Title: Cross currents: water scarcity and sustainable CHI
Author: Tad Hirsch and Ken Anderson
Venue: CHI EA 2010

Summary:
In this paper, Hirsch and Anderson describe water conservation in New Mexico and how HCI can help in easing the process, as well as the word sustainability and the liquidity of its definition. The authors undertook a study in which they interviewed various inhabitants of the Albuquerque area about their water conservation habits and what they thought of legislative efforts.

Hirsch and Anderson discovered that many of them didn't conserve for monetary reasons, instead conserving for environmental reasons. In addition, some residents were unsatisfied with the current legislation, observing that big businesses got more water allocation than they did. Other residents were concerned about the lack of legislation on groundwater, which was being welled heavily and could cause sinkholes. All in all, they discovered that conservation and sustainability had many definitions just in the area, not to mention the changes it might have in other locales.

Discussion:
I found this paper interesting because, just like the last paper, I didn't really think of HCI having an influence in environmental matters like these. However, their research is important if only to discover better methods of conservation. Especially with regards to the welling of groundwater, if care isn't taken to preserve the water now, the consequences could be dire, since it could cause natural disasters like sinkholes, as well as increasing the damage from conditions like drought.

Microblogs #4 - Opening Skinner's Box

References:
Title: Opening Skinner's Box
Author: Lauren Slater
Venue: 2004

Chapter #1:
Summary:
In this chapter, Slater discusses the controversial work on B.F. Skinner. Skinner's work on the causes of behaviors was beneficial, but also extremely controversial. Slater discusses the man's work and life, and ultimately gives a much different picture of him than the one most people attribute to him.

Discussion:
This chapter was interesting because it illustrates how people can belittle someone whose beliefs are different than theirs. The controversy of his works has made his image look very negative, but when we dig deeper we can see how wrong that image is.


Chapter #2:
Summary:
In this chapter, Slater describes the a controversial experiment made by Stanley Milgram, and how its aftershocks are still felt today. She then talks about the results of the experiment as well as how those results were constantly debated. Finally, she mentions that the largest impact of the experiment might actually be on the people involved.

Discussion:
I found this chapter quite powerful because it made me wonder what I would do in the same situation. Additionally, seeing that the effects of the experiments were decidedly different between a man who was defiant versus one who complied was amazing, especially considering the compliant subject went on to really change his life.


Chapter #3:
Summary:
In this chapter, Slater describes the work of David Rosenhan, who through an experiment in the early 1970s, discredited the field of psychology. She describes how he and his compatriots got themselves admitted to psych wards, and how their success caused psychology to be diminished in status. Finally, she attempts the experiment herself today, and discovers that in some ways, the diagnosis has improved, and in others it still needs work.

Discussion:
I found this chapter interesting mainly because of how psychiatric facilities scare me. I cannot fathom trying to purposely get admitted to one, because I would be afraid of all of the drugs they might prescribe and their effects.


Chapter #4:
Summary:
In this chapter, Slater describes the works of Darley and Latane, who discovered some of the reasoning behind why people do not help in critical situations. They found that the pressures of social etiquette often overrode peoples' compulsions to help, especially in large groups. Slater then gives personal evidence for and against their theories.

Discussion:
I found this chapter interesting mainly because of its juxtaposition with the chapter in The Design of Everyday Things. Both books talk about how the bevy of evidence of normalcy combined with social pressure mean that we don't often don't mention problems until it's too late. Hopefully, like Slater mentions in this chapter, knowledge of this problem will arm me if I am ever in a similar situation.


Chapter #5:
Summary:
In this chapter, Slater discusses the work of Leon Festinger on Cognitive Dissonance. She discusses his theories and experiments and talks to someone who conflicts with that theory. She then mulls over the concepts of rationalization versus revision.

Discussion:
I actually wasn't a huge fan of this chapter. She has been doing a good job showing the balance between the theories we currently have and reality, but her examples are constantly getting more and more depressing. I might have to get a Prozac description if these get much worse.


Chapter #6:
Summary:
In this chapter, Slater describes the work of Harry Harlow and his experiments on primates and love. She goes through his early studies of touch to his later studies on depression. She then talks about the debate between what his experiments accomplished versus their cruelty to the monkeys.

Discussion:
This chapter was interesting because it showed a great debate between how much we can learn through animal testing as well as how awful it is on the animals. To be honest, I am and just as torn as the author is on the subject.


Chapter #7:
Summary:
In this chapter, Slater discusses the experiments of Bruce Alexander, who tried to disprove the chemical theory of addiction. She describes the "perfect" world of Rat Park and how its mice failed to stay addicted to the psychoactive substances they were given. Finally, she describes the ongoing debate between Alexander and others.

Discussion:
This chapter was interesting for a number of reasons. First, as addiction is such a buzzword in society, I found it interesting to hear some of the cases that try to disprove the current theories. Second, I like that Slater picked a less well-known paper for this one. Finally, I found the "perfect world" of the mice interesting because I wonder what we would feel like in such a place.


Chapter #8:
Summary:
In this chapter, Slater describes the work of Elizabeth Loftus, who showed that the memories we have can be modified by suggestion. Slater then describes the social effects of this work, which range from admiration by some and admonishment by others, dependent on whether they have ever had "repressed" memories brought back to the surface.

Discussion:
I found this chapter interesting because I had never heard of the repressed memory phenomenon. The fact that courts were using these shaky memories as sure evidence is shocking, and in a way I am glad that Loftus was there to try to help these people. On the other hand, believing that all memories are malleable would be difficult to live with in a similar way to atheism.


Chapter #8:
Summary:
In this chapter, Slater describes the work of Eric Kandel, who found the processes behind how human memory works. She gives the story behind how he found CREB, the chemical behind human memory, and how they are working today to find a medicine to enhance our memory. She then talks about whether or not it would be a good idea to enhance memory this way.

Discussion:
This chapter was interesting for a lot of reasons. First of all, the story about the guy who lost his long-term memory was sad, but the details behind how his life was afterwards was scientifically intriguing. After that, hearing about the work on medicine to enhance our memory was even better; the fact that they could also make a medicine to blank memory was interesting as well, if a bit scary.


Chapter #9:
Summary:
In this chapter, Slater describes the work of Antonio Moniz, who is the father of lobotomy. She describes his inspiration for the technique, its spread and popularity, and the modern techniques that are based on it today. She then follows the case of a man who has one done on him.

Discussion:
This chapter was interesting because it described the a procedure that seems to be reasonably safe, but one I definitely wouldn't be comfortable with. Having someone go in and cut at your brain doesn't really seem safe or good for you, even though it worked well for the example she gave.

Paper Reading #3 - Multi-lifespan Information System Design...

Comment 2

References:
Title: Multi-lifespan Information System Design in Post-Conflict Societies: An Evolving Project in Rwanda
Authors: Batya Friedman, Lisa P. Nathan, Milli Lake et al.
Venue: CHI EA 2010, April 10-15, 2010

Summary:
In this paper, the authors discuss how HCI can be applied to design healing mechanisms for post-conflict societies. The authors went to Rwanda, a country in which genocide occurred 15 years ago with the idea of designing a computer series that would help Rwandans not only cope with those terrible events, but also gain an appreciation for the efforts of the international courts prosecuting the people responsible for the massacre.

The authors asked organizations if they wanted to use this material and then observed what they did with it. From websites to seminars, these organizations found a positive use for the information.


Discussion:
I like what this study was intended to do. People who have gone through terrible events like these need a coping mechanism, and giving these people a positive way to deal with it is a positive step. However, I do wonder how effective these efforts will be. Even though there is no way to observe the long-term effects in the near future, I don't think that this mechanism will have a large effect on the situation in Rwanda.

Microblogs #3 - HCI Remixed

References:
Title: HCI Remixed
Author: Various Authors
Venue: Edited by Thomas Erickson and David W. McDonald; 2008

Chapter #1:
Summary:
In this chapter, William Buxton describes a music-making machine he used to use in 1971 and how strong the design was even today. The device's two-hand input scheme was simple enough for him to use despite the fact that he had never used it before, and he still believes it is one of the finest examples of HCI he has ever encountered.

Discussion:
I found this chapter interesting because of the machine's simplicity. The left hand note selector seems extremely simple to use and is a design I hadn't heard of before this article. Also, I liked this article because I found the wooden block "mouse" funny.


Chapter #4:
Summary:
In this chapter, Joseph A. Konstan talks about a 1961 input device called the Sketchpad and how the forward thinking of its maker, I. Sutherland, has kept the device relevant even today. Konstan describes the complexities of the hardware and the fine details of its software, and urges us to think ahead like Sutherland did.

Discussion:
I found this chapter interesting because I had never heard of this device before now. The fact that a man 50 years ago was able to envision a device that today is used by many graphics professionals is amazing, and it makes me hope to think as far ahead as Sutherland did.


Chapter #5:
Summary:
In this chapter, Wendy Ju describes Doug Englebart's demo of his NLS (oNLine System) and what it taught her about HCI and big ideas. She describes two different times during her education when viewing the demo showed her what was possible in the field of computing and also how sometimes big ideas go beyond just what you make at the time.

Discussion:
I found this chapter interesting because it shows not only how a great idea can be passed over as stupid or impossible only to be proven great later, but also that sometimes what we are remembered for might not be what we expect. The fact that Ju remembers the demo that Englebart gave over his invention is interesting and kind of cool.


Chapter #6:
Summary:
In this chapter, Henry Lieberman discusses a thesis by David Smith named "Pygmalion: A Creative Programming Environment" and how it applies to his life and to HCI. Lieberman discusses how this thesis gave him an inspiration in his efforts at making a child-friendly programming language. Then he discusses a list of lessons for people in HCI that they can take away from this paper.

Discussion:
I found this article interesting mainly because it mentions where the icon concept came from. The lessons to take away are equally valuable, but I tend to find the history more fun than the concepts in many of these essays.


Chapter #7:
Summary:
In this chapter, Sara Bly talks about the Xerox Red Book and how it set many important user interface concepts that are still used today. She begins by discussing the three main aspects of the book that had the biggest impact on her: UI specification, consistency, and desktop metaphor. She then goes into detail on each and discusses why these concepts are still important today.

Discussion:
This chapter is cool because it shows a story about how strong planning can lead to a better product. The designers of the Xerox Red Book thought thoroughly about the interface as they designed it, which led to a much more solid final product.


Chapter #9:
Summary:
In this chapter, Norbert Streitz discusses Mark Weiser's paper "The Computer for the 21st Century" and how it has had a large influence in the direction computing is going today. He begins the chapter by discussing the influences the paper had in his decision to create a digital wall workspace, as well as the influenced it had in HCI as a whole.

Discussion:
I found this chapter interesting because we discussed the "disappearing computer" concept multiple times in my freshman CS classes. Furthermore, by looking around today, I can see many instances where this design concept has actually come true.


Chapter #10:
Summary:
In this chapter, Anind K. Dey talks about the Active Badge System, an experiment that combined ubiquitous computing and location services in a way far before its time. Dey mentions how they started it as just a basic receptionist assistant, but as the users began to like it, a series of other applications was produced. Additionally, Dey discusses how their efforts to make the design feasible allowed them to test how it was used; this design feasibility is something that often isn't seen today.

Discussion:
I thought that this chapter was great because it showed a piece of technology that I would like to have now that was available years ago. While I don't like the idea of being tracked, having my computer desktop available automatically based on my location would be amazing.


Chapter #18:
Summary:
In this chapter, Saul Greenberg describes the research of John Tang, and how it affected not only the direction of his work on a virtual drawing space, but many other teams throughout the world. Tang's research redefined how important drawings were as opposed to other factors in the workplace; this research was applied by many later designers and led to much more fluid interfaces.

Discussion:
This chapter was interesting because it reinforced what I believe I am already learning is a big part of HCI: research on the target subjects. Tang spent a lot of time observing and quantifying his data, and its thoroughness led to a correct interpretation of that data and a much better user experience.


Chapter #20:
Summary:
In this chapter, Geraldine Fitzpatrick describes Schmidt and Bannon's paper on CSCW (Computer Supported Collaborative Work) and how the tenets they laid out for that new field can be applied to newer fields. Schmidt and Bannon took great care to define what is important for their field, and Fitzpatrick wants people in her field, ubiquitous computing, to take that same care in defining what is important in theirs.

Discussion:
I find this chapter interesting because again, like many of the previous chapters, the ideas laid out by computer scientists in the past are becoming relevant here today. Fitzpatrick's revisiting of her early days in what is now a strong field and how it reapplies today are something to keep in mind when we enter our respective industries.


Chapter #23:
Summary:
In this chapter, Brian Smith describes a paper by Hollan and Stornetta called "Beyond Being There," and how the idea of enhancing rather than replacing items in peoples' lives is the best way to design. Brian describes two items: a video conferencing program and a doll, and he shows through the story of his mother that even though the doll was simple, because it enhanced his mother's interactions with his daughter, it was the better product.

Discussion:
I find this chapter interesting because I never really thought that there was a difference between replacing items in peoples' lives and enhancing them. However, through the story, I can see how much better the less technical design that enhanced a person's life was than the more technical one that tried to replace a part of someone's life.

Chapter #24:
Summary:
In this chapter, Chris Schmandt discusses a study performed by John Gould on computer dictation software. He describes the methods and thoroughness of the study, and describes how it assisted the field. Finally, he talks about how the study's legacy isn't in today's dictation products, but in how his study was unable to pinpoint the best use for the software.

Discussion:
I found this chapter a big shift from the previous few in terms of the language and style. The chapter was much more focused on the scientific aspects of the paper. I found it interesting to hear the reasons why dictation software went from the next big thing to an unpopular technology.


Chapter #25:
Summary:
In this chapter, Steve Harrison describes a pair of artists, Kit Galloway and Sherrie Rabinowitz, and how a piece of art they created called the Hole in Space changed the way he thought on his research on video conferencing. The effect their art had -- engendering interest by strangeness -- was something that he couldn't forget about through his work on the project.

Discussion:
I found this chapter to be really cool because it shows how even something as abstract as art can have a serious impact on science. The inspiration that Kit and Sherrie's work had on Harrison changed the direction of his research in a direction he would probably never have thought otherwise.


Chapter #26:
Summary:
In this chapter, Scott Jenson describes an old design axiom by Edward Tufte, "1+1=3," and describes a real-life situation that best represents it. He observes the design of the open and close buttons of an elevator, and demonstrates that we can improve the design by making their functions more obvious. He then shows us not only that making the elevator have only an open button might improve it, but also makes us wonder why we were so vehement to have two buttons at all.

Discussion:
I find this chapter interesting because it piqued my thought process about why it is so difficult to remove a feature, even when it would make things easier to do so. I think it might have something to do with selling the product, in that we think having more stuff will bring more people and removing stuff will cause us to lose them.


Chapter #27:
Summary:
In this chapter, Jodi Forlizzi describes Muriel Cooper's paper, "Typographic Space," and how it inspired a field that is used in the media today. Her paper described the insights and problems that came from dealing with text from a moving viewpoint. These ideas became the basis for Kinetic Typography, a field that has since been used in movies and television.

Discussion:
This chapter was interesting because it demonstrated how a past work in the field of HCI has influences in a field that doesn't really involve computers at all.


Chapter #28:
Summary:
In this chapter, Steve Whittaker talks about a paper by Kidd called "The Marks Are on the Knowledge Worker." This paper describes how at the time the focus was on storing large amounts of information and how that focus isn't correct. Instead, programs should focus on helping the user make sense of the information. The author then indicates that even though Kidd was wrong about large information storage not being helpful, the need to make sense out of information is still important.

Discussion:
I found this chapter interesting because I never thought about how cluttered my e-mail inbox was nor how little I look into folders. I am now actually quite interested in how information might be stored in a different way to make it more accessible with ideas like tagging.


Chapter #34:
Summary:
In this chapter, Michael Muller describes Arthur Krupat's book, Ethnocriticism: Ethnography, History, Literature, and how it changed his idea of where he sat when it came to designing interfaces for users. Instead of observing himself as an extension of the development team, Muller changed his viewpoint to lying between the developers and the users, translating the users' wants and needs into something the developers can understand.

Discussion:
I like this chapter because it gives me a better idea of what HCI is about. Instead of focusing solely on the design from a hardware standpoint, HCI brings the focus on the prospective user base.


Chapter #46:
Summary:
In this chapter, Kate Ehrlich discusses the concept of mental models for computing given by Card, Moran, and Newell. Ehrlich talks about how even before the book containing these ideas was published, these concepts were the talk of the industry that would become HCI. Even though the GOMS (Goals, Operators, Methods, Selectional Rules) method would stop being the focus of HCI down the road, it still set the tenets of HCI.

Discussion:
I found this chapter interesting because it begins to bridge the gap of mental models that we have been reading in our other books and melds it with HCI. Even though this idea isn't the focus anymore, I actually like it better than the "look and feel" method that Ehrlich mentions in the chapter.


Chapter #47:
Summary:
In this chapter, Gary Olson describes Fitts's Law and how it made a large impact in the field of HCI. Olson mentions that the law was one of the first quantitative methods given to HCI, which up until that point had been largely qualitative. He then mentions a bunch of applications and papers that used this law to great effect.

Discussion:
I found this paper interesting because one of the papers that I read previously was about Fitts' Law and how it was not quantitative enough. This chapter showed me that despite that issue, having a formula such as this has been extremely helpful to the field despite the problems with the equation.

Paper Reading #2 - Edits & credits

Reference:
Title: Edits & Credits: Exploring Integration and Attribution in Online Creative Collaboration
Authors: Kurt Luther, Nicholas Diakopoulos, Amy Bruckman
Venue: CHI EA 2010, April 10-15, 2010

Summary:
In this paper, the authors describe how online collaborative works are put together, and how credit is given to the authors. They did this by interviewing 17 authors of collaborative works as well as what they call "cr-editors," or the leaders of these team projects, on a flash animation website named Newgrounds.

(Picture taken from Newgrounds Main Page)

What they discovered was that cr-editors had two main problems when making their collaborations: determining which works to include in a collaboration and deciding which authors should get the most credit. When it came to selecting authors' works, there were two main methods: selection by quality and a first-come first-serve method. Most cr-editors didn't have a favorite method; instead, they chose based on how high-quality they wanted their works to be. The first-come first-serve method often gave more prospective entries, while the quality selection method gave less entries, but the quality was better. When it came to giving credit to authors, cr-editors felt that the system made the process difficult. Newgrounds has multiple levels of authorship, with the highest only allowing a maximum of 10 people. Since only the highest level gives links to the author's page, it is a coveted position, and cr-editors found it difficult to choose who should go on it. However, the cr-editors liked Newgrounds' system better than others like Youtube, where only one collaborator can be listed.

Discussion:
I found this article interesting because I never knew that authorship of these online works was so competitive. I figured it was simple on these sites to give credit, and it saddens me to know that it is such a difficult process. I believe that the main fault of this paper is that while they point out the issues in the process, they do not provide a solution. Thus, I believe the first step to come after this paper should be positing a process by which collaborative works can be given credit quickly and painlessly.

Special Reading #2 - On Computers

Comments:
Comment 1
Comment 2

References:
Title: On Plants
Author: Aristotle
Venue: Edited by Jonathan Barnes; 1994

Summary:
In this paper, Aristotle argues that plants have souls in the same way that animals do. He does this by describing the great varieties in plants as there is in animals, as well as how plants grow and change during their lives like animals. He then talks about how animals are affected by the presence or absence of the elements, similar to animals. Finally, he describes how changes in location can change plants like they change animals.



Comments:
I found his argument interesting because it is made during the early days of science. Since they didn't have as much of an understanding of the processes of organic beings, they described them in terms of elements. Despite this, at the time, I believe his argument is reasonably sound. Since plants have the myriad variations that animals do, and since they respond to many stimuli like animals do, it is reasonable to assume that they would have souls like animals do, assuming you think souls exist, of course. Interestingly enough, since computers can respond from outside input and require outside elements to work, a case could be made for computers to have souls as well. However, after reading the Chinese Room paper, I am inclined to disagree.
