1. A system for facilitating operations for text entry, the system comprising: a directional input tool having a mapping between different actual radial directions and different text characters, said directional input tool configured to use for sequentially pointing in an intended radial direction toward intended characters of at least part of an intended word; a determining processor configured for determining angular similarity between each actual pointing direction and radial directions of different characters in the mapping, for using the determined angular similarity to compute different possible combinations of intended characters that could form the intended word, and for presenting a list of potential matching words, where the presentation favors potential matching words according to factors including an aggregate angular similarity of constituent characters of a potential matching word to the actual pointing directions; a selecting processor for selecting the intended word from the list; and a displaying processor for displaying the selected word in a human-readable message composition display area.
