Effects of Picture Prompts Delivered by a Video iPod on Pedestrian Navigation

Abstract

Transportation access is a major contributor to independence, productivity, and societal inclusion for individuals with intellectual and developmental disabilities (IDD). This study examined the effects of pedestrian navigation training using picture prompts displayed through a video iPod on travel route completion with 4 adults with IDD. Results indicated a functional relation between picture prompts on the video iPod and pedestrian navigation skills to and from various locations. Maintenance data indicated all participants continued navigating trained routes for up to 232 days using the video iPod. Generalization measures to untrained routes were positive. Social validity data suggested iPod training was useful and practical for teaching independent pedestrian navigation skills. Last, limitations, suggestions for future research, and implications for practice were provided.

A Collaborative Action Research about Making Self-Advocacy Videos with People with Intellectual Disabilities

“…Another study concluded that using iPhones to send video captions when participants were lost was an effective strategy to help them find their way back home (Purrazzella & Mechling, 2013). Similarly, Kelley, Test and Cooke (2013) showed that the use of picture prompts with iPods for pedestrian navigation had a positive effect on travel route completion for people with ID (Kelley et al, 2013). A study has suggested that the combination of some forms of VBI, such as video modeling with iPods, has proven to be a useful strategy to teach communication skills (van der Meer et al, 2011) to people with ID.…”

Examining Augmented Reality to Improve Navigation Skills in Postsecondary Students With Intellectual Disability

“…Researchers suggest that mobile devices can help students with disabilities live as independently as possible by mastering skills such as finding direction and using public transportation (Cihak, Fahrenkrog, Ayres, & Smith, 2010;Kelley, Test, & Cooke, 2013;.…”

“…Using a multiple probe across participants design, researchers found that the video iPod was effective at facilitating independent pedestrian travel in students with ID with one participant continuing to navigate independently for 232 days during the maintenance phase. Mechling andSeid (2011), Cihak et al (2010), and Kelley et al (2013) incorporated the use of handheld devices (i.e., PDA or video iPod) to improve independence and travel skills. However, each of these interventions lacked spontaneity and required prior planning.…”

A Study of The Effects of Multimedia Dynamic Teaching on Cognitive Load and Learning Outcome

“…Kelley et al (2013) concluded that both teachers and students would expect to realize the outcome and the acquired value after the teaching and learning. The evaluation of understanding and value of such outcome was instructional assessment, in which the teaching activities contained the teaching of teachers and the learning of students.…”
