SMK Corp developed "Wireless Input Pen," which can transmit characters written in the air and displays them on a monitor.
The pen was exhibited at the company's exhibition "TEXPO 2008," which took place in Shinagawa, Tokyo from June 4 to 6, 2008.
The pen has a built-in triaxial acceleration sensor and the Bluetooth function. The sensor detects the positional information and recognizes the inputted characters. The characters are wirelessly transmitted to a monitor via Bluetooth. The maximum transmission distance is reportedly about 10m. It is expected that the pen will be used in place of a laser pointer in sales presentations.
According to SMK, it is the world's first pen-type device that can transmit characters written in the air to a monitor and the company is currently applying for a patent. Thus far, Anoto AB of Sweden and CandleDragon Inc have prototyped a pen that can transfer characters written on paper to a monitor, etc.
