Shortening Selection Time Using Plural Cursor in Multi-display Environment and Its Preliminary Evaluation

This manuscript proposes a plural cursor to shorten selection time in multi-display environments. A plural cursor is a set of copies of an original mouse cursor, which move in a synchronized manner. Each copy is assigned on a different computer screen. This manuscript conducts an experiment to compare the performance of a normal mouse cursor and a plural cursor in a dual-display environment. The results show that the total path the plural cursor has taken on average was about half the distance of the normal cursor, but their total elapsed time was almost the same. The value of myoelectric spectrum a plural cursor was lower than that of a normal mouse cursor.
