In order to integrate several time critical warning systems, e.g. Collision Warning and Lane Departure Warning, in the same vehicle one has to deal with the problem of warning management to not overload the driver in critical situations and to make sure that driver’s focus is directed to the right place. This paper presents INSAFES integration schemes to ensure these issues, and gives general as well as specific use cases based on warning systems integrated in one of INSAFES demonstrator vehicles. From these use cases are then requirements on warning management derived regarding prioritization schemes. The requirements concludes in a proposed extension of the warning management concepts derived in the AIDE project.

Presentation of graphical information is very important for blind. This information will help blind better understand surrounding world. The developed system is devoted for investigation of graphical information by blind user using a digitiser. SVG language with additional elements is used for describing of maps. Non-speech sounds are used to transfer information about colour. Alerting sound signal is issued near two regions boundary.

The goal of this project is to provide support for a system of geolocation powered by augmented reality, offering also advanced services such as, context awareness mobile applications and natural interaction related to the concept of ambient intelligent which favour the creation of intelligent environments whose services fit dynamically the demand, not always made explicit, of the user. A design and a development of a location system is obtained that provides extra services based on the positional information of the different system’s users. In this way, the user receives specific information of the place where he or she is located. This service is based on the Global Positioning System, from now on GPS. The aim with this platform is to locate, guide and give information to blind people, although it is open to any kind of people. It will allow the users to see information related to a place, to write comments about it and leave objects for the rest of the users to read and see. The information will be shown as a written text and as an oral one and in every moment the location of the user will be traced thanks to the virtual positioning of him or her on a map.

The paper describes: elements of a continuous improvement system in an enterprise, teamwork as an approach towards solving problems at workstations (especially problems concerning ergonomic issues) and methods and techniques used in ergonomic standards improvement at the stages of problem identification as well as search and implementation of the solutions. Requirements and conditions for efficient implementation are substantiated for improvements such as: training system, motivational system, system of applying and evaluation of applications, financial support of the implementation process and 5S program as a starting point for ergonomic improvements. Theoretical considerations will be illustrated with examples of improvements implemented in Polish enterprises.

States of hypovigilance cause severe accidents. Technical compensation can be provided by hypovigilance management systems (HVMS). In this paper, existing HVMS are discussed and the need for the development of a novel universal, multimodal HVMS is deducted. The development of such a system is presented and its application is illustrated with two application scenarios.

This paper elucidates and discusses some aspects of cultural adaptability which aid usability and universal access. We describe the concept, influence and Use Cases of cultural adaptability in driver information and assistance systems exemplified by a portable navigation system. Thereby, the reasons, advantages and problems of using adaptability regarding the driving safety and the driver preferences will be addressed. Differences in the amount of information for map display and in interaction behavior which depend on the background of the users (e.g. attitude, preference, skill etc.). We explain how cultural adaptability can improve usability and how it has a share in universal access. Finally, a short outlook into the future of adaptive driver information and assistance systems closes our reflections.

This paper describes a software architecture named “Gatos” engineered for intelligent decision making. The architecture is built on a distributed multi-agent system cougaar. Gatos provides a solution for sensor fusion. We propose using multiple sensors to monitor driver status, driving performance, and the driving environment in order to address bad driving behavior. Our approach for a Driving Monitor is based on both monitoring and regulating driver behavior. The system is designed to intervene and to interact with the driver in real time (if possible) to regulate their behavior and promote safe driving. A prototype is implemented using a driving simulator, but infrastructure buildup and new in-vehicle technologies make this a feasible solution for vehicles on the road.

The automotive industry are integrating more technologies into the standard new car kit. New cars often provide speech enabled communications such as voice-dial, as well as control over the car cockpit including entertainment systems, climate and satellite navigation. In addition there is the potential for a richer interaction between driver and car by automatically recognising the emotional state of the driver and responding intelligently and appropriately. Driver emotion and driving performance are often intrinsically linked and knowledge of the driver emotion can enable to the car to support the driving experience and encourage better driving. Automatically recognising driver emotion is a challenge and this paper presents a performance analysis of our in-car acoustic emotion recognition system.

This paper describes a study where drivers’ responses to an in-vehicle information system were tested in high and low density traffic. There were 17 participants in a study that was run using a driving simulator. Data was gathered for a comparison of how drivers react to an in-vehicle information system in low density traffic, complex traffic, and without system. Participants were also asked for their subjective evaluation of trust of the system and how they perceived it influenced their driving performance. Results show gender differences for both driving performance and attitude.

This paper presents a new interaction technique, which is based on arm posture recognition, for mobile computing devices to switch between different visualization modes seamlessly. We implemented a pedestrian navigation system on Pocket PC, which is connected to a GPS receiver and an inertial orientation tracker. In the global coordinate system, user’s position is tracked with GPS data, and in the local coordinate system user’s arm posture is mapped into two application dependent states with inertial orientation tracker data. Hence, natural interaction and different levels of information is provided by processing orientation tracker data. As unnecessary computation and rendering increase power consumption in small devices, we introduced another state to our system, which saves battery according to the user’s idle arm posture.
