In Search of Design Excellence

Rutter, G. B. (2010). “In Search of Design Excellence.” http://www.appliancedesign.com. Visited on October 15th, 2012: http://www.appliancedesign.com/Articles/Feature_Article/BNP_GUID_9-5-2006_A_10000000000000931808 Design excellence can be defined as a combination of design excellence, or the fidelity of decisions decisions and the innovations. Often, people conflate innovation and  the execution of design. Even if a design is new and a breakthrough, the execution of the design can make or break the how excellent a design truly is. One area to consider for design execution is human centered design. Examples given include the design of a music application. While it might be possible to dpwnload music in a new manner, it does not mean ease of use has been considered. Similary, when considering design decisions for making a new chair, often times, ergonomics and engineering check boxes may be used to create new experiences. However, if human centered design tenants are not considered, the design may still ultimately fail. Ie, s the music app easy to use? Fun to use? Is the chair comfortable? Does it fit in the users environment? For new innovations if human centered designed is a component of the design a better product may emerge, and this is one sign of excellent design. p-prim…

Article: Sometimes more choices leave people worse off

by  • 

Research published in Biology Letters shows that people confronted with too many choices have difficulty making a good decision. The study analyses over 3,700 human dating descisons across 84 speed-dating events. The study found that when the numnber of variable attributes increases (ie heigh, occupation, education background), people made fewer dating proposals. The effect was even stronger as the number of potential partners increased. Another study shows that when participants in a dating study are given more potential partners, their emotional satisfaction is not higher than when presented with fewer options. Other studies have shows that more options cripple a people to not make any decision at all. Consumer studies show that when given limited options, consumers make a purchasing decison, and are happier with the limited set of options. When given large numbers of options, humans and other animals tend to rely on heuristics that help guide decision making. These rules of thumb help to reduce and simplify the decision making proceess by ignoring some information. We tend to default to quick, easy, and recognizable options. We can decide the appeal of a face in 13 milliseconds. So with fewer options, people make quicker decisions. With more options, people…

RE: Tracing the Spark of Creative Problem-Solving

by  • 

Article:  Carey, B. (2010). “Tracing the Spark of Creative Problem-Solving.” nytimes.com. Visited on October 29th, 2012: http://www.nytimes.com/2010/12/07/science/07brain.html Summary:  Puzzles come in a wide variety of formats. They are appealing to people both because of the dopamine rush of arriving at a solution, and also because they shift the brain into an open, playful state. Puzzles are solved in two main ways — either through insight thinking or analytical thinking.  Insight thinking is when an answer comes to a person suddenly, seemingly out of the blue. Analytical thinking involves employing a systematic approach of testing available possibilities. Both types of thinking are typically required to solve challenging problems. The differences between the two approaches have been debated by scientists, but current experiments and brain-imaging studies indicate that they are separate abilities requiring truly different brain states. Test subjects are more likely to solve puzzles using insight thinking when they display brain activity in the anterior cingulate cortex. This activity is associated with the widening of attention, making the brain more open to distraction and to detecting weaker connections. Positive mood appears to shift the brain towards the state required for insight thinking. In experiments where subjects are shown a humorous video…

Haptics and the Uniformity of Gloss

by  • 

For an introduction into the science of haptics, the article, “Primal, Acute and Easily Duped: Our Sense of Touch,” provided great examples about the accuracy and fallibility of our sense of touch. However, the proliferation of touch-sensitive input devices over the past 4 years since it was written didn’t provide the author with any insight into their pending popularity, or the effect they would have on our fingertips. If our fingertips can feel a bump the thickness of one micron, imagine the sensitivity they have even as they slide over a touch-sensitive glass tablet, a glossy plastic mouse, or an anodized smooth track pad. The more our fingertips are required to touch, drag, swipe, and pinch, even over smooth surfaces, the more abrasive those surfaces become over time and the more those subtle abrasions wear on our skin. Glass becomes scratched, plastic becomes scuffed, and biological stains build up on anodized aluminum along with all other surfaces. The point being that these smooth surfaces end up hurting, if not annoying, our fingertips over time. If the fingertips are the equivalent of the fovea of our eyes, why subject ourselves to these increasingly painful disturbances and not return to using an…

RE: Deadline Pressure Distorts Our Sense of Time

by  • 

Article:  Herbert, W. (2011). “Deadline Pressure Distorts Our Sense of Time.” scientificamerican.com. Visited on October 9th, 2012: http://www.scientificamerican.com/article.cfm?id=looming-deadlines Summary:  The perceived difficulty and deadline pressure associated with a task alters our perception of time. In an initial study, subject were presented with a series of tasks of varying difficulty and asked how far away the day of completion felt to them. The tasks that were more complex and work intensive were perceived as being further in the future. To arrive at this result our brains are translating effort into time, assuming that the more difficult tasks must be further away since they will require more work to complete. An opposite effect is encountered when deadlines are associated with the tasks. If subjects are presented with either an easy or difficult task that they must complete by a set date in the future, those with the more complex and effortful task report that the date feels much closer to them than those with the simple task. This effect may sometimes cause us to feel overwhelmed as multiple complex tasks pile up on us, but our skewed perception of time also ensures that we typically complete necessary tasks within the actual amount of time…

Define your terms: What is sex?

by  • 

The article, “Sex Makes You Smarter — Can ‘Virtual Sex’ Do The Same?” was a great example of either knowing your audience too well or over-using jargon. The most prevalent problem in it was the lack of defined terms. The author assumed that the reader knew terms like: neurogenesis, glucocorticoid levels, and dendritic architecture (a case of cognitive blindness). But the biggest failure was the author’s negligence to define the most basic term about which the article was written: sex. What is sex? Who is having it? How are they having it? These questions were unanswered. The research on which the article was based indicated that male rats were the subject of the study and were “exposed” to sexually-receptive female rats. That was it. That was the only definition of sex in the entire article, and it was a very vague definition, especially if one extrapolated it to the realm of human sex, which is known to be complicated and varied. Is the author talking about the sexual gratification of males only? If sex was a form of exercise, as the author explained it was, how much caloric effort should the male engage in to achieve it or what heart rate should…
