Assisted Living Systems: Human Factors Considerations

Although many older adults wish to live independently, remaining in their own homes as long as possible, they may face obstacles such as transportation issues, social isolation, upkeep of the home, and increasing in-home care costs, which prevent them from doing so. The use of technology within the home, through technology-based assisted living systems, has the potential to alleviate some of these obstacles. Incorporating human factors principles to maximize safety, efficiency, and usability is key to the development of these systems

How Well Do Drivers Understand Their Own Headlights?

The current research represents an initial investigation of drivers’ understanding of high beam and low beam headlight patterns in a nighttime driving environment. Fifty-four university students used a highlighter to indicate on a paper diagram of a roadway scene the portion of the scene that they felt their headlights would illuminate. Although the headlight patterns produced by participants varied more than expected, several consistent patterns emerged. Classification and evaluation of these drivers’ responses revealed that many drivers misunderstand the area of the roadway that is illuminated by their headlights. These misunderstandings fall into fairly distinct patterns. The results indicate many drivers possess an incomplete understanding of the pattern of illumination provided by their headlights. These results are consistent with earlier evidence that many road users fail to appreciate the visibility challenges that exist at night

Parents’ Views of a Classroom and Closed-Road Post-License Driving Program for Teen Drivers, Guard Your Life

In the US, teenage drivers have an increased risk of being involved in crashes. To address this, post-license advanced driving programs have emerged. This study gains parents’ perspectives while observing their teens’ involvement in a post-license driving program focused on a hands-on introduction to emergency braking, skid recovery and the dangers of distracted driving. Parents completed a survey after the program, and for comparison purposes, the teens also completed a survey at the end of the program. While the parents only observed the program, the results revealed that most learned useful information and would consider additional training for themselves. Almost all teens and parents reported anticipating changing their driving behaviors, specifically by reducing distractions, having a heightened awareness and changing their driving position. These results suggest that parents benefited from simply observing the class

A User-Centered Design Exploration of Factors That Influence the Rideshare Experience

The rise of real-time information communication through smartphones and wireless networks enabled the growth of ridesharing services. While personal rideshare services (individuals riding alone or with acquaintances) initially dominated the market, the popularity of pooled ridesharing (individuals sharing rides with people they do not know) has grown globally. However, pooled ridesharing remains less common in the U.S., where personal vehicle usage is still the norm. Vehicle design and rideshare services may need to be tailored to user preferences to increase pooled rideshare adoption. Based on a large, national U.S. survey (N = 5385), the results of exploratory and confirmatory factor analyses suggested that four key factors influence riders’ willingness to consider pooled ridesharing: comfort/ease of use, convenience, vehicle technology/accessibility, and passenger safety. A binomial logistic regression was conducted to determine how the four factors influence one’s willingness to consider pooled ridesharing. The two factors that positively influence riders’ willingness to consider pooled ridesharing are vehicle technology/accessibility (B = 1.10) and convenience (B = 0.94), while lack of passenger safety (B = −0.63) and comfort/ease of use (B = −0.17) are pooled ridesharing deterrents. Understanding user-centered design and service factors are critical to increase the use of pooled ridesharing services in the future
