Connecting golf practice to life beyond XR

Bollo is an XR exercise concept for adults in their late 50s to mid-60s. Over nine months, I worked with one other designer on research and UX systems, and led the 3D UI and spatial interactions.

The Problem

Participants described uncertainty about their changing bodies and a disconnect between exercise platforms and daily life.

the question

How might XR help people adapt exercise to their changing bodies and carry its value into daily life?

our answer

We developed Bollo through a concept video and selected AR and camera-based prototypes, pairing body-specific practice with ways to use exercise data in daily life.

Finding

Body

Physical changes increased their need to understand their bodies.

“My body doesn’t move like it used to, so I check my posture more often.”

Life

They wanted to shape their days around what mattered to them.

“[…] my days depend more on what I choose to fill them with.”

Value beyond exercise

Argument 1 / Feedback design

We framed physical change as adaptation and growth.

We paired body-specific guidance with a flower metaphor that acknowledges users’ efforts to adjust their movements.

Camera prototype

Participants connected the highlighted areas to their own discomfort.

Participants reacted positively to seeing their posture analyzed and mentioned discomfort in areas indicated by the prototype.

Argument 2 / Data-use design

We connected exercise data to daily life to give users a reason to return.

We proposed using exercise and body data for choices beyond practice, from personalized equipment to sharing information with healthcare providers.

Spatial interaction / Club selection

I brought selection controls forward so the task stayed in focus.

I reworked the club-selection space when a shop-like environment overshadowed the selection task.

Concept feedback

Viewers expressed interest in using the concept and responded positively to the proposed hospital connection.

LESSON I LEARNED

Learning what makes an XR coach worth returning to

Value extends beyond the session

I learned to consider what makes an experience worth returning to. For Bollo, this meant extending the value of exercise data into everyday decisions, from choosing suitable products to communicating with healthcare professionals. This shifted my focus from designing a training session to supporting an ongoing relationship with one’s body.

An AI coach needs more than a personality

Designing Marimo taught me to connect character design with interaction logic: when the coach appears, how it speaks, and what data informs its guidance. Considering available tracking technologies alongside these decisions helped me think more concretely about how the coaching experience could work.

Concept feedback is only a starting point

The exhibition helped me understand how people perceived Bollo, but videos and prototypes offered limited insight into actual use. I learned to distinguish feedback on the concept from evidence about usability. My next step would be to test whether users can understand and act on the feedback while swinging.
