“…Results showed a trend whereby the participants perceived the mobile AR solution to be more usable than the one with the ophthalmoscope replica but less usable when compared to the EYEsi DOS. Another example employs a tangible user interface and an AR-based approach that allows multiple trainees to interact with an eye fundus displayed on both the screen and mobile devices [12].…”

“…VR-and AR-based DO simulators require input devices that are representative of the direct ophthalmoscope, and the choice of input device can have a significant impact on the ease of use of the entire simulation. The potential impact of interaction techniques on VR-and AR-based DO simulators has led us to explore usability issues associated with mobile AR used in combination with a Styrofoam head, and a 3D-printed direct ophthalmoscope replica as alternative tangible user interfaces [11], tabletop displays for multiuser visualization, interaction and augmentation [12], and early prototyping of VR DO eye examination [4]. Despite recent advances in custom-made user interfaces employing 3D printing and open electronics, virtual simulators continue to employ off-the-shelf VR controllers and gestural inputs that may impact usability.…”

Direct ophthalmoscopy (DO) is a medical procedure whereby a health professional, using a direct ophthalmoscope, examines the eye fundus. DO skills are in decline due to the use of interactive diagnostic equipment and insufficient practice with the direct ophthalmoscope. To address the loss of DO skills, physical and computer-based simulators have been developed to offer additional training. Among the computer-based simulations, virtual and augmented reality (VR and AR, respectively) allow simulated immersive and interactive scenarios with eye fundus conditions that are difficult to replicate in the classroom. VR and AR require employing 3D user interfaces (3DUIs) to perform the virtual eye examination. Using a combination of a between-subjects and within-subjects paradigm with two groups of five participants, this paper builds upon a previous preliminary usability study that compared the use of the HTC Vive controller, the Valve Index controller, and the Microsoft HoloLens 1 hand gesticulation interaction methods when performing a virtual direct ophthalmoscopy eye examination. The work described in this paper extends our prior work by considering the interactions with the Oculus Quest controller and Oculus Quest hand-tracking system to perform a virtual direct ophthalmoscopy eye examination while allowing us to compare these methods without our prior interaction techniques. Ultimately, this helps us develop a greater understanding of usability effects for virtual DO examinations and virtual reality in general. Although the number of participants was limited, n = 5 for Stage 1 (including the HTC Vive controller, the Valve Index controller, and the Microsoft HoloLens hand gesticulations), and n = 13 for Stage 2 (including the Oculus Quest controller and the Oculus Quest hand tracking), given the COVID-19 restrictions, our initial results comparing VR and AR 3D user interactions for direct ophthalmoscopy are consistent with our previous preliminary study where the physical controllers resulted in higher usability scores, while the Oculus Quest’s more accurate hand motion capture resulted in higher usability when compared to the Microsoft HoloLens hand gesticulation.
