    OneSpace: Shared Depth-Corrected Video Interaction
    (2013) Ledo, D.; Aseniero, B. A.; Greenberg, S.; Tang, A.
    Video conferencing commonly employs a video portal met-aphor to connect individuals from remote spaces. In this work, we explore an alternate metaphor, a shared depth-mirror, where video images of two spaces are fused into a single shared, depth-corrected video space. We realize this metaphor in OneSpace, where the space respects virtual spatial relationships between people and objects as if all parties were looking at a mirror together. We report prelim-inary observations of OneSpace's use, noting that it encour-ages cross-site, full-body interactions, and that participants employed the depth cues in their interactions. Based on these observations, we argue that the depth mirror offers new opportunities for shared video interaction in the form of a shared stage.

    STRATOS: Using Visualization to Support Decisions in Strategic Software Release Planning
    (ACM, 2015) Aseniero, B. A.; Wun, T.; Ledo, D.; Ruhe, G.; Tang, A.; Carpendale, S.
    Software is typically developed incrementally and released in stages. Planning these releases involves deciding which features of the system should be implemented for each release. This is a complex planning process involving numerous trade-offs-constraints and factors that often make decisions difficult. Since the success of a product depends on this plan, it is important to understand the trade-offs between different release plans in order to make an informed choice. We present STRATOS, a tool that simultaneously visualizes several software release plans. The visualization shows several attributes about each plan that are important to planners. Multiple plans are shown in a single layout to help planners find and understand the trade-offs between alternative plans. We evaluated our tool via a qualitative study and found that STRATOS enables a range of decision-making processes, helping participants decide on which plan is most optimal.
