Our goal is to develop an interface for older people to effectively communicate with a robotic assistant so that they can safely remain living in their home. We are devising a multimodal interface since people communicate with one another using a variety of verbal and non-verbal signals, including haptics, i.e., physical interactions. We view haptics as an(More)
In this paper we describe our progress towards understanding human communication through physical interaction. We describe a classification algorithm that can recognize four classes of actions that frequently occur during collaborative manipulation of planar objects. These actions were selected based on a user study involving dyads of elderly and care-giver(More)
The RoboHelper project has the goal of developing assistive robots for the elderly. One crucial component of such a robot is a multimodal dialogue architecture, since collaborative task-oriented human-human dialogue is inherently multimodal. In this paper, we focus on a specific type of interaction, Haptic-Ostensive (H-O) actions, that are pervasive in(More)
This paper describes the development and evaluation of an interactive educational program, Tooth Placement and Identification Coach (ToothPIC). The program uses a game-based learning paradigm and 3D visualization techniques to allow first year dentistry and hygiene students to get familiar with dental anatomy. It provides an interactive and stimulating(More)
Atomically thin semiconductors are one of the fastest growing categories in materials science due to their promise to enable high-performance electronic and optical devices. Furthermore, a host of intriguing phenomena have been reported to occur when a semiconductor is confined within two dimensions. However, the synthesis of large area atomically thin(More)
Novel physical phenomena emerge in ultra-small sized nanomaterials. We study the limiting small-size-dependent properties of MoS2 monolayer rhombic nanoflakes using density-functional theory on structures of size up to Mo35S70 (1.74 nm). We investigate the structural and electronic properties as functions of the lateral size of the nanoflakes, finding(More)
This paper presents an investigation of human physical interaction. In particular, we describe how data from pressure sensors mounted on a glove worn by a human can be mapped to manipulation actions; the actions can in turn be used to interpret physical interaction during elderly care. The work is part of the RoboHelper project, which aims to build a(More)
The RoboHelper project aims at building an effective and user friendly communication interface for assistive robots that can help the elderly live independently at home. Such communication interface should incorporate multiple modalities of communication, since collaborative task-oriented human-human communication is inherently multimodal. Data was(More)
