nperceptual's Introduction

nperceptual

Finger points and gesture recognition library for Microsoft .NET Framework using Intel Perceptual SDK.

Dependencies (Managed via NuGet)

log4net

Usage

The main entry point of the library is the PerceptualManager class.

Sample code to display "perceptual cursor" using any WPF Shape/Component, with hand open-close ("grab") gesture detection, and Button.ClickEvent simulation.

private readonly PerceptualManager perceptualMgr;
private readonly PerceptualAdapter perceptualAdapter;

public MainWindow()
{
    InitializeComponent();
    perceptualMgr = new PerceptualManager();
    perceptualAdapter = new PerceptualAdapter(perceptualMgr, this);
    InitPerceptual();
}

private void InitPerceptual()
{
    perceptualMgr.Init();
    perceptualMgr.Start();
    perceptualAdapter.ExcludedControls.Add(hand);
    perceptualAdapter.Move = Perceptual_Move;
    perceptualAdapter.Close = Perceptual_Close;
    perceptualAdapter.Open = Perceptual_Open;
}

private void Perceptual_Open(object sender, RoutedEventArgs e)
{
    if (sender == this)
    {
        hand.Fill = new SolidColorBrush(Color.FromRgb(0x90, 0x90, 0x90));
    }
}

private void Perceptual_Close(object sender, RoutedEventArgs e)
{
    if (sender == this)
    {
        hand.Fill = new SolidColorBrush(Color.FromRgb(0xff, 0x33, 0));
    }
}

private void Perceptual_Move(object sender, HandMoveEventArgs e)
{
    if (sender == this)
    {
        hand.Margin = new Thickness(
            (-hand.ActualWidth / 2) + e.Location.X,
            (-hand.ActualHeight / 2) + e.Location.Y,
            0, 0);
    }
}

private void Window_Unloaded(object sender, RoutedEventArgs e)
{
    perceptualMgr.Dispose();
}

private void Window_Closed(object sender, EventArgs e)
{
    perceptualMgr.Dispose();
}
