Understanding how tools are used involves distinct but interconnected brain regions processing both the object's function (semantic knowledge) and its physical interaction capabilities (mechanical knowledge). This human factors research insight is drawn from a 2023 study published in Communications Biology. Using Functional magnetic resonance imaging (fmri) study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must consider the dual nature of tool understanding – semantic and mechanical – to create products that are both intuitively understood and physically effective.

Key Findings
- 01Both semantic and mechanical understanding of tools activate dorsal and ventro-dorsal brain regions.
- 02Semantic understanding specifically recruits medial and posterior temporal areas.
- 03Mechanical understanding engages inferior parietal and posterior temporal regions.
- 04Distinguishing between action-consistent and action-inconsistent tool pairs activates a broad frontotemporal neural circuit.
- 05The left inferior parietal and anterior temporal lobes act as hubs for integrating physical and conceptual knowledge about tools.
Application
Design takeaway
Designers must consider the dual nature of tool understanding – semantic and mechanical – to create products that are both intuitively understood and physically effective.
How to apply
When designing a new tool or improving an existing one, consider how its visual form (semantic) and its physical interaction (mechanical) work together to convey its purpose and usability.
Project actions
- 01When designing a tool, think about both how it looks and what it does (semantic) and how it feels and moves in your hand (mechanical).
- 02Consider how to make the visual cues of your design clearly suggest its function.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses advanced neuroimaging techniques (fMRI) to provide objective data on brain function.
- +Differentiates between semantic and mechanical aspects of tool understanding.
Limitations
This study used brain imaging, which is complex. Your own design project might not have access to such advanced methods, so you'll need to infer user understanding through observation and feedback.
Reliability & validity
fMRI studies typically have good internal validity due to controlled experimental conditions. Reliability can be a concern due to variability in individual brain responses, often addressed by larger sample sizes and statistical analysis.
Think critically
How might the cultural context or prior experience of a user influence the balance between semantic and mechanical processing when understanding a new tool?
Design Principles
"Integrate semantic and mechanical affordances in tool design to optimize user comprehension and interaction."
This research highlights that effective tool design and interaction require consideration of both the conceptual understanding of a tool's purpose and its practical, physical usability. Designers can leverage this by ensuring that the form and function of a tool intuitively communicate its intended use and are physically intuitive to manipulate.
What This Means for Your Design
Your brain uses different parts to figure out what a tool is for and how to use it physically, and these parts work together.
How to use in your project

Paragraph starter
Research indicates that understanding tool-related actions involves the integration of semantic and mechanical knowledge, processed by distinct yet interconnected brain networks. This suggests that effective design should not only convey a tool's purpose visually but also ensure its physical form and interaction methods are intuitive and align with users' mechanical understanding.
