Abstract
The widget of a software keyboard, installed on the game consoles for text entry using only the gamepad, occupies a certain amount of the screen real estate. The reduction of the occupancy allows game designers to allocate a larger area for the game contents. We show KAI, a software keyboard indication method that reduces the screen occupancy of the widget while minimizing the degradation of input speed and accuracy. We conducted a comparative study of the conventional, KAI, and invisible indication methods with JoyFlick. The results showed that the conventional widget was the fastest and least erroneous among the three indication methods. In addition, the invisible widget was the slowest and most errornous. Therefore, for some software keyboards, KAI can be applied to reduce screen occupancy while minimizing the degradation of input speed and accuracy.
