This is a great example of using gestures to interrogate your data. You can drill down, scroll and focus on charts of interest. I am not sure it will catch on though. When you watch the video you will see the presenter waving his arms around to get new information.
I think this sort of application of gestures (arm waving) would better suit a PowerPoint presentation when you are on stage. I can't see myself using this for day to day analysis of my organisations data and then make decisions. My arms will tire then will my patience. I am not sure how I would select a different department or period, change the versions or some what if analysis â€“ a Kung Fu Panda kick perhaps?
Will gestures be an easy way to view data? Probably only a small amount of data. Is it intuitive? Yes. Who will use it and when? Sales people in demonstrations at trade shows probably. What about real life?
