확장현실에서의 저시력 사용자를 위한 Spread 인터랙션 기반 확대 디스플레이

초록

Recent advancements in augmented reality (AR) and virtual reality (VR) technologies have increased the use of head-mounted displays (HMDs) like Meta Quest and Apple Vision Pro. These technologies are widely used in gaming, entertainment, education, healthcare, architecture, industry, and manufacturing, with expanding potential. A key element these devices share is displaying text on virtual screens and providing users with selectable options. However, users with reduced vision struggle to recognize and select distant objects or small text in HMD environments. This study proposes a novel interaction method using a spread gesture, which involves moving the index finger and thumb apart to magnify the desired area. This method provides an additional magnified screen in the lower right corner of the user’s view, aiding in text recognition and element selection.
