Here is some background for those who are not familiar with the rules of academic research in the US. Usually, any experiments involving human subjects are subject to Univesity Institutional Review Board (IRB) [1] approval. IRB should evaluate both ethical and safety concerns. I recall having to jump through quite a few hoops just to do a simple touch screen gesture recognition test of a dozen willing fellow students. Apparently, the IRB approval step was skipped, or IRB failed to do its job in this case.
