Illuminating the augmented reality stage: Assessment of lighting conditions for space exploration

Abstract

Augmented reality (AR) technology faces a prevailing challenge when dealing with harsh lighting environments, which are common in space. The study aims to evaluate the lighting compatibility for successful hand gestures using HoloLens 2, a device that utilizes AR technology for heads-up displays (HUDs), as a potential way to provide critical information to astronauts during extravehicular activities (EVAs). The study modulated luminance (dim, neutral, bright) and hand coverings (bare hand, white glove, black glove) to determine the HoloLens functionality. The results will inform design changes to support the astronaut experience by enhancing hand gesture recognition and reducing time wasted re-gesturing. By understanding the lighting requirements for HoloLens, we can improve the AR experience for future space missions. This study highlights the importance of considering lighting conditions in the development of AR technology, especially in challenging environments like space.
