In augmented reality, we integrate virtual content with the real world. This requires alignment between the virtual content and the real world. Although the virtual content can address all of our senses, in augmented reality research the focus has been on sight because of it being a dominant sense and because many useful augmented reality applications can be designed from a vision-oriented point of view. Virtual content can as well address the tactile, gustatory, olfactory, and auditory senses, address multisensorial experiences, and can induce crossmodal experiences. Human perception is multisensorial. What does this mean if we introduce virtual humans in augmented reality? In this talk, we consider several types of problems and challenges associated with alignment as we move away from more traditional, only the sight-sense addressing AR applications.
