To help ensure that users ’ interactions with a system are successful, preparation of content and its presentation to users must take into account (a) what information needs to be extracted, (b) the way in which this information should be stored and organized, (c) the methods for retrieving the infor-mation, and (d) how the information should be displayed. The goal of this article is to discuss the generic problems facing content preparation and evaluate the current methods available to help remedy them, as well as identify areas in which more re-search is needed. The material presented in this article was a result of the collective ef-forts of the participants of a special “white paper ” session that was part of the 9th Inter-national Conference on Human–Computer Interaction (HCI International 2001).

The detection of quality deviations currently depends on the individual competence of the persons involved in the production process. With the automatic recognition of textured surfaces in camera images, valuable information can be given to support these persons in their decisions. For the design of augmented reality systems, the cognitive decision-making processes are first described in a model-based way and the requirements for design of the decision-making process are defined. The different lighting environments in the industrial process represent one of the important requirements of the augmented reality system, to function independently of the lighting. The good perceptibility of the information is the basic requirement for the recognition of contents. When implementing an augmented reality system, i...

Looking at users, service providers aim to offer users a great holistic experience across the entire journey. For designing the holistic mobility experience, methods and tools must be provided that address the emerging challenges. This article examines the method experience map to apply it to the field of mobility. The goal is to create assistance for the design activities: Understanding existing experience, exploring service ideas and communicating service concepts. Based on a best practice analysis, the article investigates the structure of currently used experience maps. Building on these results, a two-stage expert study is conducted in order to provide a framework for the creation and analysis of a mobility experience map. Finally, the article discusses the implications for the analysis of the holistic experience using the mobility experience map.

Today, mobility planning represents a major challenge for cities, especially when it comes to developing innovative and sustainable services and measures. The topic of mobility is enjoying great popularity in research. Numerous projects and initiatives are attempting to support cities in taking a step towards sustainable urban mobility. But it is important to understand the problems and challenges that mobility planners are faced with when shaping sustainable mobility. Only in this way future support activities can be tailored even more to the requirements and specific needs of mobility planners. The paper presents 15 challenges that cities and mobility planners face when developing mobility solutions. The challenges were identified in working together with different cities in the frame of the CIVITAS SUITS (CIVITAS SUITS is a R&D project funded by the European Union in the frame of the Horizon2020 program. The aim of the project ...

Virtual Reality (VR) is a technology that can facilitate the early evaluation process by showing later life situations of a product as early as at the design stage. However, the application of VR in the industry is currently limited due to high model preparation effort and poor reusability of already prepared models. Therefore, this thesis pursues towards the development of a method that can facilitate the early evaluations of the product in VR and thus, facilitate the use of VR in the product development process. This method aims at achieving generic behavioural descriptions for use in VR that can be reused as well to form dynamic use cases of a product in different VR-systems. The focus lies on reducing the overall preparation effort of VR-mo...

The SensoMot-project (“Sensor Measures of Motivation for Adaptive Learning”) aims at identifying critical motivational incidents during adaptive e-learning sessions in the context of university courses of micro- and nano-technology through sensory acquisition with current consumer wearables. These critical motivational incidents will be used to adapt learning content at runtime and thus enhance motivation.

A user task-based approach to interaction design guidance for iTV applications is suggested to easily integrate with a user-centred application development process. Based on the analysis of existing applications, several generic, iTV-specific user tasks are presented. For these user tasks, proven interaction design solutions were empirically identified by usability testing eight broadcasted applications. Specific design solutions to support the user tasks accessing content item and viewing content item are described. Usability test results and design guidance on the design of menus, video multi-screens, indexes, content presentation areas, paging, and scrolling are presented. Target audiences of this chapter are the iTV user interface designers and usability researchers.

However, an essential challenge that all smart home ideas face is the provision of the ground truth i.e. the labeled training data required to train the machine learning algorithms which achieve the smartness of the smart home. Another challenging task is to evaluate the correctness of the collected ground truth so that we can be sure that we train the system with correct data which represents the reality. In order to build a smart home which is interactive and adaptable to the behavior and preferences of its inhabitants, we need to have comprehensive information about the everyday behavior and preferences of the inhabitants of the smart home. This comprehensive information which needs to be collected represents the ground truth in the context of our smart home research. Many technologies have been utilized in order to collect this information. In this paper, we present our approach for collecting the ground truth in smart homes in a nonintrusive way. More importantly, we present our methodology for evaluating the correctness of the collected ground truth.

Developing systems, e.g. mobile applications, which are used at varying locations, requires knowledge of the environmental context as well. This paper describes an approach for the analysis of varying environmental contexts in public transport. The results are presented as context templates to derive information needs of users in public transport dependent on influencing context factors and can serve as a communication tool for interdisciplinary groups.
