Imagining A Future With A Ring

In the future, a "computer", or whatever name we'll call it, can be reduced to a ring. Yes, like the jewelry you can wear everyday. It will not have much to show on its own. But once paired with a display device or appliance, it can become everything we'll want a "personal computer" to be.

Consider a full PC in the size of a ring. It's always on and always online. By itself, your primary actions can include voice commands and listening to its built-in speaker (perhaps via bone conduction). You can link it to a wristwatch form display and it becomes your smartwatch. You can link it to phone form display and it becomes your smartphone. Link it to a bigger display, then you have a tablet. Bigger, a laptop/desktop PC. Bigger, you have a smart TV... You get the gist.

In combination with biometrics and perimeter sensing features, your ring is your key to the house, to the car, to your office building, etc. It can activate your smart home or smart office setup. It also powers your smart speaker. You can pay with just the ring. You can link it to your AR/VR device and it's all powered up.

The devices you link to your ring don't need to be powerhouses themselves. They can just be like "dumb terminals" of varying forms and sizes. Your I/O to interface with the ring. This makes them cheaper and easier to dispose. They don't have all the electronics. They just need the minimum, enough to communicate with your ring. For watch, phone, tablet or laptop forms, battery would last longer between charges. In fact, it is likely that whatever you buy can last you many, many years before you'll even need to replace them.

This imagination is not far fetched. We have PC components built today using nano-technology. We have new materials like graphene and silicene being developed and explored. We have networks promising speeds in gigabits, terabits and petabits already. It's just a matter of time for all these nano-scale components to be put together to something as small as a ring, yet powerful enough to be a computing powerhouse. With a ring powered by an OS that can render the appropriate UI/UX to the I/O devices it is linked to, your ring is all the PC you'll need to power your digital life.
