e-compasses face an interesting technical issue - they are typically a "nice to have" feature of a device. The user is not willing to accept a big hit in performance for the added functionality provided. This presents a particular engineering challenge to the designers to minimize the size and power requirements. If they are successful, the added capabilities make it possible to delight the user - as the iPhone often does.
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.
