A review of Microsoft Hololens

By a kind invitation from Microsoft, I had the opportunity to experiment, from a user’s perspective, the new Microsoft Hololens. Basically, I was able to wear them for a while and to interact with a number of applications that were spread around a room.hololens

From the outside, the result is not very impressive, as the picture above shows. In a room, which was mostly empty (except for the other guests, wearing similar devices), you can see me wearing the lenses, raising my hand to pull-up a menu, using the menu-pull up gesture.

From the inside, things are considerably more interesting. During configuration, the software identifies the relevant features of the room, and creates an internal model of the space and of the furniture in it.

Applications, both 3D and 2D, can then be deployed in different spaces in the room, using a number of control gestures and menus. Your view of the applications is superimposed with the view of the room, leading to a semi-realistic impression of virtual reality, mixed with the “real” reality. You can move around the 3D holograms in the room (in this case an elephant, a mime and a globe, like the one below, among others).

You can also interact with them using a virtual pointing device (basically a mouse, controlled by your head movements). 2D applications, like video-streaming, appear as suspended screens (or screens lying on top of desks and tables) and can be controlled using the same method. Overall, the impression is very different from the one obtained using 3D Virtuall Reality googles, like Google Cardboard or Oculus Rift. For instance, in a conversation (pictured below) you would be seating in a chair, facing an hologram of your guest, possibly discussing some 3D object sitting between the two.

Overall, I was much more impressed with the possibilities of this technology than I was with Google glasses, which I tried a few years back. The quality of the holograms was quite good, and the integration with the real world quite convincing. The applications need to be developed, though.

On the minus side, the device is somewhat heavy and less than comfortable to wear for extended periods. This limitation could probably be addressed by future developments of the device.
