The method is actually quite interesting. By exaggerating slight changes in color you can actually visually see someone's pulse (and other small changes in the environment.)
- deefourd 12y agoYep, the main difference is that wireless also works through walls, through a bed cover, if the person is facing away from the device, etc.
- ntoshev 12y agoI wonder if this technology will eventually become good enough to measure the heart rate of lying politicians from just video records. Bill Clinton would make an excellent example. Makeup might fool it though.
- SoftwareMaven 12y agoYou don't need to name a politician to imply lying. Naming one you believed didn't lie would be more interesting. The problem may be similar to the lie detector problem: if so much of what you say is false and, in some way, you really believe it, it may be indistinguishable from the truth.
