In the 4th winter school, we focus on technologies for extending the human senses and cognition. We look at the intersection of scientific fields for opportunities to amplify our abilities as humans in perceiving our surroundings. We explore creating new senses such as a sense of location and a sense of emotional intelligence besides the five classical ones (vision, audition, gustation, olfaction, and somatosensation). Through a series of interactive activities, we capture innovative use cases while exchanging methodologies on how to conduct impactful research.
