Augmented Reality Eyewear for Assisting in the Preparation and Control of Cancer Therapies: Assessing the Learning Curve and Level of Adoption.

Since March 2022, the centralized cytotoxic preparation unit at the Lille University Hospital (Lille, France) is equipped with augmented reality eyewear for preparation and quality control. The technology enables a user-friendly guided step by step preparation process. It also assists the user by identifying vials through data matrix scan and recording photos at different stages of preparation in order to replace the in-process double visual inspection which will now be carried out a posteriori during the release control.

Usability Evaluation Ecological Validity: Is More Always Better?

Background: The ecological validity associated with usability testing of health information technologies (HITs) can affect test results and the predictability of real-world performance. It is, therefore, necessary to identify conditions with the greatest effect on validity.

Method: We conducted a comparative analysis of two usability testing conditions.

Evaluations of medical device usability during clinical investigations: a scoping review of clinical study protocols.

Objective: Combining clinical investigations with usability studies provides valuable information for medical devices evaluation. But both types of study are very different in terms of objectives and methodologies. How are usability studies integrated into clinical investigations in practice?

Methods: We searched the ClinicalTrials.

Detectability of use errors in summative usability tests of medical devices: Impact of the test environment.

The regulations on summative usability evaluations of medical devices (MDs) emphasize that the test environment must have sufficient ecological validity for generalization to real-life use. Here, we examined the influence of environmental fidelity (a component of ecological validity) on the detectability of MD use errors. A total of 140 participants participated in a summative usability evaluation of an anaphylactic shock auto-injector device under either a high-fidelity condition or a condition acceptable from the manufacturer's perspective, lower-fidelity condition.

Teaching Module to Train Students in the Participatory Design of Digital Technologies for Disability Assistance.

Teaching the principles of participatory design to students mainly interested in digital skills is important because user-centered approaches have become essential in the field of new technologies when we want to guarantee that a product will meet the needs of its end-users. Working with technologies dedicated to the disability assistance was considered to be the right application domain. In 2021, ESIEE Paris, a school training students to become engineers with digital skills, created and opened a new teaching module to learn how to follow the principles of participatory design to improve the quality of a project.
