Here we share resources to support clinical evaluation of potential brain-computer interface (BCI) users and inclusion of people with disabilities as research participants.
For additional information about BCI, as well as handouts and communication supports for people with severe speech and physical impairments, please see our page for end-users and families.
The OHSU BCI Sensory/Cognitive/Communication Screen is designed to assess the requisite skills for use of a visual-interface spelling BCI. These include visual acuity (for target discrimination and reading text), ocular motility to direct gaze to stimuli, and the ability to maintain fixation on stimuli, as well as cognitive and communication skills for attention to stimuli, understanding and following instructions, literacy, and executive functioning. The revised version, available below, includes questions for caregivers and adapted informed consent procedures.
Read our article in Disability and Rehabilitation: Assistive Technology about the development of the original screening protocol.
Learn about the revised screen in this poster from the 2018 International BCI Meeting.

The flipbook is designed to be printed double-sided and spiral-bound at the top edge. The black rectangle should be cut out of each page,
The OHSU BCI User Feedback Questionnaire uses augmentative and alternative communication-based techniques to make it easier for people with severe speech and physical impairments to provide feedback on their experience using BCI (or other assistive technologies).
Read our article in Brain-Computer Interfaces about the development and testing of the questionnaire.
