Project Title

🎯 Challenge

As VR fitness apps grow in popularity, many users and developers assume that virtual walking can match real-life exercise in terms of physical benefit. But are those assumptions accurate? This study set out to answer that question from both a physiological and user experience perspective.

 

🧩 UX Design Process

​

1. Empathize

We sought to understand the real-world needs of four core groups:

• VR users who want engaging but effective fitness alternatives

• Trainers and clinicians considering VR in rehab or training

• Health tech developers aiming to build more immersive VR tools

• Researchers investigating the human body’s response to virtual environments

By identifying these user personas, we recognized the importance of validating physical realism in VR to create trustworthy, motivating digital experiences.

 

2. Define

Research Goal:
To evaluate whether walking in VR provides the same physiological benefits as outdoor walking. ​

 

Problem Statement:
"Users need evidence that VR exercise is physically effective to trust and adopt it as a valid fitness tool."

 

3. Ideate

-We designed a research framework that would simulate a realistic walking experience in both virtual and physical environments while tracking physiological responses.

-We also considered potential friction points like motion sickness, unfamiliarity with VR, and hardware setup challenges to account for UX beyond just physiological data.

 

4. Prototype

Although this was a physiological study, we treated the VR walking environment as a testable prototype.

The design choices in the VR prototype aimed to simulate real-world walking as closely as possible—minimizing visual-lag, maintaining pace synchronization, and offering environmental visuals for immersion.

Research Methodologies

As lead researcher, I developed a mixed-method approach to capture both quantitative and qualitative perspectives.

🧪 Lab-Based Physiological Testing

💬 Observational Interviews

📈 Statistical Analysis

 

Surveys Pre & Post Test

Following each walk, participants were informally debriefed to share how the walk felt, their level of comfort, motivation, and immersion. Example questions are shown below:

Insights

✅ Equivalency in Energy Output

There were no statistically significant differences in calories burned per minute between the two conditions. VR and outdoor walking offered comparable physical exertion.

🧠 Substrate Utilization Mirrored Reality

The proportion of fat vs. carbohydrate usage was consistent between virtual and real walks. From a metabolic standpoint, the body responds to both similarly.

🧍🏽‍♀️ Behavioral Observations

Participants noted slightly altered postures in VR but adjusted quickly. Most reported feeling immersed, but some missed sensory inputs like breeze, incline, and terrain — revealing areas where sensory realism in VR could improve.

Concept & Application

These findings provide evidence that VR walking can replicate the physiological impact of outdoor walking, which can empower design teams to:

• Create trustworthy fitness metrics in VR

• Build real-time biofeedback UIs aligned with users' physical responses

• Design more emotionally engaging fitness environments that users are motivated to return to

​

Final Reflection

This study helped bridge the gap between physiology and UX, showing how product teams can leverage evidence-based insights to design VR fitness tools that are both credible and motivating. As VR expands into wellness, the intersection of human-centered research and biomechanical data will be key to user trust and long-term engagement.
