 Wearable technology has become increasingly popular in recent years, with applications ranging from fitness tracking to prosthetics. However, there is currently no standardized methodology for evaluating the usability of such systems. To address this issue, we propose a five-step approach for developing a protocol for measuring the usability of wearable systems. First, the target users must be defined, along with the tasks they will perform while using the system. Next, a task analysis is conducted to identify the parameters to be measured and the methodology used to collect data. Then, a protocol is created which includes the preparation of questionnaires or other measurement tools. Finally, the experiment is executed and the collected data analyzed and reported. By following this protocol, researchers, developers, and users can better understand how to improve the deployment of wearable systems and increase the quality of life.
