Technology Overview


11/48

Typically software based-Not requiring specialcameras or sensors Requires 3 steps

Segmentation Separates pixels around the hands or body from background

scene Feature detection

Statistical- based on center of equivalent rectangle Contour- based on the outline of users hands or body

Gesture recognition Directional (Left, Right, Up, Down)

Action Based (Point, Reach, Grab, and Select) Custom libraries

(Du & Li, 2000)


12/48

Uses embedded or separate device based cameras,projectors, and sensors to sense depth and motion Microwave

Low-power, 9-15 GHz, approx. 2-3cm wavelength Gaze, Eye and Facial Gesture tracking

Light Waves Multi-Camera Triangulation Time of Flight (CW or Modulated IR) Structured Light (Grid or Pseudo Random IR) Laser (Object Tracking and Scanning)

Ultrasonic Waves

Basic low resolution/Single Pass Uses shifts in Doppler frequency to recognize movement

(Castaneda & Navab, 2011; Kalgaonkar & Raj, 2009)


13/48

(Castaneda & Navab, 2011)

Measures depth by recognizing returndifferences in infrared (IR) light that has beenreflected off the user Continuous Wave

Measures phase shift of return wave

Pulse Modulated Measures absolute pulse return time

Image: Jeff Ludvick


14/48

Projects IR light into a known pattern andinternal triangulation enables the device torecognize users place within scene Produces a 3D map of the reflected IR returns and

re-calibrates it to projected pattern Depth and movement are obtained by continuously

remapping the current scene and computing theshift from the previous scene

Can use a combination of Grid and/or Pseudo

Random Speckles

(Castaneda & Navab, 2011)

$2,000 reward to the first person who can deliver afully workable Open Source Driver

Later that day after an article on CNET.comMicrosoft responds with significant disdain andthreatens that theyre going to work closely withlaw enforcement and product safety groups to keep

Kinect tamper-resistant Adafruit raises the prize to $3,000 stating the

companys response as the reason for the increase

On Feb 21st2011 Microsoft announces Kinect forWindows Software Development Kit will be releasedin Spring 2011Former employee and key Kinectdeveloper confesses (on his blog) that he put up

the $3,000 reward Kinect for Windows beta SDK released in June 2011

Enabled non-commercial development of applications forKinect.

Company creates official project pages, blog, andKinect Website to highlight what new andinnovative projects people are creating with theKinect.

What is Disruptive Technology?


32/48

Have very different package ofattributes mainstream customershistorically valueoften perform far worsealong one or two dimensions important to

those customersmainstream customersare unwilling to use a disruptive product inapplications they know andunderstanddisruptive technologies tendto be used and valued only in new markets

or new applications; in fact, they generallymake possible the emergence of newmarkets

(Bower & Christensen, 1996)


33/48

The following were disruptive because theyenabled people to do things that theycouldnt previously do with existingtechnologies: Telephone Transistor Radio Photocopier Personal Computers

Digital Photography Each had significant trade-offs, as the

disruption occurred they were overcome

(Christensen, Anthony, & Scott, 2003)

Is Gesture Recognition a

Disruptive Technology?


35/48

1. Signals ofChange

3. StrategicChoices

2. CompetitiveBattles



36/48


Description Disruptive Technology Theory Evaluation

Are there signs that someone iscapitalizing on opportunities for

change?

Serving nonconsumers byintroducing a disruption that

was previously not convient, tooexpensive or more

technologically advanced forthem to acquire.

As a new market innovatorMicrosoft has introduced apackaged that is convient,inexpensive, and does not

require the user to have specialskills to use it.


37/48



What is the likely result of headto head battles?

The new market entrant has

unique and/or abundantresources and is applying themin a way that causes incumbents

to fail.

Microsoft is flush withresources. One of the top

software firms in the world. Thisis no start up. Incumbents are

scrambling for investments andpartnership with other industry

powerhouses.


38/48



Are firms making decisions thatincrease or decrease their

ultimate chances for success?

Successful disruptors harnessthe forces of disruption by

selecting the right value networkand marketplace to make their

stand.

Microsoft used the Xbox 360,the most popular video gamingdevice on the market as their

launch pad for Gesture

Recognition. Additionally, theyhave adopted a previously

successful communitydevelopment approach to helpthis technology further gain a

foothold. Incumbents have beenforced into "also ran position

within the marketplace.


39/48

Is Gesture Recognition a Disruptive

Technology?

Yes!!!

It is highly likely that Gesture Recognition is in fact a

Disruptive Technology. The Kinect could act as the vehicle for this disruption.

This is inline with both the definition of and theorybehind Disruptive Technology

Microsoft satisfies the 3 Step Process that helpsdetermine if an industry is ripe for disruption.



40/48

Implications for Systems

Engineering?


41/48

Exponential growth is deceptive. It startsout almost imperceptibly and then explodeswith unexpected furyunexpected, that is,if one does not take care to follow its

trajectory

(Kurzweil, 2006)


42/48

Requirements Definition & Analysis Understand thresholds for Gesture Recognition performance as it relates

to stakeholder requirements or expectations. Ground Truth vs. MarketingI want to be able to use an Xbox Kinect to! Determine parameters will be used to define performance?

Architectural Design Identify architectural implications of adding Gesture Recognition into the

system architecture. Are Gesture Recognition interface requirements creating an issue for the

systems affordability/ROI?

Does Gesture Recognition play well with othersInteroperability Issues?

Implementation & Integration Gesture Recognition may evolve quickly so a balance must be maintained

between selecting system element solutions too early or too late in the

process. Too early and you negate enhanced capabilities and opportunities for cost

savings Too late and you risk adopting technology that has advanced past your

architectural interfaces. REWORK!


43/48

In general, international standards and bestpractices do not exist for Gesture Recognition

This poses some challenge for Systems Engineers

Bright spots do exist OpenNi is an industry-led organization to promote

compatibility and interoperability of Natural Interaction(NI) devices applications and middleware.

Point Cloud Library (PCL) is a cross platform set ofalgorithms for creating data structures that represent a

collection of multi-dimensional points to recreate orrepresent 3D objects.
