Personalization of Visual Scene Displays: Preliminary Investigations of Adults with Aphasia, Typical Females across the Age-Span, and Young Adult Males and Females.

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, are 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.

Effectiveness and Utility of Visual Scene Displays as Communication Supports for Adults and Children With Complex Communication Needs: Perspectives of Clinicians and Researchers.

Purpose The aims of this research study were to describe the perspectives of clinicians and researchers regarding the effectiveness of visual scene displays (VSDs) as communication supports in order to inform the translation of research to clinical practice. Method An online survey was completed by 298 clinicians and nine VSD researchers. Participants rated the effectiveness of VSDs in supporting a variety of communication functions and their strength of agreement regarding statements of VSD utility.

Clinical and Research Perspectives on Visual Scene Displays.

Purpose The purposes of this study were to measure the perceptions of speech-language pathologists (SLPs) and researchers regarding the design of visual scene displays (VSDs) and to investigate the perceived difficulties of SLPs in regard to the acquisition and programming of VSDs. Method We recruited 270 SLPs and nine researchers who focus on VSDs to complete an online survey. The SLP survey addressed both perception of VSD design and difficulties associated with implementing these images as communication supports in the clinical realm.

Visual processing patterns of adults with traumatic brain injury when viewing image-based grids and visual scenes.

Many individuals with traumatic brain injury (TBI) rely on augmentative and alternative communication (AAC) supports to meet functional communication needs. The use of images to display message content may be advantageous for this population, given deficits in literacy, visual processing, and cognition. Grid and visual scene displays are two options for presenting images within AAC systems.

Identification and Expression of Themes Depicted in Visual Scene and Grid Displays by Adults With Traumatic Brain Injury.

Purpose The study purpose was to compare the speed and accuracy with which people with traumatic brain injury (TBI) identified themes depicted in visual scene and grid displays. Additionally, we compared the verbal responses associated with the 2 display types to determine whether adults with TBI tended to produce more action or naming messages. Method Thirteen adults with and 13 without TBI viewed grid and visual scene displays matched for content and theme.

Designing effective AAC displays for individuals with developmental or acquired disabilities: State of the science and future research directions.

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.

Using Images With Individuals With Aphasia: Current Research and Clinical Trends.

Purpose: Visuographic supports in the form of images are utilized during assessment and treatment for individuals with aphasia to supplement speech, language, and cognitive losses limiting communication. Clinicians rely on prior experience and intuition to make decisions regarding image-based support design and selection (e.g.

The effect of human engagement depicted in contextual photographs on the visual attention patterns of adults with traumatic brain injury.

Unlabelled: Photographs are a frequently employed tool for the rehabilitation of adults with traumatic brain injury (TBI).

Noun representation in AAC grid displays: visual attention patterns of people with traumatic brain injury.

Clinicians supporting the communication of people with traumatic brain injury (TBI) must determine an efficient message representation method for augmentative and alternative communication (AAC) systems. Due to the frequency with which visual deficits occur following brain injury, some adults with TBI may have difficulty locating items on AAC displays. The purpose of this study was to identify aspects of graphic supports that increase efficiency of target-specific visual searches.

Measurement of the visual attention patterns of people with aphasia: a preliminary investigation of two types of human engagement in photographic images.

The focus of this investigation was to examine the visual attention patterns of adults with aphasia on task-engaged contextualized images in which a human figure was engaged with the context of the image and camera-engaged contextualized images in which a human figure was looking forward toward the camera. Analysis revealed that adults with aphasia tend to fixate rapidly and frequently on human figures in contextualized images regardless of the type of engagement in the image. In addition, they responded to engagement cues when viewing task-engaged contextualized images by fixating more frequently and more rapidly on the object area of interest for these images than for camera-engaged contextualized images.
