New Trends in HCI

• Collaborative and communicative systems
  • Synchronous versus Asynchronous
  • Co-located versus remote
• Ubiquitous computing
  • Mobile systems
  • Embedded systems
  • Domain-situated systems
• Intelligent interfaces
  • Natural language interfaces
  • Recommendation systems
  • Software agents (e.g. "Clippy")
• Simulation and virtual reality

Discussion questions

• What are examples of different kinds of collaborative and communicative systems?
• Using the examples, what are the benefits of asynchronous systems? of synchronous systems?
• What are the principal obstacles to successfully developing and using natural language interfaces?
• What sources of information do recommendation system use? Where have they been useful?
• What is the tradeoff for systems whose interfaces change to fit user needs?
• Are there examples of useful software agents?
• Other than games, where have virtual reality systems been most useful? What level of fidelity is required?
