ABSTRACT: The goal of the ROBOHELPER project is to design and develop robotic assistants that could help
the elderly live independently. In the first phase of this project, we are focusing on the multimodal interface required for the human to communicate with the robot. I will first describe the data collection of human-human interactions we carried out with elderly subjects. I will then discuss the pronominal and deictic reference resolution model we developed. A novel aspect of our model is that it includes "haptic-ostensive" actions, namely, gestures that involve manipulating an object. Our results show that the presence of simultaneous gestures improves coreference resolution for personal and deictic pronouns. I will conclude by illustrating current work on recognizing haptic gestures on the basis of the pressure sensor signals we collected.
