Book Reading #51 and 52 - Full Blog: Living With Complexity

Summary
Ch 1
In this chapter, the differences between complexity and complicated is described. Complexity is a state of mind but understandable but difficult. Complicated is confusing. Complexity can cause an artifact to be not as boring as a simple one.

Ch 2
The chapter discusses how complexity is all dependent on the situation and the individual. The idea of conceptual models are re-introduced.

Ch 3
This chapter discusses how the non trivial and simple things can actually complicate our lives. Examples of door locks and passwords are given to demonstrate the notion. They way technology is today however, we can't just have one password for all our information.

Ch 4
This chapter talks about social signifiers to serve as indicators to provide information to people. These are viewed as perceived affordances which can be impacted by culture



Discussion
These chapters were just reinforcements of what was already introduced in previous Norman books.

Book Reading #50 - Why We Make Mistakes

Summary:

Ch 12
This chapter talks about constraints and affordances. The chapter explains how combining these two can avoid many of the errors made by the users. It talks about the measures we must to take to avoid human errors.

Ch 13
This chapter talks about predicting the happiness one and others will feel preceding an event. He gives an example of how everyone wants to move to California because they think they will be happy though that is not always the case.

Conclusion:
This chapter summarizes the whole book. Main ideas of the book are discussed and touched on. He ties them all in to explain how easy it is for us to make mistakes and why we make them. The examples given help take a better look at our errors and possibly an opportunity to correct them.



Discussion:
I enjoyed this book. I liked the insight as to why people make mistakes and I could relate to some of them and understand the why behind it.

Book Reading #49 - Why We Make Mistakes

Ch 10
Summary:
This talked about optimism and depression and how it affected the view of reality. This causes people to overestimate or overlook things. This leads to overconfidence. Feedback of these views is also really important, The harder the task, the more confident people get because of the amount of information they have because of the complexity.

Ch 11
Summary:
This chapter discusses how professionals think they are good or bad at things. Expertise in something comes with practice, early start, and knowledge database in the brain. People don't like to do this though. No one ever reads the manuals to put things together. They also do it the first way the learned something. Thinking outside the box is key although we don't like to do so.



Discussion:
I enjoyed reading about the way people learn things and how they actually do things. I have caught myself being stubborn and doing it the first way I learned without accepting other methods until i failed.

Book Reading #48 - Media Equation

Full Blog

Part 1 Microblog

Summary:
Users sometimes tend to view computers as having human characteristics. Software programs that use a male voice in the program are viewed to be more assertive than programs with female voices. On the other hand, the software with female voices are viewed as more informative to the users. Although we know they are just simply machines, we do not always regard them as such.

Discussion:
A montage of Hollywood movies depicting AI came to mind when reading this. I find it amusing how people, at least in the movies, can get so attached to a computer and begin thinking it is real. I have not found myself thinking this. This could be because I am a computer scientist and understand the computer a bit better than others. It is easy to break away any ties and just see it as a tool.



Part 2 Microblog

Summary:
Research was conducted to see if humans interacted with computers in ways they would normally interact with other humans. People tend to be polite when describing a computer and its functionality. The voice used by the software also played a role in the interaction and how the users felt as described in the previous part, male voices were more assertive while female ones were warmer and more informational.

Discussion:
I find it hard to see how people can get so attached to computers and treat them as people as well. I just see them as a tool to get my homework and assignments done.




Part 3 Microblog

Summary:
This study dealt with seeing if users would be submissive or dominant with a computer. The dominant computer had stronger language and went first in interactions making it seem more dominant to the users. The other was used less language and went second in the interactions. Users perceived this computer as submissive.

Book Reading #47 - Why We Make Mistakes

Summary:
Ch 8
The idea of tidiness is discussed in this chapter. In order to understand something better, it must be rational, tidy, and/or simple. In our heads we straighten things out and make simple rules to keep our information tidy.

Ch 9
Men and women behave differently. This is because men tend to be overconfident in their actions. This leads to risk taking. One reason for this may be that as children, men are given more freedom to wander than women.



Discussion:
I think its interesting to have an explanation on why the difference in the sexes may be. Thinking about it, I do like taking risks and tinkering where I notice women are less likely to.

Book Reading #46 - Why We Make Mistakes

Summary:

Ch 6
This chapter discusses frames and anchors.  The framing of min as discussed in the book, is directly influenced by the person's environment, the risks involved in the particular decision that must be made, and by events and the timing of those events. In studies, people, when asked to decide over an issue, will usually anchor their responses to a numerical value, and even more so if it is the first one given.

Ch 7
This chapter deals with what I have done for a great number of the readings, skim. It discusses how people learn to skim through a great deal of things such as text and even images. When a person becomes familiar with that object, their focus loses grip and do not pay as much attention to detail.



Discussion:
These chapters were really interesting especially the chapter discussing skimming because I tend to do that a lot. I think that is why it is so hard to pick out flaws in your work because you become so familiar with them that you do not pay as much attention to detail and may miss things. Now add the rose-colored glasses effect on that, and it will be impossible to find any mistakes in your work.

Book Reading #45 - Things That Make Us Smart

Ch 3
This chapter talks about how we use cognitive artifacts to summarize the world. He makes the distinction between the real world and the artifacts we use to symbolize and represent that real world. Examples of such things are reading, writting, and mathematics.

Ch 4
In this chapter, Normas discusses the concepts of suface and internal representation. Surface representation is what is clearly visable to us on the surface. Internal is what we can  not see, what happens in the background. The concept of affordance also resurfaces.



Discussion:
This was an intersting read. The representation and writting was what seemed the most intersting to me. It made me think of how mankind has made up these symbols to represent real world objects to communicate. Also made me think of the variation in languages and modes of communicating.

Project Proposals

Final Project Proposal Paragraph




Group Members:

Stephen Morrow

Jorge Perez

Miguel Cardenas


For our final project, we will be implementing the system that we design in project 3 (our ethnography system). The system will be a companion to patrons going to the movie theatre. It will allow them to find theatres, view show times, purchase tickets, share activity on facebook, and discuss each movie after it is over with other users. The main goal of our system will be ticket purchasing. This will allow the user to simply scan a barcode for entrance into the movie (via an electronic turnstyle) instead of waiting in line to purchase a ticket, and then wait in line again to have their ticket torn by the attendant. The motivation behind this idea is to allow the user to have a much easier method to purchase tickets electronically, as well as be able to apply student and senior discounts to the purchase. Existing electronic ticket purchase systems require users to still wait in line to pick up their ticket, as well as charge them a convenience fee. We will implement this using a mobile-friendly website to ensure cross platform compatibility, as well as allow printing of the barcode for user’s without smart phones. To verify student discount eligibility, the system will require the user to create an account and link that account to their .edu email address.

Ethnography Results Week 8


I went to the movies on a Friday night to see Limitless. I was unable to get their earlier and the showing was at 11:00pm. There was not too large of a crowd at the time. My guess is most were at Northgate. I noticed mostly small group of friends at the movies but not too many of them. When I actually was in the theater, watching the trailers, that's when there was a giant influx of people coming in. It seems a lot of people came in late that night for some reason. After the movie ended, most people seemed to walk directly to their cars. I notice the later at night it is, the less likely people are to stay and chat. It could also be that they want to get to Northgate before it closes.

Book Reading #44 - Why We Make Mistakes

Chapter 4
Summary:
This chapter discussed the filter we put on the view of things to make it look better on or for us. This is done subconsciously and not intentionally. The mind naturally is biased in things we observe. Knowing outcomes of events also affect our biased way of remembering events.  Other things such as stereotypes and/or conflict of interest also affect our skewed view of events.

Chapter 5
Summary:
This chapter discusses multitasking and how it could lead to errors. This chapter makes the claim that the mind cannot divide itself to fully do more than one task. It claims we are able to jump back and forth from one task to another but never really fully devote our minds to two things at once.



Discussion:
I agree with chapter 4 in that people like to paint a pretty picture of their life around them. I have heard the notion of depressive realism that states that people with slight or moderate depression have a better and more accurate perception of reality. They are less likely to be affected by positive illusions or bias. I am not to sure on what to think about chapter 5. I think I can multi-task but there is no way of knowing if i really am, or just juggling two things back and forth.

Book Reading #43 - Things That Make Us Smart

Chapter 1
Summary:
With the huge rise in technology, it is helping our world an easier place to live by freeing up our time. This is done by automating repetitive tasks so that we may focus at more important complex tasks. This automation, although helpful, also has the potential to make us dumb. An example that comes to mind is being dependent and using a calculator so much that when it comes to easy math without a calculator, you take a bit.

Chapter 2
Summary:
There are many different methods and ways in which we learn. The different cognition that exist within this learning are experimental and reflection. In experimental, simple tasks get transformed into complex ones requiring more thought and problem solving. Reflection works by reflecting on an event or activity after it has happened to learn from it. There is also three different types of learning. One is accretion which is the sum of information. Tuning is another method that requires one to practice the task. Finally restructuring involves forming the correct conceptual models.



Discussion:
I agree with the first chapter as I sometimes find myself to dependent on technology that i need to use it in order to think. I also agree with the ways the different learning methods are described. I have found myself using different methods to learn or sometimes a combination.

Full BLog- Coming of Age in Samoa

 
 
Chapter 1
 This first chapter sets up the rest of the ethnography. It presents to us the work done on the study of adolescence in society. The rebellion and the changes exhibited by teenagers. Margaret Mead challenges these findings stating that the studies conducted on the subjects are not controlled. Many factors go into determining the behavior of an adolescent. She continues to argue that the only issue is not the controlled variables but the variables themselves, in this case, the environment established by society. Mead presents the dilemma that all studies are on American teenagers raised in an American society with an American way of thinking. She proposes the question of what would happen if we take the American society out of the picture and instead, conduct studies on adolescence in a small, secluded, culturally different setting. The location: Samoa. In describing the cultural differences between both civilizations (America and Samoa), Mead starts on her journey in Samoa to uncover the truth behind the complexity of humans. It becomes a classic question of nature vs. nurture.
 
Chapter 2
This chapter summarizes the day in the life of a Samoan Village. Mead describes the average day from dawn until past midnight where it all repeats again the next morning. She describes how the village starts stirring at dawn while villagers head out to the sea to freshen up and begin their daily tasks. The younger children are drowsy and hungry while the mothers make breakfast. Later in the afternoon, when the sun is beating down on them, they retreat to their homes and rest. The more daring children go for a swim under the shade. Once the sun begins to slowly sets, life comes back to the village as the people continue with their chores. As night falls, the mood becomes lighter as families gather in their homes to eat dinner and the children and elderly are tucked away. The village slowly settles to a few whispers as the night grows.
 
Chapter 3
This chapter dealt with the upbringing of children and the transcendence into adulthood for Samoans. The chapter discusses the big event that goes on at birth for high ranking children. Once the child is born, everyday life continues. The child is then mostly brought up by another child, usually 6 to 7 years of age. That older child is in charge of making sure the child doesn't do anything it is supposed, including crying. Boys help bring up children too, although they are usually relive of this duty in order to go help the older boys and learn to catch fish. This is how they learn the skill and grow into adulthood. Females continue to raise a child into their teens. This is when they are sometimes relieved of this duty, for the child they were raising is now raising another. The girls then go on to learn a skill or trait. They must learn in order to be competent and knowledgeable. This will help result in marriage.
 
 
Chapter 4
The chapter focuses on the household unit of Samoa. Mead explains about the matai and the different reigns they have over a household, which can range over a span of different houses. The rank of obedience is dictated by age, not time. The older being obeyed by the younger and where the matai  receives obedience from all under his household regardless of age. Taupo, princess of the household are chosen by chiefs to be adorned and emphasize the girl. Siblings being together is taboo. At about 9 or 10, the children are told to be separate and minimize interaction. It is not until old age that they may once again come together. Further detail is given about the relationships and ties people have such as those who you owe obligation. The matai are exempt from petty tasks in the household. Title, not birth is strictly observed.Rivalry also plays a big role in the hierarchy of status. Children, from the time they are small, slowly begin to creep in to the class system of the village.
 
Chapter 5
Until girls are about the age of 6, they have very little interactions with other children besides those in the household. At the age of 7, the children naturally begin to separate into groups according to their sex and this social stigma of intermingling with the opposite sex is enforced. The relationship in these groups was not strong. They play within the group and work at home. It is difficult for young girls when they have no girls around their age in their neighborhood to associate with. The relationships shift and change with age and sex status. The older girls continuously overlook a young girl's love life. Boys follow a simmilar situation when growing up paralleled by chiefdom and hunting tasks.
 
Chapter 6
This chapter explains the sexual experiences had by Samoans. A Samoan's first sexual experience is typically with someone older than them of the opposite sex. This is because of the taboo of men and women interacting with each other. Through continuous encounters, a marriage may arise from it. Adultery is frowned upon in the Samoan culture.
 
 
Chapter 7
The chapter discusses the different views on sex by the Samoan culture. Attitudes for the opposite sex is usually avoidance when they are small children. They do not interact. As they grow past puberty, this changes. There is the typical marriage route, in which a wife can never outrank her husband, Samoans take but there is also adultery and premarital affairs. Young couples usually seek out aid or some sort of ambassador. The chapter also discusses how a girl's virginity is treated much more like an accessory to add to attractiveness rather than a virtue. It not uncommon to see affairs outside marriage. 
 
Chapter 8
This chapter introduces us to dance in the Samoan culture and its importance and impact on the people. Dance crosses all age and ex groups. IT is what gives the villagers the ability to express themselves freely. Being a bad dancer may have some negative effect as other may look down on you.
 
Chapter 9
This chapter focuses on exploring the personalities and attitudes of Samoans. Once a Samoan is unwilling, it is left at that and not questioned. The word used for this is "musu". Another thing Mead notices is that when A Samoan describes a person, their description usually follows a pattern of sex, age, etc. It is almost like a cookie cut-out description where just one fills in the words for the person. A lot of times when asked question "I don't know" was the answer most of the time but Mead explains this is used to protect the little privacy they do have.
 
Chapter 10
This chapter dwells on the life and personality of the average Samoan girl. It mostly focuses on the average girl's individuality. Mead studies and gains insight on different girls and their personality and even mentions how death and other mature topics have intruded on their lives without the parents even protecting them or comforting them. It seems the average young Samoan girl must learn to mature early on. 
 
Chapter 11
The chapter mostly deals with girls who have broken away from the group for either one of two main reasons: they wish to have more freedom that is usually granted or are considered delinquents.  The chapter then goes into further detail with the recounts of several groups of girls that fall into one of those two categories. The main difference is the conflict that arises with their families if they are delinquents. 

Chapter 12
The chapter deals with the changes that occur in an adult male’s and female’s life. The 2 major changes observed were those that happen when people get married and when they get old. When people get married, they are not considered a household unit, but are still tied to their family households. With age, a man’s role is decreased while a woman’s increases due to her growing knowledge.
 
Chapter 13
This chapter discusses the many choices teens in our society have to make and what is expected of them. Young people have to decide whether to continue their education or if they will work or become a professional. Children begin moving out and start having choices and decisions about their life and sex life.

Chapter 14
The life of an American girl is viewed in this chapter from the view point of that girl. She tries to show the number of choices she must facing everyday life and what leads them to make decisions. She then proceeds to talk about education of these children and how parents should educate their children to face many choices.


Appendix III
This part deals with explaining how the Samoan culture has developed into what it is today. Samoans have takes all the simple parts of lives in developed countries and applied them to there own way of life. Changes in clothing, the household, and other areas have taken place. They still stay true to their roots though and depend heavily on the food they harvest. Many of them are Christian. Mead describes the influence as befitting the Samoans without any repercussions.

Summary:
This paper discusses the problem of having to design different user interfaces for different platforms for the same program. An example given is YouTube. THere is a seperate design for the web and telephone. The more variety of platforms, the more difficult it becomes to manually code the UI for the given program. Design tool Macros (D-Macs) is a multi-device GUI builder allowing designers to automate repetitive design actions. The main goal is to automate these transitions of UI from platform to platform in an appealing way. This tool allows developers to make a UI once and have it imported to other platforms.



Discussion:
I found this an interesting article. I think it would be nice to have a way to develop a UI for one platform and have it readily available in a pleasing way for another. This will also cut down on so much time of coding extra UI for different platforms. In today's world, people want to be able to use their services in a variety of platforms and this will help us achieve that.

Paper Reading #17 - Enhanced Area Cursors: Reducing Fine Pointing Demands

Reference Info:
Leah Findlater
UIST’10, October 3–6, 2010, New York, New York, USA
Summary:
This paper talked about different ways to aid those users who have impairments and difficulties using the conventional computer mouse. Two different methods werre discussed in the paper that would help users in this area: Click-and-Cross and Visual-Motor-Magnifier. The Visual-Motor-Magnifier enables user to enlarge area of click in order to better see and control their mouse. This allows for users to click on the intended button. This reduces the ammount of fine pointing. ursor size changes dynamically depending on the number of clickable targets in its surrounding. Another way of helping users is the Click-and-Cross method. This sllows users to click in an area and different clickable targets get seperated into arcs, constructing a circle. This allows for a user to easily point to an icon without having to deal with clutter.


Discussion:
I thought this was a great way to deal with the inabilty to click using the cursor. I would like to try this method out to see how intuitive and easy to work it is. It is interesting that they had two major methods of doing this in order to adjust to different users and their needs. I think I would like to try the Click-and_Cross method out of the two.
