Assignment 4Type your name(s) here:Keisuke Nishimoto Briefly discuss the following issues for the paper that you have read: 1. what did you find 1.1. interesting about the article? The approach used to build the EDC is interesting to me. Many new systems proposed in HCI papers are developed mainly by bottom-up approach - at first there exist problems in some concrete tasks or existing applications, and then authors create a solution for that. In contrast, EDC was developed mainly by top-down approach, where theoretical challenges were first established based on existing researches and then a system was designed to answer these challenges. Of course these two approaches are not ambivalent and every system is developed by the mixture of both approaches, but the difference in its driving factor is notable. 1.2. not interesting about the article? The discussions in chapter "Challenging Problems for the Future of Human-Computer Interaction" is not easy to understand. I think that too many arguments were crammed into a small number of pages, resulting in few concrete examples necessary to explain proposed concepts. I also noted that there were not much explanation on the relationship among challenges proposed in this chapter. I admit that this is very personal and possibly trivial opinion from the academic point of view, but I feel that the naming of "Envisionment and Discovery Collaboratory" is too straight and explicatory to attract the attention of both academic and commercial fields. If one of the objectives of a research is to advocate new concept and thus affect the real world, it would be meaningful to put a fancy and catchy name on its research project. 2. what do you consider the main message of the article? The main message of this article as I understand is to encourage HCI community to tackle the challenge of how to create a system that enables all the stakeholders to actively take part in its design activity. Unfortunately, I cannot come up with an alternative name at this moment, though. 2. what do you consider the main message of the article? The main message of this article as I understand is to encourage HCI community to tackle the challenge of how to create a system that enables all the stakeholders to actively take part in its design activity. 3. are themes discussed in the article which you would like to know more about? Not all the problems proposed in the second chapter ("Challenging Problems for the Future of Human-Computer Interaction") were fully discussed in the following chapters. Particularly, the problem of motivation and rewards was not directly challenged in the development of the EDC, and I would like to explore the issue more, as an alternative metrics of UI evaluation to the traditional method of usability engineering (such as click count, time to complete a task etc.). 4. what did you find interesting about the “EDC” system? As I have already written, I am interested in the method to design the EDC system. Suppose the task discussed in the article is done in a classical analog method, such as bunch of large paper maps and color markers. Then, a system similar to EDC could be developed by the bottom-up approach, replacing papers and markers with a computer system. Then, a question of my interest is the benefit of EDC physical games compared with the system developed by the bottom-up approach. 5. do you know of other papers, ideas, and systems which are closely related to the article and the “EDC” system? Though it is more technology-oriented, the article "What Is Web 2.0?" proposes similar competencies required for Web 2.0, a next generation of web technology. Among them are:
6. what do the article and the associated system say about 6.1. design Design is a wicked problem in that the problem is seldom understood clearly and thus evolutionally discovered as the stakeholders learn about it. Design requires to synthesize knowledge from various problem domains and thus all the stakeholders should engage in the activity. 6.2. learning Since different knowledge and idea are distributed among the mind of every stakeholder, learning should be seen as collaborative knowledge construction to utilize and share them. As such, learning should happen on demand, in the context of activities. 6.3. collaboration Collaboration is necessitated by the process of design and learning, because the capacity of an individual mind is limited and each stakeholder may have different knowledge and skills, thus requiring to combine them in such activities. Externalization of individual mind is needed to encourage collaboration. 6.4. innovative media to support these activities? Creating such innovative media is an emerging theme of HCI. Evaluation of these system in real use scenario is necessary, because design, learning and collaboration themselves are evolutional long-term activities. 7. do you have any ideas how this research could / should be extended (based on your own knowledge and experience)? Even though physical gathering of people in one place is effective and sometimes necessary for good collaboration activities, it is not always possible due to cost, location and time constraints, especially when stakeholders are distributed around the world. In the future, the physical game of EDC may need to be extended to overcome such constraints and support distributed collaboration utilizing network technologies.
