Dear participants,

Welcome to the Human Machine Interfaces session of the IPROMS 2006 conference.

My name is Ze Ji and I am here to co-chair this session.

This session includes five papers discussing novel designs for new Human Computer Interfaces with different techniques.

Call for Papers for A Special Issue on "Human Computer Interaction Techniques"

Ze Ji — Mon, 26 Jun 2006 17:39:03 +0000

High-quality research papers are being sought for a Special Issue on "Multi-Modal Interfaces" to be published by an international archival journal.

This Session of the IPROMS 2006 Conference will give an idea of the type of topics of interest to the Special Issue. Other examples can be found in the "Tai-Chi session" at IPROMS 2005 and in the IPROMS 2005 proceedings published by elsevier.

The use of pattern matching for impact localization in solid object is a new attractive approach for the application of computer human interaction. In this paper, a coherence function technique is introduced for Tangible Acoustic Interface (TAI) using the Location Template Matching (LTM) approach. A simple workflow is proposed for the purpose of evaluating the performance of different TAI techniques and to investigate the effect of various parameters based on experimental data. Performance analysis shows that the method of magnitude squared coherence outperforms the traditional method of using time domain cross correlation for both of resolution and reliability aspects.

In this work we propose an in-depth study of elastic wave propagation in thin plates, based on the theory of Viktorov. We show that at the frequency range of interest and for modest plate thicknesses, the only waves that can be excited and propagate in the structure are guided waves (also called Lamb waves). As the elastic properties of the panel and the finger touch signature are usually unknown, therefore we propose two different methods for estimating them through simple experimental procedures (calibration). The first is an active method based on the use of a transducer, while the second one is a passive original method which infers the elastic properties of the board from the information given by a single tactile interaction. The obtained estimates are then used to simulate the propagation in the boards. Our approach is to implement the general solution of the elastic wave equation for infinite plates, and introduce the boundary conditions afterwards using a real-time beam tracer. We finally prove the effectiveness of the approach by comparing the predicted response of a finger touch with the measured one on a MDF (Medium Density Fiberboard) plate, showing how the active and the passive calibration procedures give comparable results.

This paper introduces a novel waveform –the wideband Cox comb waveform for the target tracking in air. It can provide an alternative estimation of the range and Doppler of the target as a new means for human computer interaction. The ambiguity function and matched filter are employed for the active signal analysis and processing. The simulation shows that the designed waveform, the cox comb waveform, can achieve a reliable result in terms of reverberation processing gain. The tracking system is combined time of flight technique and the Doppler tracking algorithm. The initial experimental results show that further requirement to improve the reverberation gain by the pulse design with the slow moving target.

There are several references to projects linked to the AmI concept in technical publications. These are mostly centred on applications linked to everyday situations concerning individuals: at home, in the street, in the car, in public places and relating to leisure. The AMILAB research group at TEKNIKER is analysing the technological, human and social needs and implications for AmI in the manufacturing field. For this aim we have set up a laboratory to spread the model of AmI to the area of manufacturing. This paper presents that Lab, the agent based architecture we have implemented as well as the application of machine learning techniques to identify the activities

Acoustic source localization for design of tangible acoustic interfaces

Acoustic source localization is important to the design and implementation of intelligent environments such as computer-human interaction systems. Different methods for multiple source localization are discussed and compared in this paper. The mathematical model of the method based on SRP-PHAT is presented for multiple sources localization under reverberant conditions. The PHAT are applied to suppress the reverberation from the environment. Global searching method and clustering technique are used to find the positions of multiple sources. MATLAB simulations and practical tests were carried out under real reverberant conditions. The simulation and test results show that the method is suitable for two acoustic source localization in reverberant environment.
