Ambient device
From Wikipedia, the free encyclopedia
Ambient devices are new genre of consumer electronics, characterized by their ability to be perceived at-a-glance (also called "glanceable").
Ambient devices utilize pre-attentive processing to display information, the ability for the brain to perceive information without any apparent cognitive load. The New York Times Magazine announced ambient devices as one of the Ideas of the Year in 2002 on the heels of a start-up company, Ambient Devices, releasing their first product Ambient Orb. The Ambient Orb maps information to a linear color spectrum and displays the trend in the data.
Research on ambient devices and ambience began at Xerox Parc with a paper co-written by Mark Weiser and John Seely Brown entitled Calm Computing. Associated fields include Ubiquitous computing (also known as Ubicomp) and Calm technology.
