Its not just GPS – Google Glass contains the full range of sensors found in smartphones
Now that Google Glass is available to selected testers, many developers have been left feeling underwhelmed after Google only listed location capability, and no other sensors or functionality. All that is going to change with the discovery of hidden sensors in Glass – the entire range of sensors found in regular smartphones.
Now that Google Glass is available to selected testers, many testers (Who are developers and hackers) have been underwhelmed with the limited hardware Google Glass offers. However, Lance Nanek, a computer programmer and owner of a Google Glass, stumbled on gold – apart from the limited hardware available, there has been more hardware hidden inside the Google Glass, equivalent to what a standard Android smartphone would offer.
Originally believed to only be equipped with GPS due to the limited official API support, Lance Nanek has found out that with debug mode on, the full set of hardware becomes available to developers and hackers to take advantage of. Using an Android app he pushed into the Google Glass, he found that it boasts a long list of sensors(MPL Gyroscope, MPL Accelerometer, MPL Magnetic Field, MPL Orientation, MPL Rotation Vector, MPL Linear Acceleration, MPL Gravity, LTR-506ALS Light sensor, Rotation Vector Sensor, Gravity Sensor, Linear Acceleration Sensor, Orientation Sensor and Corrected Gyroscope Sensor). Also 3 location providers are available (Network, Passive and GPS). This is certainly more functionality than the originally reported single capability of "receiving location updates every ten minutes".
Lance Nanek has also commented that the sensors would bring the possibility of augmented reality apps that could combine input from the different sensors to provide, for example, information on restaurants just by looking toward them. Such capabilities are certainly exciting to look forward to, as developers start to utilize the newfound capabilities of the Google Glass.
