Co-Interpreting Sensor Networks How can we design ubiquitous systems to integrate with our everyday lives and experiences? Phoebe Sengers Culturally Embedded Computing Group Cornell Information Science and Science & Technology Studies
1. A vision of ubicomp
What happens to intuitions, moods, whims, idiosyncrasies, … in a world where computers sense and act for us? Who is in charge? And how should we design to get good answers to these questions?
2. Inspiration from AI
Intelligence without representation 1. 2. 3. You don't need to know what's going on to act "smart. " Focus design on the dynamics of what's going on in the real world, not on what the computer "knows" or "doesn't know. " Design with the human in the loop.

Genghis meets ubicomp
It's not about intelligence
4. It's about co-interpretation.
Our approach Design ‘smart’ devices to only be smart in the presence of a human Privacy-preserving sensing (“shy” sensing; proxy measures; activity inferencing? ) Fault-tolerant user modeling Provoke user interpretation / reflection / activity

Target users : Fru’s House Fru describes herself as “Mrs. Average” She owns a large suburban style house in north London. She used to own a catering business, but now acts mostly as a housewife, except for some ‘business deals’ of an undisclosed nature.
A Very Full House A the moment, Fru shares the home with : Her husband (Zach)… An adult son (David)… A hip-hop producer on the dole (Ricky)… An aspiring glamour model (Wendy)… And four Italian exchange students.
An Extremely Social Environment Because of the large numbers of people who live and interact in this home, it tends to be an extremely social environment. Because of the large numbers of people who live and hang around at Fru’s, privacy and solitude are at a minimum. Still, Fru insists on at least one hour alone with Zach each day in the living room.
Possible Metrics Cheerful - How happy is the house? Tired - Are people getting enough rest? Social - Are people socializing in the house? Private - Are people getting enough alone time? Busy - Are people doing lots of things at home? Ordered - Is Fru’s house care routine up to par? Disordered - Is the house a shambles? Productive - Are people getting things done in their lives? Empty - Is the house less full than usual? Transitive - Are there lots of changes taking place in the home?
Sensor : Love Seat A sensor inside of the love seat in Fru’s room tell swhen it is being used. Zach has pleasant conversation with Fru while sitting in the love seat some mornings… a sign of cheerfulness in the home? Zach and Fru using the love seat in the afternoon could mean that they can’t have their alone time in the living room - a possible sign of disorder?
Attic Water Tank We monitor the water tank in the attic to look at the activity levels of the people in the house… Is the pattern of water use different than it usually is? The house might be a bit chaotic… Is more than the usual amount of water being used? The house might have even more people than usual in it… Are fewer showers than normal being taken? The house might be more empty than usual…
