About the Hololens
Currently, most headsets in the Mixed/Augmented/Virtual reality world require a hand-held controller. These controllers – a type of wireless joystick – “tell” the glasses where your hands are, often using special LEDs or external sensors. The limit of these controllers also lies with the buttons that you must utilize to access/execute commands. One of the most beautiful features that HoloLens 2 brings compared to all other devices – is the fact that this device can track your hands without a controller. And not only that – the HoloLens 2 supports, ‘fully articulated hand tracking’.
This means that the HoloLens not only follows the location of your hands, but the location of each individual joint in your fingers and thumb, as well as fingertips, the palm and the wrist. That’s a whopping 21 points per hand. This allows the HoloLens to determine how your hand is rotated (i.e., whether you look at the back or palm), how exactly your hand is curved or stretched- and what you do with it. For example, you can press virtual buttons with your fingertips, push away holograms with your hand, pick up holograms, put them somewhere, turn them over, make them bigger and smaller, take them with you, and so on. In a way that is very similar to what you would do with real objects.
More important than all the technical ingenuity and the cool things you can do with it, is the effect this has. A HoloLens is a high-tech device and for many people high tech is synonymous with “complex, difficult and intimidating”. By using advanced hand tracking and the interactions that make this possible, you take away a layer of abstractions. Instead of holding a device in your hands with six buttons, a small joystick and/or a touchpad – just use your hands. Just like in the real world.
The importance of this cannot be overestimated. Just being able to utilize your hands lowers the threshold for using a technically complicated device like the HoloLens. Interacting with virtual objects becomes more natural – you don’t need to learn to use special devices or gestures. This makes the device a lot less intimidating. A lot of things just work the way you’re used to in the real world. The only thing missing is the sensation of touch but that’s a much smaller limitation than having to use a controller or special, unnatural gestures.
Velicus & Mixed Reality
At Velicus, we make full use of these possibilities to ensure that CPR training gets a much more realistic experience. We can determine if you’re tilting the head properly by looking at your fingers. After you have received the AED, put it in the right place, unzipped the suitcase and operated it, you almost forget that you are operating a hyper technical and complex device like the HoloLens.
And that’s what it’s all about: making technology so accessible that it almost seems to disappear. So you can focus on what’s really important – learning to save a life.
