Thanks for Vaid from our group be the presenter in the video!
We designed and evaluated a few natural hand gestures that are used to play three mini-games called "Happy Ball". The gesture framework was developed using a novel angular velocity method and a non-optical motion tracking system from Perception Neuron. The ball movement is controlled by hand gestures, e.g., performing swipe gestures to move the ball left and right. The ball needs to collect gift/reward objects and avoid hits by obstacles.
