Article
Purpose Because of social interaction difficulties, cognitive characteristics and sensory sensitivity, people with autism spectrum disorder (ASD) may struggle with independence and active participation in urban contexts. Through understanding how people with ASDs experience and perceive urban spaces, the Personalized Interactive Urban Maps for Auti...
Article
In this report, we summarise the program and takeaways from the 1 st edition of the Workshop on Information Retrieval for Understudied Users (IR4U2), co-located with the 46 th European Conference on Information Retrieval (ECIR). Date : 24 March 2024. Website : https://ir4u2workshop.wixsite.com/ir4u2.
Chapter
In the current digital landscape, humans take center stage. This has caused a paradigm shift in the realm of intelligent technologies, prompting researchers and (industry) practitioners to reflect on the challenges and complexities involved in understanding the (potential) users of the technologies they develop. In this chapter, we provide an overv...
Chapter
Information Retrieval (IR) remains an active, fast-paced area of research. However, most advances in IR have predominantly benefited the so-called “classical” users, e.g., English-speaking adults. We envision IR4U2as a forum to spotlight efforts that, while sparse, consider diverse, and often understudied, user groups when designing, developing, as...
Article
Mutual comprehension is a crucial component that makes a conversation succeed. While it can be easily reached through the cooperation of the parties in human-human dialogues, such cooperation is often lacking in humancomputer interaction due to technical problems, leading to broken conversations. Our goal is to work towards an effective detection o...

Tourists spend a lot of effort in planning itineraries when organizing a trip. This is a complex activity that involves selecting the places to visit and dealing with a number of temporal issues to generate a schedule for the visit. In the paper we propose an architecture for a recommender that suggests personalized tourist itineraries and a person...
Chapter
In this paper we propose an approach that combines genetic algorithms and temporal constraint satisfaction for generating personalized tourist itineraries. Not only does the personalization process take into account user preferences about the places to visit but also a number of temporal constraints (e.g., opening hours, time for visiting each plac...

Climate crisis has become one of the main challenges of the 21st century. However, there appears to be a lack of awareness among individuals regarding the impact of our daily routines on the environment. Virtual Reality has shown to be an effective technology to virtually bring people to emotional scenarios, such as, in this case, a dystopian futur...

Field trips enrich learning programs with out-of-school activities that can bring gains in students’ academic content knowledge and personal growth. However, they are a source of anxiety for teachers because of the bureaucracy, pedagogy, etc., risks they imply. To address this issue, we propose FieldTripOrganizer, a field trip planner based on the...

Autism is characterized by peculiar sensory processing. The sensory features of a place may have a crucial impact on the decision a person with autism makes when choosing what to visit in a tourist experience. We present a map-based mobile app, conceived for people with mid to high-functioning autism, which exploits sensory features of places to fi...

Nowadays, many people suffer from depression, anxiety disorder, stress and bad emotions. Most of the times, the causes are a chaotic lifestyle, stressful jobs and activities, wrong habits and a permanent sense of uncertainty. Therefore, well-being plays an increasingly important role in people’s lives, as it can help them to prevent chronic disease...
Article
Full-text available
Negative information plays an important role in the way we express our preferences and desires. However, it has not received the same attention as positive feedback in recommender systems. Here we show how negative user preferences can be exploited to generate recommendations. We rely on a logical semantics for the recommendation process introduced...

When suggesting Points of Interest (PoIs) to people with autism spectrum disorders, we must take into account that they have idiosyncratic sensory aversions to noise, brightness and other features that influence the way they perceive places. Therefore, recommender systems must deal with these aspects. However, the retrieval of sensory data about Po...

Article
The suggestion of Points of Interest (PoIs) to people with autism spectrum disorders challenges the research about recommender systems by introducing an explicit need to consider both user preferences and aversions in item evaluation. The reason is that autistic users' perception of places is influenced by sensory aversions, which can cause stress...

Nowadays, most interactive social systems allow users to react to their contents and exploit user reactions to provide intelligent behaviours, such as adaptation or recommendation. Therefore, carefully understanding and designing the user/system dialogue that revolves around reaction provisioning is a crucial aspect. In this paper, we introduce the...
Chapter
One of the common traits of individuals with Autism Spectrum Disorder (ASD) is the inclination to perceive unknown situations and environments as a source of stress and anxiety. It is common for them to tend to avoid novel experiences -including traveling to new places- and therefore an environments like an airport can be overwhelming. Virtual Real...

In this paper we study whether visualizations based on color maps can encourage the intuitive interpretation of detailed descriptions, as the ones proposed in the formal model UPRISE, designed to ana- lyze interactive system components, such as reaction tools, which allow users to provide reactions. We carried out a between-subjects experiment wher...
Article
The aim of this paper is to provide logical foundations for knowledge-based recommender systems, for which, unlike other problem solving tasks, a comprehensive formalization is not yet available. This goal is justified by the need to compare recommenders based on the way they use knowledge to generate recommendations and, consequently, on the under...

Article
People with autism have idiosyncratic sensory experiences, which may impact on how they live the “spaces” of their everyday life. Starting from an investigation of their conception and experience of “secure places,” we defined a series of user requirements for designing technology that supports their everyday movements in the urban environment. On...
Preprint
The suggestion of Points of Interest to people with Autism Spectrum Disorder (ASD) challenges recommender systems research because these users' perception of places is influenced by idiosyncratic sensory aversions which can mine their experience by causing stress and anxiety. Therefore, managing individual preferences is not enough to provide these...
