Colorblind support
ERICK uses color to distinguish the 8 directional segments on each dial. For users with color vision deficiency, six carefully designed palettes ensure every direction remains visually distinguishable. You can also create a fully custom palette.
Left-handed mode
Toggle left-handed mode to swap the two dials entirely. Left-hand dominant users get a mirrored layout where the primary selection dial sits on their strong side, reducing fatigue and improving accuracy.
Dyslexia-friendly fonts
Enable the OpenDyslexic font option in ERICK's settings. This typeface uses weighted letter bottoms and unique shapes to reduce visual confusion, making labels and text previews easier to read.
Motor accessibility
ERICK replaces dozens of small keys with two large directional targets. Full physical controller support means users who cannot interact with touchscreens can still type comfortably using a gamepad's analog sticks.
Equal-effort input
Every character requires exactly two movements, one on each dial. There is no reaching, no stretching, and no hunting for keys. This consistent effort reduces repetitive strain and makes typing sustainable over longer sessions.
Word prediction and autocorrect
Always-on word suggestions reduce the number of chords needed per sentence. ERICK offers completions, spelling corrections, and next-word predictions, and every prediction runs fully offline with zero data collection.
One-handed typing mode
Enable One-Handed mode to type with a single thumb. Lock a direction on the left dial, then use only the right dial to select characters. This is one of three input modes, alongside Quick Type for speed and Steady Type for deliberate input.
Haptic feedback and typing sounds
Enable haptic vibration and typing sounds for sensory confirmation of each keystroke. Utility keys such as Backspace, Enter, and Shift produce a stronger pulse, while letter chords use a softer tap.
Research-informed design
ERICK is informed by research on chorded input, reduced finger travel, and alternative keyboard layouts. The strongest evidence supports the value of low-movement, ergonomic text entry. More specific claims, such as which layout is best for every user group, should be treated as promising design directions rather than settled fact.
