Abstract: Vision is our most developed sense and one upon which we rely to make many decisions, conscious or otherwise. Many of our everyday interactions, such as driving a car, greeting familiar faces on the street, or deciding which dish to order at a restaurant, are guided by our visual sense. For the most part, this works well. But sometimes we are reminded of our visual system’s limitations and surprising behavior through optical illusions that exploit misjudgments in size, distance, depth, color and brightness, among many others. This lecture presents and explains a diverse collection of visual perception phenomena that challenge our common knowledge of how well we detect, recognize, compare, measure, interpret, and make decisions upon the information that arrives at our brain through our eyes. It also explains the relationships between the latest developments in human vision research and emerging technologies, such as: self-driving cars, face recognition and other forms of biometrics, and virtual reality. After seeing a large number of examples of optical illusions and other visual phenomena, this talk will make you wonder: can you really trust what you see?
