Evil Interfaces

May 3, 2010

Excellent post at the EFF describing “evil interfaces“, or interfaces that may be deliberately designed to make you do things you did not intend to do: As Conti describes it, a good interface is meant to help users achieve their goals as easily as possible. But an “evil” interface is meant to trick users into doing things they don’t want [...]

Facetted Navigation Primer

April 22, 2010

A List Apart recently posted an excerpt from Chapter 4 of Search Patterns by Peter Morville and Jeffery Callender that presents a great description of facetted navigation (FN), a type of search interface. FN is contrasted with just text searching (e.g., Google), taxonomies (e.g., Windows Explorer or Mac Finder), and tag-based interfaces (e.g., Flickr).  See illustrative figure below if you [...]

Personas & Windows Phone 7; Apple Mouse Fix

Two unrelated posts; both usability-related: I’m sure that Microsoft has used personas in design and evaluation before, but have they advertised it so broadly–even bragged about it?  I think one of the major benefits of personas is that it focuses development (and evaluation) reducing feature creep; something that the old Windows phones were definitely guilty of [Engadget]. This third-party “fix” [...]

Slate.com has a nice article on the difference between U.S. exit signs and the rest of the world, as well as a nice history of the evolution of the symbols.  Here is an excerpt to get you interested: The text-based American exit sign has its origins in the 1911 Triangle Shirtwaist Fire, a blaze in a downtown Manhattan garment factory [...]

The Consumerist blog (of Consumer Reports) posted an article on the state of California suing Sony because their online Playstation services were not accessibly designed. Quoted from The Consumerist post: At the crux of the plaintiff’s failed case was their contention that, because PlayStation allows people all over the world to connect and play games together via their now-repaired PlayStation [...]

Tabs, tabs, and more tabs…

This post on Smashing Magazine about vertical navigation had me thinking about the book Anne and I are writing (manuscript due this Friday; panicking…I’m a 10 on the Wong-Baker scale).  In one of the chapters I discuss tab navigation.  When I was looking for a particularly bad example of the use of tabs I remembered Amazon’s website circa 2000.  Fortunately, [...]

I don’t visit the doctor frequently (less than once a year) but last year I went to the doctor and as part of the paperwork, I encountered a question about how much pain I felt (shown above). This is the Wong-Baker FACES Pain Rating Scale (which seems to be available online).  I thought this was a great way to ask [...]

Today’s potpourri happens to be related to understanding or enhancing what your users see (or don’t see): Google Browser Size let’s you see how much of your web content is visible by users. Rocker Lou Reed (of the Velvet Underground) designs an iPhone app for near-sighted users.  It basically increases the font size in the contacts application.  It appears that [...]

I‘ve recently published two papers on the topic of human factors and healthcare. Each paper covers a different “stakeholder”: the older patient and the nurse.  The first paper is available for free but the second paper (a collaboration with my architect colleague Dina Battisto) is available at your local library (or you can request a PDF reprint from me). Pak, [...]

One of my major interests at the moment is in the use of technological tools (primarily the Web) in the management of health.  So it was with great pleasure that there was so much research on this topic (I will mention more in future posts). The first was presented in the Aging session (where Anne was program chair).  Jessie Chin [...]

Showing off her BrailleNote, she said she prefers reading Braille, as opposed to listening to [...]

Augmented Reality for Everyone

July 16, 2009

There have been many recent examples of consumer friendly augmented reality applications for smart phone users.  I remember reading about augmented reality research over a decade ago (in an HCI class) and remembering how bulky, expensive, experimental, and out-of-reach it seemed back then.  The systems back then required head-mounted displays and were physically attached to cameras and large computers.  Now [...]
