Development and Human Factors Considerations for Extended Reality Applications in Medicine: The Enhanced ELectrophysiology Visualization and Interaction System (ĒLVIS).

With the rapid expansion of hardware options in the extended realities (XRs), there has been widespread development of applications throughout many fields, including engineering, entertainment and medicine. Development of medical applications for the XRs have a unique set of considerations during development and human factors testing. Additionally, understanding the constraints of the user and the use case allow for iterative improvement. In this manuscript, the authors discuss the considerations when developing and performing human factors testing for XR applications, using the Enhanced ELectrophysiology Visualization and Interaction System (ĒLVIS) as an example. Additionally, usability and critical interpersonal interaction data from first-in-human testing of ĒLVIS are presented.
