A Real-World Grounded Usability Evaluation of VR Interaction Techniques Across Discrete, Spatial, and Continuous Tasks

With the growing use of virtual reality (VR), interaction techniques need to be evaluated across different task demands and in relation to real-world performance. This study compares four VR interaction techniques—Direct Controller, Hand Tracking, Raycasting, and Wrist Rotation—across discrete (text typing), spatial (t...
