Wayfair takes augmented reality, Project Tango to the enterprise

With the app, customers would be able to see how a piece of furniture fits in their living room

Virtual and augmented realities aren't just for gaming.

Wayfair Inc. , a Boston-based, 14-year-old e-commerce company that sells home furnishings, is working on an app based on Google's Project Tango technology that would put augmented reality, and one day virtual reality, squarely in the enterprise.

If all goes as planned, customers using Wayfair's app would go beyond looking at a photo of a love seat or table, reading the measurements and wondering how the piece would look in their living room.

The app would use Project Tango's mapping, computer vision, depth-sensing, 3D-motion tracking and machine-learning technology to allow customers to see – on their Android smartphone or tablet – how a piece of furniture would look in their home.

If a customer walks around a room with the app running on a tablet, for instance, it would appear as if the object is in the room and she's seeing it from different angles on the screen.

"This really makes sense for our business model," said Mike Festa, director of Wayfair Next, the company's research and development lab. "It's an extension of our experience. ... It will really help us compete with brick-and-mortar stores. It also should help with the rate of returns because it helps customers see the real one-to-one size of the product."

With online shopping, customers get the measurements and dimensions for a product, but no sense of the space needed.

The new app, according to Festa, should help overcome what is a big problem for e-commerce companies.

"The Tango app lets you see a life-size version of the product so you can get a quick analysis of if it's a good fit or not," he added. "In this case, you can see what a 3-foot-wide love seat looks like in your space, and you can make a more informed decision."

"This type of app shows the potential for augmented reality and how it can be used by enterprises to give their customers a much better feel for their products and even services," said Dan Olds, an analyst with The Gabriel Consulting Group. "I can see a wide variety of businesses adopting this approach as the technology becomes better. Architects and contractors will be able to show homeowners exactly how a new addition will blend onto their existing home, for example. Retailers will be able to show you how a particular outfit will look on you. All of this allows consumers to make more informed decisions."

Patrick Moorhead, an analyst with Moor Insights & Strategy, said he expects consumers will be intrigued with a Project Tango app.

"If the app does everything it says it will do, and does it quickly, accurately and looks representative of reality, then I think it will do quite well," Moorhead said. "Accuracy is very important with this app, and if it's off by a half inch, it could be an issue. Speed is important, too, as consumers don't want to wait around for long... If it doesn't deliver on those vectors, it will become a problem."

Wayfair was one of the companies Google touted at I/O, its annual developer conference in Mountain View, Calif., last week.

The company's sessions on Project Tango created a lot of interest with its demo of how organizations, including Wayfair and the American Museum of Natural History, are using it.

First announced in 2014, Project Tango gives devices the ability to know their position in the world, using sensors and other technologies, and processing the information quickly, without using GPS or other external signals.

Google said it has incorporated basic Tango APIs into Android N, the next version of Google's mobile OS, which is expected to be released late this summer.

Lenovo is expected this summer to release the first of what Google says will be "many, many" Project Tango-enabled smartphones. More information on the smartphone, including a release date, is expected at Lenovo's Tech World conference on June 9 in San Francisco.

When that first Tango-enabled device reaches the market, Wayfair wants its app to be ready to go.

Wayfair first entertained the idea of a Project Tango app last summer when Festa built a proof-of-concept app during a company hack-a-thon.

The idea caught on and the company began working on what will be the official Wayfair Tango app in January.

The company has about 3,000 of its approximately 7 million products on the app. Festa said the company can add about 10,000 products per month and hopes to have tens of thousands ready by the time the app goes live this summer.

At this point, Wayfair is focused on creating an app that will work on a two-dimensional device screen. It's an augmented reality application, where the user sees the real world, but artificial, computer-generated content is placed in it.

One day, though, Festa said he hopes Wayfair will have a virtual reality app where customers will use headsets.

"Seeing it on a device on a two-dimensional screen is a lot more natural and a lot more now," said Festa said. "With a lot of virtual reality or augmented reality, you need the headsets. That can be really intimidating. With Tango, people can get this now and it's an immediate adoption that I think we'll see because it'll be more approachable… There's a lower barrier to entry. There's a lot of potential for what VR could be but not for right now."

8 free online courses to grow your tech skills


The cost of learning just got cheaper. CIO.com tracked down these eight free ways to grow your technology skill set.

Free Online Tech Courses
At one time, universities and colleges were institutes of higher learning for those who were passionate about acquiring knowledge. Today, education discussions tend to to center around how much individuals can make with their degree. Thanks to the Internet there are still places that offer open learning initiatives designed to help a new generation of technologists succeed.

If money was the only thing holding you back from learning more about technology, we've got good news for you. There are many places offering free online tech training that while may not be degree/certificate driven can still give you a leg up on the competition.

While many of the courses listed here offer either a certificate or credit for a fee, they also all are free for those who just want to learn about technology or add a new skill to their "toolbox."

Introduction to Linux
Have you always wanted to learn more about Linux but never had the extra cash to inveset. This course offered through edX might be just what you're looking for. The Linux Foundation partnered with edX to offer this free Introduction to the Linux that covers familiarity with the graphical interface and command line as well as a look at all the major Linux distributions. The course gives an over view of the day to day working environment of a Linux administrator and covers pertinent tools and skills.

The designers of the course estimate that a total of 40- 60 hours of study are required to accurately cover the material. Students have the option of auditing the course, at no cost. You get access to course materials, tests, assignments and activities. Those who audit and complete the course will receive a certificate of achievement, but for those wanting to add it as a bullet point on their resume there is a verified certificate available for a fee.

Google Analytics Academy
With the proliferation of the Web, online shopping and social media marketing, competition for organic search traffic has gone through the roof. Understanding your website's analytics can help you make better data-based decisions while at the same time improving the customer experience. Google knows this and would love for you to use its product, Google Analytics. So much so that they've created this online learning center that offers courses to help you better use the hidden data located within your site.

Building Mobile Experiences
Another MIT offering through edX, Building Mobile Experiences, looks at the foundation for building mobile experiences. Mobile app traffic accounted for 55 percent of Web usage, surpassing desktop to become the dominant percentage of internet traffic, illustrating the need for today's developer to become acquainted with the process, design and skills necessary to build the next "big thing."

Based on a poplar MIT class that's been taught since 2006, Building Mobile Experiences' primary focus explores the analysis of mobile user behavior and the implementation of those findings in the design process. The course length is 12 weeks and requires roughly 10-12 weeks of study per week. While there is some code writing required, the bulk of the course will be designing and evaluating what a "unique mobile experience" is.

Students can pay to receive a verified certificate of achievement or audit the course for free and receive and Honor Code Certificate.

Microsoft Virtual Academy
Microsoft Virtual Academy offers a host of courses on mainly -- you guessed it -- Microsoft products. They offer courses on everything from game to cloud to app development and many more. There is no cost to participate but you must use a Microsoft account and create an MVA profile. Once you're logged in you can take courses or attend live events as well as build a learning plan and track progress towards your goals.

Udacity
Udacity got its start when Stanford University starting offering free computer classes in 2011. In April 2014, it boasted more than 1.6 million users. Its free tech offerings include HTML , Python, Intro to Data Science and many more. In fact, Google recently partnered with Udacity to bring Android development to the masses. Individuals who access the courses for free get access to course materials, like instructor videos and project instructions.

Alison
Alison offers an array of free online technical courses covering everything from, building an online business, to C programming to several flavors of Adobe training. One of their more popular tech courses is, ABC IT - Computer Training Suite which teaches users the basics of computing.

Altogether the e-learning provider reports more than 3 million have used its solutions to get educated and they offer more than 600 courses. They have roughly 106 technology courses available in their Digital Literacy and Skills section.

QUESTION 2
Characterizing an existing network requires gathering as much information about the network as
possible. Which of these choices describes the preferred order for the information-gathering
process?

A. Site and network audits, traffic analysis, existing documentation and organizational input
B. Existing documentation and organizational input, site and network audits, traffic analysis
C. Traffic analysis, existing documentation and organizational input, site and network audits
D. Site and network audits, existing documentation and organizational input, traffic analysis

Answer: B

Explanation:
This section describes the steps necessary to characterize the existing network infrastructure and
all sites. This process requires three steps:
Step 1. Gather existing documentation about the network, and query the organization to discover
additional information. Organization input, a network audit, and traffic analysis provide the key
information you need. (Note that existing documentation may be inaccurate.)
Step 2. Perform a network audit that adds detail to the description of the network. If
possible, use traffic-analysis information to augment organizational input when you are describing
the applications and protocols used in the network.
Step 3. Based on your network characterization, write a summary report that describes the health
of the network. With this information, you can propose hardware and software upgrades to support
the network requirements and the organizational requirements.


QUESTION 3
You want to gather as much detail as possible during a network audit with a minimal impact on the
network devices themselves.
Which tool would you use to include data time stamping across a large number of interfaces while
being customized according to each interface?

A. RMON
B. SNMPv3
C. NetFlow
D. Cisco Discovery Protocol

Answer: C

Explanation:


QUESTION 4
Which three are considered as technical constraints when identifying network requirements?
(Choose three.)

A. Support for legacy applications
B. Bandwidth support for new applications
C. Limited budget allocation
D. Policy limitations
E. Limited support staff to complete assessment
F. Support for existing legacy equipment
G. Limited timeframe to implement

Answer: A,B,F

Explanation:
Network design might be constrained by parameters that limit the solution. Legacy applications
might still exist that must be supported going forward, and these applications might require a
legacy protocol that may limit a design. Technical constraints include the following:
Existing wiring does not support new technology.
Bandwidth might not support new applications.
The network must support exiting legacy equipment.
Legacy applications must be supported (application compatibility).


QUESTION 5
In which phase of PPDIOO are the network requirements identified?

A. Design
B. Plan
C. Prepare
D. Implement
E. Operate
F. Optimize

Answer: B

Explanation:



Plan Phase
The Plan phase identifies the network requirements based on goals, facilities, and user needs.
This phase characterizes sites and assesses the network, performs a gap analysis against bestpractice
architectures, and looks at the operational environment. A project plan is developed to
manage the tasks, responsible parties, milestones, and resources to do the design and
implementation. The project plan aligns with the scope, cost, and resource parameters established
with the original business requirements. This project plan is followed (and updated) during all
phases of the cycle.
