Summary: His paper presents a tool facilitating developers of user interfaces (UIs) to experience accessibility limitations that can be posed from various disabilities during the interaction of impaired users with their developments. In this respect, various aspects of visual, hearing, physical and cognitive impairments have been modelled through filters providing approximate, yet, realistic simulations over them. These filters have formed the basis for the developed tool, which can be used either on its own (as a standalone application), or be embedded in the NetBeans Integrated Development Environment. The tool, named DIAS, allows for impairment simulations to be performed over Java, mobile and web applications. Moreover, it integrates two of the most common assistive technologies (ATs), namely a screen reader and a magnifier. As a result, developers of UIs can not only experience how interaction would be affected from various impairments, but they can also understand how their developments would be perceived by impaired users through an AT. This work aims to provide an integrated, practical solution for impairment simulation, which could be easily adopted by developers, thus realistically increasing the possibilities for the future development of interactive applications that are more accessible to users with disabilities.

Summary: This paper presents novel subject-dependent biosignal features, with a view towards increasing the effectiveness of automatic psychological stress detection. The features proposed in this work focus on suppressing between-subject variability that typically appears in biosignals like the skin conductance (SC) and the electrocardiogram (ECG), and degrades the performance of relevant emotion recognition (ER) systems. For this purpose, the proposed features employ filtering of input signals, on the basis of "rest signatures' calculated from each subject's baseline recordings. These signatures are biosignal transformations capable to express each individual's baseline deviation from signal templates, which would ideally be applied during rest. The proposed subject-dependent features, extracted from SC and ECG modalities, were found capable to significantly increase automatic stress detection accuracy over a multi-subject (N=24) data set, collected through an experiment of natural stress induction. They provided accuracy at the level of 95%, significantly improved to the respective result (86.05%) taken from common SC and ECG features that have been typically used in the past. They appeared also similarly effective in automatic frustration detection over a further dataset. The results of the present work indicate that the proposed subject-dependent features, can lead to significant advances in the performance of future relevant ER systems.

Summary: Enhancing HCI systems with the capability to detect user's frustration and respond appropriately is a significant challenge. In this line, biosignal features based on the theory of orthogonal Krawtchouk and Legendre moments are assessed in the present work over their ability to enhance accuracy in automatic detection of frustration, which is induced through HCI, during video-game playing. Experimental evaluation, conducted over a multi-subject dataset over frustration detection showed that conventional features, typically extracted from Galvanic Skin Response and Electrocardiogram in the past, achieved correct classification rate (CCR) of 83.59%. Fusing these conventional features with moment-based ones extracted from the same modalities resulted to significantly higher accuracy, at the level of 93%. Furthermore, moment-based features lead also to over 10% increase in CCR when the aim was to identify both bored and frustrated cases, within a 3-classs affect detection problem.

Summary: Accessibility in ICT and web-based applications has become an issue of great importance during the last years. However, the notion of accessibility was until recently undervalued in the web services domain. Trying to fill this gap, this paper presents work conducted towards enabling web services (WS) with accessibility characteristics, trying to ensure that HCI through applications utilizing them is accessible. For this purpose, a WS accessibility assessment framework has been deployed, having as basis guidelines which if followed, can ensure that accessible WSs are developed. In order to further facilitate the development of accessible WSs, a WS accessibility assessment tool has been developed on the basis of the proposed framework. In its current implementation, the tool is capable to automatically assess whether SOAP- or REST- based services conform to proposed guidelines. Thus, by using this tool, developers can be significantly facilitated towards developing accessible web services, or also enriching their already developed not-accessible ones with accessibility characteristics and so as to make them accessible.

Summary: In this paper we introduce a mechanism enabling applications to present information retrieved from different services, thus delivered with different structure, in a homogeneous and seamless fashion. This mechanism was an outcome of the research that took place within the European Integrated Project ASK-IT. The project developed an ambient intelligence framework which supports mobility impaired people on the move to access context-sensitive information dependant on user geographic location and the use case under consideration. The information derives from geographically dispersed web services and is rendered on mobile devices. The ASK-IT framework enables the presentation of information that covers a wide variety of domains which belong to the info-mobility scope (Points of Interest, Route Guidance etc.). Our approach deals with the integration of information-providing services, in order to facilitate the homogeneity of the final presentation of the content, through the end-user application.
