Pervasive computing (also called ubiquitous computing) is the growing trend



Sometimes I wander through the jungle of net (I love to say it is jungle as because you) and I get to encounter many unexplored things and being a UXM person my job is to layout a clear paths along the roads. Now, these new things, be it trends, services or whatever form it takes demand a logical explanation from me. Then I try to explain them with all my sincerity, mediocrity and with the help of little limited knowledge I gathered as in working as an Information Architect in the last few years and I leave them to the user to jump on a conclusion and give their verdict on them.    
Recently, in a similar occasion I heard the humming of this new trend Pervasive computing. The subject is in its infancy and certainly requires more impetus to be lighted among the front liners. Now I am trying to draw a basic inference based on my understanding of the subject, I don’t know how far justice would be made by that but as usually I am leaving them again to the audience court for verdict.  


Pervasive Computing:-
The words pervasive and ubiquitous mean "existing everywhere." Pervasive computing devices are completely connected and constantly available. An example of a practical application of pervasive computing is the replacement of old electric meters with smart meters. In the past, electric meters had to be manually read by a company representative. Smart meters report usage in real-time over the Internet.  They will also notify the power company when there is an outage, reset thermostats according to the  homeowner's directives, send messages to display units in the home and regulate the water heater.

SINGLE SEARCH

Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. In our example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you.
Web 3.0 browser will act like a personal assistant.

That's not all. Many of these experts believe that the Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like "where should I go for lunch?" Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants.

UBIQUITY
you’re writing an email to invite a friend to meet at a local San Francisco restaurant that neither of you has been to.  You’d like to include a map.  All you do mapping the address on a map site, searching for reviews on the restaurant on a search engine, and finally copying all links into the message being composed.  This is a familiar sequence of an awful lot of clicking, typing, searching, copying, and pasting in order to do a very simple task.  Therefore to avoid this you can use the help of technology called Ubiquity introduced by Mozilla fire fox. It lets you to map and insert maps anywhere ranslate on-page; search amazon, google, wikipedia, yahoo, youtube, etc.; digg and twitter; lookup and insert yelp review; get the weather; syntax highlight any code you find; and a lot more. Ubiquity “command list” to see them all.
