Ergonomics Is Not Just About "Comfortable Grip" - It Involves Verifiable Metrics Like Size, Center of Gravity, Pressure, and Usage Posture.

Common Evaluation Points

Grip Diameter and Anti-Slip, Button Travel and Feedback, Screen/Indicator Readability, One-Handed Operation Limits.

Long-term Use Fatigue Points: Weight Distribution, Edge Chamfering, Cable/Port Placement.

How to Verify

Use Target User Hand Size Range for Sizing, Not Just Designer Feel.

Perform real task testing (unboxing, installation, cleaning, storage) during the prototype stage.

Smart Practices of YouTai

Clarify usage scenarios and user groups at project initiation, and set measurable human-machine goals.

Confirm critical tactile decisions with signatures on prototypes to avoid production disputes.
