"more research and development still needs to be done to set game usability testing methods apart from usability methods used for productivity software or web site development. In this paper, I will detail the history of video games and video game usability, including the qualitative and quantitative importance of the subject; some of the current methods being utilized by game developers to test game usability; and some methods being researched and developed now to impact game usability testing in the future."

"Prototypes have proven to be a good practice in different areas. In the gaming industry, they help identify usability and gameplay issues, among others. The earlier these issues are identified, the less effort is required fixing them. But game assets like graphics are often expensive and are available later on, or even after game functionality has been implemented. Game prototypes are in this case created using lower fidelity visuals. While this technique makes it possible to perform usability tests, it may bias the feedback provided by usability testers. In this paper we investigate how the fidelity of the prototypes used for usability testing influence the feedback provided by testers."

"In this work we present a methodology especially designed to facilitate usability testing for serious games, taking into account the specific needs of such applications and resulting in a systematically produced list of suggested improvements from large amounts of recorded gameplay data. This methodology was applied to a case study for a medical educational game, MasterMed, intended to improve patients' medication knowledge. We present the results from this methodology applied to MasterMed and a summary of the central lessons learned that are likely useful for researchers who aim to tune and improve their own serious games before releasing them for the general public."

Consideration of usability testing for serious, educational games

"In this thesis we present the design and evaluation of a learning game based on the concept of 'stealth learning' and the theory of constructivism, which provides an early introduction to basic programming concepts and procedural literacy to children from 10 years upwards, attempting to provide the highest possible degree of immersion. The evaluation involves a number of tests verifying usability, immersion and motivation, and an attempt to test the transferability of the ingame acquired knowledge to reading pseudocode, the results of which, triggered further reflection on the possibility of adding new layers of complexity and embedding evaluation of learning within the game experience."

Abstract: "As a way to support developers , we propose the creation of specialized tools to deal with accessibility. The hypothesis defined was that it is possible to produce tools that coul d reduce the cost and effort needed to adapt games for people with special needs while achi eving a sufficient level of usability and a pleasant player exper ience . Because of the ambitious of the approach , the goal of the project is to explore if it is feasible through preliminary research . T hree experiments were set up to cover and explore different alternatives , given the diversity of player characteristics and game develop ment approaches . In these experiments we targeted t wo different platforms: a desktop game authoring tool oriented to educators , and a mobile game development framework oriented to programmers . In these experiments we used the to ols developed to produce several games that were also tested by end users . While the project focuses on disability, the ideas proposed can be generalized and applied to support optimizing game interfaces for a wide and diverse audience."

From the abstract: "Objective: We report the design of a trial to assess the educational efficacy of InsuOnline, a game for education of primary care physicians (PCPs). The goal of InsuOnline was to improve appropriate initiation and adjustment of insulin for the treatment of DM. InsuOnline was designed to be educationally adequate, self-motivating, and attractive. Methods: A multidisciplinary team of endocrinologists, experts in medical education, and programmers, was assembled for the design and development of InsuOnline. Currently, we are conducting usability and playability tests, with PCPs and medical students playing the game on a desktop computer. Adjustments will be made based on these results. An unblinded randomized controlled trial with PCPs who work in the city of Londrina, Brazil, will be conducted to assess the educational validity of InsuOnline on the Web. In this trial, 64 PCPs will play InsuOnline, and 64 PCPs will undergo traditional instructional activities (lecture and group discussion). Knowledge on how to initiate and adjust insulin will be assessed by a Web-based multiple choice questionnaire, and attitudes regarding diabetes/insulin will be assessed by Diabetes Attitude Scale 3 at 3 time points-before, immediately after, and 6 months after the intervention. Subjects´ general impressions on the interventions will be assessed by a questionnaire. Software logs will be reviewed. Results: To our knowledge, this is the first research with the aim of assessing the educational efficacy of a computer game for teaching PCPs about insulin therapy in DM. We describe the development criteria used for creating InsuOnline. Evaluation of the game using a randomized controlled trial design will be done in future studies. Conclusions: We demonstrated that the design and development of a game for PCPs education on insulin is possible with a multidisciplinary team. InsuOnline can be an attractive option for large-scale continuous medical education to help imp

"This project involves developing an action-platformer game for the Flash platform. The user controls a character who must progress through levels, while avoiding obstacles, collecting items and fighting many types of enemies. Role-playing game elements such as equipment and upgrades support user customization and varied battle strategies. Developing a successful Flash game involves several factors. Flash games must be simple to get into, yet rewarding to play in both short and long sessions. Flash games must be accessible to a wide audience; both in terms of user preferences and technical limitations. Finally, Flash games must offer something unique to stand out from the crowd, in a market where hundreds of free games are published every month. This report covers the research, design and implementation done to achieve these requirements, in terms of game mechanics, interface, level design, visual design, accessibility options, and replay value. Technical challenges include building, testing and optimizing a game engine and interface from scratch, balancing the game mechanics and difficulty, and structuring the whole development process in a way that enables easy creation of new content. In addition to game design and development, this project also deals with the business aspects of developing online games; how games generate revenue, how they are marketed and distributed, and developing trends in the consumer market. Project success in different areas has been evaluated through usability studies, user ratings and reviews, and vast quantities of usage and distribution statistics. Overall, the project has been a success in terms of user reception and generated revenue, and the final section of this report includes plans for a second game, utilizing and building upon the same game engine and mechanics."
