My current research interests are in intelligent user interfaces (IUI), including activity recognition-driven interfaces such as sketch, motion, and navigation. My recent primary focus has been on developing and deploying pen-driven intelligent tutoring systems for improving remote classroom instruction and homework study through instructor-emulated assessment and interactive visual feedback. My research efforts have been published at highly-visible computing conferences and journals such as IAAI, CHI, MobileHCI, TiiS, and IJHCS.
