Machines dominate our lives, from alarm clocks that wake us up in the morning to radios that lull us to sleep. Most of our interactions with automated machines and computers are problem-free, but more often than we would like, they can be irritating and confusing. This is frequently harmless, such as a VCR recording the wrong show, but when it involves a critical system like an autopilot or medical device it can be a matter of life or death. Taming HAL seeks to explain these miscommunications between humans and machines by exploring user interfaces of everyday devices. Degani examines thirty different systems for human use, including watches, consumer electronic products, Internet applications, cars, medical equipment, navigation systems onboard cruise ships, and autopilots of commercial aircraft. Readers will discover why interfaces between people and machines all too often do not work and what needs to be done to avoid potential tragedies.
