Reading / interacting with unrelated digital display information is incompatible with maintaining situational awareness as you walk (or drive) through a complex environment. Perhaps we need to ensure that people have paused before providing additional information. IF the information relates to the task at hand, such as a "heads-up" display in an aircraft, then it may enhance rather than hamper safety and efficiency. We must prevent people concentrating on their Googles Glasses from stepping out in front of trucks.
Neurosurgeons might in fact have a previously taken CT or MRI image of a tumor superimposed on the actually opened cranium to aid in the removal of it.
Similarly with the aircraft's data superimposed on the scene and changing based on where the eyes are looking: "is it a friend or a foe at 5 o'clock?"
Also, when I saw those specs, I assumed that they were short range wirelessly connected to some device being worn by the user. Thus, SAR concerns would be no different that a cell phone with a bluetooth tranceiver.
This resembles the MIThril project from the late '90s -- Google "mithril glasses" -- only with bigger databases, better AI, and more compact hardware. I expect to run into a lot of well-informed, distracted people in the near future -- pun intended.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
