Microsoft thinks of a system to track the road when the GPS does not work

Earlier this month we saw a prototype built by Microsoft: The Menlo . We asked the utility of this device in light of the barometer, the necessary instrument for measuring atmospheric pressure. Today we get the answer through a presentation at the conference which occurred MobileHCI Lisbon.

The prototype Menlo serves to test a new technology useful while traveling. On some points, especially if covered by a high vegetation, the device may have difficulty docking the satellite signal. Menlo, thanks to the application Greenfield manages to cover that time frame.

The application processes the data received from accelerometer, the magnetometer and the barometer. These three sensors allow us to understand in which direction it is going and for how long, so when the GPS is active again unable to correct the previously calculated route.
