Blind and visually impaired visitors’ experiences in museums: Increasing accessibility through assistive technologies

Authors
Vaz, R; Freitas, D; Coelho, A;

Publication
International Journal of the Inclusive Museum

Abstract
People with visual impairments generally experience many barriers when visiting museum exhibitions, given the ocular centricity of these institutions. The situation is worsened by a frequent lack of physical, intellectual and sensory access to exhibits or replicas, increased by the inaccessibility to use ICT-based local or general alternative or augmentative communication resources that can allow different interactions to sighted visitors. Few studies analyze applications of assistive technologies for multisensory exhibit design and relate them with visitors’ experiences. This article aims to contribute to the field of accessibility in museums by providing an overview of the experiences and expectations of blind and visually impaired patrons when visiting those places, based on a literature review. It also surveys assistive technologies used to enhance the experiences of visitors with vision loss while visiting museum exhibitions and spaces. From this, it is highlighted that adopting hybrid technological approaches, following universal design principles and collaborating with blind and visually impaired people, can contribute to integrate access across the continuum of visits. © Common Ground Research Networks, Roberto Vaz, Diamantino Freitas, António Coelho, Some Rights Reserved,

Abstract
Online masters’ program chairs need up-to-date information to monitor efficiently and effectively all the courses in the program for which they are responsible. Learning Management Systems supporting the operation of the online programme collect vast amounts of data about the learning process. These systems are geared to support individual teachers and students, not program chairs. This article presents the process that led to the development of a Dashboards for program chairs, based upon an analysis of their regular supervision tasks, decision-making information needs, and available data in the learning management system, Moodle. The information presented via the dashboard is aggregated and contextualised for all students enrolled in the program, in all its courses, contributing to improve decision-making in program chairing. The dashboard prototype is presented as a concrete outcome of this process, which can be replicated to achieve more advanced and updated versions, hopefully contributing to better program chairing. © 2021, Springer Nature Switzerland AG.

A Novel Tool for Immersive Authoring of Experiential Learning in Virtual Reality

Publication

Abstract
Training in VR can reduce risks and costs while allowing frequent and diversified experiential learning activities. We present a novel VR immersive authoring tool for experiential learning courses with industrial machinery. A trainer can create a course from scratch, defining all its components (structure, models, tools, and settings). The actions which trainees should perform can be specified by demonstration. After completing the course, trainees' actions will be matched against the trainer's.

The Relationship Between Cybersickness, Sense of Presence, and the Users' Expectancy and Perceived Similarity Between Virtual and Real Places

Abstract
This paper aims to explore the impact of sense of presence and cybersickness on the users' expectancy and perceived similarity between virtual and the corresponding real environments. Two virtual reality setups were tested (non-immersive and immersive) to achieve further conclusions. This research encompassed a quantitative analysis using data collection based on questionnaires, applied to a sample of 45 participants. A virtual experience was conducted (to explore users' cybersickness and sense of presence), followed by a visit to the actual real sites (to determine the degree of perceived similarity between the virtual and the corresponding real environment and if their expectations were fulfilled). Our results show a positive correlation between the global sense of presence and perceived similarity and users' expectancy for the non-immersive VR setup. A positive correlation was also found between the global cybersickness on both perceived similarity and users' expectancy for the immersive VR setup. Implications of such results for virtual tourism are discussed.

Abstract
The use of VR in industrial training contributes to reduce costs and risks, supporting more frequent and diversified use of experiential learning activities, an approach with proven results. In this work, we present an innovative immersive authoring tool for experiential learning in VR-based training. It enables a trainer to structure an entire VR training course in an immersive environment, defining its sub-components, models, tools, and settings, as well as specifying by demonstration the actions to be performed by trainees. The trainees performing the immersive training course have their actions recorded and matched to the ones specified by the trainer.
