Sony mocopi 3D Mobile Motion Capture for VR & 3D Content Creation

Works great with the steam application. Somehow the tracking quality and stability is much higher than using the phone app. But honestly, it doesn't really worth $110 for just a receiver.

Do yourself a huge favor. Please take your money somewhere else I bought mocopi to use it for full body tracking in VR. I’m a dancer. I need stability, low latency, and freedom to export motion data. The tracking itself is decent. Not perfect, but potentially competitive. The problem isn’t the hardware. The problem is Sony. The mobile Mocopi Link app is practically unusable. It disconnects every few minutes. In longer sessions it simply isn’t reliable. I made the mistake of spending an additional ~$2,000 MXN (~$100 USD) on the sensor data receiver so I could use all 6 trackers without relying on my phone. I thought that would reduce friction. It made it worse. The official Steam VR app has been bugged for months. Tracking is locked at 30Hz. Thirty. In 2026. That makes the avatar look like it’s made of jelly. For dancing or fast movement, it’s unusable. The PC Microsoft Store version works much better… but it is artificially restricted. The free version only lets you “view” tracking. You can’t record mocap. You can’t export data to VR or into any file type You can’t stream to external software. To unlock basic functionality, you’re forced into a monthly subscription. And this is where it becomes absurd: To send motion data to open-source tools like SlimeVR — which are free and community-maintained — you have to pay Sony monthly just to unlock access to hardware you already purchased. The firmware is tightly locked down. There are no real plug-and-play alternatives unless you go through their subscription model. The sensor data receiver doesn’t fix anything because the bottleneck is the restricted software. No serious competitor forces you to pay a monthly fee just to use the hardware you already bought at its full potential. This is not a technical limitation. It’s a business decision. And it’s a terrible one. mocopi could have been a great tool. But the software implementation is restrictive, artificially limited, and clearly designed to extract recurring payments from users. The hardware is decent. The overall experience is an abuse of trust. Anything good this hardware could provide is immediately discarded by an absolutely predatory system which doesn’t respect its customers at all. I also have VIVE Ultimate trackers. Those suck because of the way they work hardware-wise. Mocopi just suck because Sony artificially makes them suck software-wise. i’m not subscribing to use the hardware. I’m selling these anywhere I can. I’m never buying anything from Sony ever again, I will tell my family and friends to do the same. And I hope you don’t ever buy anything from them again either. I regret not returning these when I could. Embarrassing, Sony. Simply utterly embarrassing.

La entrega fue de acuerdo a lo ofrecido. El equipo trabaja bien, solo tuve un poco de dificultad para conectar los sensores a mi celular, pero desconecté otros accesorios de bluethooth y me permitió la conexión. La aplicación registra el movimiento de acuerdo a lo que muestra en su página. Solo para aclarar no se registra movimientos a detalle de las manos pero en general si registra el movimiento y desplazamiento de cuerpo, lo recomiendo si no requieren registros más a detalle.

I use Mocopi for VRchat. It’s not great at what it does. And yes I did buy the USB puck so it’s not running off my phone. The software is kinda janky as you have to be in VR mode to pair them which means fumbling taking the headset on and off and then attaching them to your body. The tracking is not great. It drifts, it doesn’t match your exact pose, and it’s kinda cumbersome to attach six trackers just for a mediocre experience. If these were $100 and came with the usb Puck I would say they were worth it, but for the nearly $500 asking price these are bad. Switched to Pico 4 with Pico’s brand name trackers of which you only need 2 at minimum with an optional third for increased accuracy and they get the same job done better for a fraction of the price. Only downside to that is you have to import Pico products if you live in the US

It works with XYN motion studio for the mocopi pro system, but that's all it works with. I wish their SDK had support but no, Sony please add SDK support so I can use this with my own software made with game engines like Unity/Unreal. The latency with this is so good but locked behind a subscription service.

Tracking is pretty good for the price

Good

I sent them back in for a full return the setup isn't very easy and the quality of tracking isn't very high quality
