Losing the Use of One Hand Shouldn't Mean Losing Your Productivity

Trusted by Fortune 500 accessibility programs and recommended by occupational therapists for stroke recovery, injury rehabilitation, and one-handed professionals. If you're struggling to type with one hand using a standard keyboard — hunting and pecking at half-speed, or facing months of retraining on a specialized layout — the Matias Half Keyboard lets you type at full speed immediately, using the same QWERTY layout you already know.

At Ask Ergo Works, our certified ergonomic specialists have 30+ years of experience recommending the right accessibility tools for clients in healthcare, rehabilitation, corporate, and government settings. The Matias Half Keyboard is one of the most clinically validated one-handed typing solutions available.

Why One-Handed Users Choose the Matias Half Keyboard

• Type at full speed instantly with zero retraining — patented mirroring technology lets you type all keys using just your left or right hand; no new layout to learn, no muscle memory to rebuild
• Mirror mode activates with the spacebar — hold space to access the opposite side of the keyboard; your brain adapts in minutes, not months
• Ultra-compact footprint saves desk space — at just 5.75" × 3.15", it's 60% smaller than a full keyboard; perfect for tight workspaces or one-handed mouse users
• Frees your other hand for mouse, phone, or tools — CAD designers, traders, and gamers use it to keep one hand on the mouse at all times
• Mechanical key feel with quiet operation — Matias Quiet Click switches deliver tactile feedback and durability (50 million keystrokes) without disturbing coworkers or family
• Mac + PC compatible out of the box — hardware switch toggles between operating systems; works with Windows, macOS, Linux, Chrome OS
• Built for accessibility and recovery — prescribed by occupational therapists for stroke survivors, amputees, RSI sufferers, and anyone with temporary or permanent one-hand use

What Customers Are Saying

"After my stroke, I thought my career as a programmer was over. The Half Keyboard let me get back to full typing speed in less than a week. My OT recommended Ask Ergo Works and I'm so glad she did."

"I'm a CAD designer and keeping my right hand on the mouse is non-negotiable. This keyboard changed my workflow completely — I can type every shortcut without ever lifting my hand off the mouse."

"We've ordered 12 of these for our rehabilitation center. The mirror mode concept is brilliant — patients adapt faster than any other one-handed solution we've tried."

Frequently Asked Questions

How long does it take to learn mirror mode?

Most users reach comfortable typing speed within 1–2 hours of practice, and near-full speed within a few days. Because mirror mode uses the same QWERTY layout you already know, your brain transfers existing muscle memory rather than building new patterns from scratch — a fundamentally different (and faster) learning curve than alternative one-handed layouts.

Is this keyboard for left-handed or right-handed users?

Both. The left half of the keyboard is always present; mirror mode (activated by holding the spacebar) gives you access to the right-side keys. Right-handed users type normally on the left half and use mirror mode for right-side characters. Left-handed users can use the keyboard in reverse orientation.

Will this work with my Mac or PC?

Yes — a hardware toggle switch on the keyboard switches between Mac and PC modes. Compatible with Windows, macOS, Linux, and Chrome OS with no drivers required.

Is this keyboard good for stroke recovery?

Yes — the Matias Half Keyboard is one of the most widely recommended keyboards for stroke survivors. Because it uses the same QWERTY layout with mirror mode rather than a completely new layout, patients can return to productive typing far faster than with alternative solutions. It is prescribed by occupational therapists in rehabilitation centers and hospital programs nationwide. If you need documentation for insurance or workplace accommodation, our certified ergonomic specialists can help.

Is this suitable for post-surgical recovery or temporary one-hand use?

Absolutely. Many users adopt the Half Keyboard temporarily after hand, wrist, or arm surgery and find they can maintain full work productivity throughout recovery. The zero-retraining requirement makes it practical even for short-term use.

Is this keyboard good for RSI or carpal tunnel syndrome?

Yes — users with RSI, carpal tunnel, or repetitive strain injuries often use the Half Keyboard to rest the affected hand while keeping the other hand fully productive. If you're managing RSI alongside other ergonomic concerns, we offer ergonomic consulting services to assess your complete setup.

How does this compare to the Matias Half-QWERTY Pro?

The standard Half Keyboard (HK101) is the classic wired USB version — reliable, widely prescribed, and the most clinically validated option. The Half-QWERTY Pro adds additional features for power users. If you're unsure which is right for your situation, our ergonomic specialists can help you choose based on your specific use case and recovery goals.

Is this prescribed by occupational therapists?

Yes. The Matias Half Keyboard is widely prescribed by occupational therapists for stroke recovery, upper limb amputation, and RSI rehabilitation. It is used in Fortune 500 accessibility programs and rehabilitation centers. Contact our certified ergonomic specialists for documentation support for insurance or ADA accommodation purposes.

Can I use this for gaming?

Yes — the compact footprint and one-handed design make it popular among gamers who want full keyboard access while keeping the other hand on the mouse. The Matias Quiet Click switches provide tactile feedback suitable for gaming use.

What if I need help setting it up or justifying it for a workplace accommodation?

Our certified ergonomic specialists provide professional assessments, documentation support for ADA accommodations, and guidance on integrating the Half Keyboard into your complete workstation setup. We work with HR teams, occupational therapists, and facilities managers on accessibility programs.

Is this available for bulk or institutional orders?

Yes — we supply the Matias Half Keyboard to hospitals, rehabilitation centers, government agencies, and corporate accessibility programs. Contact us for volume pricing and program support.

What is the return policy?

The Matias Half Keyboard comes with a 30-day satisfaction guarantee and a 2-year manufacturer warranty. If you're not fully satisfied, contact us and we'll make it right.
