Finger Mapping Reference

Left Hand: LP (Pinky) – Q, A, Z.
Left Hand: LR (Ring) – W, S, X.
Left Hand: LM (Middle) – E, D, C.
Left Hand: LI (Index) – R, T, F, G, V, B.
Right Hand: RI (Index) – Y, U, H, J, N, M.
Right Hand: RM (Middle) – I, K.
Right Hand: RR (Ring) – O, L.
Right Hand: RP (Pinky) – P.

Finger assignments shown here are for QWERTY layout; other layouts use the same finger positions for different letters.

Distance Calculation Reference

Distance is measured on a staggered grid where adjacent keys horizontally or vertically are 1 unit apart, and the top (row 0) and bottom (row 2) rows are offset by 0.5 units horizontally relative to the home row (row 1). For each non-home key press, compute the straight-line (Euclidean) distance to the finger’s home key:

distance = sqrt((row2 - row1)^2 + (col2 - col1)^2)

These distances are summed per finger to give the total travel effort. Diagonal moves are longer than purely horizontal or vertical moves since both row and column differences contribute.
