Leaves to users?<br /> We should account for biases like underestimation of errors<br /> humans filter out a lot from their successful working<br /> human activity very goal oriented<br /> &quot;there is no sense in which we can study cognition meaningfully divorced from the task contexts in which it finds itself in the world&quot;<br /> activity theory has a very funny squishy sense to it<br /> stimulus-response versus data or information processing?<br /> *how much context is needed?<br /> -- --<br /> distributed cognition: toward a new foundation for human computer interaction research 2000<br /> what is our top-level metaphor? City? Neighborhood? Building? House? Room?<br /> Social computing scares me, but maybe we need to consider it? <br /> Do we need anthropology?<br /> Nice set of four rules<br /> what is ethnographies: study of people working<br /> the token becomes a thing represented in many interfaces<br /> with search, some explicit organization is not needed <br /> affordances<br /> software/code visualization as an example<br /> examples of interfaces with computers are not compelling<br /> you space well<br /> hide things: iconify, unhide: proximity, needs trust in space-permanence<br /> use the world to perform otherwise difficult tasks</div>
