There is a good news for those who find it difficult to press tiny keys of their smartphone’s keyboard. An amazing writing technology has been introduced by German researchers that allows one to write text and emails in the air simply by waving their hands, as the system can smartly identify the drawn figures as letters and numbers, and later transforms them into digital form which can be entered into a text, email or a mobile phone application.
This technology being named as “Air Writer”, is used in a glove that can be worn in one’s hand. It can recognize the written stuff by detecting the movement of hands by the help of specially designed sensors being embedded inside it, that continuously records the movements. It can differentiate the nature of movements and recognize whether the wearer moves his hands for an ordinary task or for writing something. So, it ignores all those movements that does not resemble the general writing format, for example while eating, clapping or sweeping etc.
The computerized system captures and decodes the movements. It uses a Pattern Recognition Software to recognize the letters, as each letter has it’s statistical model stored inside the system. It has a total vocabulary of 8000 words, and can identify when all of them are written in block letters.
This is just like as if you are writing on an invisible board.
Error Rate of Airwriter:
Nothing is perfect, errors and omissions lie everywhere. This system has an error rate of about 7% that falls to merely 3% once the system gets use to one’s writing style. Or in fact it works like a learning algorithm.
This technology would replace the use of traditional keyboards. Scientist are however planning to see this system being woven into clothing in near future, so that it can be used everywhere. Further, the inventor Christoph Amma believes that it would be helpful to combine this system with Google Glass to eliminate the need of wearer to use any virtual keyboard for typing.
