We present a study comparing how people use space in a Tangible User Interface (TUI) and in a Graphical User Interface (GUI). We asked subjects to read ten summaries of recent news articles and to think about the relationships between them. In our TUI condition, we bound each of the summaries to one of ten visually identical wooden blocks. In our GUI condition, each summary was represented by an icon on the screen. We asked subjects to indicate the location of each summary by pointing to the corresponding icon or wooden block. Afterward, we interviewed them about the strategies they used to position the blocks or icons during the task. We observed that TUI subjects performed better at the location recall task than GUI subjects. In addition, some TUI subjects used the spatial relationship between specific blocks and parts of the environment to help them remember the content of those blocks, while GUI subjects did not do this. Those TUI subjects who reported encoding information using t...
