Connecting objects to information in the real world, in real time An agent-based approach

What is WRONG with the existing Web?

WRONG Modality:  Blind users cannot read textual descriptions.  Automatic text-to-speech interfaces may be able to verbally convey the textual contents of a Web page to users, but if the Web page is formatted for visual access the sequential information access may become unintelligible or inefficient.

WRONG Language:  Crucial explanatory text may be provided in the wrong language. For instance less than 15% of U.S. Web sites contain Spanish translations

WRONG Nomenclature:  Information may be expressed in an unfamiliar measurement system. The translation of Celsius to Fahrenheit or kilometers to miles, while scientifically trivial, may represent a serious impediment for many users

WRONG Time:  The information may be correct, relevant and readable, but might be presented at the wrong time. Stock information, for instance, is most useful when presented in real-time.

WRONG Format:  Information can look great on a large computer monitor, but be completely unsuitable for small information devices such as PDAs and cell phones.

Use End-User Programmable Agents to Bridge the Gap between Existing and Relevant Information on the Web

What happens when we enable agents to access Web pages and merge the notions of browsers and simulations?

The Syntactic Web The Semantic Web The Pragmatic Web

 The vision of the Pragmatic Web is about the end-user controlled processing of all- purpose Web-based information into information of practical consequences to individuals.

Boulder Live The browserless agent-based Web

Why?  Make information accessible to disabled, e.g., blind or motor skill challenged  Have agents access information user controlled, e.g. voice commands, or autonomously  Have agents synthesize new information  Create information processing ecologies: make agents sharable goods ( , Web).  Access information on small wireless devices including PDAs and cell phones

Bridge…  Modalities: e.g., text speech  Time: get information only WHEN it is relevant  Nomenclature: e.g., Fahrenheit Celsius  Languages: English, Spanish, German, …
