An acoustic interface for triggering actions in virtual environments
نویسندگان
چکیده
Currently one of the main research issues in Human Computer Interaction (HCI) is to develop more intuitive, multimodal and natural interfaces. Among them, the interface for triggering simple actions or selecting objects in virtual environments (VEs) is one of the concerned areas. In this paper we describe an acoustic interface which uses finger snap or hand clap sounds as the input command to initiate events for VE applications. We developed a sophisticated algorithm based on the wavelet transform and neural network techniques, which separate the environment noise from the snap and clap sound. The acoustic interface could be integrated with other interfaces like optical tracking systems to provide a more natural, easy-to-use, efficient and body-centered multimodal interaction for virtual reality applications. Keyword: Human Computer Interface, Acoustic Interface, Wavelet Algorithm, Neural Network, Virtual Environment, Natural and Multimodal Interfaces.

An Acoustic Study of Emotivity-Prosody Interface in Persian Speech Using the Tilt Model
This paper aims to explore some acoustic properties (i.e. duration and pitch amplitude of speech) associated with three different emotions: anger, sadness and joy against neutrality as a reference point, all being intentionally expressed by six Persian speakers. The primary purpose of this study is to find out if there is any correspondence between the given emotions and prosody patterning in P...
متن کاملA High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients
This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...
متن کاملSharing and immersing applications in a 3D virtual inhabited world
In a remote computer-mediated collaboration, co-workers have a limited perception of each other: they loose the sense of immersion. To deal with this problem, some collaborative environments as NetMeeting [1] use videoconferencing. Leung [2] claims that these systems lack the sense of immersion because every participant sees others in separate windows and doesn't know who is acting. In order to...
متن کاملConfigurable Design of Multimodal Non Visual Interfaces for 3D VE's
3D virtual environments (VE) require an advanced user interface to fully express their information contents. New I/O devices enable the use of multiple sensorial channels (vision, hearing, touch, etc.) to increase the naturalness and the efficiency of complex interactions. Haptic and acoustic interfaces extend the effective experience of virtual reality to visually impaired users. For these use...
