Kinect Status Notifier – Notify Kinect Status in System Tray

The Kinect Status Notifier, will pops up a notification in system tray whenever this changes in sensor status.   This can be very useful for Kinect for windows SDK based application.

To understand the flow of the Kinect status and the scenarios on which it can occur in a simpler way, refer the diagram below. Once the device is plugged in and power is turned off it will goes to “Not Powered” state, similarly for unplugging the device from USB port will returns the “Disconnected” status. If you plugged it in back or turn the power on, first it will in “Initializing” state before turns into “Connected” state.

Home Security System Using Kinect, Azure, Windows Phone and Windows 8

Most the people who were in the TechEd 2012 India would have witnessed the cool demo by me and Jebarson made on the opening Keynotes of the event.  And now we would like to share how this solution was developed so that you can also build your own.

Background

Before we could pitch in, let me give a little background on how we decided to build this on our garage. Developer Conference 2011 on Hyderabad was scheduled on October 2011 and myself and Jebarson were looking forward to show something cool on our own interested areas. Jebarson was looking out for something on Windows Azure and Windows Phone while myself was fiddling around Kinect. Ran out of ideas we both met together and thought of integrating everything and that is when we came up with the idea of building our own home security. We started building this application as early as September 2011. And by now, we have already revised the application more than 5 times due to newer SDK release and also due to the addition of newer components.

TechEd India 2012 – Presenting On "Windows Azure With Windows Phone, Windows 8 Metro And Kinect”

I am very happy and excited to announce that this TechEd I will be presenting along with my friend Jebarson. We will be presenting a session which will showcase the integration onWindows Azure, Windows Phone, Windows 8 Metro and Kinect.

imageFor the presentation we have developed a proto solution for Home Security. Well let me explain how we have put all these technologies into action. The Kinect device will serve as a watch dog at the home which is connected to the Azure. The device will be uploading patrol images to the Azure on regular intervals. Once there is a human intrusion detected, the Kinect will send a alert to the Azure and also will start streaming the live video to the Smooth Streaming Server hosted on Azure. Once the Azure, receives the alert, it will send a notification using Microsoft Push Notification Server (MPNS) to the subscribed Windows Phones and Windows 8 Metro apps where you can watch the video streamed live from the Kinect. Well, that’s not the end, we will also demonstrate on controlling Kinect from Windows Phone / Windows 8 Metro app using Azure App Fabric.

We will be discussing all the technologies involved and the architecture of the complete solution extensively along with a live demonstration in the TechEd.

Development With Kinect .NET SDK (Part IV) – Connecting Multiple Kinect Devices with System

This is the fourth post in the series of Development With Kinect .NET SDK. In few of my previous posts I have covered Setting up Kinect Devices and Getting Started with Kinect Development ( Part I) , Exploring NUI APIs with Camera ( Part II)  and Adjusting Kinect Camera Angle (Part III). Till now whatever I have covered, that comes under dealing with  single  Kinect devices. Let’s have some more fun with multiple Kinect devices.  The Kinect .NET SDK does provide support for multiple Kinect devices.   In this post I am going to discuss how you can configure two devices with your system.

Development With Kinect .NET SDK (Part III) – Adjusting the Kinect Camera Angle

This is the Part III of my Kinect .NET SDK Development series post. In past two posts I have discussed about  Installation of Kinect Devices along with setting up your development environment and Exploring NUI APIs with Camera. In this post I am going to cover some more fundamental stuff of Kinect Camera. Kinect .NET SDK provides some API to interact with motorized tilt ( Check out the device details section of first post for more information )  to enables the camera up (+27 Degree)  or down (-27 degrees) .  To adjust the motorized tilt  you need to  set the NUI Cameras ElevationAngle property to a value between –27 and +27.

Development With Kinect .NET SDK (Part II) – Using NUI APIs with Camera

In my previous post Development With Kinect .NET SDK (Part I) – Installation and Development Environment Setup I discussed about  fundamentals of  Kinect sensors and developing application using Kinect .NET SDK. I also explained different types of API that mainly used for interacting with Kinect Device. Natural User interfaces (NUI) and Audio are the core APIs stack for Kinect sensors and  and in the previous article we starts with NUI APIs. By this time you must know how to get start with of NUI API’s by initializing the runtime. Let’s take a inner look of NUI API. In this post I will discuss about NUI APIs for Kinect .NET SDK and will see how we can interact with Kinect Camera Sensors using it.

Development With Kinect .NET SDK (Part I) – Installation and Development Environment Setup

The Kinect SDK is a developer toolkit for developing applications. This SDK provides a fantastic interface to interact with Kinect programmatically. The Kinect for Windows SDK beta includes drivers that interact with H/W and provides an interface to interact with device, APIs for  interacting with  Camera, Sensors, microphone and Motor. The SDK provides capabilities to the developers who build applications with  C#, VB or C++  with Visual Studio 2010  which is running on Windows 7. I started developing application with Kinect SDK almost 2 months back, from the day when I received my Kinect Device. I tweeted about my first application over here  and I am still learning about the Kinect SDK API’s and how to use them in different ways. Let’s share the learning over here. I will keep posting as step by step to allow you to  understand the API’s and get inside Kinect development. I will write a series of post where I will discuss about fundamentals of Kinect SDK API and developing Application using it and yes Step by Step and obviously with Demo Project
