Humans communicate their affective states through different media, both verbal and non-verbal, often used at the same time. The knowledge of the emotional state plays a key role to provide personalized and context-related information and services. This is the main reason why several algorithms have been proposed in the last few years for the automatic emotion recognition. In this work we exploit the correlation between one's affective state and the simultaneous body expressions in terms of speech and gestures. Here we propose a system for real-time emotion recognition from gestures. In a first step, the system builds a trusted dataset of association pairs (motion data → emotion pattern), also based on textual information. Such dataset is the ground truth for a further step, where emotion patterns can be extracted from new unclassified gestures. Experimental results demonstrate a good recognition accuracy and real-time capabilities of the proposed system.

In this paper, we use research through design approach to introduce the skateboarding community to the maker's culture. Our goal was to provide an opportunity for skaters to experience sketching with technology, sharing ideas on making obstacles embedded with technology, executing one of the ideas and participating in envisioning co-created DIY (Do-It-Yourself) urban skateboarding spaces. In total, twenty-eight skateboarders were actively involved in the process of sketching, ideation, and subsequently making and evaluating a sound-based interactive skateboarding obstacle. The contributions of this paper include the framework for supporting maker activities for and with skateboarders, the artefact itself and the knowledge that emerged from its use in the appropriate urban environment. Finally, the highlights from interviews with twelve highly skilled skaters are provided. The analysis of the interviews resulted in the improvement of the initial framework that was based on the five key principles of creativity in everyday life. Furthermore, the skaters shared their reflections on the use of the obstacle, the making process, and speculated around the emergence of participatory maker culture within the community and possibilities to create urban environments that include creative DIY projects, such as the described one.

Designing a navigation aid adapted to older pedestrians' specificities could help in preserving their autonomy. Indeed, older people rely on walk for their daily journeys more than any other people. But cognitive and perceptive abilities may decline with aging and impair the pedestrian mobility. This study was aimed at comparing visual, auditory and haptic guidance messages among older pedestrians. Navigation performance and user experience (UX) were taken into account. Time to destination and rate of correct responses were measured in a pedestrian navigation simulator. Post-activity interviews were used to question participants' perceptions, feelings and hesitations. Results showed great performance and UX for visual messages, whereas results were mixed for haptic messages.

Bus stops are key touchpoints to improve the quality and engagement of citizens with public transports. Despite their ubiquity in modern urban landscapes they are seldom considered a key design/technology element in improving the public transport experience. This paper describes a design case study where different teams attempted to improve bus stops using interactive technologies. The resulting concept prototypes were designed to provide citizens and tourists with (i) safe, attractive and accessible public spaces, (ii) attractive, accessible and efficient public transport; and, (iii) smart traveller information tools and services for sustainable mobility. Our case was set in Madeira, a medium sized European island, where tourism widely contribute to the local economy and buses represent the only available public mean of transport. We present the research insights and the design concepts leading to improve engagement and use of public transport.

RAWGraphs is an open source web application for the creation of static data visualisations that are designed to be further modified. Originally conceived for graphic designers to provide a series of tasks not available with other tools, it evolved into a platform that provides simple ways to map data dimensions onto visual variables. It presents a chart-based approach to data visualisation: each visual model is an independent module exposing different visual variables that can be used to map data dimensions. Consequently, users can create complex data visualisations. Finally, the tool is meant to produce outputs that are open, that is, not subjected to proprietary solutions, which can be further edited.

Geo-localized, mobile applications can simplify a tourist visit, making the relevant Point of Interests more easily and promptly discernible to users. At the same time, such solutions must avoid creating unfitting or rigid user profiles that impoverish the users' options instead of refining them. Currently, user profiles in recommender systems rely on dimensions whose relevance to the user is more often presumed than empirically defined. To avoid this drawback, we build our recommendation system in a two-step process, where profile parameters are evaluated preliminarily and separately from the recommendations themselves. We describe this two-step evaluation process including an initial survey (N = 206), and a subsequent controlled study (N = 24). We conclude by emphasizing the benefit and generalizability of the approach

This paper proposes a novel conceptual architecture for smart homes as well as a new approach to home-inhabitant interaction. HOME is an intelligent agent based on a Belief-Desire-Intention (BDI) model, extended with the concept of values that represent abstract and permanent needs, such as health, comfort or security, which drive its decision making activity. Values, beliefs, desires and intentions are also the basic conceptual entities of inhabitant-system dialogue: the ultimate goal of HOME is to satisfy inhabitant needs and preferences, by taking into account knowledge about the environment and available devices, such as sensors and actuators. The result is a peer-to-peer interaction, where (the best) decisions emerge from a dialectic behavior.

Even though today's computers are used for many different types of tasks, they still rely on user interfaces designed for office workers in the 1980s. HCI researchers have produced a slew of innovative interaction styles, from gestural interaction to mixed reality and tangible interfaces, but they have not replaced traditional GUIs. I argue that we must devise fundamental principles of interaction that unify, rather than separate, interaction styles in order to support the diversity of uses and users. I describe ongoing work on my ERC advanced grant, ONE, which explores how the concepts of information substrates and interaction instruments create digital environments that users can appropriate and (re)combine at will.

Many human factor issues regarding automated driving systems are still unresolved. For instance, it is not fully clear if, and to what extent, drivers will accept and trust this novel technology. Trust in technology is of utmost importance to avoid both disuse and misuse. Possibilities for increasing user trust in automated driving systems include proper feedback aiming to build a shared mental model so that system intentions are visible to the driver. A potential approach could be to augment traffic and other relevant objects in the environment. Technical advancements in display technology would allow the use of windshield displays in the near future. To investigate the effect of augmented reality aids (presented as augmentations of traffic objects) in potentially ambiguous situations, we conducted a user study (n=26) and assessed qualitative (trust scale TS, technology acceptance model TAM) and quantitative (HRV) factors. Initial results indicate that augmenting sensor data in the driver's line of sight can lead to increased trust and acceptance.

Building a long-lasting personal relationship with visitors by maintaining their engagement after the visit is one of the most challenging endeavours cultural heritage sites face. When successful, this connection fosters new opportunities for the visitor to get in touch with the heritage, e.g. to visit again or to take part in cultural activities. One way to establish a personal connection is via personalisation services that generate souvenirs for the visitors to take away and foster future engagements with the heritage. This paper discusses how the techniques for personalised text generation can be applied to produce post-visit postcards exploiting the interaction logs collected during the museum visit. The personalised postcard summarises the visit, creates a link with what was experienced and suggests further paths for content discovery. A user study conducted over four weeks confirms the appreciation for the personalised postcard and suggests future developments.
