Form factor matters.

Previous research reports a number of different variables that affect group processes. We examine situations in "triple space", in which people must manage (1) complex problem-solving tasks, (2) social interaction, and (3) the meaning making process of the changing representation created by others on shared mediums. In this case, the complex problem-solving task is solving a shared Sudoku puzzle. Two findings follow from the current study. People in both the laptop and tablet conditions talked less than people in the paper-control condition, but only people in the laptop condition experienced a significant decrease in positive emotion.
