Augmented Typing: Augmentation of Keyboard Typing Experience by Adding Visual and Sound Effects

People make choice of a keyboard for various features such as key arrangement, repulsion strength, stroke depth, and stroke sound. Currently these features depend on hardware; however, if a physical keyboard can be customized with software, users will be able to arrange it as their preference. In this paper, we propose augmented typing that augments typing experience by adding a visual and sound effect to a physical keyboard. We implemented a prototype system of the proposed system using projection mapping. To determine the effect and the usefulness of the system, in addition, we conducted evaluation experiments. Results of the experiments showed that the evaluation of sound effect was more variable than visual effect; users found that visual effects are beautiful, whereas the sound effects to be annoying.
