A team of researchers from Virginia Tech completed the design and prototyping of a new Usability Methods Research Laboratory using participatory design methods. They found that various tools, including virtual reality and low-tech methods, proved helpful in different phases of design.
Daily performance testing is suitable for immediate determination of relevant psychomotor impairment at the start of work. However, managers must remain aware of test limitations associated with job requirements, such as decision-making skills required for driving a truck safely.
A study found that most tractor-trailer truck right-turn warning signs only partially follow human factors guidelines. The researchers created a list of improved sign elements, including a signal word and pictorial representation of consequences. This article aims to design better warnings for safer road interactions.
