Kinect:Microsoft’s latest billion dollar baby.Technophiles/ Developers latest crush

Posted in New Technologies by Manas Ganguly on January 25, 2011

Kinect is not only one of the best things that has happened to Microsoft after a long time, it also possibly is the most remarkable product after iPhone and iPad. Apart from its impressive numbers, Kinect’s real success is in terms of being able to initiate innovation amongst developers. While Microsoft was initially against tampering of the hardware, the quality of the results that are coming in has forced it to tamper down its strict approach to tampering and jailbreaking.

Its been a long time, and a real long one at that since we heard something very positive and very good from the Microsoft stable. Microsoft has taken a lot of heat for its inability to innovate, but Kinect has proved that Microsoft is still in the game. The controller-free system for the Xbox 360 received almost universally glowing reviews and shipped 8 million units in the first quarter, making it one of the fastest selling tech product debuts in history. It also debuts fastest in the Microsoft $1 billion businesses. At $150 selling price and $59 BOM cost, Kinect is surely raking both margins and volumes.

While this is debatable, the initial inspiration came from Nintendo Wii, whose motion sensitive controller had made gaming more interactive. The idea was to get rid of the controller. Microsoft bought in a few key technologies from external companies mostly in the field of 3D imaging a human-motion sensing camera. With a start as brilliant as 8 million devices, the Kinect has evoked widespread anticipation, excitement and response amongst technolophiles. Kinect’s combination of sophisticated sensors and affordable price are opening up new possibilities for technophiles working in art, filmmaking, robotics and music. What perhaps is the greatest endorsement to Kinect’s abilities is that within a few days after launch it inspired a communal effort at hacking the software and use the Kinect hardware with PCs and other devices with free, open source code. This was called OpenKinect. As a result, the Kinect has already been used in countless ways its creators never anticipated. Within a quarter OpenKinect had 1650 people registered working as a part of open community innovating on Kinect.

Microsoft was initially skeptical. Perhaps recognizing the value of this innovation, Microsoft has since backed off their strict anti-tampering stance, even going so far as to have spokespeople appearing on the Science Friday podcast say that the port being used to connect the Kinect to PCs was “left open by design.”

Kinect was an extension of the NUI project.This Natural User Interface technology, or NUI, is already present on smart phones and tablets that feature multi-touch, pinch-to-zoom and other intuitive gesture-based control systems, but could be expanded to replace the television remote, the mouse and keyboard, and to introduce technology into new avenues of life.

Here are an assortment of the OpenKinect innovations on the Kinect platform:

Kinect Open Gravity

Kinect Illuminous

Kinect Depth Sculpting Probe

Kinect Keyboard Anywhere

Here’s how this genie works (courtesy Paul Miller):

“Kinect combines a few detection mechanisms to build up a rather accurate and comprehensive amount of 3D data on what’s going on inside a room. There’s a color camera for taking pictures, recognizing faces, and so forth, but the real magic happens with the monochrome CMOS camera sensor that’s paired up with an IR blaster. Microsoft calls this its “depth sensor,” and the light and shadow of that image (lit by the human eye-invisible IR spectrum) is analyzed to build a 3D map of the objects within Kinect’s field of view. Finally, there’s a multi-array microphone setup to detect location of voices and to cancel out ambient noise, allowing for video chats without a headset. All of this sits atop a motorized tilting base of sorts, which when used in conjunction with skeletal and facial tracking, Kinect can pan and tilt to keep its sensors trained on you as you move around the room. One down side of the motorized base, however, along with the rest of the fairly complicated electronics, is that the Kinect hardware isn’t tiny: it’s about a hand’s width tall, about as deep, and around a foot wide. When you think about it, the entire Wii occupies less cubic real estate. It shouldn’t have much trouble squeezing in up in front of your LCD TV, but good luck trying to balance it on top, and we have no idea how folks who hang their TVs on the wall should approach this situation.

One thing that Microsoft has actually left out of Kinect is a dedicated processor. The original plan was purportedly to have the Kinect pull its own load, allowing the Xbox 360’s processors to run free in rendering games. In the interest of cost, however, the processor got cut and now the Xbox is taking a 10-15% processor hit. Reports are conflicting as to whether or not that’s going to impact the sort of games that make it onto the system, but either way it pretty much rules out retrofitting older games for a new Kinect control scheme.

There are divergent reports on lag, but 100-150ms seems to be around where Kinect is playing (Sony claims a 22ms lag for PlayStation Move). During that time the system is tracking and processing 48 skeleton points in 3D space, watching up to two people, and repeating the process at around 30 fps.”

Kinect will be bundled along with the Xbox 360 and while the Xbox 360 has a tag of $199, the Kinect bundles will cost $399 for elite and $299 for arcade.

Microsoft has wowed the journos and analysts alike with the experience of real games, real gameplay, and real hardware, and a very real desire to get hands on with this new technology. The wait is set and we have a date with the Kinect, this 4th November 2010.

Microsoft Project Natal finally sees the light of the day November 4th 2010 and it has a new name: Kinect. This is a part of the overall Microsoft strategy to use Natural motions as user interfaces.

The strange alien shaped machine which will be bundled along with the New Xbox 360 has not been named yet. The device specializes in Motion Gaming (which is what Natal was all about) with a dual/multi player capability, three dimensional approximation, Voice control mechanism, Social networking Apps: Twitter, Facebook, Zune and Netflix and a Video Chat App. Click here for more details of the games, device and user experience.

The interface is kept simple: You wave your hand to control a glowing cursor of sorts, and you push forward to “click” on the element you want.

Quoting Paul Miller on the Kinect Lite:
“In some ways, it’s pretty charming, with fun, jazzed up icons (when you hover over them they tilt and show off depth), a simplistic layout, and some great voice controls. The downside is this all comes at the cost of a brand new, fairly redundant interface for accessing functions that are already available with your Xbox 360 controller in the regular Dashboard. Still, there’s no denying the joy of waving a hand to log in, hovering over icons to select channels (though the wait-to-click mechanism strikes us as eventually frustrating), and scrubbing through media with very intuitive gestures.

Microsoft brings Gesture Control to Windows and XBox

Posted in Computing and Operating Systems, Value added services and applications by Manas Ganguly on July 17, 2009

Microsoft has been working on gesture recognition as extension on Microsoft gaming console Xbox. The integration of gesture recognition in its gaming console has been named Project Natal. Depth-sensing cameras such as the one Microsoft is adding to the Xbox allow people to control their PCs, game devices, and televisions. Now Microsoft wants to bring Project Natal and its technology to Windows.


Depth camera would connect up to Windows PCs for interacting in terms of meetings, and collaboration, and communication. This was first conceptualized and developed by Microsoft research and is now being commercialized by both the Xbox and Windows units. The Xbox guys and the Windows guys have now latched onto the idea and Microsoft expects the office applications (coupled with Depth sensing camera) can be quite exciting.

In an interview to CNet, Microsoft Chairman Bill Gates, “Using your body to control devices makes a lot of sense. I think the value is as great for if you’re in the home, as you want to manage your movies, music, home system type stuff, it’s very cool there. And I think there’s incredible value as we use that in the office connected to a Windows PC. So Microsoft research and the product groups have a lot going on there, because you can use the cost reduction that will take place over the years to say, why that shouldn’t be in most office environments.”

Gates actually dropped the first hint of Natal during his joint appearance with Steve Jobs at the D: All Things Digital conference in 2007

“Imagine a game machine where you’re just going to pick up the bat and swing it, or the tennis racket and swing it,” Gates said.

Moderators Walt Mossberg and Kara Swisher mocked Gates, saying such a technology already exists and it’s called the Wii. But Gates disagreed. “No, that’s not it. You can’t pick up your tennis racket.”

He later added, “You can’t sit there with your friends and do those natural things,” he said. “That’s a 3D positional device. This is video recognition. This is a camera seeing what’s going on.”

However, there are doubts about Microsoft’s ability to execute such futuristic moves. It was about 10 years earlier that Microsoft had promised voice controlled computers. 10 years and few many generations of processors later, Microsoft has been no-where close to pioneer voice recognition as an input to computing devices. (It would have put some distance between itself and competitors if it would have executed this strategy). Instead all it has done is to release “delta development” versions, which has left it vulnerable to more innovative competitors.
