Advancements and Challenges in Virtual Reality: A Comprehensive Overview of Tracking and Display Technologies
Qikun Zhang · 2024
Virtual Reality (VR) has evolved significantly from its nascent stages in the mid-20th century to its current state, characterized by sophisticated tracking and display technologies. This manuscript delves into the historical progression of VR, highlighting key milestones and innovations. It provides an in-depth analysis of tracking systems, including wireless tracking, inertial tracking, and sensor fusion, discussing their operational principles, advantages, and limitations. Additionally, the manuscript explores various display technologies such as Liquid Crystal Display (LCD) and Light Emitting Diode (LED) screens, emphasizing their impact on the user experience. Key features affecting VR immersion, including resolution, frame rate, screen curvature, and device weight, are examined. The paper concludes with a discussion on future trends and the potential for specialized VR systems designed to accommodate users with specific needs, such as severe myopia and color blindness.
