Spectrograms of one of the audio cues used in the experiment with its different variations based on location.
The word played was "Bakbuk", meaning bottle.

Illustration of the algorithm in both conditions—Original (left) and Interchanged (center), and its implementation in the test environment (right).
Fig 3.
Cumulative success rates of the individual participants by trial.
Dotted lines represent participants who are blind, dashed lines represent visually impaired.
Fig 4.
Comparisons between baseline and test in both conditions.
Table 1.
Mean success rates of the participants in the baseline and test stages.
Fig 5.
Negative cumulative number of mistakes per trial in the training stage.
Table 2.
Average training durations for both conditions.
Fig 6.
Distribution of success rates in the different cells per condition.
Original condition (top left), Interchanged condition (top right), Flipped diagram of the interchanged condition (bottom left). The flipped diagram represents the same data, with the axis flipped, so that the grid matches the auditory representation of the original condition.
Fig 7.
Success rates of baselines and tests for each condition divided by axis—z axis (left) and y axis (right).
Fig 8.
Heatmaps of the success rate per cell location per axes in the original condition (left) and the interchanged condition (flipped diagram) (right). The left and right grids are aligned to match in their auditory representation.
