  1. Pervasive Computing:What Do Users Want? Elizabeth Royer University of California, Santa Barbara eroyer@alpha.ece.ucsb.edu

  2. Question: What do you think of when you hear the term ‘pervasive computing’? • an inevitable trend • feel excited and anxious • convenient access to relevant information • computing power in all kinds of devices, for all kinds of purposes • every device with a modicum of memory and a small microprocessor… all networked together • computers everywhere

  3. Question: How do you feel about the idea of computers in everything, all of which are networked together? • its cool, and there’s lots of potential in it • great concept. It makes the notion of the Jetsons much more a reality • excited by the possibilities • in some cases it could be unnecessarily expensive or extraneous, otherwise it seems really cool • apprehensive about the risks • not too good. The idea is loony and scary. • concerned about reliability

  4. Question: Which of the following would you use to describe your feelings towards pervasive computing? • Excited by technological challenges: 100% of techies • Excited by ability to control household items remotely: 92% • Excited by possibility of more easily networking personal devices: 75% • Excited by the potential availability of information: 75% • Concerned about privacy: 83% • Concerned about security: 83% • Too many devices: 42%

  5. Pervasive Computing: The idea that computers are embedded in everything, all of which are networked together. You will be able to adjust the setting of your home air conditioner before you leave work, check the integrity of your home security system while you are away, and seamlessly synchronize the data in your personal computing devices...

  6. Responses... • pervasive computing is great and will improve the quality of life • I would love this! • need a border line between usefulness and nonsense • I like it as long as the privacy and security issues are addressed • expensive

  7. Pervasive computing: The idea that computers are embedded in everything, all of which are networked together. When you are walking down the street, you will be able to receive menus from nearby restaurants, or advertisements from stores announcing sales. You will be able to walk into any office in your department, and your phone calls will be automatically transferred there by the location tracking system...

  8. Responses... • I like it as long as I have the ability to turn these features off • I’m not really sure I want to be that wired. It seems that we would have to be willing to forgo some of our personal privacy. • too much information. too little control. • this seems more intrusive. • that’s what I really need - more advertisements

  9. What can we learn from this?

  10. Users want... • Control • Reliability • Security

  11. How can we filter data so that the user is not bombarded with unnecessary and unwanted information? How can we build reliable systems and ensure they ‘do the right thing’ when it malfunctions? How can we incorporate security so that only the user can control his/her property?

  12. What does this mean? Ashby’s Law of Requisite Variety is precluded by the limits of such systems to make all information available with equal weight. Degrees of selection freedom are limited by the discretion/capacity of the apparti. That leaves the door open for ‘buying influence’ and unfunded or weakly funded entities ‘dying’ before having a chance to live or develop. It is a problematic issue, separate from the capacity to deliver such an information system.
