Creating gestural recognition system is a challenging task which requires skills and updated applications. It is required for designer to be skillful and innovative in order to create interesting and acceptable gestures. Gesture Recognition Design Toolkit (GRDT) is set of tools designed to simplify the gesture creation process for non experts. From designing a new gesture, to suggesting the bes...

Gesture recognition is to recognizing meaningful expressions of motion by a human, involving the hands, arms, face, head, and/or body. Hand Gestures have greater importance in designing an intelligent and efficient human–computer interface. The applications of gesture recognition are manifold, ranging from sign language through medical rehabilitation to virtual reality. This exploratory survey ...

This paper used ultrasound technology to examine the plain and palatalized taps in Japanese. Six participants of Japanese produced nonsense words containing /ɾ/ and /ɾ/. The mid-sagittal contours were compared in three intervocalic contexts: a_a, o_o, u_u. The results showed that /ɾ/ had a great deal of variability around the tongue dorsum. This suggests that /ɾ/ lacks a dorsal gesture; unlike ...

How to recognize the shape gesture for new human-computer interface without controller required and bring entertainment, games industries and information appliances in new ways. In this paper, we would illustrate a real-time hand gesture recognition system by using shape context matching and cost matrix. The shape context is taken as a basis description for shape matching. It can be regarded as...

Considering the technological advances in touch-based devices, gesture-based interaction has become a prevalent feature in many application domains. Information systems are starting to explore this type of interaction. Currently, gesture specifications are hard-coded by developers at the source code level, hindering its reusability and portability. Similarly, defining new gestures in line with ...

In development, children often use gesture to communicate before they use words. The question is whether these gestures merely precede language development or are fundamentally tied to it. We examined 10 children making the transition from single words to two-word combinations and found that gesture had a tight relation to the children's lexical and syntactic development. First, a great many of...

This paper describes work in progress on the development of a plugin automatic gesture recogniser intended for a human-computer natural speechand-gesture dialogue interface module. A model-based approach is suggested for the gesture recognition. Gesture models are built from models of selected finger tip trajectories as traversed through physical 3D space of the human gesturer when performing t...

A gesture-based interface involves tracking a moving hand across frames, and extracting the semantic interpretation corresponding to the gesture. This is a difficult task, since there is a change in both the position as well as the appearance of the hand. Further, such a system should be robust to the speed at which the gesture is performed. This paper presents a novel attempt at developing a h...

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co-vary with other non-verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behavior...

The coordination of speech with gesture elicits changes in speakers' problem-solving behavior beyond the changes elicited by the coordination of speech with action. Participants solved the Tower of Hanoi puzzle (TOH1); explained their solution using speech coordinated with either Gestures (Gesture+Talk) or Actions (Action+Talk), or demonstrated their solution using Actions alone (Action); then ...
