PURPOSE Research has shown that hand gestures affect comprehension and production of speech at semantic, syntactic, and pragmatic levels for both native language and second language (L2). This study investigated a relatively less explored question: Do hand gestures influence auditory learning of an L2 at the segmental phonology level? METHOD To examine auditory learning of phonemic vowel leng...

Some groups of handicapped persons cannot reliably move the mouse and do the necessary operation on it to control the computer. However they can do some 3-d hand motions. Variety of tools has been presented for these users to interact with computer. Hand gesture recognition is one of the proper methods for this purpose. This paper presents a new algorithm for hand gesture recognition. In this a...

This paper discuss of basic of gesture recognition (GR) concept its various types, methods and approaches for recognizing a gesture as well as its application. Basically Gesture Recognition means identification and recognition of gestures of body motion, which can originate from face or hand. Gesture recognition it is also a topic in computer science engineering and language technology which in...

For the whole matching cannot handle partial occlusion and lack of specificity, a new method using PolarRadius-Invariant-Moment, which is based on Key-Points to extract features for target’s shape recognition, is presented in this paper. Firstly, key-points of the hand shape are extracted through discrete curve evolution method. Secondly, Polar-Radius-Invariant-Moment based on KeyPoints is used...

Research suggests that speech-accompanying gestures influence cognitive processes, but it is not clear whether the gestural benefit is specific to the gesturing hand. Two experiments tested the "(right/left) hand-specificity" hypothesis for self-oriented functions of gestures: gestures with a particular hand enhance cognitive processes involving the hemisphere contralateral to the gesturing han...

In this paper we present a system called Gesture User Interface (GestureUI) to recognize static gestures of the Brazilian Sign Language (Libras) in real-time out of a continuous video stream using the depth information captured by a Kinect controller. We focus on handling small sets of gestures (A,E,I,O,U) and (B,C,F,L,V), processing them in two steps: Segmentation and Classification. For the S...
