The Effect of Motion in AAC Displays on Visual Attention and Learning
This study will investigate the effect of targeted motion in AAC displays on visual attention and learning by individuals with developmental disabilities in order to improve the design of AAC systems to enhance communication.
Sessions would occur for about 60 minutes. Study visits will take place at our research lab at Pennsylvania State University. We schedule sessions at your convenience, depending on your schedule. During each visit, you will complete a series of tasks while looking at picture symbols on a computer screen. The tasks will include pointing to the pictures and describing what you see when the research assistant instructs you to do so. While you look at the screen, a small eye tracking device that uses extremely low-level infrared light to record where you are looking will be attached to the monitor . The amount of infrared light is smaller than that found in the typical TV remote and is far below federal safety requirements. We will videotape the session as well so that the process can be studied more closely.
