Introduction to Ubiquitous Computing

• Ubiquitous computing is the method of enhancing
  computer use by making many computers available
  throughout the physical environment, but making
  them effectively invisible to the user

Ubicomp Projects
Classroom 2000

• Instrumented Classroom
• Captures different streams of information such as
  electronic annotations, audio, video, world wide
  web during a lecture

Common Features of Ubicomp Applications

• Transparent Interaction
• Remove physical interface between user and the
  work to be accomplished via the computer
• Examples freeform pen interaction, speech,
  tangible user interfaces, manipulation interfaces
• Context-Awareness
• Have information about the environment in which
  the application operates and react accordingly
• Automated Capture
• Capture everyday experiences and make record
  available for later use

13
Software Engineering Challenges

• Development Approach Outlined in Paper

Rapid Prototyping
User Evaluation
Final Application
14
Software Engineering Challenges

• Toolkit Design Issues
• Standardize support for transparent interaction
• Standard APIs
• Toolkit of commonly used context objects (TILE)
• Scalable interface

15
Software Engineering Challenges

• Software Structuring Issues

Application
Aggregator
Interpreter
Interpreter
Outdoor Sensor
Indoor Sensor
16
Software Engineering Challenges

• Component Integration
• Integration technologies not available on the
  range of devices and operating systems that are
  required
• Use of TCP, HTTP

17
Conclusion

• Strengths
• -Identifies key features of Ubicomp Applications
• -Uses real-life projects to throw light on
  Ubicomp Concepts
• -Thoroughly examines challenges of providing
  these features in the rapid prototyping model of
  research

18
Conclusion

• Weaknesses
• Focuses only on the rapid prototyping model
• Suggestions
• Focus on extensive study of the environment and
  users interaction with it
• Focus on evaluation tools and techniques in the
  early stages of products life cycle
• Observations
• Rapid Prototyping for Ubicomp Cost?
• Data Storage?
• Processing Power (for example, speech)
• Privacy and Security Concerns
• Social Issues - User Adaptability, Affordability
