Abstract

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 boyd-centered multimodal interaction for virtual reality applications.
