I find the project to be unsettling and interesting at the same time. It is interesting to be able to turn the recording results back over to the public and draw some conclusions from them.
For instance, there was a comment worrying about "the computer" de-socializing us as a species. It seems to me that a "stone face" is just the default expression when we are not directly conveying non-verbal information. How often do you think you make faces during deep sleep?
Do people normally smile at things they are considering buying? This is a genuine question. I can't remember smiling at an inanimate object i was thinking of purchasing. That being said, i DO smile and laugh or cringe at times while reading a book on a computer, or watching a video, so maybe there ARE times?
