Palatable food stimulates neural systems implicated in drug dependence; thus sugar might have effects like a drug of abuse. Rats were given 25% glucose solution with chow for 12 h followed by 12 h of food deprivation each day. They doubled their glucose intake in 10 days and developed a pattern of excessive intake in the first hour of daily access. After 30(More)
Artifacts and surfaces that can display digital content are proliferating at a steady rate. Many of these displays will be peripheral, i.e., used for content that is not directly related to one's primary activities.

Most environments are <i>passive</i> -- deaf, dumb and blind, unaware of their inhabitants and unable to assist them in a meaningful way. However, with the advent of ubiquitous computing - ever smaller, cheaper and faster computational devices embedded in a growing variety of "smart" objects -- it is becoming increasingly possible to create <i>active</i>(More)
