Directional input system with automatic correction

A computer-implemented method for facilitating operations for sub-word component entry, the method comprising:

• by using a directional input tool having a mapping between different actual radial directions and different sub-word components, sequentially pointing in an intended radial direction toward intended sub-word components of at least part of an intended linguistic object;
• determining, by a determining processor, angular similarity between each actual pointing direction and radial directions of different sub-word components in the mapping, using the determined angular similarity to compute different possible combinations of intended sub-word components that could form the intended linguistic object, and presenting a list of potential matching objects, where the presentation favors potential matching linguistic objects according to factors including an aggregate angular similarity of constituent sub-word components of a potential matching linguistic object to the actual pointing directions;
• selecting, by a selecting processor, the intended linguistic object from the list;
• and
• displaying, by a displaying processor, the selected linguistic object in a human-readable message composition display area.

A computer-readable storage medium for facilitating operations for sub-word component entry storing instructions which, when executed by one or more processors, cause the one or more processors to carry out the steps of:

• by using a directional input tool having a mapping between different actual radial directions and different sub-word components, sequentially pointing in an intended radial direction toward intended sub-word components of at least part of an intended linguistic object;
• determining, by a determining processor, angular similarity between each actual pointing direction and radial directions of different sub-word components in the mapping, using the determined angular similarity to compute different possible combinations of intended sub-word components that could form the intended linguistic object, and presenting a list of potential matching objects, where the presentation favors potential matching linguistic objects according to factors including an aggregate angular similarity of constituent sub-word components of a potential matching linguistic object to the actual pointing directions;
• selecting, by a selecting processor, the intended linguistic object from the list;
• and
• displaying, by a displaying processor, the selected linguistic object in a human-readable message composition display area.
