This paper describes a speech-input interface function, called speech shift, that enables a user to specify a speech-input mode by simply changing (shifting) voice pitch. While current speech-input interfaces have used only verbal information, we aimed at building a more user-friendly speech interface by making use of nonverbal information, the voice pitch. By intentionally controlling the pitc...

The processes involved in carrying out collaborative creative work and the ability to record and circulate the results are important. Previously, we proposed a label-capturing system for the group KJ method that uses anoto-based pens. The system instantly digitizes the positions and contents of labels containing ideas and thoughts, and then generates KJ diagrams for distribution. We also propos...

We present a directional and quantitative input method by clawing key tops, Keyboard Clawing. The method allows a user to input a direction and quantity at the same time without moving his/her hands much from the keyboard’s home position. As a result, the user can seamlessly continue typing before and after inputting the direction and quantity. We found that clawing direction is classified usin...

We present experimental results for two-handed typing on a graphical QWERTY keyboard augmented with linear strokes for Space, Backspace, Shift, and Enter—that is, swipes to the right, left, up, and diagonally down-left, respectively. A first study reveals that users are more likely to adopt these strokes, and type faster, when the keys corresponding to the strokes are removed from the keyboard,...

For effective digitizing of the group KJ-method (GKJ) activity, we had proposed a label capture system that utilizes an Anoto-based digital pen. The Former GKJ system can digitize the position and content of not only labels but also normal handwritten text. However, advanced edit operations such as changing the text color and emphasizing labels using a digital pen cannot be performed. In this p...

This paper addresses an initial game design process focused on user input methods. This process led to experimental bimanual mouse gameplay.

The fact that there exists a large number of homonyms in Chinese characters is a problem for the phonetic input method which is favored by most casual users for Chinese input into computers. A new
