Summary
Henry Lieberman talks about his experience with Pygmalion and its effect on computer science. Developed by D.C. Smith, Pygmalion is a programming tool that introduced the notion of programming visually with icons and examples. However the program is more valuable because it taught the author several lessons involving the encouragement of conducting research in the HCI field.
Discussion
The reading was somewhat interesting. I wished I had seen more demonstrations on the type of things PBE can achieve. However, I thought it was cool that D.C Smith worked on the Xerox Star project which was one of the first graphical operating systems of the time.

Chapter 7: Fundamentals in HCI: Learning the Value of Consistency and User Model
Summary
Sara Bly discusses the impact of the Xerox Red Book in the HCI community. This book was the functional specification that described the user interface for the Xerox Star Workstation. Originally (more formally rather) called the Star Functional Specification, the book had three fundamental aspects that were very important to the author: User interface specification, consistency, and the desktop metaphor. These aspects were fundamental to the HCI basis of the author.

Discussion
I didn't find this chapter particularly interesting since it wasn't very specific. I appreciate the author's opinion about the Xerox Red Book, however, I don't think it had much of a message. That may be because in today's HCI most people take user interfaces for granted.
Chapter 9: The Disappearing Computer
Summary
In the "disappearing computer" Streitz discusses the work of M. Weiser. The author analyzes different paradigms that allow computers to become invisible to the user. The computer disappearance can be physical (involving miniaturization of devices), or mental (where users see computers as a mean instead of a device). Streitz also discusses smart environments and their meaning to the users.

Discussion
Very interesting chapter. It provided an interesting point of view about ubiquitous computing and smart environments.Chapter 10: It Really Is All About Location!
Summary
This chapter is a continuation of the disappearing computer concept. While the idea of ubiquitous computing was explored in chapter 9, Anind Dey discusses an implementation and technological implications ubiquitous computing. Dey talks about a paper written by Want (et. al) where the concept of indoor tracking was implemented using location badges worn by employees. Not only did Dey discussed some implementation issues about the system, but he also talked about other aspects involving employee's willingness to embrace the system.Discussion
I was really concerned about privacy issues concerning an indoor tracking system. However, from what I read in this paper, employees liked the system and the benefits it provided. Chapter 46: The Essential Role of Mental Models in HCI: Card, Moran, and Newell
Summary
Kate Ehrlich discusses the impact of mental models on the development of HCI. Not only do mental models provide an abstract representation of how the mind works, but in HCI it takes the form of several concepts such as the model of the system, the engineer's model of the system that drives design decisions, the UI model of the system, and the user's model of the system. The author quotes the work of Card et al. where they design the GOMS model to explain and predict the interaction between humans and computer. This model was not only theoretical by it was also testable.

I didn't find this chapter particularly interesting, except for the fact that it provides a historical perspective on the HCI field and the disagreement in the forces that drive it.
Chapter 47: A Most Fitting Law

Chapter 47: A Most Fitting Law
Summary
This chapter is about the law devised by P. M. Fitts while he was in the military. This law takes the form of a formula that calculates movement time taking while taking into account the distance and size of the target. The author, Gary Olson, gives a few examples where the law has been used to design interface paradigms and also discusses some of the limitations of the law.

Very interesting chapter about HCI that shows how this field is not only composed of qualitative data. HCI, as the author expresses, is a combination of several fields and different types of analysis.
