“…Thus, image preference was inferred through gaze location. Visual attention has been used in previous AAC research to indicate a selected choice and allow for investigation of the cognitive processing associated with AAC displays (Thiessen et al, 2017).…”

“…The final limitation worthy of note was that participants were not expected to physically access their image choice from the four images in the display; rather, only visual fixation duration was measured. Although researchers have employed this methodology in prior research (Thiessen et al, 2017), it may not render data that completely represent the choices of participants in the way of physical selection either through pointing or by use of external aids (e.g., mouse click, response box selection) would. In addition to potential issues with the selection method, the methodology only captured preference at one moment in time.…”

Visual scene displays (VSDs) are becoming an increasingly popular method of message representation within augmentative and alternative communication (AAC) supports; however, design factors can influence the effectiveness of these images as communication supports. One issue that has come to light in recent years is the fact that selecting personalized VSDs, which depict the person with complex communication needs or an individual with whom they are familiar, is preferred over generic VSDs, which depict unfamiliar individuals. Although personalization is likely an important factor in the usability of VSDs, these images may be difficult for clinicians to obtain. As such, compromises must be identified. The purpose of this study was to explore the effects of controlling personal relevance factors (i.e., age and gender of the people depicted in generic VSDs) on the image preference patterns of adults with and without aphasia. Results from three very preliminary study summaries indicate that gender and age are both mitigating factors in image preference, as males tended to indicate preference for VSDs containing males over those containing females. In addition, females tended to indicate preference for females of a similar age depicted in VSDs.

“…Beyond the research with individuals with severe chronic aphasia, researchers have also begun to investigate the potential benefits of VSDs for adults with TBI (Brown, Hux, Knollman-Porter, & Wallace, 2016;Thiessen, Brown, Beukelman, Hux, & Myers, 2017;Wallace, Hux, & Beukelman, 2010). For individuals with TBI, the rationale for the use of VSDs is grounded in their potential to minimize the cognitive burden associated with AAC use.…”

“…Task-engaged people in VSDs also play the important role of completing an action (e.g., taking a cake out of an oven). Thiessen, Brown, Beukelman, Hux, and Myers (2017) examined the preferences of a group of adults with TBI to three image types: line-drawn icons, decontextualized photos, and visual scenes. Results from that study indicate that adults with TBI preferred visual scenes to line drawings or decontextualized photos for the representation of action messages.…”

This paper reviews research on the impact of AAC display variables on visual attention and performance of children with developmental disabilities and adults with acquired conditions, and considers implications for designing effective visual scene displays (VSDs) or grids. When using VSDs with children with developmental disabilities or adults with acquired conditions, research supports the use of personalized photo VSDs that include familiar people engaged in meaningful activities, with navigation bars with thumbnail VSDs, located adjacent to the main VSD. Adults with acquired conditions seem to benefit from the inclusion of text boxes adjacent to the scene. Emerging evidence supports the use of motion to capture visual attention to VSDs (video VSDs) or to specific elements in VSDs. When using grid displays with children with developmental disabilities, research supports the use of spatial cues and clustering based on internal symbol color to facilitate visual searching and selection. Background color does not seem to facilitate searching for symbols on smaller displays and may actually distract children from processing the meaningful components of symbols. Preliminary research suggests that the organization of onscreen keyboards and the number, types, and pairings of symbols in grids may impact performance of adults with acquired conditions. Directions for future research are discussed.
