In the lecture, the speaker discusses the different ways that humans perceive information and how these perceptions are applied in various fields, including augmented reality (AR) and virtual reality (VR) displays. The speaker explains that there are three main types of displays: handheld devices, AR displays, and VR displays. Within AR displays, there are two approaches: graphics overlaid on the lens and a camera-based approach, each with their own advantages and disadvantages. The speaker also discusses different methods for creating these displays, such as using microdisplays, mirrors, and lightfield displays, and how to create haptic feedback through vibrotactile devices and electrical muscle stimulation.The speaker stresses the importance of focusing on one modality at a time in order to effectively process and respond to sensory information, highlighting the concepts of space and variable in perception. The two response types discussed are focal and ambient channels, with direct attention referred to as focal channels and more general background processing referred to as ambient channels. Overall, the lecture provides a comprehensive overview of human perception and its applications in various fields, including AR and VR displays.
