What is an Interactive System (IS) ?
user interaction system
perception
action(s)
IS := {IS*, Human, ICT component, [additional component]}

What are the technical challenges?
• New interaction styles– speech input/output– computer vision based input (e.g., gestures)– audio interfaces (e.g., non-speech audio)– tactile and force feedback
• New interface concepts– adaptive and intelligent software– natural user interfaces

Trends in User Interface Technology
Ubiquitous and Mobile computing Ambient rooms and Cooperative buildings

• Perception Space– The physical space where
the user’s attention is.
• Action Space– The physical space where
the user acts in.
• Design Principle:– perception space and action
space must coincide!

Airline Applications
• This remarkable ultra-lightweight computer, worn as a belt, delivers maximum information to users with a minimum of work.
• Designed for individuals who demand mobility, this computer offers voice control and heads up display for complete, hands-free operation.
• Users can enter or retrieve information while going about their jobs, instead of constantly returning to the shop area to check a stationary computer, or stopping work to punch keys.

Head-up Displays in Cars
• More information and less distractionInformation on the state of the road, on the speed of the vehicle in front (supplied by the intelligent cruise control), on obstacles lying around the next bend in the road identified by the remote detection system, or direction arrows sent by the driver guidance system... drivers will be receiving more and more information from "intelligent" vehicle systems.

Natural User Interfaces (NUI)
No technical equipment inside the body space of the user!
2. design principle
