Designing the future of Augmented RealityCarina Ngai
Presented on March 4th, 2016 at Interaction16 in Helsinki, Finland.
Until now, augmented reality has so far been mostly a sci-fi vision that overlays visual information to what we see in the physical world. It’s widely perceived as a “cool and interesting feature” for brands and advertising, but doesn’t have much practicality yet. To harness the real power of AR, which includes geolocation, image recognition, we believe that a more utilitarian visual search would be next.
To design for such possibilities, we begin to question even the fundamental basis of AR. For example, what would AR become beyond a rich visual layer? Will this change people’s motivation and behavior to use AR? How can we redefine AR to be a tool to give augmented information on objects? And how we can speculate its usage in the future?
The utilisation of mobile augmented reality to display gallery
artworks or museum content in novel ways is a well-established
concept in the augmented reality research community. However,
the focus of these systems is generally technologically driven or
only addresses the end user and not the views of the gallery or the
original artist. In this paper we discuss the design and
development of the mobile application ‘Taking the Artwork
Home’, which allows people to digitally curate their own
augmented reality art exhibitions in their own homes by digitally
‘replacing’ the pictures they have on their walls with content from
the Peter Scott Gallery in Lancaster. In particular, we present the
insights gained from a research through design methodology that
allowed us to consider how the views of the gallery and artists
impacted on the system design and therefore the user experience.
Thus the final artifact is the result of an iterative evaluation
process with over 100 users representing a broad range of
demographics and continues to be evaluated/enhanced by
observing its operation ‘in the wild’. Further, we consider the
effect the project has had on gallery practices to enable both
augmented reality designers, and galleries and museums to
maximise the potential application of the technology when
working together on such projects.
Designing for an Augmented Reality worldthomas.purves
How “Augmented Reality” and the mobile web changes everything
Mobile broadband access and ever-smarter phones are shaking the internet out its lofty cloud and bringing the web into the real world. As a result, the old “real world”, and many old ideas and many old business models will be running out of places to hide from the pervasive influence of the net.
Meanwhile, each of our smart phones are in many ways even better than the old clunky tools we used to use to surf the net. Our mobile devices are not only connected but, also bristling with sensors like radios, cameras, microphones, GPS etc. that can directly perceive and interact with the world around you. We’re reaching a point where it’s theoretically possible to point that device at almost anything: a landmark, a product on a store shelf, your friends or a crowd of people; and draw from the cloud and your social graph as much, or perhaps more, relevant information than you ever wanted to know. Oh, and the cloud will be watching you and whatever’s around you as well.
In the new augmented reality, the web surfs you.
The goal of this talk will be to provide you with a fast paced overview of what this new “augmented” reality will mean for how we socialize, for how we sell and market physical products, for architecture, for media and entertainment, for public policy, crime, privacy and, as well, few early signals for what might be the new killer apps.
If all that is not interesting enough, I will also bring free beer.

A Fast Single-Pixel Laser Imager for VR/AR Headset TrackingPing Hsu
In this work we demonstrate a highly flexible laser imaging system for 3D sensing applications such as in tracking of VR/AR headsets, hands and gestures. The system uses a MEMS mirror scan module to transmit low power laser pulses over programmable areas within a field of view and uses a single photodiode to measure the reflected light...
Design of Image Projection Using Combined Approach for TrackingIJMER
Over the years the techniques and methods that have been used to interact with the
computers have evolved significantly. From the primitive use of punch cards to the latest touch screen
panels we can see the vast improvement in interaction with the system. There are many new ways of
projection and interaction technologies that can reshape our perception and interaction
methodologies. Also projection technology is very useful for creating various geometric displays. In
earlier generations, the projector technology was used for projecting images and videos on single
screen, using large and bulky setup. To overcome the earlier limitations we are designing “Wireless
Image Projection Tracking”, which is a system that uses IR (Infrared) technology to track the body in
the IR range and uses their movements for image orientation and manipulations like zoom, tilt/rotate,
and scale. We are presenting a method of mapping IR light source position and orientation to an
image. By using this system we can also track single and multiple IR light source positions and also it
can be used effectively to see the image projection in 3D view. Extension in this technology can further
be useful for future tracking capabilities to implement the touch screen feature for commercial
applications.

These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how Light Field Technology is becoming economic feasible for an increasing number of applications. Light Field Cameras record all of the light fields in a picture instead of just one light field. This capability enables users to change the focus of pictures after they have been taken and to more easily record 3D data. These features are becoming economically feasible improvements because of rapid improvements in camera chips and micro-lens arrays (an example of micro-electronic mechanical systems, MEMS). These features offer alternative ways to do 3D sensing for automated vehicles and augmented reality and can enable faster data collection with telescopes.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

44. Starting simple: Marker tracking
Has been done for more than 10 years
A square marker provides 4 corners
Enough for pose estimation!
Several open source solutions exist
Fairly simple to implement
Standard computer vision methods
49. Tracking challenges in ARToolKit
False positives and inter-marker confusion
(image by M. Fiala)
Image noise
(e.g. poor lens, block coding /
compression, neon tube)
Unfocused camera,
motion blur
Dark/unevenly lit
scene, vignetting
Jittering

Occlusion
(image by M. Fiala)
50. Limitations of ARToolKit
Partial occlusions cause tracking failure
Affected by lighting and shadows
Tracking range depends on marker size
Performance depends on number of markers
cf artTag, ARToolKitPlus
Pose accuracy depends on distance to marker
Pose accuracy depends on angle to marker

56. Natural feature tracking
Tracking from features of the surrounding
environment
Corners, edges, blobs, ...
Generally more difficult than marker tracking
Markers are designed for their purpose
The natural environment is not…
Less well-established methods
Usually much slower than marker tracking
57. Natural Feature Tracking
Use Natural Cues of Real Elements
Edges
Surface Texture
Interest Points
Model or Model-Free
++: no visual pollution
Contours
Features Points
Surfaces
61. Model Based Tracking
Track from 3D model
Eg OpenTL - www.opentl.org
General purpose library for model based visual tracking
62. Marker vs. natural feature tracking
Marker tracking
+ Can require no image database to be stored
+ Markers can be an eye-catcher
+ Tracking is less demanding
- The environment must be instrumented with markers
- Markers usually work only when fully in view
Natural feature tracking
- A database of keypoints must be stored/downloaded
+ Natural feature targets might catch the attention less
+ Natural feature targets are potentially everywhere
+ Natural feature targets work also if partially in view
64. Sensor tracking
Used by many “AR browsers”
GPS, Compass, Accelerometer, (Gyroscope)
Not sufficient alone (drift, interference)
65. Outdoor Hybrid Tracking
Combines
computer vision
- natural feature tracking
inertial gyroscope sensors
Both correct for each other
Inertial gyro - provides frame to frame
prediction of camera orientation
Computer vision - correct for gyro drift
66. Combining Sensors and Vision
Sensors
- Produce noisy output (= jittering augmentations)
- Are not sufficiently accurate (= wrongly placed augmentations)
- Gives us first information on where we are in the world,
and what we are looking at
Vision
- Is more accurate (= stable and correct augmentations)
- Requires choosing the correct keypoint database to track from
- Requires registering our local coordinate frame (online-
generated model) to the global one (world)
72. The Registration Problem
Virtual and Real must stay properly aligned
If not:
Breaks the illusion that the two coexist
Prevents acceptance of many serious applications
73. Sources of registration errors
Static errors
Optical distortions
Mechanical misalignments
Tracker errors
Incorrect viewing parameters
Dynamic errors
System delays (largest source of error)
- 1 ms delay = 1/3 mm registration error
74. Reducing static errors
Distortion compensation
Manual adjustments
View-based or direct measurements
Camera calibration (video)
76. Dynamic errors
Total Delay = 50 + 2 + 33 + 17 = 102 ms
1 ms delay = 1/3 mm = 33mm error
