Directional input system with automatic correction
First Claim
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.

Abstract
A system associated with a text entry application, such as email or instant messaging, comprises an optional onscreen representation of a circular keyboard, a list of potential linguistic object matches, and a message area where the selected words are entered. The circular keyboard is manipulated via a hardware joystick or game-pad with analog joystick or omni-directional rocker switch built therein. The user points the joystick in the general direction of the desired letter, and then continues pointing roughly to each letter in the desired word. Once all letters have been roughly selected, buttons are used to select a specific word from the list of potential matches and send the selected word to the message area.

2. A computer-implemented method for facilitating operations for text entry, the method comprising:
-
by using a directional input tool having a mapping between different actual radial directions and different text characters, sequentially pointing in an intended radial direction toward intended characters of at least part of an intended word; determining, by a determining processor, angular similarity between each actual pointing direction and radial directions of different characters in the mapping, using the determined angular similarity to compute different possible combinations of intended characters that could form the intended word, and 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; selecting, by a selecting processor, the intended word from the list; and displaying, by a displaying processor, the selected word in a human-readable message composition display area.

3. A computer-readable storage medium 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 text characters, sequentially pointing in an intended radial direction toward intended characters of at least part of an intended word; determining angular similarity between each actual pointing direction and radial directions of different characters in the mapping, using the determined angular similarity to compute different possible combinations of intended characters that could form the intended word, and 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; selecting the intended word from the list; and displaying the selected word in a human-readable message composition display area.
