With the rapid emergence of 3D applications and virtual environments in computer systems; the need for a new type of interaction device arises. This is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. In other words, evolution of user interfaces shapes the change in the Human-Computer Interaction (HCI). In...

One measure of the communicative function of gestures is to test how speakers’ gestures are influenced by whether an addressee can see them or not, that is, by manipulating visibility between participants. We question traditional dependent variables (i.e., rate measures), suggesting that they may have been insufficient for capturing essential differences in the gestures speakers use in each con...

Abstract: In this article we present problem recognizing gestures and signs executed by hands. Gesture recognition is the process by which gestures formed by a user interact with the computer or is the element of the special signs language to convey meaning.We propose a methods for the recognition of hand gestures using Gabor wavelets (GW ), Radon transform (RT ) and texture features for gestur...

We propose an expressive performance model for celtic fiddle based on the analysis of audio and bowing gestures of real performances. Existing expressivity models deal with perceptual features such as timing deviations or dynamics, but in some cases perceptual features are not enough. We propose a model not only informed with perceptual features but also with bowing gestures which are acquired ...

This work introduces a pantomimic gesture interface, which classifies human hand gestures using unmanned aerial vehicle (UAV) behaviour recordings as training data. We argue that pantomimic gestures are more intuitive than iconic gestures and show that a pantomimic gesture recognition strategy using micro UAV behaviour recordings can be more robust than one trained directly using hand gestures....
