CoCo

Abstract

We present and discuss a fully-automated collaboration system, CoCo, that allows multiple participants to video chat and receive feedback through custom video conferencing software. After a conferencing session, a virtual feedback assistant provides insights on the conversation to participants. CoCo automatically pulls audial and visual data during conversations and analyzes the extracted streams for affective features, including smiles, engagement, attention, as well as speech overlap and turn-taking. We validated CoCo with 39 participants split into 10 groups. Participants played two back-to-back team-building games, Lost at Sea and Survival on the Moon, with the system providing feedback between the two. With feedback, we found a statistically significant change in balanced participation---that is, everyone spoke for an equal amount of time. There was also statistically significant improvement in participants' self-evaluations of conversational skills awareness, including how often they let others speak, as well as of teammates' conversational skills. The entire framework is available at https://github.com/ROC-HCI/CollaborationCoach_PostFeedback.

Emodash: A dashboard supporting retrospective awareness of emotions in online learning

“…The authors showed that mood self-tracking improves cohesion within teams, and leads managers to react proactively to changes in team members' moods (Rivera-Pelayo et al, 2017). Samrose et al (2017) also showed that providing teammates with post-session feedback on the group dynamics (including emotions) changes the way they participate.…”

Understanding the effect of a virtual moderator on people’s perception in remote discussion using social VR

“…(2) Enhance awareness of the least talkative person: Related work has shown that gaze, head, and body orientation are helpful social cues for managing turn-taking in multiparty conversation (Duncan, 1972;Kuzuoka et al, 2010). Furthermore, previous work has shown that visualizing every attendant's participation enhanced equal participation (Samrose et al, 2018). Based on these related works, we implemented the virtual moderator to orient its head and body toward the least talkative person to engage them in the discussion by encouraging them to take turns or reminding others to include them in the debate (Figure 1).…”

Developing Teams by Visualizing Their Communication Structures in Online Meetings

“…Samrose and colleagues evaluated ways of analyzing and visualizing online video communication [12]. As early as 2003, Anne Massey analyzed and visualized temporal patterns in global virtual project teams to explore "the nature of team interaction and the role of temporal coordination in asynchronously communicating GVPTs" [13].…”
