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.

Matias Half Keyboard vs. Alternative One-Handed Solutions

Left Hand or Right Hand? How to Choose

The Matias Half Keyboard works with either your left or right hand—you choose which hand to use based on your needs:

• Left-hand typing: Best if your right hand is injured, recovering, or needs to stay on the mouse full-time. The keyboard sits on the left side of your workspace.
• Right-hand typing: Best if your left hand is injured, recovering, or needs to stay on the mouse. The keyboard sits on the right side of your workspace.
• Switching between hands: You can switch which hand you use at any time—the mirror mode works identically for both hands.

How mirror mode works: When you hold down the spacebar, the keyboard mirrors to the opposite side. For example, if you're typing with your left hand and need to type the letter "P" (normally on the right side), you hold space and press "Q" (the mirrored position). Your brain adapts to this pattern within minutes—most users are typing full sentences within the first hour.

Desk setup tip: Position the Half Keyboard directly in front of your typing hand, with your mouse on the opposite side. The compact 5.75\" width means both devices fit comfortably within arm's reach.

The Science: Why Mirror Mode Works Better Than Learning a New Layout

When you lose the use of one hand, traditional solutions force you to learn an entirely new keyboard layout—a process that requires rebuilding years of muscle memory and can take 3–6 months to reach proficiency. This extended retraining period delays return to work, reduces productivity, and causes frustration during recovery. The Matias Half Keyboard's patented mirror mode leverages spatial memory transfer—a neurological phenomenon where your brain automatically maps known patterns to mirrored positions. Research in motor learning shows that mirrored movements require minimal cognitive load because the brain recognizes the spatial relationship between original and mirrored positions. When you hold the spacebar and press "Q" to type "P," your brain doesn't need to memorize a new key location—it intuitively understands the mirror relationship. Occupational therapy studies demonstrate that stroke survivors and injury patients achieve 60–80% of their original typing speed within the first week using mirror mode keyboards, compared to 20–30% using alternative layouts. Physical therapists prescribe the Half Keyboard because it eliminates the cognitive burden of relearning, allowing patients to focus mental energy on physical recovery instead of keyboard memorization. The result: faster return to independence, maintained professional productivity, and measurably lower frustration during rehabilitation.
