Primary Outcome Measures

Name	Time	Method
Accuracy; indicated by percent agreement between participant report and EEG-based assessment of neglect	week 4	number of sessions attaining greater than 70 percentage agreement between targets identified by the participant and targets identified by EEG; participants view an augmented reality screen with randomly appearing targets in the field of view; when a target is viewed, the participant presses a keyboard key; immediately after, targets randomly appear on the augmented reality screen while the participant's brain activity is recorded by EEG; EEG detects viewed and neglected targets based on brain signals;
Reliability; indicated by correlation coefficient between two consecutive sessions of EEG recording	week 4	number of consecutive sessions attaining Pearson correlation coefficient r greater than.10

Secondary Outcome Measures

Name	Time	Method
Program Satisfaction; indicated by mean score of 3 or greater on the Client Satisfaction Questionnaire	week 4	number of participants attaining greater than or equal to 90 percentage satisfaction; satisfaction is rated on 8 items with a 4-point likert scale, 4 indicating very high satisfaction; items are summed with total a total score of 32 indicating very high satisfaction;
Technology Satisfaction; indicated by a mean score of 3 or higher on the Quebec User Evaluation of Satisfaction with Assistive Technology	week 4	number of participants attaining greater than or equal to 90 percentage satisfaction; satisfaction is rated on 12 items with a 5-point likert scale, 5 indicating very high satisfaction; items are summed with total a total score of 60 indicating very high satisfaction;
