This document contains lecture notes from an Information Architecture class discussing the concept of pervasive information architecture and ubiquitous computing. It describes how information and experiences are no longer confined to single channels or devices, but are mobile, cross-channel, and ubiquitous. Examples are given of how travel planning has changed from relying on travel agents and print materials to using online resources and GPS on mobile devices. Students are assigned a group project to assess the user experience of a system using specified methodologies.
