This lecture discusses the concept of embodied interaction within the context of virtual reality (VR). It begins by defining virtual reality and its evolution, referencing key figures like Jaron Lanier. The instructor introduces Milgram's Virtuality Continuum, explaining the spectrum from real environments to fully virtual ones. The lecture emphasizes the importance of phenomenology in understanding how humans perceive and interact with their environment, highlighting the contributions of philosophers such as Heidegger and Merleau-Ponty. The distinction between 'ready-to-hand' and 'present-at-hand' modes of interaction is explored, illustrating how skilled actions become automatic. The instructor discusses the applications of VR in training, rehabilitation, and complex task learning, emphasizing its effectiveness in movement-based activities. Historical context is provided, detailing the origins of VR in military training and the development of head-mounted displays. The lecture concludes by asserting that VR can enhance embodied skills and facilitate faster perception-action loops, making it a valuable tool for various applications.
