Reusable game interfaces for people with disabilities

Abstract

Computer games are a very popular media today, spanning across multiple aspects of life, not only leisure but also health or education. But despite their importance their current level of accessibility is still low. One of the causes is that accessibility has an additional cost and effort for developers that is in many cases unaffordable. As a way to facilitate developers' job, this work proposes the creation of specialized tools to deal with accessibility. The hypothesis defined was that it was possible to produce tools that could reduce the input needed to adapt the games for people with special needs but achieving a good level of usability, resulting in a reduction of the cost and effort required. As game development tools and approaches are heterogeneous and diverse, two case studies were set up targeting two different platforms: a high level PC game authoring tool, and a low-level Android game programming framework. Several games were developed using the tools developed, and their usability was tested. Initial results depict that high usability levels can be achieved with a minimum additional input from the game author.
