These tools allows game developers to easily introduce configurable features of hearing accessibility in a unified and consistent way, such as visualization of sound directionality and more configurable subtitles.

The "bubble" (3D vectorscope) is a solution to the graphical representation of sound in a three-dimensional space, a sphere whose surface is dynamically deformed according to the direction and intensity of the sounds, as a radar.

The visual compass is included as a versatile tool that represents a greater amount of information simply and comfortably.

The subtitles, simple in appearance, are very important elements because of the wide use in the majority of the games.
