We live in a world of designed experiences. From the menu at your favorite neighborhood restaurant to the sidewalks you use to get across campus to the computer rendering this text--all have been carefully planned to offer a designed experience. In my lab, we are interested in designing experiences that cross between bits and atoms--the virtual and the physical. For example, we've built sensors that can classify individual water fixture events across an entire home from a single sensing point, an electronic textile athletic jersey that displays the performance of the wearer (e.g., speed, heartrate) in real-time, and a massive online crowdsourcing system that combines computer vision with human computation to semi-automatically identify inaccessible areas of the physical world for people in wheelchairs. These projects embody my lab's ethos of designing for a social purpose whether it's environmental sustainability, universal accessibility, or health/fitness. We believe that through research and design, we can enhance and augment human ability and, along the way, increase our own abilities to make a difference in the world.
