Well, consider that in a few years for AR we won't be using a headset anymore, but just glasses. That won't ruin our hair or skin. But still, I want a see-through display. That was my point.
I want to see the world in first person.
That’s the dream, but then comes the reality. Where do you put a battery, SoC and sensors in normal reading glasses size? Even the battery and SoC of the Apple Watch are too big for reading glasses form factor.
You must completely remove science fiction from your mind. You must think about :
1 user friendliness, comfort, it must feel natural, the weight must not be distracting.
2 it must not leave any physical marks on user’s face.
3 the battery must be able to last at least 10 hours (equal to a working day including travel times) and must not lose 50% battery capacity within 2 years.
4 the operating system and apps must be very lightweight, fast and bug free.
5 unlike all other devices, an AR device’s operating system and apps can’t slow down after major updates otherwise the user will physiologically suffer from their reactions to unpredictable lags, slow graphics, app crashes, etc.
6 the apps must not encourage too much head movement otherwise the neck and spinal column will suffer from tiredness and wear and tear (Early ageing).
It will either take more than a decade to achieve every one of the points, or all points will never be achieved together In one device.
Without achieving all conditions in one device it fails to satisfy all user demands, remains a niche or very imperfect product.
When has Apple reduced the size of their products lately? MacBook Pro 15 became 16. 13 is being replaced with the 14. The MacBook Air grew. The iPhone, iPad and Watch introduced larger sizes. So if you want more and more processing power and battery life, even if your SoC becomes more energy efficient, it becomes very hard to maintain a small form factor.
