Design takeaway

When designing AR experiences for learning or understanding complex objects, opt for 3D models to maximize user comprehension of spatial relationships.

How to apply

When developing AR training modules, product configurators, or assembly instructions, use 3D models to represent components and their spatial arrangements.

Project actions

  • 01When creating AR prototypes, consider the trade-offs between 2D and 3D representations for different learning objectives.
  • 02If your project involves teaching spatial concepts, explore how to integrate 3D modelling effectively within an AR framework.

Method & Evidence

AimTo investigate the impact of 2D versus 3D augmented reality (AR) visualizations on learning the spatial structure and relationships of components, and how individual spatial abilities moderate this effect.
MethodExperimental laboratory study
ProcedureParticipants were presented with either a 2D or 3D AR visualization of the human heart and instructed to identify specific components mentioned in an informational text. Learning outcomes, cognitive load, and the influence of spatial abilities were assessed.
Sample150 participants
ContextAugmented Reality (AR) learning environments, specifically for understanding spatial structures.

Variables

IVDimensionality of AR visualization (2D vs. 3D)
DVKnowledge about spatial relations of components, germane cognitive load, extraneous cognitive load, knowledge about spatial positions of components.
CVAR representation of the human heart, informational text, instructions given to participants.

Strengths & Limitations

Strengths

  • +Controlled experimental design comparing 2D and 3D AR.
  • +Inclusion of individual differences (spatial abilities) as a moderating factor.

Limitations

The complexity of creating high-fidelity 3D AR models can be a significant practical limitation. Performance issues with 3D models on certain devices might also affect the user experience.

Reliability & validity

The study employed an experimental design with controlled conditions, enhancing internal validity. Reliability of measures for cognitive load and knowledge acquisition would be key considerations for replication.

Think critically

While 3D AR visualizations are generally better for spatial learning, consider scenarios where 2D might be sufficient or even preferable (e.g., simpler objects, limited processing power, specific learning goals).

05

Design Principles

"Dimensionality in AR visualization significantly impacts the learning of spatial structures; 3D representations are generally superior for conveying spatial relationships."

This research highlights the critical role of dimensionality in AR for conveying spatial information. Designers creating AR learning experiences or product visualizations should prioritize 3D models to improve user comprehension of intricate structures and spatial arrangements.

06

What This Means for Your Design

When you use augmented reality to show someone how something is put together, using a 3D model is much better than a flat 2D picture for helping them understand where all the parts go and how they fit. This is especially true if the person is already good at imagining shapes and how they move in their head.
