Auditory Menu Navigation Performance with Spearcon Enhancements

Dianne K. Palladino of the Georgia Institute of Technology conducted a study with 28 undergraduates navigating two-dimensional auditory menus. The data compares navigation speed between text-to-speech (TTS) only menus and TTS enhanced with spearcons, which are compressed sound cues. Results indicate navigation was significantly faster with spearcons, with a smaller per-item speed cost as menu length increased.

Use Cases

• Compare auditory menu navigation efficiency based on the described TTS and spearcon conditions.
• Model the relationship between menu length and navigation speed based on the described per-item cost.
• Evaluate the effectiveness of spearcon sound cues for improving performance in non-visual interfaces.

Strengths

• Experimental data from a controlled study involving 28 participants.
• Results show a statistically significant performance improvement for the spearcon condition.

Limitations

• Row count and specific column-level documentation are unknown; field semantics must be inferred after download.
• The dataset license is closed, restricting reuse and distribution.
