Niboshi for Slate Devices: A Japanese Input Method Using Multi-touch for Slate Devices

We present Niboshi for slate devices, an input system that utilizes a multi-touch interface. Users hold the device with both hands and use both thumbs to input a character in this system. Niboshi for slate devices has four features that improve the performance of inputting text to slate devices: it has a multi-touch input, enables the device to be firmly held with both hands while text is input, can be used without visual confirmation of the input buttons, and has a large text display area with a small interface. The Niboshi system will enable users to type faster and requires less user attention to typing than existing methods.
