When 3D models are designed with clear visual cues and intuitive interaction logic, they can enhance perceived usability by making spatial or complex information more tangible and easier to understand.
They bridge abstract concepts with visual intuition, allowing users to grasp relationships (e.g., product structure, spatial layout) faster than 2D representations. This reduces cognitive effort, as users spend less time interpreting information, directly boosting the sense of ease of use.
To maximize this effect, prioritize simplicity in 3D model design: avoid cluttered details that distract. Focusing on core functions helps users quickly engage with key features, reinforcing a positive perception of usability.
