our senses are set up to know how to filter out 99% of what is coming into them. That is why they work, and that is what is beneficial. I think that is why AR needs to focus on… You look at what I can find out on Google or whatever, the amount of information is just astronomical. The hard part, the intelligent part, is how do you figure out that one tenth of 1% that I actually care about at this given second?
Researchers from Tokyo's Meiji University, haven't quite figured out how to build that filter but they do have a neat way to avoid overloading your senses. In the F.A.R.vision system project, the level of augmentation is determined by your eyebrows. Bend them inward (that is, frown) to make virtual objects more visible.
You may look silly, but that explains why terminators always had an angry face when hunting down Sarah Connor. More information can be found here, in Japanese.
