Introduction to the Article

This article explores the benefits of using context awareness as input for adaptation in ultra-mobile devices. Context goes beyond just location and includes factors such as user social environment, physical conditions, and more. The article also discusses acquiring and detecting context using sensors, as well as the advantages of context awareness in ultra-mobile computing, such as adapting to environmental changes and improving user interfaces.

  1. Introduction to the Article Advantages of using context awareness as input for adaptation Context includes other factors than location Ultra-mobile devices Sensors for input Albrecht Schmidt, Michael Beigl, and Hans-W. Gellersen Telecooperation Office (TecO), University of Karlsruhe, Germany

  2. What Context is About User Social Environment Level Human Factors Task Flickering Light Wave-length Pressure and more… Conditions Physical Environment Acceleration Infrastructure Audio Location Temperature and more…

  3. A Working Model for Context A context describes a situation and the environment a device or user is in A context is identified by a unique name For each context a set of features is relevant For each relevant feature a range of values is determined (implicit or explicit) by the context

  4. Acquiring Context Explicitly – user gives input on the context (Sony Ericsson cell phone “flight mode”) Implicitly – monitoring of user and computer based activities (Cell phone automatic key lock)

  5. Sensors for Detecting Context for Ultra-Mobile Devices Optical/Vision Audio Motion Location Bio-Sensors Specialized sensors

  6. Sensor Fusion for Context Awareness To be able to adapt to situations rather than isolated physical conditions Combine sensor input for obtaining context awareness Sensor Fusion includes: Sensors Cues Contexts Scripting

  7. Advantages of Context Awareness in Ultra-Mobile Computing Adaptation to changes in the environment (Increase volume, car stereo) Improvement of user interface (Filter information flow, Volvo IDIS)

  8. Discussion/Questions Where would you really like to have context aware devices? Where would you really not like to have context aware devices? Do you think privacy will be a problem in the future, because of context aware devices? Do you think that context aware devices risk being factors of irritation, because they try to be to smart?
