SOS TUTORIA UC: A Diversity-Aware Application for Tutor Recommendation Based on Competence and Personality

SOS TUTORIA UC is a student connection application aimed at facilitating academic assistance between students through external tutoring outside of the application. To achieve this, a responsive web application was designed and implemented, integrated with the WeNet platform, which provides various services for user management and user recommendation algorithms. This study presents the development and validation of the experience in the application by evaluating the importance of incorporating the dimension of personality traits, according to the Big Five model, in the process of recommending students for academic tutoring. The goal is to provide support for students to find others with greater knowledge and with a personality that is \'different\', \'similar\' or \'indifferent\' to their own preferences for receiving academic assistance on a specific topic. The integration with the WeNet platform was successful in terms of components, and the results of the recommendation system testing were positive but have room for improvement.Comment: 5 page

Illusions, auditory

Definition: Auditory illusions occurs when the listener hears sounds that are not present in the stimulus and our brain organizes and interprets sensory stimulation producing a distortion of a sensory perception. It is possible to distinguish between classical examples of auditory illusions and the illusions that emerge because of the interplay of audition with multisensory perception. Auditory illusions can be then taken into account in designing Enactive Interfaces for their possible creative uses. A good parallel can be drawn with visual illusions, often used by hyper realistic painting (e.g. the image of a mirror without the painter that is painting it, etc.). Auditory illusions in an immersive, enactive environment can be made to be much more striking than in a usual one because an immersive environment allows to enhance the cooperation between modalities. The interaction between hearing, vision and haptics can be tightly controlled in such an environment and the cooperation between these modalities can therefore be increased or decreased at will

The voice painter

Very often when looking at a painting or touching a sculpture it is possible to experience the meaning of being a perceiver as enactor of perceptual content. The piece of art that we try to explore forces us to move around the object in order to discover new meanings and sensations. We need to interact with the artistic object in order to completely understand it. Is it possible to think about sound and music in this way? Is the auditory and musical experience prone to such investigation? This paper tries to describe an enactive system that, by merging the concepts of autographic and allographic arts, transforms the spectator of a multimodal performance into the performer--perceiver--enactor. The voice painter, an instrument to paint with our voice movement in a closed loop interaction, offers a new artistic metaphor as well as a potentially useful tool for speech therapy programs

Voice Painter: un'interfaccia multimodale per dipingere con la voce

Il presente lavoro descrive un sistema - denominato voice painter - che permette di dipingere su una tela virtuale attraverso l'uso della propria voce e del movimento del corpo. Tale sistema, trasforma lo spettatore della performance multimodale in un performer/en-attore, proponendo cos\uec una nuova metafora artistica

Integrating auditory feedback in motor rehabilitation systems.

The goal of this paper is to address a topic that is rarely investigated in the literature of technology-assisted motor rehabilitation, i.e., the integration of auditory feedback in the rehabilitation device. We first review current trends and open issues in technology-assisted rehabilitation. Up-to-date uses of auditory feedback in such context are then reviewed. In particular, a comparative quantitative analysis over a large corpus of recent literature suggests that the potential of auditory feedback in rehabilitation systems is currently largely underestimated. Finally, several scenarios in which the use of auditory feedback can contribute to overcome some of the main current limitations of rehabilitation systems, in terms of user engagement, improved motor learning, acute phase rehabilitation, standardization of the rehabilitation process and development of home rehabilitation devices, are proposed

Learning sounding gestures

Non-visual senses can be used in toys to enhance and enrich the play experience. Previous research has shown that -- especially for young children developing sensory-motor skills -- exploration and play are two tightly linked activities: everything is new and needs to be ``studied'', and playful behaviors emerge from active exploration. The main idea of this paper is to provide a new approach in designing and realizing objects that elicit this type of behavior and encourage exploration by providing dynamic, real-time haptic, tactile, auditory feedback depending on a child's gestures, movements, and emitted sounds. These toys provide interaction based on the enactive paradigm, where multimodal feedback is intimately tied to action -- i.e. the human is ``in the loop''. Moreover, these musical toys will teach how to perform musical gestures

HOBA-VR: HRTF On Demand for Binaural Audio in Immersive Virtual Reality Environments

One of the main challenges of spatial audio rendering in headphones is the personalization of the so-called head-related transfer functions (HRTFs). HRTFs capture the listener's acoustic effects supporting immersive and realistic virtual reality (VR) contexts. This e-brief presents the HOBA-VR framework that provides a full-body VR experience with personalized HRTFs that were individually selected on demand based on anthropometric data (pinnae shapes). The proposed WAVH transfer format allows a flexible management of this customization process. A screening test aiming to evaluate user localization performance with selected HRTFs for a non-visible spatialized audio source is also provided. Accordingly, is might be possible to create a user profile that contains also individual non-acoustic factors such as localizability, satisfaction, and confidence
