The Shoka vehicle's interior design, particularly its seating angles, demonstrates suboptimal accommodation for the Iranian driver population, impacting comfort. This human factors research insight is drawn from a 2012 study published in Work. Using Descriptive-analytical study combining objective measurements and subjective user feedback. with 30 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Redesign seating angles and address occupant packaging to better fit the target demographic, and consider vibration reduction for improved driver comfort.
Driver seating angles in the Shoka vehicle require optimization for improved occupant accommodation.

Key Findings
- 01Occupant packaging variables and hand-arm angle showed the lowest accommodation percentage (53%).
- 02Seating angles exhibited moderate accommodation (73%).
- 03No significant differences in mental workload were observed across percentile groups.
- 04The average comfort discomfort rating was 3.9 during driving sessions, indicating a neutral state.
Application
Design takeaway
Redesign seating angles and address occupant packaging to better fit the target demographic, and consider vibration reduction for improved driver comfort.
How to apply
When designing vehicle interiors or workstations, conduct anthropometric surveys of the intended user base and perform ergonomic evaluations using both objective measurements and user comfort feedback during simulated or actual use.
Project actions
- 01When evaluating an existing product, clearly define the target user group and their relevant anthropometric data.
- 02Use a combination of objective measurements (e.g., reach distances, joint angles) and subjective feedback (e.g., comfort surveys, workload ratings) to assess ergonomics.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Combines objective and subjective evaluation methods.
- +Considers specific population percentiles for a more targeted assessment.
Limitations
The sample size might be small for broad generalizations. The study duration might not capture long-term comfort or fatigue effects.
Reliability & validity
The study's validity is supported by the use of established questionnaires and objective measurements. Reliability could be enhanced by increasing the sample size and conducting repeat measurements.
Think critically
How might the cultural context of driving in Iran (e.g., typical driving duration, road conditions) influence the interpretation of 'comfort discomfort' and 'mental workload' compared to other regions?
Design Principles
"Design for the target user's anthropometric and physiological characteristics to ensure optimal accommodation and comfort."
Understanding how vehicle interiors accommodate diverse user anthropometrics and physiological needs is crucial for designing safer, more comfortable, and less fatiguing driving experiences. This research highlights the importance of validating designs against specific population data rather than relying on generalized standards.
What This Means for Your Design
The car's seats and how drivers fit inside aren't perfectly designed for people in Iran, especially in terms of how their arms and legs fit. While it didn't make drivers more stressed, it wasn't super comfortable either. Adjusting the seat angles and reducing bumps could make it better.
How to use in your project
- 1.Reference this study when discussing the importance of anthropometric data in product design and the methods for evaluating ergonomic compatibility.
- 2.Use the findings on seating angles and occupant packaging as examples of common ergonomic issues in vehicle design.

Paragraph starter
This study by Mazloumi and Fallah (2012) investigated the ergonomic compatibility of the Shoka vehicle's interior with the Iranian population. Their findings indicated that occupant packaging and seating angles presented accommodation challenges, suggesting a need for design optimization to better suit user anthropometrics and enhance comfort during driving.
