Online Video Game Therapy for Mental Health Concerns: A Review

Background: There has been research on the use of offline video games for therapeutic purposes but online video game therapy is still fairly under-researched. Online therapeutic interventions have only recently included a gaming component. Hence, this review represents a timely first step toward taking advantage of these recent technological and cultural innovations, particularly for the treatment of special-needs groups such as the young, the elderly and people with various conditions such as ADHD, anxiety and autism spectrum disorders. Material: A review integrating research findings on two technological advances was conducted: the home computer boom of the 1980s, which triggered a flood of research on therapeutic video games for the treatment of various mental health conditions; and the rise of the internet in the 1990s, which caused computers to be seen as conduits for therapeutic interaction rather than replacements for the therapist. Discussion: We discuss how video games and the internet can now be combined in therapeutic interventions, as attested by a consideration of pioneering studies. Conclusion: Future research into online video game therapy for mental health concerns might focus on two broad types of game: simple society games, which are accessible and enjoyable to players of all ages, and online worlds, which offer a unique opportunity for narrative content and immersive remote interaction with therapists and fellow patients. Both genres might be used for assessment and training purposes, and provide an unlimited platform for social interaction. The mental health community can benefit from more collaborative efforts between therapists and engineers, making such innovations a reality.

On assigning place names to geography related web pages

In this paper, we attempt to give spatial semantics to Web pages by assigning them place names. The entire assignment task is divided into three sub-problems, namely place name extraction, place name disambiguation and place name assignment. We propose our approaches to address these subproblems. In particular, we have modified GATE, a well known named entity extraction software, to perform place name extraction using a US Census gazetteer. A rule-based place name disambiguation method and a place name assignment method capable of assigning place names to Web page segments have also been proposed. We have evaluated our proposed disambiguation and assignment methods on a Web page collection referenced by the DLESE metadata collection. The results returned by our methods are compared with manually disambiguated place names and place name assignment. It is shown that our proposed place name disambiguation method works well for geo/geo ambiguities. The preliminary results of our place name assignment method indicate promising results given the existence of geo/non-geo ambiguities among place names

A checklist for evaluating open source digital library software

Purpose – Many open source software packages are available for organizations and individuals to create digital libraries (DLs). However, a simple to use instrument to evaluate these DL software packages does not exist. The objectives of the present work are to develop a checklist for DL evaluation and use this checklist on four DL software packages.Design/methodology/approach – Features that characterized “good” open source DL software were determined from the literature. First identified were essential categories of features that DL software should possess. These categories were then decomposed into supporting features. From these, a checklist that covered all such features was developed. The checklist was then used to evaluate four popular open source DL software packages (CDSware, EPrints, Fedora, and Greenstone) for the purposes of assessing suitability for use in a DL project to be undertaken by the authors.Findings – A checklist consisting of 12 categories of items was developed. Using this, Greenst...

Strategies for designing effective psychotherapeutic gaming interventions for children and adolescents

A range of face-to-face therapies and interventions for children and adolescents with mental health problems have been developed over the years and include cognitive-behavioral therapy, play therapy and applied behavior analysis. The popularity of computer games has grown exponentially in the last decade and has been widely accepted by children, adolescents and adults alike. Mental health professionals have therefore been exploring the use of these games to complement traditional treatment methods. To date however, there has been little known concrete evidence of the effectiveness of computer games for the treatment of children and adolescents with mental health conditions. Key to the success of such games is that at the outset, they must be well-designed. This paper reviews extant relevant computer gaming literature to propose a set of guidelines and strategies for the design of psychotherapeutic games targeted at children and adolescents. The issues raised concern both the game player as well as the game itself. As part of this review, limitations of existing work and areas of future research are also discussed.

G-Portal: a map-based digital library for distributed geospatial and georeferenced resources

As the World Wide Web evolves into an immense information network, it is tempting to build new digital library services and expand existing digital library services to make use of web content. In this paper, we present the design and implementation of G-Portal, a web portal that aims to provide digital library services over geospatial and georeferenced content found on the World Wide Web. G-Portal adopts a map-based user interface to visualize and manipulate the distributed geospatial and georeferenced content. Annotation capabilities are supported, allowing users to contribute geospatial and georeferenced objects as well as their associated metadata. The other features included in G-Portals design are query support, content classification, and content maintenance. This paper will mainly focus on the architecture design, visualization and annotation capabilities of G-Portal.

A predictive framework for retrieving the best answer

In a question answering (QA) system, each user interaction with the system is different and since there are a variety of arguably correct answers to complex questions, identifying factors for improving the quality of the retrieved answer is difficult. This research aims to develop a framework that identifies predictive variables for the best quality answer in a QA system. It was found that accuracy, completeness and relevance were predictors of best answer. We believe that these findings can serve to guide future developments in the answer extraction modules in the QA systems.

Web 2.0 applications in government web sites: Prevalence, use and correlations with perceived web site quality

Purpose – The purpose of this paper is to investigate the extent to which Web 2.0 applications are prevalent in government web sites, the ways in which Web 2.0 applications have been used in government web sites, as well as whether the presence of Web 2.0 applications correlates with the perceived quality of government web sites.Design/methodology/approach – Divided equally between developing and advanced economies, a total of 200 government web sites were analysed using content analysis and multiple regression analysis.Findings – The prevalence of seven Web 2.0 applications in descending order was: RSS, multimedia sharing services, blogs, forums, social tagging services, social networking services and wikis. More web sites in advanced countries include Web 2.0 applications than those in developing countries. The presence of Web 2.0 applications was found to have a correlation with the overall web site quality, and in particular, service quality.Research limitations/implications – This paper only covers g...

Why We Share: A Study of Motivations for Mobile Media Sharing

Mobile phones equipped with cameras have become popular among consumers, and this has fuelled an increase in mobile media sharing. The present research investigates the sharing of mobile media by conducting a diary study to specifically understand the type of media captured and shared, and the motivations behind these activities. Participants maintained a month-long diary, documenting their media sharing activities. Post-study interviews were also conducted to elicit additional information not captured in the diary. Results suggest a range of motivational factors, and that social and emotional influences played an important role in media sharing behavior. Participants were also more inclined to share photos that any other media due to cost and transmission time considerations. Implications of our work are also discussed.

Mobile G-Portal supporting collaborative sharing and learning in geography fieldwork: an empirical study

Integrated with G-Portal, a Web-based geospatial digital library of geography resources, this paper describes the implementation of Mobile G-Portal, a group of mobile devices as learning assistant tools supporting collaborative sharing and learning for geography fieldwork. Based on a modified Technology Acceptance Model and a Task-Technology Fit model, an initial study with Mobile G-Portal was conducted involving 39 students in a local secondary school. The findings suggested positive indication of acceptance of Mobile G-Portal for geography fieldwork. The paper concludes with a discussion on technological challenges, recommendations for refinement of Mobile G-Portal, and design implications in general for digital libraries and personal digital assistants supporting mobile learning.

Perceptions, quality and motivational needs in image tagging human computation games

Human computation games (HCGs) are applications that use games to harness human intelligence to perform various computational tasks. That is, users perform computations as a byproduct of being entertained while playing a game. Such games are increasing in popularity and it is critical to examine how different types of HCG affect players’ perceptions and performance. In addition, understanding their motivational appeal to different players is also important to good HCG design. In the present research, we focus on image tagging HCGs, where users play games to generate keywords for images. Three versions were created: a collaborative HCG which required players to cooperate, a competitive HCG where players worked against each other, and a control non-game manual tagging application. The applications were evaluated to uncover the quality of the tags, users’ perceptions of these variants, and the influence of motivational needs on usage intention. Results suggest that, while participants reported liking the collaborative and competitive HCGs over the control application, those using the latter seemed to generate better quality tags. Further, using the trichotomy of needs theory, we found that an individual’s need for achievement and power influenced intention to use the various applications.
