Knowledge, Context, and Expectation Part II

I first came across this image years ago in our pediatrician’s office. It made everyone who saw it laugh. The young boy—less than a year old, probably—has very limited world experience. But somethings he knows well—food comes out of those! The boy recognized the imagery, but with his limited background knowledge of art and contextual experience, his expectations of milk were quickly dashed (to the complete amusement of his mother). While we enjoy the boy’s predicament, it is good to keep in mind that the products we create can put our users at a disadvantage. The product’s audience can similarly have limited background knowledge, misinterpret the context, and be left with unexpected consequences. And a loving mother might not be there to console them…

Cultural Difference: Kids Stories

I came across this short video: “The White Wolf” by Pierre-Luc Granjon. It is an 8 minute animation short about two brothers living in a small French village. Please pay attention to the story-line (I know it is an obvious thing to pay attention to): would it have been received well in US? Note that it is not more gruesome than “Snow White”… This is why cultural context is so important to product design and why I teach the class!

Knowledge, Context, & Expectation

These are three necessary components of any product design: Knowledge: the background information that forms the foundation of product design Context: the ecosystem in which the product will be used Expectation: the alignment of goals between product creators and the users for which it was designed A failure to fully understand any of the above variables results in errors that propagate throughout the product system. But what if the product is disaster preparedness? Consider the design of an evacuation plan ahead of a disaster. You would need to understand the what kinds of damage the disaster is capable of wrecking; the probabilities for each outcome; the people and the ecosystem in which the disaster will occur; and expectations of all the participants in the evacuation plans. Tsunami and The Zoo A few years ago, I was teaching a fifth grade science class where we were discussing the possible damage from a tsunami in San Francisco (we just visited the Bay Model). The problem I posed to the students was to design a reasonable evacuation plan for The San Francisco Zoo animals. The Zoo lies on the tsunami flood plane, and as far as we knew there was no plan for…

Trolls, Dolls, and Poupees

The first time I saw her, she was riding on a bus. Her hair was long and golden. Her eyes were amazing blue. She was stylishly dressed in a mini skirt and had a cool pair of earrings. But what got me—what burned that moment into my memory forever—was that her long slender legs bent without any visible joints. She was amazing. I wouldn’t see another like her until many years later, when my family was emigrating from Russia and living Vienna. Not far from the apartment we stayed in, there was a toy store and it was filled with wonders just like the one I remembered from so many buses ago: Barbie. When I was growing up in Russia, I played with dolls and poupees—all girls did. The dolls were made to resemble little kids, with big eyes, big heads, chubby cheeks, and cute clothes. I used old buttons and odd bits of cloth and lace to make them new clothes and bedding. My play mainly consisted of creating cool things for my dolls—I liked to sew and glue. And I don’t think that my play was all that much different from girls’ 100 years before—my dolls would have…

Topical Iodine in Case of Radioactive Iodine Release

It’s been difficult to get hold of potassium iodide tablets—people on the West Coast are getting worried about the possible farther radiation leaks from Japanese nuclear reactors and are trying to stock up. Fortunately, the topical iodine can work almost as well in an emergency. Betadine is a topical disinfectant and is usually easy to get. Here’s a reference to the study that shows the effectiveness for this purpose of Betadine absorbed through the skin of the abdomen: Toxnet.mln.nih.gov A 2 percent tincture of iodine on the abdomen over an area of approximately 200 mm by 100 mm works for adults as a preventive measure in a case of radioactive iodine presence in the atmosphere. When I was growing up, we were taught to draw a tic-tac-toe grid on our chests or a happy face on a tommy—it’s about the right amount and it is less scary for kids. Iodine will stain the skin and it will take a few weeks for the coloration to return to normal—be careful where you draw the happy face! A short note on use: Under no circumstances should Betadine be injested. It is poison. It is only for external use. Don’t use Betadine until…

Information Awareness & Failure Analysis

Given the current state of affairs in Japan’s nuclear facilities, I thought it would be good to do a quick analysis of what’s going wrong and why the officials on the ground act as they do (based on very limited information that’s trickling in via the news sources). As of today (morning of March 14th), we have two reactors that have experienced explosions, partial core meltdowns, and multiple other failures. I’ve put together data from the news with failure analysis for an alternative view of the ongoing nuclear crisis in Japan. Like many aspects of usability, FAA (Federal Aviation Administration) was the first to develop practical understanding of Information Awareness and Failure Analysis—pilots and airplane designers what to minimize errors in flight and understand failure when it happens. Like the rest of the world, I’m extremely grateful for their insight into these two aspects of systems design and usability. Below is a quick introduction to the basics. Information Awareness Information Awareness is a wonderful term that describes the state of user’s knowledge of the problem at any particular time. This means that Information Awareness changes in time and from person to person. For designers of a complex system that aims…
