Co-participatory multimodal intergenerational storytelling : preschool children’s relationship with modality creating elder inclusion

2021

The COVID-19 crisis has highlighted elderly people as a vulnerable and excluded community, and connecting to the younger social media generation requires a shift in intergenerational storytelling performance. Recent research on multimodality has emphasized its benefits for the interactional process in storytelling. This study examines three aspects of storytelling – participation, multimodality, and emotional interaction – and uses co-creation and multimodal discourse analysis to investigate two questions: (1) To what extent can intergenerational storytelling benefit older people’s community engagement? (2) In a globalized world, how do children’s relationships with modalities create new l…

Why braille reading is important and how to study it /Por qué es importante la lectura en braille y cómo estudiarla

2016

AbstractDespite its relevance in theoretical and practical terms, braille reading has received little attention from researchers. Awareness of the pros and cons of the different procedures used to examine braille reading is needed to facilitate the realization of systematic studies and to improve teaching methods in braille reading. This study provides a critical examination of braille reading methods and highlights key points for future studies on tactile reading.

Studying social media as semiotic technology: a social semiotic multimodal framework

2018

How do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) m…

Public Institutions as Learning Environments in Finland

2012

Public cultural institutions in this article are understood to be a part of the built up environment. The services provided by these are available to all citizens in Finland. These include: libraries, museums, various art institutions, theatres, music institutions and science centres. The expertise of the writers of the article is based on museums and libraries as learning environments, so the content of the article will focus on them. Finland has a broad network of public libraries and museums.

Effect of Motion Artifact on Digital Camera Based Heart Rate Measurement

2017

International audience; Depression is one of the most prevalent mental disorders, burdening many people world-wide. A system with the potential of serving as a decision support system is proposed, based on novel features extracted from facial expression geometry and speech, by interpreting non-verbal manifestations of depression. The proposed system has been tested both in gender independent and gender based modes, and with different fusion methods. The algorithms were evaluated for several combinations of parameters and classification schemes, on the dataset provided by the Audio/Visual Emotion Challenge of 2013 and 2014. The proposed framework achieved a precision of 94.8% for detecting p…

GESTURES AS A COMMUNICATION FEATURE IN CHILDREN WITH DEVELOPMENTAL LANGUAGE DISORDER

2019

Gestures as non-verbal communication allow us to express our attitude, emotional state, and it functions unconsciously. The verbal communication appears in the life of a child about 2 years of age and gradually replaces the non-verbal communication. However, children with DLD (Developmental Language Disorder) at the age of 3 and more do not speak or speak using separate sounds and combinations of sounds in their speech and use gestures broadly; it helps them to communicate with others. The aim of the article is to explore what kind of gestures as non-verbal communication are used by children with DLD in order to communicate with peers and adults. Based on the scientific literature of the re…

On Human–Computer Interaction in Brain–Computer Interfaces

2014

In this chapter, theoretical reflections on human–computer interaction in brain–computer interfaces (BCIs) are combined with the results of an empirical investigation concerning non-invasive EEG-based BCI users’ experiences with this technology. After a short overview of transhumanist visions in the field of neurotechnology this text discusses some anthropological positions concerning interaction between man and technical devices. The focus will be on the concept of “transparency”. Then some empirical results of a pilot study which investigated BCI users’ experiences concerning human–computer interaction in BCI use are presented and discussed against the anthropological background.

Improving user experience via motion sensors in an Ambient Intelligence scenario

2013

Ambient Intelligence (AmI) is a new paradigm in Artificial Intelligence that aims at exploiting the information about the environment state in order to adapt it to the user preferences. AmI systems are usually based on several cheap and unobtrusive sensing devices that allow for continuous monitoring in different scenarios. In this work we present a gesture recognition module for the management of an office environment using a motion sensor device, namely Microsoft Kinect, as the primary interface between the user and the AmI system. The proposed gesture recognition method is based on both RGB and depth information for detecting the hand of the user and a fuzzy rule for determining the stat…
