Former programmer and web accessibility developer. Past member of the World Wide Web Consortium Web Content Accessibility Guidelines & Mobile Web initiatives.

Background in theatre, one-time dog groomer, runner, Ted talks junkie, and wikipedia fanatic (I am ever curious about just about everything and have an incurable need to know how things work). Certified to command sailing vessels up to 24 meters (day skipper). Not a butcher, baker, nor candlestick maker, however I do like to cook up a storm when the occasion arises. I also cannot resist a good sesh with Cabot Cove's finest, Mrs. Fletcher - particularly the ones featuring "computers" & "The Internet". #theFailedActress

I have met Jakob Nielsen and Don Norman (and sadly I am very proud of that:).

I do like a good riddle. The answers are "wine" and "lettuce".

80/20 rule: A principle for setting priorities on software features: users will use 20% of the features of your product 80% of the time. Focus the majority of your design and development effort (80%) on the most important 20% of the product.

2-second rule: A loose principle that a user should not need to wait more than 2 seconds for certain types of system response. The choice of 2 seconds is somewhat arbitrary, but a reasonable order of magnitude.

3-click rule: The principle that access to any feature of an application, or each logical step in a process, should require no more than 3 clicks - a helpful rule of thumb in trying to minimize the steps necessary to perform tasks. However, religious adherence to this rule, as with many others, is probably misguided.

The magical number 7 ± 2: Miller's Law another rule of thumb which tells that the number of objects an average human can hold in working memory is 7 ± 2.

Fitts’ Law: T = k log2(D/S + 0.5), k ~ 100 msec. T = time to move the hand to a target | D = distance between hand and target | S = size of target | Broadly, Fitts’ Law can be applied by designers to suggest moving target buttons closer and making them larger for extremely commonly used buttons.

Hick’s Law: (1) H = log2
