A user-centred design framework for the development of speech and language therapeutic toys

Therapy in early childhood is facilitated through toys and play. While mainstream toys are designed for children, therapeutic toys need to satisfy requirements from clinicians, caregivers, and children. The study presented in this paper investigated the challenges that 22 international toy designers encounter during the design process and whether support is required when developing products for speech and language therapy, through a mixed-method approach. Results show that considerable challenges are encountered during the early design stages. Nonetheless, the toy design process remains unsupported, while no support is available for designers to consider therapeutic needs. Based on the feedback received, eleven requirements were identified upon which a user-centred design support framework was proposed to assist toy designers during the task clarification stage, taking into account the affordances that therapeutic toys should have without inhibiting the creative process.peer-reviewe

Research funded projects are often concerned with the development of proof-of-concept products. Consequently, activities related to verification and validation testing (VVT) are often not considered in depth, even though various design iterations are carried out to refine an idea. Furthermore, the introduction of additive manufacturing (AM) has facilitated, in particular, the development of bespoke medical products. End bespoke products, which will be used by relevant stakeholders (e.g. patients and clinicians) are fabricated with the same manufacturing technologies used during prototyping. As a result, the detailed design stage of products fabricated by AM is much shorter. Therefore, to improve the market-readiness of bespoke medical devices, testing must be integrated within the development from an early stage, allowing better planning of resources. To address these issues, in this paper, a comprehensive VVT framework is proposed for research projects, which lack a VVT infrastructure. The framework builds up on previous studies and methods utilised in industry to enable project key experts to capture risks as early as the concept design stage.peer-reviewe
