Principles of Effective Experience

4

1. Concerned with, or having the function of, carrying into effect, executing, or accomplishing; (of a cause) that makes something to be what it is, efficient (cf. effective cause n. at Special uses). / Having the power of acting upon the thing designated. (OED). 2. That produces its intended effect, or adequately answers its purpose (OED). 3. The removal of all technical barriers to effective interaction -- this is my definition.

Effective1, effectual2, accessible3. To my way of thinking these three terms mean the same thing, and in reality were going to be talking about accessibility. However, you should be thinking of accessibility in more general terms; the more general terms of effective or effectual use. This is because the concept of accessibility is much broader than the narrow confines of disability it is often associated with [9241-129:2010, 2010] .

Access is for Everyone...

"While pedalling a Boris Bike I start to shuffle in my pocket. Where is that damn iPhone. Finally, I find it. The next challenge is to get it out my pocket whilst still navigating the Humvee of the bike world. Eventually, I give up. I pull over and get my iPhone out. I look up the nearest docking station with spaces and get back on my way."
