Oligodactyly

A congenital condition in which a person is born with fewer than the typical number of fingers or toes. The condition varies widely in presentation — some individuals may have fewer digits on one hand or both, and the remaining digits may differ in size, strength, or dexterity. For computer access, oligodactyly can make standard keyboards challenging due to difficulty reaching keys, pressing key combinations, and navigating the space bar, often requiring adaptive keyboards, key remapping, or alternative input devices.
