Handwriting Command Recognition and Digital Operation Using Digitalized Pen

We aim to realize a novel pen based interface system that provides various digital operations for both low-tech and high-tech people. In this paper, we developed an algorithm that associates drawn shapes, such as a circle and a rectangle, with operating commands, such as message input, address input. Using a commercially available digital pen, we confirmed that our proposed command recognition and operation algorithm worked well and outperformed usuale-mail sending operation in time. As a result, the accuracy of the command recognition is 93.8% and the response time of 90% strokes are within 100 ms.
