Two Important Questions About HoloLens

I have written many posts about HoloLens: How HoloLens can transform businesses, entertainment, and our daily life. It’s an amazing piece of technology if it is implemented properly. I have had two questions in mind for some time, and I don’t have answers. I do, however, want to share my analysis and opinions. I hope you find it helpful.

The two questions are: 1. How responsive is the HoloLens to hand gestures, voice and gaze? 2. How does it feel wearing HoloLens, considering its weight (400gram)?

In my opinion, these are two critical questions about HoloLens. The reason they are so important is not only because they directly affect user experience, but also because we have high confidence about other things. These are two areas that we have questions but no clear answers. Now, lets do some analysis.

It is said that hand gesture, voice and gaze are the main user interfaces for HoloLens. As a user interface, number one requirement is being responsive, not sluggishly responsive, but cleanly, crisply responsive. Some journalists who were shown the prototype devices said there was a tiny but noticeable delay. What they have seen was from prototypes, it is not representative to the final product. From the on stage demo, shown to the public, the response seemed very clean. In any case, this is an important question, I am interested in finding out.

The weight is another thing that deserves some analysis. Microsoft had said the final product will weigh 400gram, same as an high end helmet. However, we can’t directly relate a 400gram helmet to a 400gram HoloLens, they are different in shapes. In the helmet, the weight is uniformly distributed around the surface of a half globe. HoloLens is a ring, actually a double ring. 400gram is tiny for a computer, but it is something when you put it on head in the shape of a ring. It’s interesting to know how it feels when you turn your head, and how it feels when you wear it for a long time. I am wondering if the double-ring design has something to do with this in addition to dealing with the heat. I hope so.
