Given a user has some interaction impairments or s/he is in a situation that causes an interaction impairment (i.e. noisy environment has the same consequences as hearing impairment), another modality is to be used or adapted to compensate this impairment. As sound has other interaction characteristics than graphical user interface elements (e.g. information can not be presented in parallel, but sequentially), rules for substituting some modalities through others are described.

The aim was to firstly evaluate the usefulness, ease of use, usability and user experience of travellers and service providers in using the MaaS enabling mobile application and Service Registration Tool, respectively and secondly to evaluate the user experience and adoption of both solutions in in real-life continuous use for 6 months in 5 European cities (Amsterdam, Athens, Prague, Rome, Salzburg) for national and cross-border journeys. This paper presents a multifaceted evaluation framework for the evaluation of a MaaS mobile application by travellers and preliminary findings from the user experience tests.

In parallel, a series of State of the Art cooperative safety and automated solutions do not exploit data directly originating from the infrastructure and the environment, failing, in this way, to have the most reliable possible safety critical information that is vital to the optimum fulfillment of their objectives; that being primarily the increase of traffic safety. SAFE STRIP (SAFE and green Sensor Technologies for self-explaining and forgiving Road Interactive aPplications) EU funded project envisions to simultaneously address those challenges by introducing a revolutionary C-ITS approach through the placement of low-cost innovative sensorial frameworks on the road pavement surface itself in order to acquire reliable and lane specific traffic and environmental information that is directed through I2X (Infrastructure to Everything) communication to all types of vehicles. The current manuscript presents the vision and objectives, the core use cases serving as the proof of concept of the technological solution built, the implementation approach towards delivering the solution and, finally, the multilayered validation approach anticipated by the Consortium towards delivering a prototype of an as much as possible high technological readiness as well as C-ITS functions evidencing its value.

One of the major aims of the PReVAL project is the assessment of the work performed in the PReVENT subprojects. This deliverable reviews the evaluation results from the different PReVENT subprojects. The deliverable is both a deliverable for the PReVAL subproject and for the PReVENT IP (IP D10 “Validation results of first phase PReVENT projects”).

An agile and dynamic approach is adopted in three evaluation phases, starting with formative evaluations with five internal implementers leading to more summative techniques towards the final evaluation phase where more ni¾?=i¾?25 and external professionals will use the tools and resources available in the project's repository DeveloperSpace to improve and enhance their own products and services. The evaluation approach for the implementers considers three dimensions: a the project's Key Performance Indicators KPIs, b technical validation activities prior evaluation, and c three evaluation phases followed by a final impact assessment.

It responds to the weaknesses that have been recognised in the driving simulator validity research field, with respect to the validity of the experimental process being followed as well as to the methodology applied for the comparative analysis of the collected measurements. A case study concerning a semi-dynamic driving simulator is presented. The research hypotheses, the experimental plan and the basic conditions of the analysis methodology that have supported it are described. Trials have been conducted in a semi-dynamic simulator and on-road with 36 drivers (12 trainees, 12 novice and 12 experienced), in “following vehicle” and “free driving” scenarios in highway, rural and urban roads in order to prove the established research hypotheses for a series of driving behaviour metrics.

The aim of this paper is to substantiate the introductory presentation in the session "Facing Virtual Environments with innovative interaction techniques" at HCI 2007. Although VEs and multimodal interfaces tried to make Human-Computer-Interaction as natural as possible, they have shown serious usability problems. We describe concepts to aid users in supporting their personal cognitive and perceptual capabilities, where the Virtual Environment will adapt dynamically and in real-time to the users' physiological constitution, previous behaviour and desires. With our concept, human performance can be significantly enhanced by adapting interfaces and environments to the users' mental condition and their information management capacity. Health and usability problems caused by stress, workload and fatigue will be avoided. We intend to encourage discussions on this topic among the experts, which are gathered this session.

Cloud4all is an international collaborative effort to build and test key elements of the Global Public Inclusive Infrastructure (GPII) (http://gpii.net/). Cloud4all/GPII aims to develop a complete new paradigm in accessibility, by replacing adaptation of individual products and services for a person with automatic-personalisation of any mainstream product or service, using cloud technologies to activate and augment any natural (built-in) accessibility the product or service has, based on a profile of the user's needs (http://www.cloud4all.info). A first step in the implementation path that has already started to be followed in the project has been the identification of those case studies that would be of primary concern for Cloud4all and the overall GPII.

In the same sense, it is not known under which conditions such an approach would be valid to follow. An experimental plan has been developed for proving such a method which has been established for accommodating the transferability of driving simulator results into real traffic conditions. This manuscript discusses the selected conditional parameters, the reasons of their selection in contradiction to others, the corresponding research hypotheses and the results that reveal how each parameter contributes to the different achieved levels of transferability for the specific type of driving simulator.

Users participating in the first out of the three in total evaluation rounds scheduled within the project represented all user clusters targeted by the project. The emerging results, which are considered overall positive, will constitute the basis for the optimisation to be held until the next evaluation round of the project.
