A clean, simple, and tiny library to detect user input like Keyboard and Mouse.

Humans Meta Tech

You can track the activity of the user using mouse and keyboard activity. This will track the last activity of the mouse and keyboard since last used using timeframe.

First, you need to add a reference of the HmtInput.dll library to your project which is present in this location \bin\Debug\netstandard2.0\HmtInput.dll or you can install this package using Nuget Package Manager.

Then create a new class of your own and refer to different methods from the HmtInput.dll library.

using HmtInput;
using System;
using System.Windows.Forms;
public class User
{
    private System.Windows.Forms.Timer timer;
    private InputSources LastInput;

    public User()
    {
        LastInput = new InputSources();
        this.timer = new System.Windows.Forms.Timer();
        this.timer.Interval = new TimeSpan(0, 0, 0, 0, 100).Milliseconds;
        this.timer.Tick += timer_Tick;
        this.timer.Start();
    }

    private void timer_Tick(object sender, EventArgs e)
    {
        TimeSpan time = DateTime.Now.AddMinutes(1) - this.LastInput.GetLastInputTime();
        if (time.Minutes > 1)
        {
            this.timer.Stop();
            var result = MessageBox.Show("Are you Active?", "Checkpoint", MessageBoxButtions.YesNo, MessageBoxIcon.Question);
            if (result == DialogResult.No)
            {
                /* Do something big here */
                return;
            }
            this.timer.Start();
        }
    }
}

In the above code, an event timer_Tick is activated from the class constructor. Its interval is set to 0.1 Sec. This means the timer will check the mouse or keyboard activity after every 0.1 Sec.

You can set the duration in the if condition from 1 Min to any as you require.

After completing this code, create an object of this class like User in this example to the main form or anywhere else in your code to start tracking.

We hope this will be helpful to you.
