Virtual Reality to support healthcare

The realism of the scenario has been greatly improved by integrating more steps and using more realistic 3D
models. The user-centered approach adopted throughout this project allowed the prototype to be iteratively
shaped according to the preferences and needs of HEdS-FR students. The prototype also allows students to
practice the blood testing scenario in almost any environment by teleporting to move around the scene. A second
mode allows them, in specific rooms at HEdS-FR, to practice the scenario by walking to move around the scene
without having to worry about the real world. Students also have the opportunity to play the scenario using hand
tracking or controllers according to their personal feelings. If they choose to play with the controllers, they are also
able to switch the visualization of the controllers from “Hands only” to “Hands and controllers” and vice versa at
any time during the scenario. Findings of this project could help future studies to make decisions on the design of
similar applications on various aspects such as hand tracking, AV or controller visualization. Some generic
implementations (compatible with hand tracking and controllers) developed during this project, such as
teleportation or sockets, may also benefit to the VR development community since none of this kind could be
found online. Even if real training remains essential to learn technical gestures, students who participated in the
final user tests confirmed that the prototype could really help them to become more aware of hand hygiene while
learning/testing their knowledge on the blood testing procedure.
