I have written before about how computers will be used to enhance imaging data to give us a much clearer view of human physiology.
The newest example of this comes from MIT, where researchers have been able to enhance video to reveal subtle movement and color changes that heretofore could not be visibly detected. See Medgadget’s article here. The linked video is astounding.
As applied to non-invasive sensing, this is one of the most exciting advancements I’ve seen. The implications for medical device design are far-reaching.
I can also envision the technology being used as a training aid. For example it could reveal the kinisthetic subtleties that go into expert athletic and artistic performance. Athletes and artists could then learn to mimic expert movement to improve their own performance.
