- Exploring and Evaluating the Potential of 2D Computational NotebooksHarden, Jesse (ACM, 2023-11-05)Computational notebooks are popular tools for data science and presentation of computational narratives. However, their 1D structure introduces and exacerbates user issues, such as messiness, tedious navigation, inefficient use of large screen space, performance of non-linear analyses, and presentation of non-linear narratives. In this Ph.D., we address these issues through the design, exploration, and evaluation of computational notebooks which use 2D space to organize cells, or 2D computational notebooks. Specifically, we explore whether users would use 2D space, design and evaluate a 2D computational notebook prototype for individual work, explore how users collaborate in 2D space for data science and education, create and validate a theoretical understanding of how nonlinear processes in data science cause problems when forced into a linear, 1D computational notebook, and build upon the foundation we have made to refine 2D computational notebooks. Our work contributes insights on if and how expanded space usage can improve computational notebooks.
- SAGE3 for Interactive Collaborative Visualization, Analysis, and StorytellingHarden, Jesse; Kirshenbaum, Nurit; Tabalba Jr., Roderick S.; Leigh, Jason; Renambot, Luc; North, Chris (ACM, 2023-11-05)SAGE3, the newest and most advanced generation of the Smart Amplified Group Environment, is an open-source software designed to facilitate collaboration among scientists, researchers, students, and professionals across various fields. This tutorial aims to introduce attendees to the capabilities of SAGE3, demonstrating its ability to enhance collaboration and productivity in diverse settings, from co-located office collaboration to remote collaboration to both at once, with diverse displays, from personal laptops to large-scale display walls. Participants will learn how to effectively use SAGE3 for brainstorming, data analysis, and presentation purposes, as well as installation of private collaboration servers and development of custom applications.
- Traces of Time through Space: Advantages of Creating Complex Canvases in Collaborative MeetingsKirshenbaum, Nurit; Davidson, Kylie; Harden, Jesse; North, Christopher L.; Kobayashi, Dylan; Theriot, Ryan; Tabalba, Roderick; Rogers, Michael; Belcaid, Mahdi; Burks, Andrew; Bharadwaj, Krishna; Renambot, Luc; Johnson, Andrew; Long, Lance; Leigh, Jason (ACM, 2021-11-05)Technology have long been a partner of workplace meeting facilitation. The recent outbreak of COVID-19 and the cautionary measures to reduce its spread have made it more prevalent than ever before in the form of online-meetings. In this paper, we recount our experiences during weekly meetings in three modalities: using SAGE2 - a collaborative sharing software designed for large displays - for co-located meetings, using a conventional projector for co-located meetings, and using the Zoom video-conferencing tool for distributed meetings. We view these meetings through the lens of effective meeting attributes and share ethnographic observations and attitudinal survey conducted in our research lab. We discuss patterns of content sharing, either sequential, parallel, or semi-parallel, and the potential advantages of creating complex canvases of content. We see how the SAGE2 tool affords parallel content sharing to create complex canvases, which represent queues of ideas and contributions (past, present, and future) using the space on a large display to suggest the progression of time through the meeting.
