Full body tracking may arrive on Steam Frame via new standalone tracker

What the new tracker promises

Soulart, a company known for innovative motion capture hardware, announced a prototype that could enable full body tracking on the Steam Frame console. The device works independently of a headset, meaning users could experience full body immersion even when the console is used in a living‑room setup.

How the device works without a headset

The tracker resembles a compact base station and uses infrared LEDs combined with computer vision algorithms to map a player’s movements. By placing a few sensors around the play area, the system creates a 3‑dimensional map of the space and tracks the position of body‑mounted markers.

Key technical components

• Infrared emitter array for low‑light operation
• High‑speed camera that captures marker positions at 120 frames per second
• On‑board processor that runs pose estimation software
• Wireless link that streams data to the Steam Frame via Wi‑Fi

Because the tracker does not rely on the headset’s cameras, it can be used with any display configuration, including TV or monitor setups.

Potential impact on VR experiences

Full body tracking expands the range of interaction beyond hand controllers. Players could swing their arms, duck, or even perform dance moves that are reflected in the virtual world. This opens up new game genres such as fitness, rhythm, and social VR where body language is essential.

Benefits for developers

1. Access to richer motion data without redesigning headset firmware
2. Ability to support multiple players in the same space using a single console
3. Reduced hardware cost for consumers who already own a Steam Frame

Game studios can integrate the tracker through the existing SteamVR Input system, which already supports custom devices. This means that developers will not need to rewrite large portions of their code.

Comparison with existing tracking solutions

Current full body solutions, such as the HTC Vive Trackers, require a base station that is tied to a VR headset. They also need multiple trackers attached to the feet, waist, and other points. Soulart’s approach reduces the number of external components to a single unit that covers the whole play area.

Another alternative is the use of external cameras like the Microsoft Kinect, which can capture full body motion but lacks the low latency required for competitive gaming. The new tracker aims to combine the accuracy of dedicated hardware with the convenience of a single device.

Challenges and next steps

While the prototype shows promise, several hurdles remain before it reaches consumers.

Technical hurdles

• Ensuring consistent tracking in brightly lit rooms where infrared can be washed out
• Minimising latency to stay below the 20‑millisecond threshold that most VR developers consider acceptable
• Providing robust firmware updates that can be delivered over the internet

Market considerations

Pricing will be a key factor. If the device can be sold for under $150, it could become a standard accessory for Steam Frame owners. Partnerships with game publishers could also drive adoption, especially if titles are released that showcase the full body capabilities.

Steam Frame itself is designed as a console‑style VR system that plugs directly into a TV. Adding full body tracking could differentiate it from competitors like the PlayStation VR2, which relies on handheld controllers for most interactions.

Industry response and expert opinions

Tech publications have taken note of Soulart’s announcement. The Verge highlighted the potential for a more social VR experience, while a research paper from MIT Media Lab discussed the importance of low‑latency body tracking for immersion.

Valve’s own documentation on SteamVR integration confirms that third‑party trackers can be recognized without firmware changes, which bodes well for Soulart’s plan.

What this means for Steam Frame owners

Current Steam Frame users can expect a future upgrade path that does not require buying a new headset. When the tracker becomes available, owners will likely need to install a small software update and place the unit in a corner of the room. After calibration, the system should recognize full body movements automatically.

For new buyers, the combination of a console‑style VR device and a standalone tracker could represent a complete, out‑of‑the‑box solution for immersive gaming.

As the VR market continues to grow, innovations like this tracker illustrate how hardware developers are looking beyond the traditional headset‑centric model. By separating motion capture from the headset, developers can create more flexible setups that fit a wider range of living spaces.
