Short answer

Designers must actively involve the target user group, especially vulnerable populations, throughout the entire design and development lifecycle to ensure the final product meets their specific needs and enhances their independence.

Field: User-Centred Design

Method: Mixed Methods Study
Sample: 9 participants
Evidence: Moderate effect

Actively involving individuals with complex care needs and stakeholders in the design process of a virtual assistant leads to a more usable and appropriate technology. This user-centred design research insight is drawn from a 2026 study published in JMIR Human Factors. Using Mixed methods study with 9 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must actively involve the target user group, especially vulnerable populations, throughout the entire design and development lifecycle to ensure the final product meets their specific needs and enhances their independence.

Inclusive Co-Design Enhances Virtual Assistant Usability for Complex Care Needs

Actively involving individuals with complex care needs and stakeholders in the design process of a virtual assistant leads to a more usable and appropriate technology.

JMIR Human Factors · 2026

Key Findings

01The inclusive design process allowed for adaptation and refinement of the collaborative approach.
02Co-researchers' involvement provided valuable insights into usability and appropriateness of the virtual assistant.
03The Vision in Product Design method and design thinking approach facilitated the inclusive co-design process.

Application

Design takeaway

How to apply

When designing any product intended for a specific user group, especially those with potential accessibility challenges, conduct user research and involve them in iterative design and testing phases.

Project actions

01When designing for a specific user group, consider how you can involve them in your design process, even in a small way.
02Think about how different user needs can influence design decisions.

Method & Evidence

AimTo investigate the experiences of co-researchers with mild intellectual disability or autism spectrum disorder and other key stakeholders regarding the inclusive design process for a digital tool for individuals with complex care needs.

MethodMixed Methods Study

ProcedureThe study involved semistructured interviews and group discussions with nine consortium members (including three co-researchers) after each of the project's five work packages. An adapted questionnaire with Likert scales and open-ended questions was used during interviews. Data analysis involved thematic analysis for qualitative data and descriptive statistics for quantitative questionnaire data.

Sample9 participants

ContextDevelopment of a virtual assistant for individuals with complex care needs.

Variables

IVInvolvement of co-researchers in the design process.

DVUsability and appropriateness of the virtual assistant.

CVDesign methodologies used (Vision in Product Design, design thinking), project work package structure.

Strengths & Limitations

Strengths

+Employs a mixed-methods approach for comprehensive data.
+Focuses on a vulnerable and often underrepresented user group.

Limitations

Small sample size, specific context of virtual assistant development, potential for researcher bias in qualitative data interpretation.

Reliability & validity

Reliability is enhanced by using consistent interview protocols and questionnaires across work packages. Validity is strengthened by triangulating qualitative and quantitative data, and by the direct involvement of end-users in the research process.

Think critically

How might the power dynamics between researchers and co-researchers with disabilities influence the design outcomes?

Design Principles

"Involve end-users with diverse needs throughout the design process to ensure product relevance and usability."

This highlights the critical importance of User-Centred Design (UCD) principles in developing assistive technologies. It demonstrates that understanding and integrating the needs of diverse user groups, especially those with complex care requirements, is paramount for creating effective and accessible digital tools.

What This Means for Your Design

If you want to make something useful for people, especially those who might have trouble using regular technology, you need to ask them what they need and let them help you design it from the start.

How to use in your project

1.Use this insight to justify your user research methods, particularly if you are involving specific user groups in your design process.
2.Reference this study when discussing the importance of iterative design and user feedback in achieving successful product development.

Paragraph starter

This study underscores the critical role of inclusive co-design in developing assistive technologies. By actively involving end-users with complex care needs throughout the design process, as demonstrated by the development of a virtual assistant, designers can ensure that the final product is not only functional but also highly usable and appropriate for its intended audience. This iterative approach, incorporating user feedback at multiple stages, is essential for creating solutions that genuinely enhance independence and quality of life.
