The document discusses the capabilities and features of the HoloLens augmented reality headset. It describes how HoloLens blends interactive holographic content with the physical environment using features like gaze input, gesture input, voice commands, spatial mapping, and spatial sound. It provides examples of how these features can be used to build immersive experiences and applications for storytelling, exploration, collaboration, and more. Resources for developing for HoloLens using tools like the HoloToolkit and Windows Holographic platform are also mentioned.
23. • used for targeting and intent
• uses position and orientation of your user's
head, not their eyes, to determine their gaze
vector
• laser pointer from between the eyes
• as the user looks around app intersects this
ray, both with its own holograms and with
the spatial mapping mesh to determine
what virtual or real-world object your user
may be looking at.
• implement a cursor in HoloLens that
represents the user's gazeGaze Input
24. • allows interaction with hologram with hands or clicker
• gestures recognized by tracking position of either or
both hands that are visible to the device
• hands: ready state + pressed state
• clicker
• within the gesture frame
• 2 main gestures:
• Air-tap – activate a hologram
• Bloom – return to Shell
• app can recognize more by combining presses and
releases with movement of your hand or using a
clicker
Gesture Input
25. • users can gaze at a hologram and speak your command
• voice input is powered by the same engine that supports
speech in all other Universal Windows Apps.
• even without specifically adding voice support to your
app, your users can activate your holograms simply by
saying "select“
• “Hey Cortana” will enable you to do a multitude of things:
check weather, check battery, take a picture, etc.
• Manipulation commands:
• Face me
• Bigger | Enhance
• Smaller
Voice Commands
26. • holograms appear visually where the user's gaze
is pointing but sound can come from all directions;
above, below, behind, to the side, etc.
• use this feature to draw attention to an object that
might not currently be in the user's view
• user can perceive sounds to be emanating from a
source in the mixed-reality world.
• Walk toward it and away
• Behind the user
• sounds should come from realistic places. Eg: bird
chirp from the sky not the groundSpatial Sound
27. • detailed representation of real-world surfaces in
the environment
• apps align with user expectations by providing
familiar real-world behaviors and interactions.
• Placement
• Occlusion
• Physics
Spatial Mapping
28. - xyz coordinate system
- relative to the real world: 1 meter in the
real world is 1 meter in your app
- used to stabilize your hologram in a
realistic way

30. Did you know…
- You can port any Windows 10 PC or Mobile app to HoloLens as a 2D app?
- You can see & record what the HoloLens is seeing by using the Windows Device Portal on a PC? Great
way to do demos for a large group.
- You can take a screenshot or a video
- “Cortana, take a picture”
- “Cortana, start recording”
…and immediately share on social
- The sharing experience (multiple people seeing the same hologram) can be used out of the box from the
HoloToolkit
- People feel like holograms are real
- If you place a holographic elephant in the room, people will walk around it, not through it
- If you are in a shared experience and others are shooting holographic projectiles at you, you’ll duck
