The prevalent design metaphor of voice-activated personal assistants (VAPAs) mimicking human-human conversation, while intuitive, may inadvertently create barriers for visually impaired users. This user-centred design research insight is drawn from a 2019 study published in Academic Publication. Using Qualitative document review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Critically evaluate the dominant design metaphors used in your projects, especially those intended for broad user bases, to ensure they do not inadvertently exclude specific user groups.

Key Findings
- 01VAPA design guidelines exhibit significant commonalities.
- 02A core assumption underlying these guidelines is that VAPA interfaces should emulate human-human conversation.
- 03This conversational metaphor may not fully address the unique needs and interaction patterns of visually impaired users.
Application
Design takeaway
Critically evaluate the dominant design metaphors used in your projects, especially those intended for broad user bases, to ensure they do not inadvertently exclude specific user groups.
How to apply
When designing voice interfaces, consider how users who cannot rely on visual cues might interact with the system. Explore non-conversational modes of interaction, such as structured commands or auditory feedback beyond spoken words.
Project actions
- 01When choosing a metaphor for your design, think about who might be excluded by it.
- 02Consider how users with different abilities might interact with your product and design for those scenarios.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Addresses a critical gap in understanding VAPA design for a specific user group.
- +Critically examines a widely adopted design metaphor.
Limitations
The study only reviewed written guidelines, not the actual user experience or the internal design processes of the companies.
Reliability & validity
The qualitative nature of the document review provides rich insights but may be subject to researcher interpretation. The findings' generalizability to all VAPAs and all visually impaired users would require further empirical testing with diverse participants.
Think critically
To what extent does the 'human-human conversation' metaphor truly serve the needs of all users, and what alternative metaphors or interaction models could be more universally beneficial?
Design Principles
"Design metaphors should be rigorously tested for their inclusivity and effectiveness across diverse user populations, rather than relying on assumed intuitiveness."
Understanding the underlying metaphors guiding VAPA design is crucial for ensuring these powerful tools are truly accessible. By critically examining these metaphors, designers can identify and mitigate potential constraints, leading to more inclusive and empowering user experiences for all.
What This Means for Your Design
The way we design voice assistants often makes them sound like people talking to people. This is easy for most people, but it might not be the best way for people who can't see well to use them. We need to think about different ways to design them so everyone can use them easily.
How to use in your project
- 1.Reference this study when discussing the choice of interaction metaphor for your product, particularly if it involves voice or aims for broad accessibility.
- 2.Use the findings to justify exploring alternative interaction methods beyond standard conversational models.

Paragraph starter
The prevalent design metaphor of voice-activated personal assistants (VAPAs) mimicking human-human conversation, as evidenced by vendor guidelines (Branham & Roy, 2019), may inadvertently create barriers for visually impaired users. This research suggests that designers should critically evaluate such metaphors and explore alternative interaction paradigms to ensure universal usability and empower all users.
