1. The camera sees the player while the game adds scores and effects

- Show the required distance, frame boundaries and clear movement space.

- [Active Arcade](https://apps.apple.com/us/app/active-arcade/id1553158383?uo=4)

## How it works

The phone is installed so that the camera sees the necessary parts of the body. The player needs a visible and free area of ​​space. Posture assessments are approximate and do not replace diagnostics or professional assessment of exercise technique.

## Variants

### Variants and applications

<a id="family-body-variants"></a>

- The body is like a joystick. Action: Move the body relative to the calibrated center. Application: Runway control, flight, balancing arcade. Technologies: Recognition or machine learning model. <a id="variant-cam-097"></a>
- Repeat the pose. Action: Match the position of the main joints with the sample. Application: “Wall of poses”, dance movement training, living sculpture. Technologies: Recognition or machine learning model. <a id="variant-cam-098"></a>
- Squatting and standing up. Action: Cross calibrated pelvic and knee position thresholds. Application: Evasion, jump charge, motor mini-game. Technologies: Recognition or machine learning model. <a id="variant-cam-099"></a>
- Raising hands and steps. Action: Perform visible actions with the desired limb. Application: Rhythm game, warm-up, coordination tasks. Technologies: Recognition or machine learning model. <a id="variant-cam-100"></a>
- Angles and amplitude. Action: Achieve a given joint position range. Application: Motor puzzle, avatar size control, coordination training. Technologies: Recognition or machine learning model. <a id="variant-cam-101"></a>
- Counting repetitions. Action: Perform several completed pose cycles in the correct order. Application: Active tasks, combo series, motor counter. Technologies: Recognition or machine learning model. <a id="variant-cam-102"></a>
- Reproduction of movement. Action: Repeat a temporal sequence of poses taking into account the tempo. Application: Dancing, choreography, character imitation. Technologies: Recognition or machine learning model. <a id="variant-cam-103"></a>
- Retention and balance. Action: Maintain a pose within an acceptable range for a specified time. Application: “Freeze”, balancing game, world stability control. Technologies: Recognition or machine learning model. <a id="variant-cam-104"></a>
