Considerable human attention is expended on operating and attending to computers,
and humans are forced to spend precious time fighting technological artifacts rather
than doing what they enjoy and do well: human-human interaction and communication.
Instead of forcing people to pay attention to the artifact, that artifact should pay
attention to humans and their interaction. Rather than forcing humans to work within
a loop of computers, we would like to see computers serving in a Human Interaction
Loop (CHIL). A CHIL computing environment aims to radically change the
way we use computers. Rather than expecting a human to attend to technology,
CHIL attempts to develop computer assistants that attend to human activities, interactions,
and intentions. Instead of reacting only to explicit user requests, such
assistants proactively provide services by observing the implicit human request or
need, much like a personal butler would.
