Abstract

Ubiquitous computing takes computation from the desktop environment and moves it into every area of our lives. Instantaneous information and computation will be distributed over an array of small wireless networked devices. These can be embedded in daily artifacts such as appliances, light switches, stereos, cellular phones, and watches. This capability will revolutionize computation, allowing it to take place anywhere and at any time. Rather than accessing data only via a monitor and keyboard, one might access data via voice-activated commands and view it on a neighboring wall. Computation will be everywhere. Such technology will allow doctors to access medical histories during surgery uninhibited or help an architect inspect blueprint changes on site. For such a revolution to occur, however, an infrastructure and affordable technology needs to be established. This presentation will consist of a history of ubiquitous computing and an examination of current research developments. Advancing battery technology, wireless protocols (Bluetooth, IEEE 802.11, and LTE), applications, current examples, and social implications will be discussed.
