Those who love art know it: it is difficult to find the words to explain the emotions you feel when you are standing in front of a sculpture by Canova, Donatello or Bernini. Equally complex it is to describe how incredible it may be the experience of admiring the Pietà by Michelangelo, turn around it, rotate it with your own hands, make it smaller and move it on a desk. The tool that make this possible is Microsoft HoloLens, the first stand-alone holographic computer that allows people to get in touch with digital content, interact with holograms and to obtain the access key for Mixed Reality.
is a jump into the future.
Physically it is a viewer, a pair of glasses, easy to wear
and to adapt to anyone, thanks to the adjustment mechanism. These glasses do not protect people from the sun and do not improve their sight, but allow them to see objects, scenarios and holograms within the environment around. This wearable device can integrate these objects perfectly into reality, and allow them to become a part of a new reality
The magic is due to the hardware behind the lenses, HoloLens actually mounts a real PC on board with a quad-core CPU, a GPU, a holographic processor dedicated to the projection of holograms (HPU), a 2GB RAM memory and 64GB of internal storage. For this reason, you may guess that you do not need a support computer, unlike some virtual reality (VR) viewers.
Not only seeing, but also touching, hearing and speaking
: thanks to the sensors on board, the device is able to interpret voice commands, recognize hands and gestures and therefore respond to the inputs.
There are two loudspeakers, each over the right and left ear respectively, which guarantee the effect of "Spatial Sound": we will have the possibility, by moving to an environment, to distinguish where the sounds come from because the intensity varies depending on the distance and direction of the source.
Once the HoloLens are worn and the system started, the scan of the surrounding environment begins. The device, at this point, capture space data in order to place holograms with absolute precision.
Immediately after, you will find in front of you a floating menu containing all the installed applications that are highlighted on the basis of how the head moves, because the cursor of this computer is the user’s gaze.
How do you interact with it? Naturally with your hands or with your voice, HoloLens is perfectly able to understand the commands
, so you can decide whether to take on the role of John Anderton or Tony Stark with Jarvis.
The key gestures are two: “bloom” and “air tap”
. The first one is used to open or close the main menu, the gesture to be performed is a closed fist that opens; the second one is used to make a selection, a “tap” like the one on a smartphone display, but without a screen, it turns into “an air tap”, that is a “tap into the void”.
The fields of application are of many kinds and the experience is always incredibly realistic and immersive
: within a room we could be catapulted into environment thousands of miles away, and be able to walk inside and always have the knowledge of the movements, thanks to the possibility of mapping environments and sounds in three dimensions.
It is possible to bring to our eyes anything a 3D modeler is able to realize, the feeling will always be the one of having that object really where we have positioned it
, thanks to the holographic resolution of 2.3 million light points.
The possible actions to be performed on these objects are many and varied, just have to get a little inventiveness, we could just admire a sculpture, bringing it closer to our gaze, or add multimedia content, highlight details, modify it, create a real game or a teaching tool.
The possibilities are really endless, our mind is the source, HoloLens
the tool to make it real and that catapults us into Mixed Reality
, a future that has never been so present.

Since I was a child I have loved knowledge and the why of things, this strong passion led me to deal with research and development. I dream of being able to realize something useful to others through my work.
I am also an art and music lover, I dabble in piano and I like singing.
