It’s that time again… to DC!

Halfway there – I’m traveling to Washington, D.C. to meet and educate elected officials and regulators on the booming tech industry. As a leader in the field of custom app development, InterKnowlogy – and so many of our clients – are greatly affected by the policies that our elected officials author and support. It’s an important reminder that our voices DO count, people listen, and we each have a responsibility to get involved.

As part of ACT | The App Association’s annual fly-in, I’m joining more than 50 small tech companies from across the country to advocate for an environment that encourages innovation and inspires growth.  Our message is simple. Small companies like ours are creating solutions that are improving lives, creating jobs, and invigorating our economy.  The creativity that comes from these discussions is amazing, and the energy inspires each of us to go out and craft our message in a way that is unique to each of our environments.

Policymakers in Washington must understand issues threatening small tech companies to ensure growth continues. The concerns we will raise next week include data privacy and security, internet governance, intellectual property and patent reform, mobile health regulation, and regulatory obstacles to growth. These are important issues for which the federal government is considering taking action.

I look forward to meeting with my elected officials and others in Washington to educate them about the tech industry so they can make the right decisions about our future. Hopefully, an informed Congress will help entrepreneurs continue to flourish.

Follow our activities at, or via Twitter @EmilieHersh, and @ACTOnline – come join in the fun as we make a difference in our collective future!

InterKnowlogy Employees Give Back To Community

nterknowlogy Employees Day of Giving

InterKnowlogy colleagues volunteered with Habitat for Humanity as part of the company’s Day of Giving event. InterKnowlogy is known for its incredible company culture and community spirit, with employees who are as passionate about creating innovative technology as they are about the place they live. Volunteers pitched in to work on a job site in Escondido, where future family homes were in different phases of construction. Over half the company’s employees participated in the event and spent the day installing roofing, hanging drywall and painting. The sense of teamwork was magnified when the employees joined together to make an impact in the community, creating awareness about the need to improve living conditions for low-income families.

“I have always been an advocate in giving back, and there are so many ways in which we can all do so – even better when we can do it together. The people at IK make it not only possible, but it is the reason we come to work and excel each day. It is truly my pleasure to work side-by-side with everyone here and give back to those in our community who need the most help!”

—Emilie Hersh, CEO of InterKnowlogy

A Day of Giving is organized each quarter by committee and gives employees the opportunity to find volunteer opportunities that can be done as a group. Seeing the great attitudes and desire to help improve the lives of those less fortunate than ourselves is truly rewarding.

Art Center College of Design Interaction Design Workshop

Art Center of Desing LogoInteraction Design (IxD) is used for much more than web sites and simple mobile apps. Companies are solving complex problems, and they can use IxD principles to make sure they are building the right thing the first time without writing novels of requirements documents. Rodney Guzman, Chief Architect and founder of InterKnowlogy will lead an interaction design workshop at the Art Center College of Design. Students will explore how InterKnowlogy works with customers to understand the features they need, and how we echo back what is heard. Students will have the opportunity to listen and observe a real interview with a product stakeholder. Afterwards, the students will work as team to write a proposal for the work. Our goal is to give the students a real life scenario of getting from an idea to effectively communicating a solution.

Kinect 2.0 Face Frame Data with Other Frame Data

Do you have a project that you are using the Kinect 2.0 Face detection as well as one, or more, of the other feeds from the Kinect? Well I am, and I was having issues with obtaining all the Frames I wanted from the Kinect. Let’s start with a brief, highlevel, overview, I had a need to obtain the data relating to the Color Image, the Body Tracking, and the Face Tracking. Seems very straight forward until I realized that the Face Data was not included in the MultiSourceFrameReader class. That reader only provided me the Color and Body frame data. In order to get the Face data I needed to use a FaceFrameReader. Which required me to listen for the arrival of two frame events.

For example, I was doing something like this.

public MainWindowViewModel()
	_kinectSensor = KinectSensor.GetDefault();

	const FrameSourceTypes frameTypes = FrameSourceTypes.Color | FrameSourceTypes.Body;
	MultiSourceFrameReader kinectFrameReader = _kinectSensor.OpenMultiSourceFrameReader( frameTypes );

	kinectFrameReader.MultiSourceFrameArrived += OnMultiSourceFrameArrived;

	const FaceFrameFeatures faceFrameFeatures = 
		| FaceFrameFeatures.RotationOrientation
		| FaceFrameFeatures.FaceEngagement;

	faceFrameSource = new FaceFrameSource( _kinectSensor, 0, faceFrameFeatures );
	faceFrameReader = faceFrameSources.OpenReader();
	faceFrameReader.FrameArrived += OnFaceFrameArrived;

	_kinectSensor.IsAvailableChanged += OnSensorAvailableChanged;


private void OnMultiSourceFrameArrived( object sender, MultiSourceFrameArrivedEventArgs e )
	//Process Color and Body Frames

private void OnFaceFrameArrived( object sender, FaceFrameArrivedEventArgs e )
	//Process Face frame

In theory, this should not be a problem because the Kinect is firing off all frames at around 30 per second and, I assume, in unison. However, I was running into the issue that if my processing of the Face data took longer then the 30th of a second I had to process, the color or body data could be at a different point in the cycle. What I was seeing was images that appeared to be striped between two frames. Now I understand that this behavior could be linked of various issues that I am not going to dive into in this post. But what I had noticed was the more processing I tried to pack in to the Face Frame arrival handler, the more frequently I saw bad images. It is worth noting that my actual project will process all six of the faces that the Kinect can track, and when having to iterate through more then one face per frame, the bad, striped, images were occurring more then good images. This lead me to my conclusion (and my solution lead me to write this blog.)

I also did not like the above approach because it forced me to process frames in different places, and possibly on different cycles. So when something wasn’t working I had to determine which Frame was the offender, then go to that processing method. No bueno.

In trouble shooting the poor images, I had the thought “I just want the color and frame that the Face frame using.” Confused? I’ll try to explain. Basically, the Kinect Face tracking is using some conglomeration of the basic Kinect Feeds (Color, Depth, Body) to figure out what is a face, and the features of that face. I know this because if a body is not being tracked, a face is not being tracked. The depth is then use to track if the eyes are open or closed and other intricacies of the face. Anyways, back on track, I had a feeling that the Kinect Face Frame had, at least, some link back to the other frames that were used to determine the state of the face for that 30th of a second. That is when I stumbled upon FaceFrame.BodyFrameReference and FaceFrame.ColorFrameReference (FaceFrame.DepthFrameReference also exsits, it’s just not needed for my purposes). From those references you can get the respective frames.

After my epiphany my code turned into:

public MainWindowViewModel()
	_kinectSensor = KinectSensor.GetDefault();

	//Multiframe reader stuff was here.
	//It is now gone.

	const FaceFrameFeatures faceFrameFeatures = 
		| FaceFrameFeatures.RotationOrientation
		| FaceFrameFeatures.FaceEngagement;

	faceFrameSource = new FaceFrameSource( _kinectSensor, 0, faceFrameFeatures );
	faceFrameReader = faceFrameSources.OpenReader();
	faceFrameReader.FrameArrived += OnFaceFrameArrived;

	_kinectSensor.IsAvailableChanged += OnSensorAvailableChanged;


private void OnFaceFrameArrived( object sender, FaceFrameArrivedEventArgs e )
	var bodyReference = faceFrame.BodyFrameReference;
	BodyFrame bodyFrame = bodyReference.AcquireFrame();

	var colorReference = faceFrame.ColorFrameReference;
	ColorFrame colorFrame = colorReference.AcquireFrame();
	//Process Face frame

private void ProcessBodyAndColorFrames( BodyFrame bodyFrame, ColorFrame colorFrame )
	//Process Body and Color Frames

I still have the processing methods split out similarly to how I had them in the first (bad) way, but with this approach I am a little more confident that the Color and Body Frames and I analyzing are the same ones used by the Face processor. I am also more free to split up the processing as I see fit. The color and body are really only lumped together because that is how I was doing it before. In the future they might be split up and done in parallel, who knows.

And with that, the occurrence of bad images appears to be greatly reduced. At least for now. We will see how long it lasts. I still get some bad frames, but I am at least closer to being able to completely blame the Kinect, or poor USB performance, or something other than me (which is my ultimate goal.)

Not a big thing, just something I could not readily find on the web.

Kinect Development (Face tracking) – Without a Kinect

In a previous post I talked about how you can use Kinect Studio v2 Studio software to “play back” a recorded file that contains Kinect data. Your application will react to the incoming data as if it were coming from a Kinect, enabling you to develop software for a Kinect without actually having the device.

This of course requires that you have a recorded file to playback. Keep reading…

More specifically, Kinect for Windows v2 supports the ability to track not only bodies detected in the camera view, but tracking FACES. Even better, there are a number of properties on the detected face metadata that tell you if the person is:

  • looking away from the camera
  • happy
  • mouth moving
  • wearing glasses
  • …etc…

Here at IK, we have been doing a lot of Kinect work lately. It turns out the Kinect v2 device and driver are super picky when it comes to compatible USB 3 controllers. We have discovered that our laptops (Dell Precision m4800) do not have one of the approved controllers. Through lots of development trial and error, we have narrowed this down to mostly being a problem only with FACE TRACKING (the rest of the Kinect data and functionality seem to work fine).

So … even though I have a Kinect, if I’m working on face tracking, I’m out of luck on my machine in terms of development. However, using the technique described in the previous post, I can play back a Kinect Studio file and test my software just find.

To that end, we have recorded a short segment of a couple of us in view, with and without faces engaged, happy, looking and not, … and posted it here for anyone to use in their Kinect face tracking software. This recording has all the feeds turned on, including RGB, so it’s a HUGE file. Feel free to download it (below) and use it for your Kinect face tracking development.

Sideloading Windows Store Apps – When Unlimited Has a Limit

In part 1 and part 2 of this series, I describe how & where to buy a Windows Sideloading Key and then how to configure a machine to sideloading your “store” application.

I did not think there was another part to this story … until I checked my license and it’s number of activations. The license you purchase and use to sideload Windows store applications is supposed to be for an “unlimited number of devices“.

Unlimited Devices

MS Claim of Activations on Unlimited Devices

You can imagine my surprise and frustration when I saw in the Volume License Service Center that I had burned through 7 of 25 activations in the first few days!!

Long story short, after a few emails with the VLSC, they said they set the number of activations on that “UNLIMITED” license to 25 “for Microsoft tracking purposes on how many times the product has been used“. In the event you run out, you can request more activations by contacting the MAK team.

I do NOT want to be in production and getting calls from a customer that can no longer sideload the application because we have reached the maximum number of activations. Sure enough, it took another couple emails, but the MAK team was “happy” to increase the number… to 225. Still not unlimited, but a somewhat large number that I will someday likely have to increase again.
