Abstract

The purpose of the current study was to find the grouping principle for smart home interfaces that most closely matches the thinking styles of Americans and Koreans. The independent variables were grouping method (NO: no grouping other than alphabetical order, FS: functional and then spatial grouping, SF: spatial and then functional grouping), culture and gender. 40 American and 40 Korean students' perceptions of the interfaces and their performance times with the interfaces were measured. Both female and male Koreans preferred the SF grouping, consistent with a cognitive style favoring thematic organization and field dependence. For Americans, females preferred SF grouping but males preferred FS grouping. Thus, only American males' preferences conformed to a cognitive style favoring functional organization and field independence. Cultural differences in grouping preferences need to be taken into account in design of smart home interfaces.
