Abstract
The purpose of this paper is to present a comparison of mouse, keyboard and voice inputs to a complex map database query system. The system, developed at FOA 53 in Linköping, Sweden, is a multi-purpose one; the particular application involved here is one developed for monitoring water traffic on Lake Vättern. In a 4 − 2 within-subjects design, throughput was measured for mouse, keyboard, voice-english, and voice-swedish queries, both pre-composed and user-composed. An error analysis was also conducted. Results of the pilot study indicated that while voice was superior for pre-composed query entry, it was not necessarily superior for the entry of user-composed ones. System changes designed to improve performance in the voice and mouse input modes are discussed.
