Using audio visualization, we seek to demonstrate how natural interaction is augmented with the addition of interaction history. Our Conversation Clock visualization captures and represents audio in a persistent and meaningful representation to provide social cues not available in an otherwise ephemeral conversation. In this paper we present user study(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)
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)
A social mirror is a specific type of visualization for group interaction. Three examples of social mirrors emphasize different motivations for visualizing vocal conversation: the power of visualization to influence conversation in real time, the addition of anonymous input into group visualization, and idea formation over time. Social visualizations are(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)
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)
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)
