1. From “Small” to “Screenless” – Why Do We Need ARPC?

Over the past two decades, computers have kept getting smaller: desktop → laptop → tablet → mini PC. From the size of a desk down to a power bank. But here’s the catch: the host shrank, but the peripherals didn’t. You still need a screen, a keyboard, a mouse, and a power cord. A business trip means lugging around a backpack that feels like moving house.

ARPC takes a different approach: instead of making the host even smaller, it puts the screen on your face and merges the keyboard with the computer. The result? A full PC + a 120‑inch giant display, folded down to the size of a power bank.

2. What Exactly Is ARPC? Let’s Take It Apart

ARPC isn’t a single gadget – it’s a display unit + computing unit combo.

🕶️ Display: AR Glasses (AR40‑C / ARPC‑W)

Looks like slightly thicker sunglasses, weighing just 86–99g. Using BirdBath optical waveguide technology, it projects an equivalent 120‑inch virtual screen at about 3 meters away – roughly 2.7m wide × 1.5m tall. Resolution is Full HD 1080p at 60Hz, crisp enough for office work, design, and movies. Only the wearer can see the content – others just see translucent lenses. 0–600° myopia correction is built in, so no extra prescription lenses are needed.

⌨️ Computing: Foldable Keyboard Host (SPAEXI Four Series)

SPAEXI’s foldable keyboard host has formed a complete product matrix covering everything from AIoT to high‑performance computing:

领界 (Lǐngjiè)LingAR AMDAMD high‑performance processor (coming soon)High‑performance all‑rounder, professional multi‑tasking

Common features: Unfolds into a full‑size 65‑key keyboard (with touchpad); folds down to just 167×104×26mm – smaller than a pack of tissues. 8000mAh battery giving 2–3 hours of continuous use and 4–5 hours of standby. A single full‑featured USB‑C port handles power, video output, and data all at once. Weighs around 600g for the whole unit.

🔗 Connection

Simply plug the glasses into the keyboard host via a USB‑C cable – plug and play, zero latency. The glasses have no built‑in battery or processor; they draw all power and signal from the keyboard host – which is why they’re so light, with no heating or battery anxiety.

3. Why ARPC Changes the Game

Traditional mini PCs solve the problem of “a small host,” but users still have to carry a screen, keyboard, mouse, and power cord. ARPC solves the problem of miniaturizing the entire desktop setup – with just one USB‑C cable, connect to any display, and this foldable keyboard becomes a complete PC.

In the lineage of folding design, ARPC inherits the exploration of foldable forms that began with IBM’s ThinkPad 701 “Butterfly Keyboard” – but goes further by extending “folding” from the keyboard to the entire computer, creating a truly foldable, all‑in‑one computing device.

4. Who Is It For?

Frequent business travelers: Work efficiently on trains, planes, and in hotels without disturbing your neighbor.

Freelancers who value privacy: Handle sensitive documents in coffee shops or libraries without worry.

Programmers & designers: 120‑inch virtual desktop – code and design at a glance.

Students: Watch lectures, write papers, explore 3D models – and protect your eyes (virtual screen at 3‑meter distance).

Tech enthusiasts: Get a taste of the “future of computing” today.

5. Conclusion

ARPC isn’t meant to replace your desktop or laptop. It’s for those moments when you need extreme portability, a private big screen, and the ability to start working in seconds – things traditional devices can’t offer. You carry a pair of glasses and a foldable keyboard. But what you own is a private 120‑inch workstation. While others are still struggling to set up their laptops, hunting for power outlets, and worrying about screen‑peeping, you simply unfold your keyboard, put on your glasses, and open a mobile digital workshop right from your pocket.

This is ARPC – making spatial computing accessible, and putting warm technology in your pocket.
