Bluetooth pen lets you write in the air

SMK Corp has developed and recently demoed the "wireless input pen", which captures characters written in the air, transmits them and displays them on a monitor.

According to SMK, it is the world's first pen-type device that can do this and the company is currently applying for a patent.

The pen has a built-in "triaxial" acceleration sensor and Bluetooth functionality. The sensor detects the positional information, recognises the characters and wirelessly transmits the info to a monitor via Bluetooth.

As with most Bluetooth devices, the maximum transmission distance is about 10 metres and the it is expected that the pen will be used in place of a laser pointer in presentations and the like.
