Gesture Recognition

info

The following Dollars MoCap products support sending gesture events to Unity,

  • Dollars SOMA

Listening for Gesture Events​

You can react to body postures and hand gestures by listening to the Dollars.GestureListener.OnGestureDetected and Dollars.GestureListener.OnHandGestureDetected events.

A typical controller class would look like this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GestureController : MonoBehaviour
{
    void Awake()
    {
        Dollars.GestureListener.OnGestureDetected += HandleGesture;
        Dollars.GestureListener.OnHandGestureDetected += HandleHandGesture;
    }

    void HandleHandGesture(string gesture)
    {
        Debug.Log(gesture);
    }

    void HandleGesture(string gesture, float value)
    {
    }
}

Event Parameter Description​

In these two events:

  • The gesture parameter indicates the name of the captured body or hand gesture.
  • For ZoomIn and ZoomOut gesture, the value parameter represents the ratio of the current distance between hands to the distance when the action was triggered.
  • For other gestures, this value is always 0.

Sample Project​

You can find an example here of controlling the camera FOV using ZoomIn and ZoomOut, as well as switching effects through gestures and body postures.
