Mechanical Engineer Michael Salame describes the property of oleophobia and its value in medical devices. 

This new technology seems pretty interesting…the implications are kind of mind-blowing.

Tapping your forearm or hand with a finger could soon be the way you interact with gadgets. The Skinput system makes it easy to control gadgets by tapping on the arm.

US researchers have found a way to work out where the tap touches and use that to control phones and music players. Coupled with a tiny projector the system can use the skin as a surface on which to display menu choices, a number pad or a screen.

Context is everything when doing front-end, qualitative research for product development. It’s one thing to ask open-ended, probing questions about the task under consideration, but it’s another to ask those questions in a setting that allows an interviewee to interact with his or her environment as he or she answers. In someone’s “natural” environment, you will get much deeper recall, demonstration and insight than you typically will in a focus group facility. But, when you are interested in doing this type of work with health care clinicians, being able to do a deep extended interview in a clinical environment can be the stuff of dreams – due to the hectic and sometimes chaotic nature of clinical healthcare settings. Imagine trying to interview an emergency room nurse about a particular device that she regularly uses – in the middle of the emergency room.
