In the current version of soundscape mGIS, we have identification with speech. Whenever the mouse enters into a new region, the program identifies the region and the speaker enunciate the name of the region and be silent until the mouse moves inside the same region. In order to make this soundscape feature more expressive for a blind user we can include some audio cues.
Michal and I talked about this today and came up with the idea that apparently we need to have three different audio cues (naturalistic or musical or both):
1) A tiny little sound that represents entering into a new region. (also can be thought of region changed)
2) One sound that can be played continuously while the mouse is hovering inside a region. Our current simple yellowstone park map basically has two different types of regions:
a)Water (including river, lakes and creeks),
b)Park base or land.
So for type 2 we need to make two different kinds of sounds that can represent these regions more significantly.
This website could be helpful for finding some sample audio cues: water falling, inside the forest, birds singing etc. Some of them are naturalistic and some are composed with musical instruments.
