For the most part, the case authoring tool is simple. The only aspect of it that may require some practice is manipulating case logic. Case logic allows the author to control all aspects of the case, from how the patient reacts to various actions to what it takes to “win” the case. VRpatients offers a free “VRpatients University” to help users get the most out of their case building. After a bit of practice, users rapidly acclimate to the building of case logic strings.
