CLUE: A Usability Evaluation Checklist for Multimodal Video Game Field Studies with Children Who Are Blind
Multimodal video games can enhance the cognitive skills of children who are blind by allowing interaction with scenarios that would be unfeasible in their everyday life. To assist the identification of relevant interface and interaction issues when children who are blind are playing multimodal video games, we propose a Checklist for Usability Evaluation of Multimodal Games for Children who are Blind (CLUE). CLUE was designed to assist researchers and practitioners in usability evaluation field studies, addressing multiple aspects of gameplay and multimodality, including audio, graphics, and haptics. Overall, initial evidence indicates that the use of CLUE during user observation helps to raise a greater number of relevant usability issues than other methods, such as interview and questionnaire. CLUE makes the analysis of recorded user interactions a less time- and effort-consuming process by guiding the identification of interaction patterns and usability issues
Action video game play and transfer of navigation and spatial cognition skills in adolescents who are blind
For individuals who are blind, navigating independently in an unfamiliar environment represents a considerable challenge. Inspired by the rising popularity of video games, we have developed a novel approach to train navigation and spatial cognition skills in adolescents who are blind. Audio-based Environment Simulator (AbES) is a software application that allows for the virtual exploration of an existing building set in an action video game metaphor. Using this ludic-based approach to learning, we investigated the ability and efficacy of adolescents with early onset blindness to acquire spatial information gained from the exploration of a target virtual indoor environment. Following game play, participants were assessed on their ability to transfer and mentally manipulate acquired spatial information on a set of navigation tasks carried out in the real environment. Success in transfer of navigation skill performance was markedly high suggesting that interacting with AbES leads to the generation of an accurate spatial mental representation. Furthermore, there was a positive correlation between success in game play and navigation task performance. The role of virtual environments and gaming in the development of mental spatial representations is also discussed. We conclude that this game based learning approach can facilitate the transfer of spatial knowledge and further, can be used by individuals who are blind for the purposes of navigation in real-world environments
Computer Entertainment Technologies for the Visually Impaired: An Overview
Over the last years, works related to accessible technologies have increased both in number and in quality. This work presents a series of articles which explore different trends in the field of accessible video games for the blind or visually impaired. Reviewed articles are distributed in four categories covering the following subjects: (1) video game design and architecture, (2) video game adaptations, (3) accessible games as learning tools or treatments and (4) navigation and interaction in virtual environments. Current trends in accessible game design are also analysed, and data is presented regarding keyword use and thematic evolution over time. As a conclusion, a relative stagnation in the field of human-computer interaction for the blind is detected. However, as the video game industry is becoming increasingly interested in accessibility, new research opportunities are starting to appear
3D assistive technologies and advantageous themes for collaboration and blended learning of users with disabilities
The significance of newly emergent 3D virtual worlds to different genres of users is currently a controversial subject in deliberation. Users range from education pursuers, business contenders, and social seekers to technology enhancers and many more who comprise both users with normal abilities in
physical life and those with different disabilities. This study aims to derive and critically analyze, using grounded theory, advantageous and disadvantageous themes and their sub concepts of providing elearning through 3D Virtual Learning Environments (VLEs), like Second Life, to disabled users; hence
providing evidence that 3DVLEs not only support traditional physical learning, but also offer e-learning opportunities unavailable through 2D VLEs (like moodle, blackboard), and offer learning opportunities unavailable through traditional physical education. Furthermore, to achieve full potential from the above mentioned derived concepts, architectural and accessibility design requirements of 3D educational facilities proposed by different categories of disabled students to accommodate for their needs, are demonstrated
Virtual Reality Games for Motor Rehabilitation
This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion

Augmenting the field experience: a student-led comparison of techniques and technologies
In this study we report on our experiences of creating and running a student fieldtrip exercise which allowed students to compare a range of approaches to the design of technologies for augmenting landscape scenes. The main study site is around Keswick in the English Lake District, Cumbria, UK, an attractive upland environment popular with tourists and walkers. The aim of the exercise for the students was to assess the effectiveness of various forms of geographic information in augmenting real landscape scenes, as mediated through a range of techniques and technologies. These techniques were: computer-generated acetate overlays showing annotated wireframe views from certain key points; a custom-designed application running on a PDA; a mediascape running on the mScape software on a GPS-enabled mobile phone; Google Earth on a tablet PC; and a head-mounted in-field Virtual Reality system. Each group of students had all five techniques available to them, and were tasked with comparing them in the context of creating a visitor guide to the area centred on the field centre. Here we summarise their findings and reflect upon some of the broader research questions emerging from the project

Introduction to location-based mobile learning
[About the book]
The report follows on from a 2-day workshop funded by the STELLAR Network of Excellence as part of their 2009 Alpine Rendez-Vous workshop series and is edited by Elizabeth Brown with a foreword from Mike Sharples. Contributors have provided examples of innovative and exciting research projects and practical applications for mobile learning in a location-sensitive setting, including the sharing of good practice and the key findings that have resulted from this work. There is also a debate about whether location-based and contextual learning results in shallower learning strategies and a section detailing the future challenges for location-based learning
