Logging all the touch operations on Android

Touch operation has already become a common technique, and will be adopted to most electrical appliances in the future. Therefore, we suppose that a user's touch operation will be one of important contexts for realizing the future context-aware system. Through observation of the user's touch operation, a system could estimate the user's emotion, skill, etc. In this demonstration, we exhibit our system for logging all the touch operations on Android. In addition to the logging, our system can analyze and visualize several popular touch operations.
