GUI navigation method for visually -impaired person using three dimensional sound
Disclosed is a system for making visually impaired users to find and point graphical user interface(GUI) objects like windows or buttons using a pointing device.
This system uses existing three dimensional sound system to indicate GUI object's locations to the user. Three dimengional sound system uses several speakers to indicate sound's direction and changes sound's volume to indicate sound's distance from the location of the listener.
This system sets the listener location as the pointer location in the GUI system(ie. the location of the mouse cursor). And it also creates a sound source for each GUI object to indicate locations of GUI objects(fig.1). So that the user is able to know the object's relative direction and distance from the pointer's location by hereing the three dimensional sound. And the user is able to move the pointer toward the object.
When the sound source is set to the center of each object, the user will not know how far the pointer is from the edge of the object. So this system sets the location of a sound source for each GUI object to the nearest point from the pointer's location on the edge of the object(fig.2). So that the user is able to know how far the pointer is from the edge of the object and also which is the direction to enter the object's area by the most direct way.
Usually, there are many GUI objects in a GUI system and the user is con...
