Defining usability quality metric for mobile game prototype using software attributes

The rapid growth in the development of mobile games to serve various user needs has result in a high competition of software game development industry. Usability is a major quality of mobile game product which significantly affects the player satisfaction. The usability assessment of mobil e game product which is game prototype developed during the production is result from the need of correction in an earlier stage which may help reduction in cost and time development. This research proposes an approach to define an internal usability quality metric for a mobile game prototype developed in a design phase. The proposed metric, classified from software attributes as content, device, and gameplay is defined based on the general suggested usability metric category in ISO/IEC 9126-3 standard and derived from GQM method (Goal Question Metrics). The structure and elements of the metric description are established from the ISO/IEC 15939 standard.
