case_images: The eye gaze board was set up with a four-image array. This is an example of an array of emojis showing mad, tired, happy, and sick.. Pictures and photos were laminated, and Velcro was used to change the options available as responses when the participant was asked questions. The array always included four pictures/photos positioned in one of the four corners of the eye gaze board.

case_images: A 18 x 14 inch clear acrylic AAC eye gaze board, or E-Tran frame, was set up to display an array of four pictures (photos and/or images) at a time, with one image at each corner (see Figure 1). Pictures were not always put on the board in the same location, and the location for a given picture was switched during each session and from session to session (see Figure 1).
case_images: Number of responses made per session when asked choice-based questions using the eye-gaze communication board during the AAC treatment sessions only.. The eye-gaze board was introduced during session 14; therefore, baseline sessions 1-13 are not included in this graph. For sessions 14-29, the participant responded using the eye gaze board between 1 and 5 times per session. While she may have also responded using a yes/no blink response, that data is not included in this graph. The trendline was calculated using the least squares method to find the line of best fit and is included to help with visual interpretation of change over time.. AAC, augmentative and alternative communication.

case_images: Figure 2), the trendline (calculated using the least squares method to find the line of best fit) showed a positive slope and suggested a small increase over time. For the sessions that included the eye gaze board (sessions 14-29), the participant responded to caregiver questions using this system at least once during all sessions.
case_images: Total number of Yes/No (Blink) and eye-gaze responses per session.. The duration of each session in minutes is included as a data label above each bar. The gray bars indicate yes/no eye gaze responses, and the black bars indicate responses using the eye gaze board. The bars are stacked to show the types of responses during each session. The eye gaze board was introduced during session 14, so there was no way for the participant to respond using eye gaze prior to that session.

case_images: A visual analysis of the of the graphed data revealed notable session-to-session variability (see Figure 3). While statistical tests were not conducted, there does not appear to be a trend or pattern between the session length and number of responses using either modality (see Figure 3).
case_images: Ratio of responses using all communication methods (Yes/No Blink and eye gaze board responses) to all questions asked.. The trendline was calculated using the least squares method to find the line of best fit and is included to help with visual interpretation of change over time.
