Fig. 6From: How to optimize switch virtual keyboards to trade off speed and accuracyExperimental results. Proportion of entry errors as a function of experimental session. Each curve corresponds to a different participant and different symbols indicate the cursor duration (milliseconds) that was used for that session. Error bars indicate plus and minus one standard error of the proportion. For most statistics, these error bars are quite small because a session involved entering around 1,700 charactersBack to article page
