Mobile devices emergent development further enlivens Augmented Reality Technology (AR). AR possess the ability to shift the way community see the world by hauling graphics away from screen display and mix it with real environment. However small screen barrier remains as limitation in restricting the development of mobile games especially in mobile audio based games development. This is maybe due to the limited information that can be conveyed by audio. However, acoustic modality can enlighten small screen limitation by serving as alternative modality without distracting user's eye attention when running mobile application. Current games use audio in 4 different aspects namely music, effect, input and speech. Speech can be divided into two categories which is speech and non-speech sound where speech is best use in transmitting information while nonspeech sound is most appropriate towards speed and language independent. This paper proposed an approach using nonspeech sound as audio input channel (acoustic modality) for development of audio based games in AR environment that can enhance audio information presentation. The precautionary measurement has been discussed to contend with challenges and limitations. © 2012 IEEE.
