I can definitely see some military/security-related applications for this suit; for better or worse... Anyway this is an exciting invention ! But the downside of the suit is that it does not filter surroundings based on a aggression/negative intent. Now I don't know how we could easily detect that an individual wants us harm : maybe faster heart rate, he/she is the only one following us and is either walking/running fast to catch up or tails us at a defined pace. Actually is an individual's walking pattern unique? If yes that could also distinguish everyone around you. Anyway that is the most exciting article I have read today. Time to get some work done now:D
