### Example

The example shows how to detect hands with the `StreamSourceExtensions` class.

#### Detect hands in StreamSource

First, create a [StreamSource](https://handtracking.lightbuzz.com/ui-reference/streamsource) component and a [Handtracker](https://handtracking.lightbuzz.com/api-reference/handtracker) object.

```csharp
[SerializeField] private StreamSource _source;
private readonly HandTracker handTracker = new HandTracker();
```

Then,  use the `HandTrackerExtensions` class to detect hands in the specified [StreamSource](https://handtracking.lightbuzz.com/ui-reference/streamsource).

```csharp
List<Hand> hands = _handTracker.Load(_source);
```
