Abstract:
The demand for smartwatches has been growing in recent years, and opportunities to perform operations on smartwatches are increasing. However, the screen size of smartwatches is small, and complex input such as character input is often erroneous. Another problem is the high screen occupancy of software keyboards. Therefore, there is a need for a better input screen design for smartwatches. Since Japanese input has more characters than alphabetical input, it is necessary to provide a large number of options. Therefore, we have proposed a new Japanese character input screen design for smartwatches. The user interface design should allow a large number of selections to be made on a small screen with touch input. The proposed design has keys arranged in a circular pattern at the edge of the screen, allowing for a large key display while minimizing screen occupancy. The input operation is by touch and slide, and the slide allows multiple selections to be made from a single key. This design has resulted in superior input speed and accuracy, as well as screen occupancy, compared to the previous design. Investigate and evaluate UI designs that allow users to more comfortably input characters.
