Although video games have become interesting entertainment tools for millions of people, gamers with mobility impairment face difficulties to be able to interact with games successfully because of impairment conditions. Even though developers working in the area of disbility provide special games, tools, and devices support interacting with video games, there is a lack of sufficient tools and devices that are compatible with certain motor impairment conditions. EEG-headset based brain computer interface system is alternative suggested tool which can support mobility gamers by using their brain activities, facial muscles, and eye movement to interact with games. This paper aims to examine and investigate the NIA controller's capability, which use EEG-headset, with two methods providing game accessibility. The first method reduces some keyboard switches and uses the NIA controller, and the other method eliminates the entire keyboard switches and uses only the NIA controller. The result shows that playing games with using the NIA controller and one- keyboard switch is done in successful and precise way. In contrast, playing games with using only the NIA controller could be done successfully but less precisely. Our conclusion is that the NIA controller could be combined with other accessible tools to improve the accessibility of games.

VR applications provide an opportunity to study a variety of new applications. One of the focus areas of the media convergence, games and media integration (McGMI) program is to develop new media applications for the visually impaired population. We are particularly interested in developing applications which are at the same time interesting for the sighted population as well-hence the title-crossover applications. Bonnie Snyder, who has been working with the visually impaired population for more than twenty years, visited a group of students early in the Fall 2008 As many typical applications are geared toward sighted population, the cost of software and hardware systems tend to be a lot higher. In addition, several games, developed for primarily the sighted, provide minimal interaction for the blind. Although this issue remains a topic of discussion in both IEEE VR and ISMAR and related conferences, much more can be done. We used this as motivation and developed three applications for both the sighted and the visually impaired population (a) haptic chess program combines PHANTOM force feedback interaction with OpenAL audio; (b) Simple hand movement recognition on iPhone provides a hierarchical menu application; (c) Barnyard fun program uses interesting animal-sound feedback to facilitate spatial selection. In future, we expect to conduct testing of these applications in Denver Museum as possible.
