There's a connection between what we see and what we feel according to recent experiments with tactile sensations and how visual stimulation affects them. In essence, seeing is touching if the research is correct. Most videos that come to us from DigiInfo are very compelling and highlight cutting-edge technology. This one is lukewarm and the science behind it is dubious, but the technology used in the experiment is pretty nifty. Using glasses that display an image of either fire or ice 30 centimeters in front of the viewer, they're able to simulate sensations of hot or cold. The applications of such technology are relatively limited - education, gaming, and potentially rehabilitation are among the possibilities. Still, it makes for a neat video to watch:
