Abstract:
In pixel art, users draw pictures by filling grids with colors. If a user's stroke deviates from the desired pixels, undesired pixels are filled with a wrong color. Thus, the users must draw strokes in a path created by the desired pixels. Depending on applications and settings, the grids are not always displayed, so the users sometimes must use paths with unclear widths. In this study, we conduct an experiment where participants fill various-size grids with and without the grids being displayed. We found that when the grids are not displayed or its size is small, the error rate is high. Additionally, the grid-filling tasks can be considered as steering tasks, and we found that the steering law holds even if the grids are not displayed. Thus, we believe that steering models are useful for defining the difficulty of the grid-filling tasks. We also discuss further experiments on grid-filling tasks.
