Towards Smart User Models for Open Environments
... Information Technology in recent years has moved rapidly from single use, centralized
systems to distributed, multi purpose systems which are now increasingly embedded in a
fully interconnected world. Advances in both development and deployment are being made
through machine readable content (Semant ...
Out of Context - Media Lab Login
... Mathematical functions derive their power precisely from the fact that they ignore context, so
they are assumed to work correctly in all possible contexts. Context-free grammars, for
example, are simpler than context-sensitive grammars and so are preferable if they can be used to
describe a language ...
Individualised interaction with users
... User models are important because they represent information about the user so that a system can operate more
effectively. User modelling has been studied in many different communities such as: knowledge representation;
planning; natural language understanding and generation;
intelligent teaching sy ...
What Is AJAX?
... AJAX applications can benefit both the user and the developer. Web applications can
respond much more quickly to many types of user interaction and avoid repeatedly
sending unchanged information across the network. Also, because AJAX technologies

probabilities of his class. Therefore, the user class helps bias the agent initially towards this

Intelligent User Interfaces for Ubiquitous Computing
... User interfaces for computational devices can be challenging for both their users and their
designers. Even such simple things as VCRs or TV sets feature interfaces that many people
find too difficult to understand. Reviews and tests of consumer electronic devices very
often rank bad usability even ...

Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer.Usability includes methods of measuring usability, such as needs analysis and the study of the principles behind an object's perceived efficiency or elegance. In human-computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site (web usability) is designed. Usability differs from user satisfaction and user experience because usability also considers usefulness.
