Camera Motion Tennis Game
Hit forehands, backhands, and smash overhead volleys against a rapid-fire virtual tennis ball machine.

Play Grand Slam Tennis with body movement
Grand Slam Tennis is a sports game in the VXROOM camera motion library. The game uses body movement as input, so you can play in a modern browser without a handheld game controller. Set up the camera so your full body is visible, leave enough clear space to move, and follow the actions shown on screen.
A typical session lasts 5 min. The listed difficulty is hard, and an average session is estimated at 36 kcal. Calorie use varies with session intensity, body size, and movement range, so this number is a general gameplay estimate rather than a medical measurement.
Movements and gameplay
- Topspin Forehand: Step in with shoulder rotation and sweep your arm low to high.
- Backhand Drive: Turn your opposite shoulder toward the camera and drive through the stroke.
- Overhead Smash: Reach high above your head to crush lob balls into the court corners.
VXROOM turns recognized movement into game actions. Begin with controlled movements while learning the timing. Increase your range and pace after you understand the prompts and can keep a clear area around you.
What you need
Use a phone, tablet, or computer with a camera and a supported web browser. Bright, even lighting and a stable camera position help the game see your movement. Clothing that contrasts with the background can also make your outline easier to detect. No VR headset is required.
