Not too far in the distant future, we may start seeing radar technology being integrated into our mobile phones courtesy of Nokia. “Mobile Radar” was developed by the Nokia Research Center and was unveiled during “Demo House 2010” at Aalto University near Nokia’s base camp in Espoo. Essentially what “Mobile Radar” would offer is to use a mobile phone
to measure an object’s distance, speed, and direction – almost exactly the same technology found in radars used by police officials. Additionally it can be used to adjust the volume while playing a song without ever touching the device; it can even work if an object is blocking it. There can be many more uses with this kind of technology – such as integrating it with home security systems and the interaction through video games. So far it looks very promising and may appear in future Nokia handsets.
