The number of in-vehicle comfort functions is increasing as are the number of maneuverable buttons in the vehicle. Haptic interfaces for in-vehicle functions are now commercially available. Thus, haptic interfaces are a realistic approach to an aesthetically and ergonomically improved HMI. That is, without increasing the visual load on the driver. However, as often is the case with new technologies, some haptic interfaces might have been put into operation before being studied and evaluated sufficiently, e.g. being potentially \"safety critical\". The objective of this paper is to contribute in bridging the gulf between application and research concerning implementation of haptic interfaces for in-vehicle comfort functions. Two studies are reported in the paper. Firstly, a simulator study where a haptic/graphic interface is evaluated against a traditional interface with maneuverable buttons for in-vehicle comfort functions. Secondly, an experimental study that still is in the planning phase. The study aims at investigating the interaction effects between haptic and visual feedback in a haptic/graphic interface.","PeriodicalId":431267,"journal":{"name":"The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003.

Using some basic equations from the field of kinesiology, a procedure was developed in order to determine the optimal position of a muscle in various musculoskeletal configurations found in the human body. This procedure takes into account the artificial muscle characteristics and finds the origin and insertion point of the muscle by optimizing the maximum range of motion and the output torque produced at the joint. Currently available artificial muscles such as McKibben air muscles, Shape Memory Alloys and electroactive polymers are reviewed. Functional models of the SMA and McKibben muscles were presented and used in the optimization procedure.","PeriodicalId":431267,"journal":{"name":"The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003.

A PBVE was constructed to synthesize the corresponding view when navigating. Users can interact with PBVE through augmented 3D graphic objects. Unlike traditional image-based virtual environment (VE) systems in which the functions of presenting 3D geometry and human-computer interaction (HCI) are very limited, the proposed PBVE system utilized augmented reality technology to enable users to interactively present 3D geometry. Therefore, the HCI ability is significantly increased and the gap between passive planar navigation and interactive human-VE three-dimensional navigation is eliminated.","PeriodicalId":431267,"journal":{"name":"The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003.

For instance, HLA object-attribute based ownership management only allows joint manipulation in a constraint-based solution. The purpose of this research effort is to realize joint manipulation management in CVE. This paper begins with a discussion of interaction requests and interaction model and proceeds to describe three generic approaches for joint manipulation management: Constraint-based, Synchronized and Non Synchronized.","PeriodicalId":431267,"journal":{"name":"The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003.

Data is acquired from a Patriot digital pad, using the Windows Pen API. The signatures are analyzed dynamically by considering their spatial and time domain characteristics. A stroke-based feature extraction method is studied, in which strokes are separated by the zero pressure points. Between each pair of signatures, the correlation comparisons are conducted for strokes. A significant stroke is discriminated by the maximum correlation with respect to the reference signatures. The correlation value and stroke length for the significant strokes are extracted as features for identifying genuine signatures against forgeries. The membership function and classifier are modeled based on the probabilistic distribution of selected features. Experimental results were obtained for signatures from 20 volunteers. The current 6-feature based signature verification system was calculated to have a false accept rate of 1.67% and false reject rate of 6.67%.","PeriodicalId":431267,"journal":{"name":"The 2nd IEEE Internatioal Workshop on Haptic, Audio and Visual Environments and Their Applications, 2003.

Mean Opinion Score (MOS) is used as an index for speech quality and is measured by Perceptual Evaluation of Speech Quality (PESQ) algorithm. These effects on speech quality are assessed in the equipment impairment factor domain and then formulated into the E-model.
