|Wearable technology Q&A on Google Glass at Qualcomm.|
Google Glass is a heads-up display (HUD) for consumers. HUDs were invented for military fighter planes since flying requires intense focus and concentration in a distracting environment. Surprisingly, a large amount of today's computer science design best practices related to size, distance, and grouping U/I controls originated in the airplane cockpit.
Some user interface decisions seem obvious such as not putting the ejection button right next to the landing lights switch or not placing small, related, buttons far apart on a web page. But how do you figure out what's best? Paul Fitts, an Air Force Officer, modeled the theory behind human movement in a mathematical fashion. Based on his work, human machine interfaces have been refined leading to the development of technologies like the HUD. Technology should enhance an experience, not interfere with it.
