Notes about interface

January 24, 2011 permalink


I need to bring this theory up the next time I’m asked to create another link farm or overly-featured application. Neil Hunt, Chief Product Officer of Netflix, responds to a question on Quora about A/B testing and usability (in the comments):

“Simple trumps complete” – a 5% feature (used by less than 5% of all users) is a distraction for all the other users, and is better removed, unless its really critical (a small number of users do need to cancel service, for example).

I have this mental model of particles of attention that a user brings, a finite quantity that they will spread around according to what catches their attention. I call them “attentrons”. An extra tab or button will attract a bunch of attentrons that are not then available to focus on other areas. So the tab had better be *better* than the competing areas of the site to avoid diluting the results, or it’s better off removed.

Mind-Controlled Addams Family Pinball

Mind-controlled Addams Family pinball! But can you do it with a lit lightbulb in your mouth?

Compared to invasive Brain-Computer Interfaces (BCI), non-invasive BCI systems based on Electroencephalogram (EEG) signals have not been applied successfully for complex control tasks. In the present study, however, we demonstrate this is possible and report on the interaction of a human subject with a complex real device: a pinball machine.
