“…Lindeman et al devised a system that enables the visualization of the surrounding physical environment within the downward FoV by incorporating an aperture below the eyepiece lens, equipped with an adjustable transparency liquid crystal shutter [15,37]. While this system allows for the perception of the real environment in the downward FoV, it does not support image display.…”

“…Lindeman et al developed a system that presents information about the real environment in the downward view angle by installing an aperture under the eyepiece lens using an LC shutter with adjustable transparency [14,43] for typing a real keyboard in VR, for example. The real environment can be seen in the lower FoV with their system, but the virtual image cannot be presented in the aperture.…”

Fig. 1. Our head-mounted display (HMD) with a wide downward field of view (FoV). A) Side view. Blue: vertical FoV of the HTC VIVE. Part of the lower FoV is missing owing to the Liquid Crystal Displays (LCDs) housing. Orange: increased vertical FoV. Green: vertical FoV of a typical human. B) The added LCD and Fresnel lens. C) Original FoV of the HTC VIVE (approx. 70×70 [deg]). The user's hand is visible but not the lower limbs and body. D) FoV of the prototype (approx. 70×130 [deg]). The user's lower limbs and body and the ground are all visible at the same time.

Robot-assisted surgery platforms are utilized globally thanks to their stereoscopic vision systems and enhanced functional assistance. However, the necessity of ergonomic improvement for their use by surgeons has been increased. In surgical robots, issues with chronic fatigue exist owing to the fixed posture of the conventional stereo viewer (SV) vision system. A head-mounted display was adopted to alleviate the inconvenience, and a virtual vision platform (VVP) is proposed in this study. The VVP can provide various critical data, including medical images, vital signs, and patient records, in three-dimensional virtual reality space so that users can access medical information simultaneously. An availability of the VVP was investigated based on various user evaluations by surgeons and novices, who executed the given tasks and answered questionnaires. The performances of the SV and VVP were not significantly different; however, the craniovertebral angle of the VVP was 16.35° higher on average than that of the SV. Survey results regarding the VVP were positive; participants indicated that the optimal number of displays was six, preferring the 2 × 3 array. Reflecting the tendencies, the VVP can be a neoconceptual candidate to be customized for medical use, which opens a new prospect in a next-generation surgical robot. Graphical Abstract
