Abstract
The menu is an important interface component, which appears
unlikely to be completely superseded by modern search-based approaches.
For someone who is unable to attend a screen visually,
however, alternative non-visual menu formats are often problematic.
A display is developed in which multiple concurrent words
are presented with different amounts of onset asynchrony. The effect
of different amounts of asynchrony and word length on task
durations, accuracy and workload are explored. It is found that total
task duration is significantly affected by both onset asynchrony
and word duration. Error rates are significantly affected by both
onset asynchrony, word length and their interaction, whilst subjective
workload scores are only significantly affected by onset asynchrony.
Overall, the results appear to suggest that the best compromise
between accuracy, workload and speed may be achieved
through presenting shorter or temporally-compressed words with
a short inter-stimuli interval.
