title: Extracting and understanding the relationship between components of the capacity in elderly people in terms of electrical device comprehension.
abstract: The purpose of this study is to extract components of the capacity which elderly people have in comprehending electrical devices and determine its relationship with the components. Initially, we proposed a hypothesis through examining previous studies. The hypothesis states that the capacity which elderly people have mainly consists of four components, i.e., motivation, working memory, logical thinking and experience with personal computers (PC) or mobile phones. Then, some tests were conducted to examine the hypothesis. In this research, elderly people were interviewed about their impressions and experience with electrical devices. Moreover, three tests were conducted including, card sorting, tasks using digital video cameras and a test to measure working memory. As analysis methods, the Quantification 1 was used to see which component was important. In addition, Boolean algebra was conducted to simplify the components and understand some relationships. As a result, a relationship with the components in electrical devices was revealed. Furthermore, the use of Boolean algebra and the Quantification 1 suggested that the experience with PCs or mobile phones was the most important component for elderly people.
