Presenting a Fire Alarm Using Natural Language: The Communication of Temporal Information
Language comprehension is an important issue in fire alarm systems. This study focuses on the expression of temporal information in a fire situation. Both absolute time and relative time were designed to compare the expression types of temporal information. The time sequence and spatial sequence were designed to explore the expressions of a complicated fire that has more than one point of origin. A 5-point Likert scale and ranking task were used to evaluate the comprehensibility of different presentation forms. The results show that using absolute time to describe the point of origin of the fire and its spreading state aided better comprehension. The mechanism and potential reasons are also discussed. In addition, some suggestions for future designs of fire alarm systems are proposed.
