I have prepared two screenshots for you, both showing the live view of my visual workbench application. The live view directly processes the video stream delivered by the USB camera, calculates the hand position and draws the results. I use wxWidgets and OpenCV as third-party, open source dependencies.
The first screenshot shows the default view (on the top of the screen), the skeleton view (on the bottom of the screen) and the memory statistics view (on the right of the screen).
In the second screenshot, the default view is replaced by the fast view.
Read the paper to understand the difference ;).
I hope you enjoyed the demonstration. Stay tuned for new results in the coming months! E.g. we are building a 3D web browser prototype for evaluating gestural interaction.
