Neuropsychological functions of nonverbal hand movements and gestures during sports

Functions of three open-palm hand gestures

INTRODUCTION Kendon distinguishes between two different types of gestures: " 'Pragmatic' gestures that indicate type of speech act or aspects of discourse structure and 'substantive' gestures that express utterance content " (1995:247). He further defines 'pragmatic gestures' as playing " modal, performative and parsing functions " as well as " interpersonal functions " (Kendon, 2004:159). A ge...

Comparison of Plantar Dynamics During Four Sports Gestures in Rugby Players

Background. Four of the most relevant gestures in rugby (RU) are the pass, the tackle, the line out, and the scrum. RU is the third most common contact sport on the planet, and being a fast-paced collision game and carries a high risk of injury. Objectives. To describe and compare plantar dynamics during four sports gestures in rugby players through speed, strength, and balance. Methods. Twen...

Hand Gestures Classification with Multi-Core DTW

Classifications of several gesture types are very helpful in several applications. This paper tries to address fast classifications of hand gestures using DTW over multi-core simple processors. We presented a methodology to distribute templates over multi-cores and then allow parallel execution of the classification. The results were presented to voting algorithm in which the majority vote was ...

Recognizing Hand Gestures

This paper presents a method for recognizing human-hand gestures using a model-based approach. A Finite State Machine is used to model four qualitatively distinct phases of a generic gesture. Fingertips are tracked in multiple frames to compute motion trajectories, which are then used for nding the start and stop position of the gesture. Gestures are represented as a list of vectors and are the...
