Abstract: An ergonomic computer keyboard which integrates conventional keyboard features to form a Multi-Dexterous Keyboard (MDK) system designed to minimize Repetitive Stress Injuries. Specific emphasis is placed on the general and simultaneous utilization by either a single or dual handed, full or limited dexterity, and right and left oriented keyboard user. The ergonomic computer keyboard system is described as a solid and/or split contoured keyboard with centralized composite keys disposed thereon to reduce finger reach within one-hand span. Language characteristics are statistically extrapolated and arranged based on the most used letters or groups of letters in the form of digraphs (coupled letters) and trigraphs (tripled letters, etc.) for efficient utilization of the keyboard via either a dual or single handed user. A special partition of the keyboard provides numerous ergonomic arrangements with simultaneous use as either a Left-Hand-Side (LHS) or Right-Hand-Side computer keyboard module.
