Scheduling home control devices: Design issues and usability evaluation of four touchscreen interfaces
Abstract
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-hour clock, 24-hour linear and 24-hour
dial prototypes are described and compared on a feature by
feature basis. An informal usability test with 14 subjects,
feedback from more than 30 reviewers, and the flexibility to add
functions favors the 24-hour linear version.
