Blink rate per min

[Asish]

Dear All,

Is there any standard way to calculate the number of blinks per min from eye openness data?

 

Thanks in advance

Hello  @Corvus  @VibrantNebula  @Hank_Li

Would you please let me know how to calculate the number of blinks per min from eye openness data? Any standard way to get it correctly?

 

Thanks

Hi Asish,
We did not provide such API for calculating the number of blinks per minute.
Maybe you can calculate it according to the value of this blendshape (blinks)

 

Thanks

@Asish Here is Unity sample code to check for blinking. You can adjust the blinkLimit if desired (0 fully closed, 1 fully open).

    private static float blinkLimit = 0.1f;
    private static float leftOpen, rightOpen;

    public static bool IsBlinking()
    {
        // check both eyes open
        if (IsWinkingLeft() && IsWinkingRight())
            return true;
        else
            return false;
    }

    public static bool IsWinkingLeft()
    {
        SRanipal_Eye.GetEyeOpenness(EyeIndex.LEFT, out leftOpen);

        if (leftOpen < blinkLimit)
            return true;
        else
            return false;
    }

    public static bool IsWinkingRight()
    {
        SRanipal_Eye.GetEyeOpenness(EyeIndex.RIGHT, out rightOpen);

        if (rightOpen < blinkLimit)
            return true;
        else
            return false;
    }
