Engineers and scientists at the inaugural Augmented Human International Conference in France unveiled cutting-edge research on improving human perception with information from the Internet, customized databases, and biofeedback systems.
For example, scientists from the Telecommunications Research Center in Vienna altered an eye-tracking device and connected it to the Web. The system trains one camera on the user's eye and another on the scene being observed. The cameras are connected to a smartphone with a built-in compass and global positioning system, which enables the system to track the user's orientation and location.
The system also features sensors to show whether the user is looking up or down. By closing their eyes for two seconds, users trigger a request for information about the location in view. A remotely accessed computer then scans geo-referenced databases, such as Google Earth, and forwards the results to the user's cell phone.
