One of my students last semester (thanks, Ronney!) turned me on the “Callback” publication from the NASA Aviation Safety Reporting System. These are almost all first person stories written as case studies of errors and accidents or near accidents. There aren’t so many that it falls under my list of neat databases, but it certainly is interesting reading. I’ve collected [...]

What values are pilots allowed to enter for the weight of the plane?

January 22, 2012
Thumbnail image for What values are pilots allowed to enter for the weight of the plane?

I’d assume when pilots enter a weight estimate for the plane prior to takeoff that there would be a decision aid to prevents gross miscalculation. It certainly seems like an undue load (no pun intended) on the pilot to require entering multiple components for weight correctly. From the article linked below I am no longer sure how much automation is [...]

Neat SciAm Blog Post on InfoVis

This story was passed to me today by Matt Shipman, who writes about research on The Abstract. An excerpt: [Right - Comparison of two road signs, Highway Gothic on the left, Clearview on the right, 2007.

Intuitive Interfaces for Software Developers

January 9, 2012
Thumbnail image for Intuitive Interfaces for Software Developers

Here is a link to some neat new research being done by my colleagues at NCSU.  It’s about the development of a tool that instantly changes the look of software code as it’s being developed, allowing for different ways to investigate bugs and features, but without changing the code in any way that might introduce errors. Dr. Emerson Murphy-Hill developed the interface [...]

Influence of Environment on Behavior

January 4, 2012

Two articles came up that both touched upon the topic of how behavior is shaped and influenced by the environment and how we shape our immediate environment to suit particular behaviors.  The topic of how behavior is constrained by the physical environment is a long discussed topic in psychology and human factors (e.g., affordances, ecological psychology, situated cognition, “cognition in [...]

ATM Accessibility (not)

January 3, 2012

I’m catching up on some older topics I never blogged about. This is one of my favorites. The Consumerist posted a video of a blind user interacting with an ATM. As they said, “Overall, it seems like whoever designed the ATM didn’t ask a blind person to try it out first.” Quotes from the video: (Re: finding the headphone jack) [...]

December 27, 2011

Enjoy this video by Tristan Cooke and Thomas Nelson at Humans in Design. Some of the blame for our current financial crisis lies in the opacity of legal documents. In this post, a mortgage statement gets a facelift to become easily interpretable and allow the homeowner to predict and well as understand the payment schedule.   The Mortgage Statement Fix from [...]

Paper isn’t so bad…

December 15, 2011

One thing that annoys me is the silly argument that paper is bad or paper kills. Such hollow arguments are used to encourage technology adoption in airplane cockpits, the class room, and hospitals. Usually they are associated with silly statistics about how much paper is saved or how much less weight is carried, or how much easier it will be [...]

Virtual Assistants (automation) and Etiquette

December 6, 2011

This NYT article discusses the “new” scourge of rude people interacting with their phones in public via voice thanks in large part to Siri, Apple’s new virtual assistant. This article reminded me of something slightly different about human interaction with virtual assistants or automation. In a 2004 paper, researchers Parasuraman and Miller wondered if automation that possessed human-like qualities would [...]

Little Printer Concept

November 29, 2011

In the “why didn’t I think of this!” department, we have the Little Printer Concept by Berg.  It basically seems like a cash register thermal printer (in much nicer packaging) that sits in your home and prints messages, puzzles, etc.   I could see this being very useful for older consumers who are resistant to technology.  Imagine printing medication instructions [...]

Follow the link to read “A Brief Rant on the Future of Interaction Design” by Bret Victor. The briefest of summaries would be that we over-use simple touch in our visions of the future, when we could be including many other cues, such as weight and balance. From the post: If you’re with me so far, maybe I can nudge [...]

Speedometer Design

November 2, 2011

This page contains an interesting inventory of past speedometer designs from Chevrolet.  Quite a variety!  Is usability getting better or worse? I like it when the design works such that the prevailing speed limit (e.g., 60 MPH) lets the needle be oriented in a cardinal direction (pointed up or left) like the one below: (via Kottke) Similar Posts (auto-generated): HF [...]

Any aviation experts want to chime in about a knob turning a plane upside down? Also, please note this was characterized as “pilot error.” Pilot error causes airliner to flip, fly upside down From the article: According to the safety board, an analysis of the aircraft’s digital flight recorder indicated the co-pilot, alone in the cockpit while the captain used [...]
