8. History of HoloLens
• Codenamed Project HoloLens
• Chief inventor Alex Kipman
• Official title is technical fellow
• He dreamed up Kinect in at the end of 2007
and set a vision which incorporated HoloLens
• It is the start of a transforming world
• In the new reality, sensors will be anywhere
• A visual computing platform controlled by speech and gesture
Satya Nadella - “The emergence of
the next computing interface”

9. “Augment reality is a live direct
or indirect view of a physical,
real-world environment whose
elements are augmented by
computer generated sensory
input such as sound, video,
graphics and data”

10. Different approaches
• Augment Reality (AR)
• Mixed reality
• Interact with the physical, real-
world environment
• Virtual Reality (VR)
• No transparency to the physical
real-world environment

world environment
•Game interaction with your walls,
ceiling and floor
Gaming

18. • A company needs to add additional
electrical wiring.
• Detailed wiring plans are projected
over a wall or ceiling
• Based on detailed plans shown
through HoloLens he can decide
where to add
Example of visualization
Detecting
electrical wiring

19. • Detailed information about the
elevator through a dashboard
• A 3D representation of parts of the
elevator to allow quickly find the
problem
• Ability to contact others through
phone and mail for help
Example of visualization
Elevator
maintenance

20. • Getting better insights of BI data
through 3D models
• Extend the desktop with 2D/3D
information screens
Example of provisioning of
information
Enhance your BI
desktop

21. • Sharing the same view, scenarios
and data of a car simulation with
sensors
• Getting help from each other and
make it easier to explain on what
you are working on
Example of working together
Working
together on
car safety

22. • Getting a realistic 3D projection of
the human body
• It allows easy layering of the body
and mark different body parts
• By walking around the projection
and viewing and marking body parts
will help students to learn more
quickly
Example of education
Learning
about the
human body

23. • Become part of different squares in
Rome
• Rome is viewed as a 360 degree
view around you in all directions
• Images are enhanced wih
holographic additions like the inside
of the church and the fountain in the
front.
Example of media and
entertainment
…

24. • HoloLens allows us to play games
which become part of our real-world
environment
• Fragments is a CSI game in which
you, together with virtual people
solve crime delicts
• Virtual people use your room as if
there are actually there
Example of gaming
Mixed reality
during
gameplay

25. Demo
Holomaps

26. Input controls

27. Gaze
• The direction of the
HoloLens pointing is called
the gaze
• Hits an object or part of
the environment
• Uses a Vector3 based value
to define its so called
“forward” direction

28. Gestures
• Recognize input by tracking the
position of either or both hands
• Gesture frame
• Recognized input from hands
• Bloom
• Press, hold and release
• Follow the hand (my own )
• Gestures
• Hold
• Manipulation
• Navigation

29. Voice
• Use words or sentences to
control your environment
• English language only at the
moment
• Phrase recognition using
Language Understanding
Intelligent Service (LUIS)

30. Sound

31. Cortana
• Start with “Hey Cortana”
• Some thing you can say
• Move <app name> here
• Take a picture
• Start or stop recording
• Call <contact>
• How much battery do i have left?
• Restart or Shutdown
• Cortana can be turned on/off

32. Spatial Sound
• Simulates 3D sound using direction,
distance and environmental
simulations
• Above, below, behind, to the side,
etc.
• Attach sound to holographic objects
• Works also when object is not in line
of sight
• Used to draw attention
• Audio engine in HoloLens
• CPU and memory considerations
• 10-12 spatial sound voices

33. Spatial Sound
• Gaze mixing
• Highlighting objects
• Play a sound on the object to get the
users attention
• Audio Haptics
• Reactive audio for touchless
interactions
• Play a sound when user selects an
object or when his hands appear inside
the gesture frame
• Immersion
• Ambient sounds surrounding the user
• Support your scene with background
sounds or music

34. Spatial Perception & understanding

35. Spatial perception
• Spatial perception and
mapping
• Rooms
• Different ways of detecting
and working with spatial
perception
• Meshes & planes
Spatial perception is the
ability to be aware of your
relationships with the
environment around you
and with yourself

36. Spatial perception
• Device scans your
environment and builds a
digital model in real time
• It allows HoloLens to see
different surfaces, walls
and ceiling
• Possible to simulate a
physical space
• E.g. Projecting a terain
over your floor

37. Demo
Scanning & building

38. Pinning
• Device can project a
hologram into a room and
keep it locked in position
• Called pinnnig
• Objects are not moving
relative to you but you
can move around the
object
• Allows you to view the
object from any angle

39. Other cool stuff

40. Vuforia
• Allows you to develop holographic
apps which recognize specific
things in the environment and
attach experiences to them
• Recognizes specific images and
objects in the environment
• Vuforia engine
• Extend the capabilities of your
holographic app
• Includes support for OpenGL ES 3.x
• Uses Cloud recognition services

41. Sharing holographic experiences
• Two or more people are
experiencing the same
holographic objects
• Accomplished to anchor sharing

42. HoloLens device editions comparison

like OneDrive
• HoloLens does not support
connecting external hard drives
or SD Cards
• There is no File Explorer
application
• You could use the Windows
Device Portal

49. Use case
Contractor has
delivered new
building for
organization
Project Owner
inspects the
building
Anything which is
not correct is
marked for repair
Contractor checks
all marked items
from the inspection
and fixes the issues

50. Use case solution
• Project Owner uses the HoloLens device and walks
through the building
• By using gaze and gestures he indicates areas for repair
• Indicated areas are send to SharePoint Online via Azure
Cloud Services
• Project Owner can add additional information via SharePoint
Online
• Contractor uses the HoloLens device and walks through
the building seeing all markers indicating repairs needed

51. Demo
HoloLens tagging

52. Design considerations

53. User perspective
• Ensure the application is comfortable to the
user
• Avoid abrupt movements
• Allow them to see the world in the
background
• Animation from down, left or right or fade
in
• Move content slowly and smoothly toward
the user
• Keep a minimal distance of 3 meters
• Design your application from an user’s
unique point of view
• Determine if the user moves around
• User is sitting down or standing
• The user is the camera!
• Let them control the movement
Design patterns for
mixed reality

54. Holographic frame
• Use the center of the holographic
frame for your holographic objects
• Help the user through guideness
• Arrows pointing to a specific
location
• Light trails
• Pointers
• Spatial sound
• Voice prompts
• Make sure your holograms fit the
frame
• They will feel natural Design patterns for
mixed reality

55. Content following the user
“body-locked” content
• Placed in an attached frame of
reference
• Holograms are designed to
follow the user
• Floating at a certain distance
and heading
• Reference does not rotate as
the user turns their head
• Userfriendly
“Head-locked” content
• Holograms are continuous
shown at a fixed position within
the display
• Uncomfortable for users
• Not natural part of the world
around you
• Strongly discouraged

56. Embed holograms in the
world
• Use spatial mapping to place
holographic objects on surfaces
• Occlude holograms based on
• Other holograms
• Real-world objects
• Visualize surfaces during placement in
the real world
• Place holographic objects in the
“optimal” zone
• Between 1.25m and 5m
• Take into account the gravitational
rules
• Use shadows projected on real-world
objects
Design patterns for
mixed reality

57. Sharing experience
questions
• How are they sharing?
• What is the group size?
• Where is everyone located?
• co-located, remote or both
• When are they sharing?
• synchronously, asynchronously or
both
• How similar are their physical
environments?
• Similar, dissimilar
• What devices are they using?
• AR, VR, phone or PC
Design patterns for
mixed reality
