Evaluation of an Affordance-Based Requirements Generation Tool for Speech And Language Therapeutic Toys

Abstract

Task clarification poses various challenges to designers as they need to understand the different needs of users before translating the requirements into specifications and aptly conceiving product concepts in the subsequent design stage. This paper presents a descriptive study for the evaluation of a framework and its implementation as a computer-based prototype tool, proposed to assist designers in generating and understanding affordance-based requirements for speech and language therapeutic toys. Results show that early design support is beneficial to both experienced and novice designers.

Requirements elicitation in board game design for children with developmental language disorder (DLD)

“…In a previous study by Balzan (2022) a set of twelve elements were identified which provide designers with explicit knowledge regarding the considerations which should be done when eliciting requirements for a conventional SALTT. Balzan et al (2022) argue that each element is vital for the design of a SALTT and an absence of any of the components will negatively impact the effectiveness and usefulness (referred to as the potential) of an artefact being designed for use in DLD therapy.…”
