             One of the major advantages of using a system such as InfoPad would be that much of the data could be realtime, which requires an application system that allows for processes and data to "come to" a terminal without requiring any other software on the terminal ahead of time. Thus, much of the research involves application migration, and coordinating system status with remote servers.
             The issues for user interfaces include making the best of a limited display size, the usage of pens as a form of user data input, and especially, the use of handwriting recognition and speech recognition as forms of user data input.
             Here is a diagram, taken from the web, that outlines the scope of the research being done for the InfoPad project:
             One of the most interesting ideas in ubiquitous computing is the concept of "smart matter", sometimes known by its more formal name, Microelectromechanical Systems. The idea is nothi
