A few months ago, Microsoft Most Valuable Professional (MVP) James Ashley, a leader in developing with Kinect for Windows, wrote a very perceptive blog about Kinect for Windows v2 entitled, Kinect for Windows v2 First Look. James’ blog was so insightful that we wanted to check in with him after being in the Developer Preview program for three months and learn more about his experiences with the preview sensor and his advice to fellow Kinect for Windows developers. Here’s our Q&A with James:
Microsoft: As a participant in the developer preview program, what cool things have you been doing with the Kinect for Windows v2 sensor and SDK over the past few months? Which features have you used, and what did you do with them?
James: My advanced technology group at Razorfish has been very interested in developing mixed-media and mixed-technology stories with the Kinect for Windows v2 sensor. We recently did a proof- of-concept digital store with the Windows 8 team for the National Retail Federation (aka “Retail’s BIG Show”) in New York. You’ve heard of pop-up stores? We took this a step further by pre-loading a shipping container with digital screens, high-lumen projectors, massive arrays of Microsoft Surface tablets, and Perceptive Pixel displays and having a tractor-trailer deposit it in the Javits Center in New York City. When you opened the container, you had an instant retail store. We used the Kinect for Windows v2 sensor and SDK to drive an interactive soccer game built in Unity’s 3D toolset, in which 3D soccer avatars were controlled by the player’s full body movements: when you won a game, a signal was sent by using Arduino components to drop a drink from a vending machine.
We also used Kinect for Windows v2 to allow people to take pictures with digital items they designed on the Perceptive Pixel. We then dropped a beach scene they selected into the background of the picture, which was printed out on the spot as well as emailed and pushed to their social networks if they wanted. In creating this experience, the new time-of-flight depth camera in Kinect for Windows v2 proved to be leagues better than anything we were able to do with the original Kinect for Windows sensor; we were thrilled with how well it worked. [Editor’s note: You can learn more about these retail applications in this blog post.]
Much closer to the hardware, we have also been working with a client on using Kinect for Windows v2 to do precise measurements, to see if the Kinect for Windows v2 sensor can be used in retail to help people get fitted precisely—for instance with clothing and other wearables. Kinect for Windows v2 promises accuracy of 2.5 cm at even 4 meters, so this is totally feasible and could transform how we shop.
Microsoft: Which features do you find the most useful and/or the most exciting, and why?
James: Right now, I’m most interested in the depth camera. It has a much higher resolution than some standard time-of-flight cameras currently selling for $8,000 or $9,000. Even though the Kinect for Windows v2 final pricing hasn’t been announced yet, we can expect it to be much, much less than that. It’s stunning that Microsoft was able to pull off this technical feat, providing both improved quality and improved value in one stroke.
Microsoft: Have you heard from other developers, and if so, what are they saying about your applications and/or their impressions of Kinect for Windows v2?
James: I’m on both the MVP list and the developer preview program’s internal list, so I’ve had a chance to hear a lot of really great feedback. Basically, we all had to learn a lot of tricks to make things work the way we wanted with the original Kinect for Windows. With v2, it feels like we are finally getting all the hardware performance we’ve wanted and then some. Of course, the SDK is still under development and we’re obviously still early on with the preview program. People need to be patient.
Microsoft: Any words of advice or encouragement for other developers about using Kinect for Widows v2?
James: If you are a C# developer and you haven’t made the plunge, now is a good time to start learning Visual C++. All of the powerful interaction and visually intensive things you might want to do are taking advantage of C++ libraries like Cinder, openFrameworks, PCL, and OpenCV. It requires being willing to feel stupid again for about six months, but at the end of that time, you’ll be glad you made the effort.
Our thanks to James for taking time to share his insights and experience with us. And as mentioned at the top of this post, you should definitely read James’ Kinect for Windows v2 First Look blog.
