Human factors in entertainment computing: designing for diversity

Although several casual gaming systems have been developed during the past years, little research examining the impact of human factors on the design and use of digital games has been carried out, and commercially available games are only partially suitable for audiences with special needs. The research project described within this paper aims to analyze and explore design guidelines for diverse audiences and results of focus group gaming sessions to develop a research toolbox allowing for the easy creation of adaptable and accessible game scenarios. Thereby, a controllable environment for the detailed evaluation of the interrelations between human factors and entertainment systems is provided. Results obtained by further testing will be integrated in the toolbox, and may foster the development of accessible games, thus opening up new opportunities for diverse audiences and allowing them to further engage in digital games.

Exergame design for elderly users: the case study of SilverBalance

In this paper, we discuss chances and challenges of game design for an elderly audience with a focus on the development of safe and usable exertion games for frail senior citizens. Based on an analysis of theoretical constraints, we conducted a case study which implements different balance tasks for elderly players featuring the Nintendo Wii Balance Board which encourages users to actively engage in game play. Furthermore, we tested the feasibility of the board as input device for our case study SilverBalance. Our results indicate that age-related impairments influence the use of video games among frail elderly in many respects, hence their needs have to be considered during the design process. In this context, our paper provides a foundation for future research regarding digital games for the elderly. © 2010 ACM

Combining brain-computer interfaces and assistive technologies: state-of-the-art and challenges

In recent years, new research has brought the field of EEG-based Brain-Computer Interfacing (BCI) out of its infancy and into a phase of relative maturity through many demonstrated prototypes such as brain-controlled wheelchairs, keyboards, and computer games. With this proof-of-concept phase in the past, the time is now ripe to focus on the development of practical BCI technologies that can be brought out of the lab and into real-world applications. In particular, we focus on the prospect of improving the lives of countless disabled individuals through a combination of BCI technology with existing assistive technologies (AT). In pursuit of more practical BCIs for use outside of the lab, in this paper, we identify four application areas where disabled individuals could greatly benefit from advancements in BCI technology, namely,“Communication and Control”, “Motor Substitution”, “Entertainment”, and “Motor Recovery”. We review the current state of the art and possible future developments, while discussing the main research issues in these four areas. In particular, we expect the most progress in the development of technologies such as hybrid BCI architectures, user-machine adaptation algorithms, the exploitation of users’ mental states for BCI reliability and confidence measures, the incorporation of principles in human-computer interaction (HCI) to improve BCI usability, and the development of novel BCI technology including better EEG devices

Glitchspace:teaching programming through puzzles in cyberspace

There is an increasing need to address the player experience in games-based learning. Whilst games offer enormous potential as learning experiences, the balance between entertainment and education must be carefully designed and delivered. Successful commercial games tend to focus gameplay above any educational aspects. In contrast, games designed for educational purposes have a habit of sacrificing entertainment for educational value which can result in a decline in player engagement. For both, the player experience is critical as it can have a profound effect on both the commercial success of the game and in delivering the educational engagement. As part of an Interface-funded research project Abertay University worked with the independent games company, Space Budgie, to enhance the user experience of their educational game Glitchspace. The game aimed to teach basic coding principles and terminology in an entertaining way. The game sets the player inside a Mondrian-inspired cyberspace world where to progress the player needs to reprogramme the world around them to solve puzzles. The main objective of the academic-industry collaborative project was to analyse the user experience (UX) of the game to increase its educational value for a standalone educational version. The UX design focused on both pragmatic and hedonic qualities such playability, usability and the psychological impact of the game. The empirical study of the UX design allowed all parties to develop a deeper understanding of how the game was being played and the initial reactions to the game by the player. The core research question that the study sought to answer was whether when designing an educational game, UX design could improve philosophical concepts like motivation and engagement to foster better learning experiences.</p

Tactor devices : using tactile interface designs for mobile digital appliances : a practice-based research thesis for the fulfilment of a Master of Design degree, College of Design, Fine Arts, and Music, Massey University, Wellington

This Thesis focuses the potential of communication interfaces that use tactors (tactile actuators) to improve user interactions with mobile digital devices which are currently based on audio and visual technologies. It presents two product concepts, which use tactile signals to enable new ways in tele-operations, such as tactile telecommunication and tactile navigation. Tactor interfaces, although still in its infancy as elements of modern digital communication and technology, have considerable potential for the future as designers attempt to maximise the use of all human senses in people's interaction with technology. Only the military and a few entertainment companies have introduced tactile signals into Human-Computer Interactions (HCI). Human touch perception uses the hands as the main sensing organs. They perceive tactile signals while handling, typing or navigating with digital devices and receive direct confirmation of physical actions. In contrast to other senses, touch perceptions are based on interactions with the sensed objects. The study analyses, experiments and evaluates if these interactions are useful in interface designs and recommends how tactile stimulations can be introduced to interface designs besides images and sounds that dominate the control of current digital appliances. Tactile actuators and sensors enable devices to use tactile signals, such as impulses and vibrations, to communicate with the users. Users and tactor devices will be able to communicate in a physical and direct way. Touch reflective interfaces, could react like living creatures that respond to touch, for example a cat that starts purring when touched. Digital product design is always challenged to create human-computer interactions that meet people's needs. Designing digital devices is difficult because they are not necessarily three-dimensional objects. They are stimulator of the human senses and can be as small as the sensing nerve endings that detect sensations. By miniaturisation, form and function become invisible and Product Design is increasingly incorporating Process Design that explores and enables new interactions between users and products to work interactively and efficiently. The study is divided into four chapters: Chapter 1 gives an introduction to the thesis. Chapter 2 presents a survey on current literature which examines the five human senses to define the limits and possibilities in interface design. It reviews current research on materials and technologies as well as the psychology and physiology of touch as a potential sense in human-computer interactions. It evaluates the technical feasibilty of tactile signal performances and how they could be used as tele-touch codes in navigation and telecommunication. Chapter 3 is focused on primary research undertaken to extend the knowledge in tactile sensing. It includes experiments, questionnaires, and concepts that give examples how tactor interfaces can be used in tele-operations. This section focuses on specific user groups, that may primarily benefit from tactile signal transmissions, such as sight and hearing-impaired people or professionals who have to deal with limited perceptions like fire fighters, for example. These case studies are aimed at exploring and expanding a wider range of possibilities in tactile device innovations in the networked society. Chapter 4 gives a conclusion of the research

Serious interface design for dental health: Wiimote-based tangible interaction for school children

This paper describes a camera-based approach towards creating a tangible interface for serious games. We introduce our game for dental health targeted at school children which implements the Nintendo WiiMote as infrared camera. Paired with a gesture-recognition system, this combination allows us to apply real-world items as input devices. Thereby, the game tries to address different aspects of dental hygiene along with the improvement of children's motor skills. In our focus group test, we found that tangible interfaces offer great potential for educational purposes and can be used to engage kids in a playful learning process by addressing their childlike curiosity and fostering implicit learning

Custom-designed motion-based games for older adults: a review of literature in human-computer interaction

Many older adults, particularly persons living in senior residences and care homes, lead sedentary lifestyles, which reduces their life expectancy. Motion-based video games encourage physical activity and might be an opportunity for these adults to remain active and engaged; however, research efforts in the field have frequently focused on younger audiences and little is known about the requirements and benefits of motion-based games for elderly players. In this paper, we present an overview of motion-based video games and other interactive technologies for older adults. First, we summarize existing approaches towards the definition of motion-based video games – often referred to as exergames – and suggest a categorization of motion-based applications into active video games, exergames, and augmented sports. Second, we use this scheme to classify case studies addressing design efforts particularly directed towards older adults. Third, we analyze these case studies with a focus on potential target audiences, benefits, challenges in their deployment, and future design opportunities to investigate whether motion-based video games can be applied to encourage physical activity among older adults. In this context, special attention is paid to evaluation routines and their implications regarding the deployment of such games in the daily lives of older adults. The results show that many case studies examine isolated aspects of motion-based game design for older adults, and despite the broad range of issues in motion-based interaction for older adults covered by the sum of all research projects, there appears to be a disconnect between laboratory-based research and the deployment of motion-based video games in the daily lives of senior citizens. Our literature review suggests that despite research results suggesting various benefits of motion-based play for older adults, most work in the field of game design for senior citizens has focused on the implementation of accessible user interfaces, and that little is known about the long-term deployment of video games for this audience, which is a crucial step if these games are to be implemented in activity programs of senior residences, care homes, or in therapy

Heuristic usability evaluation on games: a modular approach

Heuristic evaluation is the preferred method to assess usability in games when experts conduct this evaluation. Many heuristics guidelines have been proposed attending to specificities of games but they only focus on specific subsets of games or platforms. In fact, to date the most used guideline to evaluate games usability is still Nielsen’s proposal, which is focused on generic software. As a result, most evaluations do not cover important aspects in games such as mobility, multiplayer interactions, enjoyability and playability, etc. To promote the usage of new heuristics adapted to different game and platform aspects we propose a modular approach based on the classification of existing game heuristics using metadata and a tool, MUSE (Meta-heUristics uSability Evaluation tool) for games, which allows a rebuild of heuristic guidelines based on metadata selection in order to obtain a customized list for every real evaluation case. The usage of these new rebuilt heuristic guidelines allows an explicit attendance to a wide range of usability aspects in games and a better detection of usability issues. We preliminarily evaluate MUSE with an analysis of two different games, using both the Nielsen’s heuristics and the customized heuristic lists generated by our tool.Unión Europea PI055-15/E0
