Challenges in the Usability Evaluation of Agricultural Mobile Machinery
Published in Philip D. Bust, Contemporary Ergonomics 2006, 2020
Agricultural engineering is a new field in human centred design so there are no established usability techniques and measures. Examples in other domains have shown that an easy-to-use interface is critical for successful adoption and use of application. An important research issue therefore is how to conduct an appropriate usability test. Usability testing is an evaluation method used to measure how well a specific user can use a specific product or a system in a specific situation, aiming at to achieve the best possible interaction and relation between the user, the product and the task.

It is also important to work to ensure that device components are of reasonable size and manipulability and to consider potential impairments such as tremor, as about 10% of adults over age 85 – one of the fastest growing age groups in the U.S. – exhibit essential tremor. Usability testing with a representative user sample will generate useful feedback about how well and efficiently the design works. Keep in mind that healthcare devices and systems are used by diverse populations and include not only the patient but also caregivers and healthcare professionals.

In order to measure the level of user satisfaction, as well as effectiveness and efficiency of the product, usability testing is a required process. Usability evaluation allows designers to see what users actually do when they use the product, what works best for them and their preferences. Usability testing refers to activity that focuses on observing users using a product, performing tasks that are real and meaningful to them (Barnum, 2011).
Usability tests of ideation flexibility tools with engineering design practitioners

The aims of this usability study were satisfied both from the perspective of answering our original research questions and in introducing new directions for investigation that will lead to a better understanding of ideation tools, their outcomes and the performance and perceptions of those applying them. Usability testing is a critical step in the design process in which input from prospective users is used to investigate new products and provide feedback on how that product might be improved. These goals are just as applicable to design tools as they are to the products that result from those tools, making it important to leverage usability studies in our development of the three ideation flexibility tools—the Problem Framing Profile, the Design Heuristics and Cognitive Style-Based Teaming.

Usability testing is designed to evaluate a service or product in terms of effectiveness, efficiency, and satisfaction. The principal dissimilarity between other tests and usability tests in the software development process is the fact that real users of the system are involved in the test. Users cannot be substituted by members of software development team as there could be some biases by providing unreliable test results (Drygielski et al. 2019).
Overcoming COVID-19 pandemic: emerging challenges of human factors and the role of cognitive ergonomics
Published in Theoretical Issues in Ergonomics Science, 2023
The purpose of usability testing is to evaluate user interfaces and ensure system quality. Systems with better usability lead to higher human performance and satisfaction with interaction with them (Lin, Choong, and Salvendy 1997).
