A new interface for visualizing and analyzing percussion gestures is presented, proposing enhancements of existing motion capture analysis tools. This is achieved by offering a percussion gesture analysis protocol using motion capture. A virtual character dynamic model is then designed in order to take advantage of gesture characteristics, yielding to improve gesture analysis with visualization...

With the increasing role of computing devices, facilitating natural human computer interaction (HCI) will have a positive impact on their usage and acceptance as a whole. For long time, research on HCI has been restricted to techniques based on the use of keyboard, mouse, etc. Recently, this paradigm has changed. Techniques such as vision, sound, speech recognition allow for much richer form of...

Co-thought gestures are hand movements produced in silent, noncommunicative, problem-solving situations. In the study, we investigated whether and how such gestures enhance performance in spatial visualization tasks such as a mental rotation task and a paper folding task. We found that participants gestured more often when they had difficulties solving mental rotation problems (Experiment 1). T...

BACKGROUND Previous research has emphasized the importance of gesture in early communicative development. These studies have reported that gestures are used frequently during the first two years of life and may play a transitional role in the language acquisition process. Although there are now numerous descriptions of the relationship between gesture and the developing language system in typic...

The evolution of technology has risen new possibilities in the so called Natural User Interfaces research area. Among distinct initiatives, several researchers are working with the existing sensors towards improving the support to gesture languages. This article tackles the recognition of gestures, using the Kinect sensor, in order to create a gesture library and support the gesture recognition...

In order to infer intent from gesture, a rudimentary classi_cation of types of gestures into _ve main classes is introduced. The classi_cation is intended as a basis for incorporating the understanding of gesture into human-robot interaction (HRI). Some requirements for the operational classi_cation of gesture by a robot interacting with humans are also suggested.

This paper introduced a method of building and fixing a digitalized model of human hand gesture through contour analysis of the hand’s orthographic projection. Via contour analysis the fingers and palm on the projection are located and their quantized characters are calculated. The model is used in a gesture recognition method, where the articulation is of core concern. Thus the method is adapt...
