Conversation Clusters explores the use of visualization to highlight salient moments of live conversation while archiving a meeting. Cheaper storage and easy access to recording devices allows extensive archival. However, as the size of the archive grows, retrieving the desired moments becomes increasingly difficult. We approach this problem from a(More)
Aural conversation is ephemeral by nature. The interaction history of conversation fades as the present moment demands the attention of participants. In this paper, we explore the nature of group interaction by augmenting aural conversation with a persistent visualization of audio input. This visualization, Conversation Clock, displays individual(More)
Isochords is a visualization of music that aids in the classification of musical structure. The Isochords visualization highlights the consonant intervals between notes and common chords in music. It conveys information about interval quality, chord quality, and the chord progression synchronously during playback of digital music. Isochords offers listeners(More)
Inspiring and maintaining student participation in large classes can be a difficult task. Students benefit from an active experience as it helps them better understand the course material. However, it's easy to stay silent. Opportunities to participate in conversation allow students to question and learn. The Fragmented Social Mirror (FSM) provides students(More)
In face-to-face group situations, social pressure and organizational hierarchy relegate the less outspoken to silence, often resulting in fewer voices, fewer ideas, and groupthink. However, in mediated interaction like email, more people join in the discussion to offer their opinion. With this work, we aim to combine the benefits of mediated communication(More)
In the last decade, blogs have exploded in number, popularity and scope. However, many commentators and researchers speculate that blogs isolate readers in echo chambers, cutting them off from dissenting opinions. Our empirical paper tests this hypothesis. Using a hand-coded sample of over 1,000 comments from 33 of the world's top blogs, we find that(More)

In this work we describe Conversation Votes, a visualization to create new backchannels in conversation and augment collocated interaction. We expand the idea of a social mirror, a reflection of interaction, to incorporate direct user feedback in the form of anonymous voting. By capturing user input, the mirror becomes more demonstrative of context as(More)
