TL;DR

This paper develops a novel set of design recommendations for creating accessible Visual Programming Tools tailored for children with Autism Spectrum Condition, based on expert interviews and literature review.

Contribution

It introduces a new, validated set of design guidelines specifically aimed at improving accessibility of VPTs for children with ASC and cognitive impairments.

Findings

Validated recommendations through expert interviews

Identified additional guidelines from literature review

Proposed a comprehensive set of design principles for accessible VPTs

Abstract

Visual Programming Tools (VPTs) allow users to create interactive media projects such as games and animations using visual representations of programming concepts. Although VPTs have been shown to have huge potential for teaching children with cognitive impairments including those with Autism Spectrum Condition (ASC), research has shown that existing VPTs may not be accessible to them. Therefore, this study proposes a set of recommendations for the design of accessible VPTs for children with ASC. Recommendations were initially gathered and validated by interviewing experts (n=7). The interviews were thematically analysed to identify recommendations. A second set of interviews with a subset of the initial experts (n=3) was then conducted to validate the gathered recommendations. An examination of the available literature was then conducted to identify additional recommendations for the design of VPTs. These recommendations arose from those used for the design of other interactive applications for children with ASC (e.g. virtual environments, serious games) and not identified as part of those the initially gathered from interviews. A novel set of recommendations for the design of VPTs for children with ASC and additional cognitive impairments has been defined as the result of this study.
