Turning Treadmills into Play: How Lincing Roaming Markets Home Fitness via HarmonyOS

The Problem with the Treadmill in the Corner

Every home has one. A treadmill that was bought with good intentions, used for a week, and now serves as a rack for jackets. The problem isn't that people don't want to exercise; it's that the exercise itself is boring. Running in place, staring at a wall, waiting for it to be over—that's not a compelling pitch.

Lincing Roaming, a new fitness app for Huawei's Vision series, thinks it has a better answer. Instead of just putting a screen in front of a treadmill, they've built a system where your steps control the game. You walk, run, dodge, and interact with scenes on the big screen. The pitch isn't 'exercise more'; it's 'come play for a few minutes.'

From Chore to Play: The Core Idea

The product lead, Zhou Jing, puts it simply: 'We want to turn “I have to exercise” into “I want to play.”' That means the device isn't a treadmill in the traditional sense. It's more like an elliptical or a glider, moving at speeds from 1 to 6, designed for light movement.

The key is the content. Users can walk through 4K filmed scenic trails, where the view moves as you step, complete with ambient sounds. Or they can jump into a 3D game like 'Myth Adventure,' where they dodge obstacles, collect items, and gesture to interact with characters. The device is about 1.2 meters wide, giving enough room for side-to-side movement, making the game feel more real.

This isn't about making people run faster. It's about getting them to start. And once they start, the hope is they'll stick with it.

Pivoting to Family: Not Just for Fitness Buffs

Initially, Lincing Roaming targeted office workers and fitness novices—people who want to exercise but lack the discipline. But during testing at HDC 2026, they noticed something surprising: kids loved it. They'd line up to play the games, sometimes multiple times. Older users cared less about the games and more about the safety, cushioning, and stability of the machine.

That feedback shifted the positioning. This isn't just a fitness tool; it's a family activity. Kids want to play, adults want to move, and grandparents want something gentle. The device had to be accessible to all.

Why HarmonyOS? An Ecosystem Bet

Choosing to build on HarmonyOS wasn't an easy call. The team knew they were betting on a relatively young ecosystem. They looked at other TV platforms and found them fragmented: different brands had different capabilities, some had cameras, some didn't. That fragmentation is a nightmare for an app that needs consistent performance for real-time interaction.

Huawei's approach stood out. It's not just about the TV; it's about connecting the TV, the phone, wearables, and other devices into one ecosystem. For Lincing Roaming, that's crucial. The device needs to talk to the screen, and eventually, it should talk to your health data too.

The team had heated debates about this. Diving deep into HarmonyOS meant not spreading their efforts across other TV platforms. But they saw the potential in the ecosystem's integration and distributed capabilities.

Making It Feel Natural: The Hidden Tech

The magic is in the details. Getting the experience to feel 'natural' is a technical challenge. The first hurdle was gesture recognition. Early HarmonyOS SDKs only offered 2D skeletal tracking, which is less accurate than the 3D versions they were used to on other platforms. At busy events like HDC, this could be a problem—the system might mistake a bystander's movement for yours. Huawei later introduced a locking mechanism that focuses on the primary user, which helped a lot.

Performance was another issue. Some older Vision TVs couldn't handle the 3D models, so the team had to compress assets and optimize relentlessly. Then there was latency. Initial Bluetooth connections had noticeable delays. Switching to Huawei's NearLink (SparkLink) reduced lag to nearly imperceptible levels—critical for that 'follow-your-foot' feel.

What Users Want Next: Connectivity and Social Features

At HDC, two questions kept coming up. The first: 'How is this different from a treadmill?' The second: 'Can I play online with friends?' That second one is telling. People want exercise to be social, even at home.

The team is listening. They're planning online modes, companion features, and better onboarding guides. They're also working on integrating with Huawei Health, so the device can recommend specific trails or intensities based on your history and physical condition. Imagine stepping on, and the screen says, 'Grandpa, today we'll take a gentle forest walk for 15 minutes.' Or, 'Hey kid, you're full of energy—let's do a fast-paced challenge.'

The Bottom Line: A Different Kind of Fitness Ad

So, how is this different from a treadmill? It's not about the hardware. It's about the relationship. A treadmill is a piece of exercise equipment. Lincing Roaming wants to be a family entertainment center that happens to get you moving. It's a smart positioning for the home market, where the biggest enemy is boredom.

For advertisers and marketers, this case study is a reminder: the product is the message. The best ad for a fitness device isn't a 30-second spot showing sweaty models; it's a child laughing while dodging virtual obstacles, or a grandparent taking a peaceful walk through the Alps. That's the story that sells. And it's why Lincing Roaming is betting on HarmonyOS—not as a distribution channel, but as part of the product experience itself.

The journey isn't over. The app is live on Huawei Vision, but the team knows they need to keep iterating. The goal is to make people want to step on, day after day, not because they have to, but because it's fun. That's the kind of habit that builds a brand.
