Modern enterprises are replete with numerous online processes. Many must be performed frequently and are tedious, while others are done less frequently yet are complex or hard to remember. We present interviews with knowledge workers that reveal a need for mechanisms to automate the execution of and to share knowledge about these processes. In response, we(More)
A gap exists between the growing prevalence of peripheral displays and appropriate methods for their evaluation. Mankoff et al. [11] present one attempt to bridge this gap by adapting Nielsen's Heuristic evaluation to the defining characteristics and goals of peripheral displays. In this paper, we present a complementary approach that depends on active user(More)

this way of living has its toll. We humans are not machines, and we cannot be always on, 24/7. Few of us are able to escape living in the fast lane, and we envy those who choose a simpler life than ours, with a slower-paced job, fewer tasks, fewer worries, and more time on their hands. Why can't the rest of us? Where are we running to? Like a Hamster on a(More)
One of the goals of affective computing is to recognize human emotions. We present a system that learns to recognize emotions based on textual resources and test it on a large number of blog entries tagged with moods by their authors. We show how a machine-learning approach can be used to gain insight into the way writers convey and interpret their own(More)
