Early Usability Evaluation in Model-Driven Video Game Development

Usability is considered a relevant quality factor in video games. However, usability evaluations are usually performed too late in the game development lifecycle. We present a usability evaluation strategy that can be used in early stages of model-driven video game development approaches. The usability evaluation is based on a Video Game Usability Model, which extends the usability characteristic of the ISO/IEC 25010 (SQuaRE) standard by incorporating measurable attributes and measures related to the video game domain. The traceability established between the models that are produced in a modeldriven development process and the corresponding source code allows performing usability evaluations on these models, facilitating the early detection/correction of usability problems that may appear in the final video game application. To show the feasibility of this approach, we have performed an early usability evaluation of a video game for the XBOX360 platform.
