# GCDevicePhysicalInput

The common properties and methods for objects that represent the input profile of a device.

```
protocol GCDevicePhysicalInput : GCDevicePhysicalInputState
```

## Overview

You can safely call this protocol’s methods and access its properties from any thread, but not from multiple, concurrent threads.

## Topics

### Getting the device

[`device`](/documentation/GameController/GCDevicePhysicalInput/device)

The device that the physical input represents.

### Handling device input

[`nextInputState()`](/documentation/GameController/GCDevicePhysicalInput/nextInputState())

Returns the next input state from the queue.

[`inputStateAvailableHandler`](/documentation/GameController/GCDevicePhysicalInput/inputStateAvailableHandler)

The block that the profile calls when Game Controller adds an input state to the queue.

[`inputStateQueueDepth`](/documentation/GameController/GCDevicePhysicalInput/inputStateQueueDepth)

The maximum number of input values that the queue stores.

[`capture()`](/documentation/GameController/GCDevicePhysicalInput/capture())

Returns a snapshot of the physical device inputs.

[`elementValueDidChangeHandler`](/documentation/GameController/GCDevicePhysicalInput/elementValueDidChangeHandler)

A block that the profile calls when an element’s value changes.

### Changing the callback dispatch queue

[`queue`](/documentation/GameController/GCDevicePhysicalInput/queue)

The dispatch queue that the system uses for callbacks.
