@Duane: If it's not visual, can it still be called augmented reality?
Most certainly- but we tend to refer to AR experiences that don't require real-time rendering as "computer vision", which is really utilizing any of the sensors (including the camera) to access information or trigger actions. Image recognition and visual search is a very good example of this. Also using sensors like GPS (the Nokia example mentioned earlier) is a popular form of Computer Vision.
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.
