Motor Disability
User with limited finger dexterity
A person with limited hand mobility could use ERICK with a gaming controller's analog sticks, avoiding the need to precisely tap dozens of small on-screen keys. The two large directional targets require only broad movements.
Color Vision Deficiency
User with deuteranopia (green-blind)
A person with deuteranopia could switch to the dedicated green-blind palette, where all 8 dial segments use colors chosen to remain distinguishable without red-green discrimination.
Dyslexia
User who struggles with standard fonts
A person with dyslexia could enable the OpenDyslexic font option so that all keyboard labels use weighted, asymmetric letterforms that reduce letter-swapping confusion during typing.
Left-Handed User
Left-hand dominant typist
A left-handed person could enable left-handed mode to mirror the dial layout, placing the primary character-group selector under their dominant thumb for more natural input.
Console / TV User
Typing on a TV or gaming console
A person using a smart TV or gaming console could connect a standard gamepad and type with ERICK's dual-stick chord system - far faster and more comfortable than navigating an on-screen grid keyboard with a D-pad.
Repetitive Strain Injury
User seeking ergonomic alternatives
A person experiencing RSI symptoms could benefit from ERICK's equal-effort character input, where every letter requires the same two broad movements - eliminating the uneven finger stretching that aggravates strain injuries on traditional keyboards.
One-Handed User
User with temporary or permanent single-hand use
A person with a broken arm or one-hand mobility could enable One-Handed mode, locking the left dial direction and typing entirely with the right thumb. No complex accessibility switches needed - just one toggle in settings.
Privacy-Conscious User
User who avoids data-collecting keyboards
A privacy-focused user could switch to ERICK knowing that no keystrokes, passwords, or personal data are ever logged, transmitted, or shared - the app runs fully offline with zero network permissions and is source available for verification.
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.
