How to Play PC Games Without a Controller
Controllers are great — until they're not. Maybe your wrist is tired, maybe you want a workout with your gaming, maybe a kid in your house can't work twelve buttons, or maybe you just want to feel like you're swinging that racket. Here's the state of playing PC games with your body instead of a controller, in 2026.
Option 1: Webcam pose tracking (free, limited)
Browser platforms like MovePlay and university projects like MotionInput use your existing webcam to track gestures and play simple web games. Great for a taste of motion gaming — but they only run their own mini-game libraries. You can't point your webcam at your existing Steam library and start playing.
Option 2: Wearable motion trackers (accurate, fiddly)
IMU trackers such as SlimeVR, Sony mocopi and HaritoraX strap sensors to your body and drive your avatar in VR apps and VTubing setups. They're excellent at that job — but they don't emit standard game inputs, so they can't control a regular PC game. And suit-up time is real: charging and strapping 6–10 sensors every session.
Option 3: Camera-based body control (the new category)
The missing piece has been a device that does what the Kinect promised: watch your real body with a camera — and translate that movement into standard mouse, keyboard and gamepad inputs that any PC game already understands.
That's exactly what Plaik does:
- AI pose estimation tracks 33 body landmarks in real time, on-device.
- Control profiles map gestures to inputs — punch → button press, hand position → mouse movement, body lean → joystick axis.
- Nothing to wear — step in front of the camera and play.

Which games shine with body control?
- Sports & boxing — swinging a real racket or throwing real punches is the most natural mapping that exists.
- Racing — leaning like a steering wheel beats analog-stick precision for feel.
- Fitness & exergaming — squats and dodges as game inputs turn workouts into play.
- Party & family games — anyone can move their body; not everyone can work a gamepad.
- FPS — pointing your hand to aim feels like the future, with practice.

What about the Kinect?
Kinect proved the demand — 24 million units sold — but tied motion gaming to a shrinking library of Kinect-only titles, and Microsoft discontinued the hardware in 2017. The category is being rebuilt around open PC input. We compare them directly in Plaik vs Kinect.
The takeaway
Controller-free PC gaming used to be a choice between mini-game websites and wearable sensor suits. Camera-based body control with real input mapping is the third option — and it's arriving as a small camera, one cable, and the games you already own.
