School of Information Technologies Firestorm: a Brainstorming Application for Collaborative Group Work at Tabletops
نویسندگان
چکیده
The tabletop computer interface has the potential to support idea generation by a group using the brainstorming technique. This paper describes the design and implementation of a tabletop brainstorming system. To gain insights into its effectiveness, we conducted a user study which compared our system against a more conventional approach. We analysed the processes and results with the goal of gaining an understanding of the ways a tabletop brainstorming system can support the phases of this activity. We found that our tabletop interface facilitated the creation of more ideas and participants tended to create more categories. We observed that the tabletop provides a useful record of the group processes and this is valuable for reviewing how well a group followed recommended brainstorming processes. Our contributions are a new tabletop brainstorming system and insights into the nature of the benefits a tabletop affords for brainstorming and for capturing the processes employed by a group.

Dialogue, Knowledge Work and Tabletops: Lessons from Preservice Teacher Education
This pilot study is concerned with the exploration of tabletops in preservice teacher education, through the lens of sociocultural theories. An educational tabletop application designed to facilitate dialog and collaborative decision making, so called IdeasMapping, was enacted in the context of proposing a solution plan for a case study classroom problem. Students' responses to a questionnaire ...
متن کاملExploring the Potential of Tabletops for Collaborative Learning
Digital tabletops, with their multi-touch surfaces, are innovation that could provide new opportunities for learning. They could support rich interactive collaborative activities while maintaining natural face-to-face communication. Nevertheless, we still know little about the potential learning outcomes and the situations they favor. We have explored how group activities on tabletops could enc...
متن کاملTowards a Classroom Ecology of Devices: Interfaces for Collaborative Scripts
The ShareIT Project has been investigating how interactive tabletops can support co-located collaborative learning. As interactive tabletops are still in their infancy, basic questions of how these interfaces support collaboration are still unanswered. To address these, we have been conducting conventional psychology experiments, where a small intervention is run with a significant number of gr...
متن کاملDesigning OLMs for Reflection about Group Brainstorming at Interactive Tabletops
Brainstorming is a valuable and widely-used group technique to enhance creativity. Interactive tabletops have the potential to support brainstorming and, by exploiting learners’ trace data, they can provide Open Learner Models (OLMs) to support reflection on a brainstorming session. We describe our design of such OLMs to enable an individual to answer core questions: C1) how much did I contribu...
متن کاملFrom eSpace to coSpace: Integrating shared surfaces and physical spaces to support collaborative working
My research is concerned with how to facilitate fluid collaborative interactions in physical and digital spaces; by this, is meant the easy transition between (i) different activities at a surface, (ii) individual and group work, and (iii) display-based and external work. The goal is to design new forms of workspaces that enable different stakeholders (e.g., clients, agents, families) to engage...
