UFOs in thequiet forest.

A redesign of the IoT sensors (Oplate 小黑盤) pairing screen used by elderly care center staff — replacing technical setup with a small, friendly narrative so non-technical caregivers can connect motion sensors to the smart TV without help, anxiety, or training.

The problem

Four small frictions,

one delayed activity.

Observing staff use the original interface, four pain points kept showing up. Individually small. Together, enough to make caregivers ask a colleague for help — delaying the actual game session for the elderly.

02 / Silence

No feedback during pairing

Two empty boxes gave no visual sense of progress. Staff tapped repeatedly, unsure if anything was happening.

03 / Atmosphere

A clinical, alarming red

The screen looked like an error message. For a tool used in a warm, social environment, the tone was wrong.

04 / Confidence

Fear of breaking it

Without playful affordance, every tap felt high-stakes. Staff hesitated; residents waited.

01 / Jargon

Words made for engineers

"Scanned", "Connected", "Refresh" — system states, not human actions. Staff weren't sure which side meant what.

Who it's for

Designing for thecaregiver,

not the engineer.

The end audience of the gaming system is seniors — but the people touching this

screen, every day, are care center staff. Their context shaped every decision.

The concept

The IoT sensors already felt like tiny UFOs, their LED rings scanning for connection.

So the UI embraced the metaphor: moonlit skies, floating saucers, and pairing reimagined as welcoming visitors.

Clear Chinese instructions replaced technical system states with a single, obvious next step.

The interface just hadn't noticed yet.

OUTCOME

From a chore to a20 second story.

The redesigned flow let care staff complete pairing without training, without asking colleagues, and — by their own report — without dreading it.

More importantly, the warmth of the setup screen carried into the activity itself.

The first thing residents saw on the TV was no longer a configuration menu; it was a forest under a quiet sky.
