Flexible Gesture Recognition for Immersive Virtual Environments

Deller, M., A. Ebert, et al. (2006). Flexible Gesture Recognition for Immersive Virtual Environments. Information Visualization, 2006. IV 2006. Tenth International Conference on.

Summary:

Deller et al.'s publication used hand-gestures with a P5 glove to control various aspects of a desktop environment. The glove will allow users to manipulate virtual objects in three dimensions.

The apparatus that the authors used is the P5 glove, which has 5 finger sensors and an infrared tracking system. The glove was used to create hand gestures, where a gesture is a hand position held for approximately half a sentence. Gestures are stored as sensor vector templates, and each new gesture is compared against the gesture library via a simple distance measurement.

The authors had users test the system.


Discussion:

The application of hand gestures is simple, such as the use of distance for gesture classification. Using a more complex classifier might improve their accuracy, but with only 5 sensors the gestures might be simple and different enough that a simple solution is necessary.

I hope that presenting some results, at least in user study form, is the norm for the remaining papers we read. I cannot really take anything from this paper since I'm not sure if anything works well. The methods are so simple that I can implement them quickly, but it would be nice to have a baseline to compare to.

It's obnoxious not to see results. I can write a cool sounding paper if I don't have to actually implement or test anything.

Occam's razor - why make it more difficult (especially when you don't report your results)? If I didn't have to report my results I would just randomly pick a gesture for classification.
