Messages into Windows Touch. It makes use of a new API in Windows 8 and won’t run on Windows 7.
It’s called TouchInjector and you can download it here: https://touchinjector.codeplex.com/ (no installation required)
Please tell me what you think and what features I should add =)
EDIT: created a codeplex project site (source code available too)
