Plaisant, C and Schneiderman, B ' Scheduling home control devices: design issues and usability evaluation of four touchscreen interfaces' lnt J Man-Machine Stud Vo136 No 3 (1992) pp 375-393 (24 refs) This article describes four different user interfaces supporting scheduling two-state (ON/OFF) devices over time periods ranging from minutes to days. The touchscreen-based user interfaces, including a digital 12 h clock, 24 h linear and 24 h dial prototypes, are described and compared on a feature by feature basis. A formative usability test with 14 subjects, feedback from more than 30 reviewers, and the flexibility to add functions favour the 24 h linear version.
