Keyboard Input by Movement of the Finger and Pointer using a Smart Device

摘要

Nowadays, users of smartphones use keyboard input, flick input and multi-tap input. Moreover, there are keyboard input and handwritten character input using a pen tablet for the PC. There is some input methods based on handwriting of characters in the air using Kinect and a web camera in much research. However, character input by using devices such as Kinect and a web camera are limited by the environment. The user also needs to learn a new input method because many systems use the original character input method. We reduce the burden of users by using a smart device with a high penetration rate. Moreover, we use the keyboard input method because it is a general input method. Therefore, users do not need to learn a new input method. Our method can be used by the various environments by using a smart device. Since character input from long distance can be performed using a camera of a smart device moreover, our method can be used broadly.
