Perceptual Illusions

by  • 

Our minds play tricks on us all the time. Once the information has entered our cognition via our senses, it still has to get processed to be understood. Like any other data, it’s all about context. For interesting examples of optical illusions, please visit http://www.lottolab.org/articles/illusionsoflight.asp. R. Beau Lotto has put together a few interesting examples of mis-processing! Or watch him deliver a talk at TED.

On “For digital artists, apps provide new palette”

by  • 

Harmanci, R. (2010). “For digital artists, apps provide new palette.”  New York Times Online. Retrieved on October 4, 2010: http://www.nytimes.com/2010/08/20/us/20bciart.html To illustrate the impact of mobile/handheld-device technology on the arts, this article describes the work of several individual artists who have used iPhone/iPad applications as an artistic format. In my overview, I focus on the work by Scott Snibbe and pose the following question: what is it about handheld apps that sets them apart and makes them a more successful environment for interactive art than any other? Scott Snibbe is an artist for whom interactivity, i.e. the opportunity for audience participation, is a central theme. His installations are often designed to capture human bodily actions and respond to them. The audience thus has the experience of bringing an art piece’s content into existence. For example, in Falling Girl (2008) and Make Like a Tree (2006), people’s movements are replicated, with some time lag, by silhouettes projected onto screens, while in Blow-Up (2005) people’s breath triggers fans that reproduce its spatio-temporal contour.  Snibbe’s very popular mobile apps are closely based on an earlier Dynamic Systems interactive series that involved manual action, except that their original version used more traditional cursor-based interface. …

On “3-D Printing Spurs a Manufacturing Revolution” by Vance

by  • 

Vance, A., (2010). “3-D Printing Spurs a Manufacturing Revolution.“ New York Times Online. Retrieved on October 6, 2010: http://www.nytimes.com/2010/09/14/technology/14print.html Summary: Vance highlights the remarkable impact and wide application 3-D printing has on a wide range of traditional and non-traditional manufacturing industries. While traditional printers print on one dimensional paper, 3-D printers create a 3-dimensional physical object, usually from plastic or metal, by stacking layers one on top of another. The application of 3-D printers spans a wide variety of applications: from custom made prosthetic casings to building houses, and literally anything in-between. It may very well hold the promise of a game-changing technology for the US manufacturing industry in that the cheap labor may no longer be the “be-all” important factor it is today. User Groups While the application of technology in design and manufacturing hardly is a new phenomenon, the scale, ease of use and its wide application do provide something of a paradigm shift in a cross-section of manufacturing industries. In tomorrow’s 3-D printing world, yesteryears chasm between conceptual design and manufacturing is a non-existing obstacle. In this new 3-D printing world the virtual product concept conceived by the product creator and the material manifestation of her/his creation…

Antisocial Networking?

by  • 

Stout, H. (2010). “Antisocial Networking?” New York Times Online. Retrieved on 3 October, 2010: http://www.nytimes.com/2010/05/02/fashion/02BEST.html The main topic of this article is that technology may be changing the very nature of kid’s friendships. Children used to actually talk to their friends. But now, even chatting on cellphones or via e-mail is becoming rare. Today’s teenagers and preteens, prefer to make friends and communicate using cellphone texts and instant messages, or through the very public forum of Facebook walls and MySpace bulletins. People now are more likely to use their cellphones to text friends than to call them. The article shows two opposite points of view on the topic. The author believes the quality of human interactions is becoming worse without the intimacy and emotional component of regular face-to-face communications (hence the title of this article). The ease of electronic communication may be making teens less interested in face-to-face communication with their friends, but close childhood friendships help kids build trust in people outside their families, develop empathy, understand emotional nuances and read social cues like facial expressions and body language, and consequently help lay the groundwork for healthy adult relationships. On the other hand, online social networking allows children to become…

Using Menu Psychology to Entice Diners

by  • 

Kershaw, S., (2009). “Using Menu Psychology to Entice Diners.” New York Times Online. Visited on October 02, 2010: http://www.nytimes.com/2009/12/23/dining/23menus.html. This article discusses how an understanding of human psychology is being applied to sculpt a restaurant menu into a lucrative tool for the restaurateur. Restaurateurs play down the importance of the cost figure by eliminating the dollar sign and decimals. Adding a personal touch to an item (‘Grandma Mary’s cake’) or a descriptive menu label (‘buttery pasta’) draws more attention to the dish. Other decoys include using a description that glorifies a more profitable dish compared to others. During the tough economic times in the last year, some restaurants were reinventing their restaurants through such menu design techniques, and were hoping that would make the difference they needed. Conceptual design: When you go to a restaurant, good food is not the only thing you seek; you are looking for a good experience. Of course sometimes, great food can make us turn a blind eye to any other inadequacy and draw us back into the restaurant. Nevertheless, a good experience overall manifests itself as a stronger loyalty. If your overall experience has made a lasting positive impression, you may recommend the restaurant…

What is a p-prim?

by  • 

Beliefs on the relative size of Earth versus the Sun.

I’ve been using the p-prim ever since I’ve learned of them, back in my graduate school days at UC Berkeley. P-prims stand for phenomenological primitives and were “invented” by Andrea diSeesa, a UC Berkeley professor in the School of Education who also happens to be a physicist (diSessa, 1983). Visit his Wikipedia page and check out some of the cool projects he’s working at now. Before I give a definition of a p-prim, I think it would be good to give a few examples. Here’s a graph published by OkTrends on beliefs of various groups (in this case as defined by their sexual orientation) about the relative size of our sun versus the Earth (our planet). Even disregarding the differences in percentages due to sexual preference, an awesome 5 % to 10 % of our population believes that the planet we live on is larger than the star it orbits. Would this qualify as a p-prim? Yes: it’s not a formally learned concept; it describes a phenomenon; it’s a bit of knowledge based on personal observations: the sun looks like a small round disk in the sky; it’s a useful problem-solving tool when one has to draw a picture with…
