Short answer
When designing voice assistants for mental health, err on the side of functional clarity and empathetic tone rather than striving for full human imitation, especially in sensitive therapeutic dialogues.

While voice assistants offer potential for mental health support to homebound older adults, their perceived human-likeness can shift from helpful to uncanny depending on the context of the interaction. This human factors research insight is drawn from a 2024 study published in Designing Interactive Systems Conference. Using Participatory design study with 13 participants (6 older adults, 7 caregivers), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing voice assistants for mental health, err on the side of functional clarity and empathetic tone rather than striving for full human imitation, especially in sensitive therapeutic dialogues.
Human-like voice assistants can be perceived as uncanny in mental health interventions for homebound older adults.

Key Findings
- 01Participants identified specific aspects of human-likeness that were perceived as helpful, enhancing engagement and comfort.
- 02Other aspects of human-likeness were perceived as uncanny, leading to discomfort and potential distrust in the mental health intervention.
- 03The context of the dialogue significantly influenced the perception of human-likeness.
Application
Design takeaway
When designing voice assistants for mental health, err on the side of functional clarity and empathetic tone rather than striving for full human imitation, especially in sensitive therapeutic dialogues.
How to apply
During user testing of voice assistant prototypes for mental health, specifically probe users about their feelings regarding the assistant's 'personality' and 'human-ness' in different conversational contexts.
Project actions
- 01When designing for vulnerable user groups, always involve them directly in the design process.
- 02Consider the emotional impact of design choices, not just functional aspects.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized a participatory design approach, directly involving end-users.
- +Focused on a specific, underserved user group (homebound older adults).
Limitations
The findings are specific to older adults and mental health; results might differ for younger users or other application domains.
Reliability & validity
Reliability could be enhanced by using standardized questionnaires for user perception. Validity is supported by the participatory design method, which ensures the research is grounded in user needs and experiences, but the small sample size may limit generalizability.
Think critically
To what extent should voice assistants for mental health aim to mimic human conversation, and what are the ethical considerations of blurring the lines between human and artificial interaction in therapeutic settings?
Design Principles
"The uncanny valley effect can be a significant barrier in human-computer interaction, particularly in emotionally sensitive domains. Design should aim for a comfortable and functional level of anthropomorphism."
Designers must carefully consider the degree of anthropomorphism in voice assistants intended for sensitive applications like mental healthcare. Striking the right balance is crucial to ensure user acceptance and therapeutic effectiveness, avoiding the creation of discomfort or distrust.
What This Means for Your Design
Making a voice assistant sound too much like a real person can sometimes be creepy, especially when it's supposed to help with mental health problems. Designers need to be careful about how human-like they make it.

Paragraph starter
Research indicates that the degree of human-likeness in voice assistants can significantly impact user perception, particularly in sensitive contexts such as mental health interventions for homebound older adults. While some human-like qualities can enhance engagement, others may lead to an 'uncanny' feeling, undermining trust and therapeutic effectiveness. Therefore, designers must carefully balance functional clarity and empathetic tone with anthropomorphism to ensure user acceptance and positive outcomes.
