Sample: 15 participants
Evidence: Strong effect

Designers should focus on comfort and unhindered movement in passive exoskeletons, as these factors are stronger predictors of user adoption than the degree of physical exertion reduction. This human factors research insight is drawn from a 2026 study published in Safety Science. Using Comparative field study with 15 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing assistive wearable devices, focus on integrating seamlessly with natural human movement and ensuring a high level of user comfort, as these aspects are paramount for user acceptance and sustained use.

Soft exoskeletons enhance worker adoption by prioritizing comfort and movement over maximal support

Designers should focus on comfort and unhindered movement in passive exoskeletons, as these factors are stronger predictors of user adoption than the degree of physical exertion reduction.

Safety Science · 2026

Key Findings

01Soft exoskeletons significantly reduced perceived fatigue and exertion more than rigid designs.
02Comfort and usability were stronger predictors of willingness to adopt exoskeletons than physical benefits alone.
03Movement hindrance was the strongest factor correlating with the rejection of exoskeleton adoption.

Application

Design takeaway

How to apply

When developing wearable assistive devices, conduct user testing in realistic work environments, focusing on subjective feedback regarding comfort and movement alongside objective performance metrics.

Project actions

01When designing a wearable product, consider how it will feel and move with the user during their typical activities.
02Gather qualitative feedback on comfort and usability alongside quantitative performance data.

Method & Evidence

AimTo compare the effectiveness of rigid versus soft passive back-support exoskeletons on perceived physical exertion, comfort, and adoption among masonry workers in a field setting.

MethodComparative field study

ProcedureFifteen masonry workers tested two types of back-support exoskeletons (one rigid, one soft) over two days in their typical work environment. Data on perceived physical exertion, comfort, and willingness to continue using the devices were collected through structured interviews and compared to baseline conditions.

Sample15 participants

ContextConstruction industry (masonry tasks)

Variables

IV["Type of exoskeleton (rigid vs. soft)"]

DV["Perceived physical exertion","Perceived fatigue","Comfort","Adjustability","Movement hindrance","Willingness to continue use"]

CV["Participant occupation (masonry worker)","Work environment (on-site)","Tasks performed","Duration of testing"]

Strengths & Limitations

Strengths

+Field-based study conducted in a realistic work environment.
+Direct comparison between two distinct exoskeleton designs.

Limitations

The study was conducted with a small group of workers in a specific industry, so the findings might not apply to all professions or types of exoskeletons.

Reliability & validity

The study's validity is enhanced by its field-based methodology, simulating real-world conditions. Reliability could be improved by increasing the sample size and duration of testing to account for individual variations and adaptation over time.

Think critically

How might the long-term effects of using a less supportive but more comfortable exoskeleton compare to a more supportive but less comfortable one in terms of injury prevention?

Design Principles

"Prioritize user comfort and freedom of movement in wearable assistive device design to maximize adoption and effectiveness."

In the development of assistive wearable technologies, such as exoskeletons, understanding the nuanced factors influencing user acceptance is critical for successful implementation. Prioritizing comfort and freedom of movement can lead to higher adoption rates and more effective long-term use, ultimately achieving the intended benefits of reducing strain and preventing injuries.

What This Means for Your Design

For wearable helpers like exoskeletons, making them comfy and easy to move in is more important for people actually using them than just how much they help lift things.

Paragraph starter

Research indicates that for wearable assistive devices, user adoption is significantly influenced by comfort and the degree to which movement is unhindered, often more so than the direct physical benefits provided. For instance, a study comparing rigid and soft exoskeletons for masonry workers found that the soft design, which offered greater comfort and less movement restriction, led to higher willingness to use the device, despite potentially offering marginally less peak support than a rigid alternative. This highlights the critical need for designers to prioritize user experience factors like ergonomics and freedom of motion to ensure the practical success of their innovations.
