This paper addresses the identi cation and representation of the variations induced by style for the synthesis of realistic and convincing expressive sign language gesture sequences. A qualitative and quantitative comparison of styled gesture sequences is made. This comparison leads to the identi cation of temporal, spatial, and stuctural processes that are described in a theoritical model of s...

This paper introduces the special issue of AI EDAM on the role of gesture in designing. It starts with the context of the papers submitted and a summary of the papers accepted. We then introduce gesture studies, one of the two main domains with which this Special Issue is concerned.We do not introduce design research: we suppose the readers of AI EDAM are familiar with this domain. After this g...

This paper describes the results of two studies conducted to determine the role of visual cues for a collaborative navigation task in a mixed-space environment. Both studies required a user with an exocentric view of a virtual room to navigate a fully immersed user with an egocentric view to an exit. The first study compares natural hand-based gestures, a mouse-based interface and an audio-only...

Out of the large range of human actions, gestures performed with the hands play a very important role during everyday life. Therefore, their automatic recognition is highly relevant for constructing userfriendly human-machine interfaces. This dissertation presents a new approach to the recognition of manipulative gestures that interact with objects in the environment. The proposed gesture recog...

With the advent of various video game consoles and tablet devices gesture recognition got quite popular to control computer systems. E.g. touch screens allow for an intuitive control of small 2d user interfaces with finger gestures. For interactive manipulation of 3d objects in a large 3d projection environment a similar intuitive 3d interaction method is required. In this paper, we present a d...

⎯ This paper is to present vision based motion analysis for human-robot interaction, which analyzes camera motion and human motion. Motion of camera is compensated by comparing edge features among consecutive image frames. Candidate regions of human motion are found by differencing between transformed t image and t-1 image. Human motion is finally decided by image features and motion analysis. ...
