Field: Human Factors
Source: Mathematical Problems in Engineering (2020)
Method: Comparative anthropometric survey and statistical analysis.
Sample: 1221 participants (921 Serbian, 300 Libyan)
Evidence: Strong effect

Significant variations in body dimensions between Serbian and Libyan male drivers require distinct interior space designs for optimal fit and comfort. This human factors research insight is drawn from a 2020 study published in Mathematical Problems in Engineering. Using Comparative anthropometric survey and statistical analysis. with 1221 participants (921 Serbian, 300 Libyan), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must move beyond generalized anthropometric data and incorporate specific regional user measurements to create more inclusive and ergonomic vehicle interiors.

Regional Anthropometric Differences Necessitate Tailored Vehicle Interior Dimensions

Significant variations in body dimensions between Serbian and Libyan male drivers require distinct interior space designs for optimal fit and comfort.

Mathematical Problems in Engineering · 2020

Key Findings

01Serbian male drivers exhibit a higher degree of correlation between anthropometric variables (67.85%) compared to Libyan male drivers (39.28%).
02Serbian male drivers are, on average, taller and have longer limbs and torsos than Libyan male drivers, with the exception of shoulder width.
03Consequently, optimal interior space dimensions differ, with Serbian drivers requiring approximately 1500 × 561 × 1230 mm and Libyan drivers needing 1400 × 591 × 1155 mm.

Application

Design takeaway

Designers must move beyond generalized anthropometric data and incorporate specific regional user measurements to create more inclusive and ergonomic vehicle interiors.

How to apply

When designing vehicle interiors for a global market, segment the target audience by region and research the specific anthropometric data for those regions to inform interior dimensions and component placement.

Project actions

01When selecting participants for your design project, consider the diversity of potential users.
02If your project involves physical products, research the anthropometric data relevant to your target user group's demographics.

Method & Evidence

AimTo collect and compare anthropometric data of Serbian and Libyan male passenger car drivers to inform vehicle interior design.

MethodComparative anthropometric survey and statistical analysis.

ProcedureAnthropometric measurements (standing height, sitting height, lower leg length, upper leg length, shoulder width, hip breadth, arm length, and foot length) were collected from 921 Serbian and 300 Libyan male drivers. Statistical analysis was performed to identify correlations within each group and compare mean values between the two groups, leading to the determination of distinct interior space dimensions.

Sample1221 participants (921 Serbian, 300 Libyan)

ContextAutomotive design, driver ergonomics.

Variables

IVNationality/Geographical region (Serbian vs. Libyan)

DVAnthropometric measurements (height, leg length, arm length, etc.), derived interior space dimensions.

CVGender (male), driver status (passenger car drivers).

Strengths & Limitations

Strengths

+Large sample size for Serbian drivers.
+Inclusion of a novel dataset for Libyan drivers.
+Direct comparison of derived interior space dimensions.

Limitations

The study focused only on male drivers and specific regions, so the findings might not apply to female drivers or other geographical areas.

Reliability & validity

The study's reliability is supported by a large sample size for one group and a systematic measurement procedure. Validity is enhanced by comparing mean values and derived dimensions, though generalizability might be limited by regional specificity and gender exclusion.

Think critically

How might cultural factors, beyond just genetics, influence anthropometric measurements and preferences for product design?

Design Principles

"Design for diversity: Anthropometric considerations must be geographically specific to ensure product suitability and user satisfaction."

Failing to account for regional anthropometric differences can lead to poorly fitting vehicle interiors, impacting driver comfort, usability, and potentially safety. Designers must recognize that a one-size-fits-all approach is inadequate when targeting diverse user populations.

What This Means for Your Design

People from different countries have different average body sizes. Car designers need to know these differences to make cars comfortable for everyone.

How to use in your project

1.Reference this study to justify the need for specific anthropometric data collection for your target user group, especially if they are from a distinct geographical or cultural background.
