6 Summary The idea illustrated in this paper is very straightforward and practical in real world applications. The author designed a system that can capture design history and help improve the efficiency of such design process. In short, it is a snapshot system that help users quickly locate their past design sessions. Specifically, users collaborate…

5 Summary In this paper, the author discuss group work outcome quality on wikipedia through coordination. Two categories of collaboration was defined: explicit coordination, the editors plan the article through communication, versus implicit coordination, which subset of editors structure the work by doing the majority of it. The author’s assumption is that, in coordination intensive…

8 Summary In the first paper, the author would like to study the problem of evaluating group brainstorming productivity and breadth. He proposed to observe the effect of internal diversity: cultural differences, and external diversity by supplying extra stimuli (pictures.) As for user study, two person groups were asked to perform 3 brainstorming tasks via…

4 WeBuild: Automatically Distributing Assembly Tasks Among Collocated Workers to Improve Coordination Summary In the first paper, the goal is to improve group efficiency and coordination. Specifically, participants was asked to complete manual assembly tasks, algorithm will assign subtasks to different collocated workers. They observed increased efficiency through reduction of startup time and overall time…

2 Summary In this paper, the author discussed introducing parallel prototyping during group creative design process and show better results compared to serial design. In traditional theories, parallel design have several benefits including: promotes comparison, encourages exploration, foster design confidence. The user study includes several key criterias, For example, the result can be measured objectively…

1 Summary In this paper, the author address the problem of analogy searching, which is effective when using one domain knowledge to solve problem in another domain, but this is difficult. The author designed 2 experiments, a set of 5 problems was defined and corresponding schemas was provided, then MTurks users was asked to find…

The authors of this paper are affiliated with the University of Washington. This paper was published in CHI during 2012. They provided a framework for listening, created a system that helped utilize this framework, and then they tested their system through a few different scenarios. I believe one major improvement to the system would be…
