Abstract:
This paper proposes a method for improving touchscreen usability by anticipating user motions. Reaction speed and simple structure are important for good touchscreen usability. With this in mind, we present a system that can estimate a desired position for user motion by anticipating a motion several time steps ahead, using only sensors attached to the touchscreen. User motion that changes suddenly may not have the Markov property. We present here a novel methodology based on an Auxiliary Particle Filter (APF) with parameter estimation to deal with this issue. User motion is anticipated by regarding the motion in terms of parameters. We demonstrate the validity of our approach through experiments.
