Summary
In this chapter, the author William Buxton tells the story of one of the most influential HCI designs: a two handed user interface. This primitive interface controlled the SEL 840A computer that was used to compose synthetic music. The real purpose behind the system, however, was not to provide a music composing machine but to study the human computer interactions between the machine and the musicians that used it.
Discussion
The article had many interesting ideas and principles that are still in use today. The fact that the machine was built from the ground up with non-technical users in mind really impressed me, as well as the reason behind the construction of the machine. The machine was built to study HCI.
Chapter 4: Drawing on SketchPad: Reflections on Computer Science and HCI
Summary
Joseph A. Konstan discusses in this chapter the importance of HCI as it pertains to computer science. By discussing the implementation of one of the earliest drawing systems, the author is able to describe the relationship that exists between HCI and computer scientist. The author believes that HCI is a force that drives computer science forward while the field benefits from the discoveries made by computers scientist. This relationship is of mutual interest.
Discussion
Aside from the description of Southerland's SketchPad system, which was very interesting, this paper discussed a topic that relates somewhat to the research paper reading assigned (paper reading #2). Both topics discuss the need and importance of HCI relating computer science. In the assigned reading, the driving force was fed by the desire to better respond to the need of older adults, whereas in this paper, Konstan talks about the fact that the first HCI researches focused on easy-to-use computer interfaces.
Chapter 5: The Mouse, the Demo, and the Big Idea
Summary
This chapter discusses Douglas Engelbart's big idea: the computer mouse. While the discussion of this invention touches upon the implications of the discovery, most of the author's description is targeted toward the fact that the mouse was actually designed to augment human intellect. However, the author states that people who watched Engelbart's presentation came away with the feeling of having seen an amazing presentation.

Discussion
I got to read about one of the most important discoveries in HCI. The most interesting aspect about this chapter is noticing how the mouse has not basically changed from its primitive form; which makes me wonder if it will ever be replaced (partially or completely) by another technology.

Chapter 18: Observing Collaboration: Group-Centered Design
Summary
Saul Greensber talks about the development of group-centered design in the late 1980s. He discusses the works of John Tang at Xerox PARC and its significance to current group-centered implementations. In this essay, the author states that the importance of Tang's work was the foundations it laid on human factors that affect visual workspaces, but most importantly the methodology with which it was designed; that is; the fact that observation of actual working practices plays a huge role in group-centered designs and development.
Discussion
This article makes emphasis on the fact that group-centered designs must be observed in order to understand the demand of the users. It turns out that group interactions are equally as important (if not more) as the individual one when designing groupware.

Chapter 20: Taking Articulation Work Seriously
Summary
The author discusses the works of K. Schmidt and L. Bannon relating Computer Supported Cooperative Work. In their paper Schmidt and Bannon describe CSCW as "an endevour to understand the nature and requirements of cooperative work. As the author describes in this essay, Their work provided a conceptual framework that produced interests in other research directions. This so called framework highlights the fact that groupware assumes mutual dependence among participants.

Discussion
If I understand correctly, this article talks about the importance of groupware and the framework where users can collaborate. It also states that this framework is essential and is a requirement for activities that involve interaction with several members of a group.Chapter 23: Video, Toys, and Beyond Being There
Summary
Video, toys, and beyonde being there talks about face to face communication enhancements as discussed by J. Hollan and S. Stornetta. I thins paper, the author compares the computer communication enhancements to shoes and crutches. Shoes are worn permanent; whereas crutches are temporary. With such analogy in minde, the authors sets out to discover how face to face communication can be enhanced to the point where they are not replacing the aformentioned trend, but rather enhancing it. For example, the author describes how webcam communication over the internet is a replacemente for face to face communication, but when the two people meet, the participants in the face to face conversation interact by means of other objects to the point that it is called "beyond" being there (face to face).

Discussion
The importance of this paper is that it looks to revolutionize face to face communication instead of evolutionize it. It was very intersting hearing the author talked about Lilly the doll, and how this object was able to bring grandma and grandaughter closer than they would with other traditional face to face interactions.
