Safe and Sound: Designing the Vocal Smoke Detector

The design of the vocal smoke detector incorporated psychoacoustic research to more effectively waken children. It also provided an opportunity to examine and improve the usability of an often-overlooked but critical household product. Human factors research into existing smoke detectors identified ergonomic and interaction opportunities in installation and use, which were addressed by an effective design and development process. The result of this effort was not just an appealing and usable product but a next-generation smoke detector that enhances safety by design.
