Brain Computer Interface Keyboard
What effect does the environment (BCI, AT device, Computer) have on the accuracy of typing using a BCI keyboard?
Device: Brain Computer Interface Keyboard
Subjects will wear an EEG cap for 1-4 hours (1-2 hours typical) per session and use the brain-computer interface to operate assistive technology. Subjects will be asked to participate in 3 sessions.
- Accuracy of Typing With BCI Keyboard. [ Time Frame: mean score from 3 sessions over 29 days ]
Accuracy for the sentence typed in each environment was calculated as the percentage of characters for which the result character matched the target character. The target characters were determined based on the next character needed to complete the sentence to be copied. In the case of errors, the next character was therefore a backspace to correct the error. The target characters were modified by subject comments to account for errors in selecting the next character.
Once sentence was typed in each environment in each session on a separate day. From the three repeated sessions, there were therefore 9 total sentences per subject with 3 measures for each environment. These were treated as repeated measures for the analysis.
