Behaviour malfunction

Are we on the right page when we are trying to prevent misuse in the public / consumer environment?

Statistics consistently show that amusement ride injury investigators identify human behaviour as antecedents to failure, including the omission of actions that were required, actions performed which should not have been, and actions that were not performed with sufficient speed and accuracy.

Engineering, the obligation

The Ritual of the Calling of an Engineer is a moving experience. I keep the framed Obligation on my office wall immediately over my shoulder. Initiated by Prof. Haultain and written by Rudyard Kipling (1865-1936), the ritual was first performed in 1925 to remind graduating engineers about critical ethical principles in the practice of their calling of engineering. The cost of engineering failure may be significant harm to others, and there is no room for compromise on good workmanship.

Scary-safe rides

One of the most common questions I receive both in small-talk conversations and media interviews (such as _this one_), is how rides can be scary and safe at the same time. A student asserted to me just the other day that rides were “notoriously dangerous”. This is actually quite inaccurate.

Accessible theme parks

I just finished reading “Theme Park Design: Behind the scenes with an engineer” by Steve Alcorn. I picked it up at the Bookstore during the IAAPA Expo in Orlando last month and took advantage of the flight home to read quite a lot of the way through. The book describes in a very realistic way how talented people make plans–and adapt to reality–using examples from his own career in show engineering with a number of theme parks, as employee and as contracted consultant, including many examples from his role in the organization now known as Walt Disney Imagineering and particularly the construction and launch of Disney’s second Florida park: Epcot. The book clearly differentiates the many specializations required to conceive, design, plan, build, test, and operate an amusement attraction.

In the queue

Any service involves queueing, whether it is a doctor’s office or public transit. The queue is the area where you wait for service. Sometimes you are literally in a line and other times you are more of a herd, and sometimes you’re lucky enough to arrive at the point of service to find no one waiting (instabus!) but queueing is a fact of life. Waiting to ride an amusement ride typically involves a queue, and this becomes sort of the folklore or fiction of the activity.

Teaching

As Labour Day approaches, thoughts turn to teaching. There are those who think research is what academics really prefer to do, that research entails hiding in the lab or library far from real problems, and that we teach only under duress. However, that has certainly not been my experience with either teaching or research.

Trouble signs

For the past five years or so, we have been compiling, reviewing and extending the relatively scant scientific evidence about musculoskeletal injuries and sign language interpreting (SLI).

Decision making: words and meaning

Decision-making succeeds when the decision produces a desirable outcome and fails when it produces an undesirable outcome. Decision-making can fail when a person does not perceive, ignores, cannot understand, or gives improper weight to a piece of relevant information.

Where is the lab?

Human factors research is focused on solving authentic end-user problems. The first key to solving a problem is to define it and authentically understand the problem. The only way to do that is through engagement with end users and the problem domain. If I want to solve a problem related to amusement rides, then I have to spend time on the midway. I have to spend time not just looking at them but listening to them. If I focus on “efficiency” of the use of my time, I risk seeing them as the variables and comparing them to the norms I bring with me. If I want to solve their problems, I need to muster the generosity to spend enough time to understand what features of the midway are actually constants.

Where did I come from and where am I now?

Through this blog, I will comment on human factors engineering and ergonomics (HF/E), so a fair starting point is what does HF/E mean to me?
