    Exploring Video Streaming in Public Settings: Shared Geocaching Over Distance Using Mobile Video Chat
    (ACM, 2014) Procyk, J.; Neustaedter, C.; Pang, C.; Tang, A.; Judge, T. K.
    Our research explores the use of mobile video chat in public spaces by people participating in parallel experiences, where both a local and remote person are doing the same activity together at the same time. We prototyped a wearable video chat experience and had pairs of friends and family members participate in 'shared geocaching' over distance. Our results show that video streaming works best for navigation tasks but is more challenging to use for fine-grained searching tasks. Video streaming also creates a very intimate experience with a remote partner, but this can lead to distraction from the 'real world' and even safety concerns. Overall, privacy concerns with streaming from a public space were not typically an issue; however, people tended to rely on assumptions of what were acceptable. The implications are that designers should consider appropriate feedback, user disembodiment, and asymmetry when designing for parallel experiences.

    Sharing Domestic Life through Long-Term Video Connections
    (ACM, 2015-02) Neustaedter, C.; Pang, C.; Forghani, A.; Oduor, E.; Hillman, S.; Judge, T.; Massimi, M.; Greenberg, S.
    Video chat systems such as Skype, Google+ Hangouts, and FaceTime have been widely adopted by family members and friends to connect with one another over distance. We have conducted a corpus of studies that explore how various demographics make use of such video chat systems where this usage moves beyond the paradigm of conversational support to one in which aspects of everyday life are shared over long periods of time, sometimes in an almost passive manner. We describe and reflect on studies of long-distance couples, teenagers, and major life events, along with design research focused on new video communication systems--the Family Window, Family Portals, and Perch--that explicitly support "'lways-on video' for awareness and communication. Overall, our findings show that people highly value long-term video connections and have appropriated them in a number of different ways. Designers of future video communication systems need to consider: ways of supporting the sharing of everyday life, rather than just conversation; providing different design solutions for different locations and situations; providing appropriate audio control and feedback; and, supporting expressions of intimacy over distance.
