Abstract—Taiwan has become an ageing society that the ageing population is increasing. However the existing social software interface is designed for young people aged 25-34 so it is inconvenient for elderly people. There are a lot of researches related to the interface design for ageing people. However, most of these researches are related to either information ordering approach of the interface or size and ordering of images and texts. The objective of this study is to explore the use of subtracting design on social software by the ageing population. The object of study includes experimental group 17 ageing people aged 55 or above and control group 17 young people aged under 55. They operated the original Facebook interface (Interface A) and Facebook with interface of subtracting design (Interface B). This study has applied Paired-Samples T test testing the 4 indexes, including operation time, number of errors, mental workload and subjective satisfaction. The result shows that except the mental workload in control group, others are significant differences for all 4 indexes. This shows that Interface B is easier to operate than Interface A. Proper subtracting design of interface will help the ageing population using the social software, and effectively improve the using efficiency, subjective satisfaction, and reduce the level of mental workload.
Index Terms—Ageing population, interface design, social software, subtracting design.
