Expressing emotions through vibration for perception and control

ur Réhman, S.  2010.  Expressing emotions through vibration for perception and control. Faculty of Science and Technology, Department of Applied Physics and Electronics. Doctor of Philosophy (PhD):159.

Umea University's Shafiq ur Rehman has developed a system that offers visually impaired users a method for interpreting people's facial expressions. The system features a Web camera, hardware the size of a coin, and a tactile display. The system converts visual information from the camera into advanced vibrating patterns displayed on the skin. "The vibrators are sequentially activated to provide dynamic information about what kind of emotion a person is expressing and the intensity of the emotion," Rehman says.

Association of Interruptions With an Increased Risk and Severity of Medication Administration Errors

[Anonymous].  2010.  Association of Interruptions With an Increased Risk and Severity of Medication Administration Errors. Archives of Internal Medicine. 170:683-690.

Background  Interruptions have been implicated as a cause of clinical errors, yet, to our knowledge, no empirical studies of this relationship exist. We tested the hypothesis that interruptions during medication administration increase errors.

Governing Lethal Behavior: Embedding Ethics in a Hybrid Deliberative/Reactive Robot Architecture

Arkin, RC.  2009.  Governing Lethal Behavior: Embedding Ethics in a Hybrid Deliberative/Reactive Robot Architecture.

Georgia Institute of Technology robotics engineer Ronald Arkin has dedicated his life's work to the development of ethical battlefield robots embedded with a sense of guilt that could eventually make them more effective than human soldiers at reducing civilian casualties. Arkin says the robots would be designed to comply with internationally prescribed laws of war and rules of engagement.

MacBook Wheel - When good designs go bad

The Onion New Network did a brilliant parody: The MacBook Wheel. It takes the simple iPod interface and places it into a complex device, i.e. a laptop. The results are hardly satisfactory. But it's a great way of demonstrating how a good inteface in one domain becomes poor in another. Check out the video
