Abstract [en]

Computers which support user input on a display with multiple fingers have become increasingly common in recent years. One example is Microsoft Surface 2 with a 40 inch touch display which supports over 50 fingers simultaneously.

This thesis examines how you can implement a flexible framework for gesture recognition on 2D and 3D objects for the Microsoft Surface 2 platform.The supported gestures are tap, drag, flick, pinch, spread and rotation. The framework can also easily be extended to support new gestures.

The results imply that the framework provides intuitive interaction and good performance even when over 50 fingers are present on the screen simultaneously.

Abstract [sv]

På senare år har datorer med stöd för användarinput med hjälp av flera fingrar på samma gång på en bildskärm blivit allt vanligare. Microsoft Surface 2 är ett exempel som har en 40 tum stor touchskärm med stöd för över 50 fingrar samtidigt.

I denna rapport undersöks hur man kan implementera ett flexibelt ramverk för interaktion med gestigenkänning på 2D och 3D objekt för Microsoft Surface 2-plattformen. De typer av gester som stöds på objekten är tap, drag, flick, pinch, spread och rotation. Dessutom kan det lätt utvidgas för att stödja nya gester.

Resultatet visar att ramverket ger intuitiv interaktion och bra prestanda med över 50 fingrar på skärmen samtidigt.
