Key Findings
- 01A scene taxonomy can be developed by considering visual structure and task within a virtual environment.
- 02Applying the taxonomy to accessibility issues like limited head mobility can lead to the generation of novel viewing techniques.
- 03Users perceive tradeoffs between accessibility, realism, and spatial awareness when evaluating new VR viewing techniques.
Application
Design takeaway
When designing virtual environments, use a structured taxonomy to analyze viewing techniques and proactively address accessibility needs, understanding that users will balance usability with other factors.
How to apply
When designing a VR experience, first categorize the types of scene viewing required based on the environment's structure and the user's tasks. Then, use this classification to select or develop viewing techniques that best meet the needs of your target audience, including those with potential mobility constraints.
Project actions
- 01When researching existing solutions for your design problem, try to categorize them based on their underlying principles or functionalities.
- 02Consider how your design choices might impact different user groups, especially those with specific accessibility requirements.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Systematic approach to identifying design problems and generating solutions.
- +Focus on a specific accessibility challenge within a relevant technological domain.
Limitations
It can be challenging to create a truly comprehensive taxonomy that covers all possible scenarios and user needs. Evaluating new techniques with a small sample size might not capture the full range of user experiences.
Reliability & validity
Reliability could be improved by using more objective measures of spatial awareness and task performance. Validity is supported by the systematic approach to taxonomy development and the focus on user-reported tradeoffs.
Think critically
To what extent does a predefined taxonomy limit or enhance creativity when designing novel interaction techniques?
Design Principles
"Systematic classification of interaction techniques is crucial for identifying design opportunities and addressing user needs, especially in novel technological domains."
This research provides a framework for designers to analyze and create virtual environment interactions. By categorizing viewing techniques, it enables more informed decisions, particularly when designing for users with physical limitations, ensuring broader usability and inclusivity.
What This Means for Your Design
Researchers made a list (taxonomy) of ways people look around in virtual reality. They used this list to create new ways for people who can't move their heads much to see virtual worlds. People liked the new ways but also noticed they weren't as realistic or didn't help them understand space as well.
How to use in your project
- 1.Use the concept of developing a taxonomy to structure your research into existing products or solutions, helping to identify design gaps.
- 2.When evaluating your own design, consider how it addresses specific user needs and what tradeoffs might be involved.

Paragraph starter
The development of a structured taxonomy, as demonstrated in the study by Franz et al. (2023), provides a valuable methodology for analyzing and innovating within design domains. By categorizing existing scene-viewing techniques in virtual environments based on visual structure and task, the research enabled the systematic generation of novel solutions for users with limited head mobility. This approach highlights the importance of a systematic, research-informed framework for identifying design opportunities and addressing specific user needs, particularly in emerging technologies.
