We suggested a new monitor environment with an adjustable virtual partition in order to incorporate advantages from both the multiple monitor and single monitor. We conducted a user study by making a prototype. Results showed that the prototypes enhanced the user work performance while it reduced the temporal demand. We believe that our design suggestion and the user study results can make a contribution to future single large monitor distributions from the user’s need of a bigger screen which provides a more immersive experience, as well as to a new computing environment such as laptops and tabletop computing that does not allow multiple monitor establishments.
