The Smart Computer Interfaces for Future Interactions (SciFi) Lab at Cornell University designs, develops, and evaluates intelligent sensing systems, with an emphasis on wearable forms, to facilitate natural and novel information exchange between humans, computers, and the environment. By leveraging the vast amounts of data obtained from these systems, the lab explores advanced signal processing, machine learning, and artificial intelligence techniques to advance key applications in activity recognition, health sensing, and natural user interfaces. The lab's ultimate goal is to enable computers of various form factors to seamlessly understand and predict human behaviors and intentions, providing users with support whenever and wherever they need it.
