Presenters, such as analysts briefing to an executive committee, often use visualizations to convey information. In these cases, providing clear visual guidance is important to communicate key concepts without confusion. We explored visual cues that guide attention to a particular area of a visualization by 1) developing a visual cue taxonomy distinguishing internal from external cues, 2) designing a web tool based on the taxonomy, and 3) conducting a user study to understand user preferences in choosing visual cues.
Joint attention is the synchronizing of attention of two or more people. Lack of joint attention can be a warning sign for development delays, which can lead to early diagnosis and intervention. Our visualization highlights the quick glances of children that can be interpreted as bids for attention. This not only allow users to detect joint attention but also easily observe patterns by comparing the visualizations across a population of children.
In this work, we explored the landscape of music therapy and development of ways to overcome the challenges that lead to the underuse of music therapy. Contrary to the public perception that music therapy only addresses emotional needs, 47 out of 59 participants reported seeing improvements in other areas including behavioral, cognitive, linguistic, and social changes. We further found that the inaccessibility and the cost were major limitations surrounding music therapy adoption. Based on these results, we explore technological implications such as teletherapy and online information organization. .
We explored the language choice of multilingual Chinese and Korean students in the United States on Facebook. Results show that multilingual users use language for dividing and filtering their imagined audience. Culture played two contrasting roles; users wanted to share their culture in English but share their emotions in their native language. Through this work, we hope to portray language choice not as a tool for exclusion but of consideration for the audience and adherence to one's culture.
