Smart phones: the next embedded interface

摘要

With excess computing power, built-in programmeble graphics, and multiple communications options, smart cellular phones provide a convenient and cap- able mobile user interface for many of the growing multitude of intelligent embedded devices. A few clicks on a portable smart phone can directly connect a user to security systems, industrial controllers, access-control systems, medical devices, environmental controls, and home-automation systems, and a smart phone can even replace the array of remote controls in most living rooms. For example, a production supervisor might receive a smart-phone e-mail alert at home directly from an ailing factory-automation device.
