Arms & Interventions
augmented reality
Intervention: augmented reality (Behavioral)
Outcomes
Primary Outcomes
Accuracy; indicated by percent agreement between participant report and EEG-based assessment of neglect
Time Frame: 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
Time Frame: week 4
number of consecutive sessions attaining Pearson correlation coefficient r greater than.10
Secondary Outcomes
- Program Satisfaction; indicated by mean score of 3 or greater on the Client Satisfaction Questionnaire(week 4)
- Technology Satisfaction; indicated by a mean score of 3 or higher on the Quebec User Evaluation of Satisfaction with Assistive Technology(week 4)
