| augmented reality | Behavioral | The participants will be wearing an EEG cap and Augmented Reality headset (AR-based EEG-guided system) for 10 sessions with a licensed occupational therapist, provided in addition to usual rehabilitation care (either in inpatient rehabilitation or at home). These sessions will focus on activities of daily living that the participants want to practice. All sessions will last approximately 1 hour. These sessions will be scheduled around the existing therapy schedule to cause the least amount of interference with planned clinical activities. |
| Measure | Description | Time Frame |
|---|---|---|
| Accuracy; indicated by percent agreement between participant report and EEG-based assessment of neglect | 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; | week 4 |
| Reliability; indicated by correlation coefficient between two consecutive sessions of EEG recording | number of consecutive sessions attaining Pearson correlation coefficient r greater than.10 | week 4 |
| Measure | Description | Time Frame |
|---|---|---|
| Technology Satisfaction; indicated by a mean score of 3 or higher on the Quebec User Evaluation of Satisfaction with Assistive Technology | 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; |

Recorded EEG data may be disseminated to collaborators, other researchers, or the general public, for instance via DScholarship@Pitt: University of Pittsburgh Institutional Repository or through Pitt Box. At this time, there are no specific external parties. If in the future, access to data is requested, any identifying data to will be removed from the EEG data to protect participants' privacy.
