- Quantitative study using an extended Technology Acceptance Model (TAM).
- Sample
- 79 older adults
- Evidence
- Moderate effect
The successful integration of soft service robots into the lives of older adults is primarily driven by their perceived ease of use, perceived usefulness, and the influence of subjective social norms, rather than their perceived likability or anxiety reduction. This user-centred design research insight is drawn from a 2020 study published in AIS Transactions on Human-Computer Interaction. Using Quantitative study using an extended technology acceptance model (tam). with 79 older adults, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize intuitive design and clear functional benefits over aesthetic appeal or emotional engagement when designing assistive robots for older adults.

Key Findings
- 01Perceived ease of use significantly predicted older adults' intention to adopt and use soft service robots.
- 02Perceived usefulness significantly predicted older adults' intention to adopt and use soft service robots.
- 03Subjective norms significantly predicted older adults' intention to adopt and use soft service robots.
- 04Perceived anxiety did not significantly predict intention to adopt and use.
- 05Perceived likability did not significantly predict intention to adopt and use.
Application
Design takeaway
Prioritize intuitive design and clear functional benefits over aesthetic appeal or emotional engagement when designing assistive robots for older adults.
How to apply
When designing assistive robots for the elderly, conduct user testing focused on task completion efficiency and ease of interaction. Gather feedback on how the robot fits into the user's social context.
Project actions
- 01When researching user needs, ask specific questions about how easy a product is to operate and what problems it solves.
- 02Consider the social context of your design – who else will be affected or have an opinion about it?
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a well-established theoretical framework (TAM).
- +Focuses on a critical and growing demographic (older adults).
- +Investigates a novel technology (soft service robots).
Limitations
The sample size might be small for broad generalizations. The specific technology (soft service robot) might have unique characteristics that influence acceptance differently than other assistive devices.
Reliability & validity
The study's validity is supported by the use of a theoretical model (TAM) and quantitative measurement of user perceptions. Reliability would depend on the consistency of the survey instrument and the controlled experimental conditions.
Think critically
How might the 'softness' of the robot have influenced perceived likability or anxiety, even if these were not significant predictors of adoption? Could different types of soft robots yield different results?
Design Principles
"For assistive technologies targeting older adults, perceived ease of use, perceived usefulness, and positive social norms are stronger drivers of adoption than perceived likability or anxiety."
This research highlights that for assistive technologies like soft service robots to be adopted by older adults, design efforts should prioritize intuitive interfaces and clear functional benefits. Understanding the social context and how peers or family perceive the robot is also crucial for driving acceptance.
What This Means for Your Design
When making robots for older people, make sure they are super easy to use and really help them out. It also helps if their friends and family think the robot is a good idea.
How to use in your project
- 1.Use the findings to justify design choices related to usability and functional demonstration in your design process.
- 2.Reference the study when discussing the importance of user acceptance factors in your research and development sections.

Paragraph starter
The adoption of assistive technologies by older adults is significantly influenced by perceived ease of use, perceived usefulness, and subjective norms, as demonstrated by research on soft service robots (Lee et al., 2020). Therefore, design efforts should prioritize intuitive interfaces and clear functional benefits, while also considering the social context surrounding the technology's use.
