Even today, Wireless Charging doesn't actually involve wireless transfer of charge. It requires physical contact of the wireless compatible rear charging cover and a charging plate to work. However, Microsoft claims that it has developed a true wireless charging technology. The new mobile charging project is called AutoCharge and requires no charging cables or pads. This new technology uses image recognition and solar charging to find a smartphone and charge it automatically, without any physical contact. Identifying the smartphone doesn't take much time and Microsoft claims that its light charger can detect a phone and start charging in just 0.3 seconds. The company used cameras to detect a device on a flat surface and check the level of charging. Once, the charger detected that the device needs charge; it will then fire off beams carrying charge towards the device. Microsoft developed a special indoor solar charging mechanism to make wireless charging a reality. The technology uses a straight beam of concentrated light which is pointed at the device to be charged. The low scatter makes sure that the charge is carried to the phone from the charger. Unfortunately, the device requires an integrated solar charging cover for this technology to work and it would take some time before this technology can be incorporated into everyday devices.
