I realize that we are finished with our instructions assignment but still thought this article was interesting and relevant to this course.
This article examined the usability of instructions for assembling toys for young children. The study was performed with 24 participants ages 6 and 9 of mixed gender and analyzed speed and accuracy of assembly as well as time spent looking at the instructions. The children had difficulty with all but the simplest form of instructions and the older age group had more success with assembly, which makes sense. Girls in the 6 year old group had the most difficulty with assembly and girls in the 9 year old group reported having the least amount of fun. It was determined that product age recommendations often do not accurately reflect usability and many picture instructions are poorly formatted or displayed.
This article really shows the importance of writing (or drawing) for your audience and the effect the instructions can have on the satisfaction of the intended users.

Texting While Driving
This week I read an article on the effects of texting while driving, and since Clemson has recently outlawed texting while driving I figured this would be pretty applicable to us as students.
The objective of the study was to determine the impact of text messaging on simulated driving performance. 40 participants engaged in both driving-only and driving-while-texting scenarios in a driving simulator. Results showed that texting drivers responded more slowly to brake lights and showed impairments in forward and side-ways control of the vehicle. Text messaging drivers were also involved in more crashes than drivers that were not texting. The article concludes that texting while driving has a negative effect on driving; even more so than talking on a cell phone while driving.
I think we can all agree that text messaging while driving is more dangerous than paying full attention to the road. Even though it has been outlawed in the area, how many people still sneak a quick text in their car every once in a while?

Motorcycle Conspicuity
This week I read an article in an Industrial Engineering related journal called Human Factors.
The article investigated the use of daytime running lights on motorcycles and its effect on visibility, or in other words, how "conspicuous" the motorcycle is. I ride a motorcycle so I found this article very interesting.
The article argues that motorcycles are inconspicuous; therefore the ability of other drivers to detect them and respond effectively is reduced. A study was conducted with 75 volunteers that watched video clips of different roadways and scenarios. The participants were asked to indicate when they saw a potentially hazardous situation such as pedestrians, motorcycles, or traffic cones. Their reaction times were collected and analyzed. The results show that there is significant correlation between motorcycles with daytime running lights and the driver of the other vehicle's ability to respond to them effectively. The study also shows that driver's ability to react properly decreases with age (that one's probably obvious).
The lights on my motorcycle are on if it's running, so hopefully I am more visible. Has anyone ever had any close calls with a motorcycle or moped while driving due to them being hard to see?
