Abstract A key objective of the MEDSReM-2 study is to promote medication taking decisions and improve adherence to hypertensive medications for older adults. New functionalities include enhanced decision-support algorithms for missed medications, automated entry of blood pressure measurements, improved data visualizations, and an easy-to-use online web portal. In support of these enhancements, the User Testing subteam is tasked with providing ongoing evaluation and feedback on the usability of early design concepts, prototypes, beta software, wireless blood pressure monitors, and instructional materials. The overall project comprises multiple working teams, whose efforts must be coordinated. We will describe the challenges of working with these interdisciplinary teams and the usability evaluation methods used to support the needs of each team in creating the enhanced MEDSReM-2 system that is easy-to-use and effective in helping older adults improve their hypertension medication adherence. These processes inform the research and design efforts of other technology interventions.

Usability Evaluation Methods

Usability is a fundamental quality characteristic for the success of an interactive system. It is a concept that includes a set of metrics and methods in order to obtain easy-to-learn and easy-to-use systems. Usability Evaluation Methods, UEM, are quite diverse; their application depends on variables such as costs, time availability, and human resources. A large number of UEM can be employed to assess interactive software systems, but questions arise when deciding which method and/or combination of methods gives more (relevant) information. We proposeCollaborative Usability Evaluation Methods, CUEM, following the principles defined by the Collaboration Engineering. This paper analyzes a set of CUEM conducted on different interactive software systems. It proposes combinations of CUEM that provide more complete and comprehensive information about the usability of interactive software systems than those evaluation methods conducted independently.

Although advancements in home-use technologies have allowed users to take control over how they monitor their health, their likely inexperience with such technologies can lead to use errors. The study aimed to determine the usability of a home-use blood pressure monitor, which included the device and instructional materials. Nineteen participants completed a 45-minute study which included an out-of-the-box handling scenario without moderator facilitation. The primary goal of this scenario was to determine if participants would be able to classify their heart rate reading obtained from the heart rate monitor as either low, average, or high in accordance to the thresholds set by the device. Although a majority of users were able to complete the use scenario, users nonetheless experienced major use errors and had difficulty with correctly placing the blood pressure cuff on their arm or inadvertently inflated the cuff when simply trying to turn on the device. There were also differences in the instructional materials such as how users should place the cuff around their arm. These inconsistencies were exacerbated by ambiguous wording without any pictorial clarifications. Additionally, 10% of users were unable to locate information on how to interpret their blood pressure readings. These findings highlight the importance of studying the usability of at-home blood pressure monitors to ensure more accurate health monitoring of users.
