Abstract:
1. A method, comprising: responsive to a change in position of a volume control element from a first position to a second position, causing a linear rise in volume level corresponding to the change in position of the volume control element from the first position to the second position; responsive to a change in position of the volume control element from the second position to a third position, causing an asymptotic rise in the volume level corresponding to the change in position of the volume control element from the second position to the third position; and activating a visual indicator corresponding to the changes in position of the volume control element, wherein the brightness of the visual indicator increases linearly in correlation with the change in position of the volume control element from the first position to the second position that causes a linear rise in volume level, and the brightness of the visual indicator increases asymptotically in correlation with the change in position of the volume control element from the second position to the third position that causes an asymptotic rise in volume level.
