The invention concerns user entry of information into a system with an input device. A scheme is provided in which an entire word that a user wants to enter is predicted after the user enters a specific symbol, such as a space character. If the user presses an ambiguous key thereafter, rather than accept the prediction, the selection list is reordered. For example, a user enters the phrase “Lets run to school. Better yet, lets drive to “.””” After the user presses the space, after first entering the second occurrence of the word “to,” the system predicts that the user is going to enter the word “school” based on the context in which the user has entered that word in the past. Should the user enter an ambiguous key after the space, then a word list which contains the word “school” is reordered and other options are made available to the user. The invention can also make predictions on context, such as the person to whom the message is sent, the person writing the message, the day of the week, the time of the week, etc. Other embodiments of the invention contemplate anticipation of user actions, as well as words, such as a user action in connection with menu items, or a user action in connection with form filling.

The invention discloses a layout space streaming restoring method. The method comprises the steps of: acquiring three adjacent characters in a layout; calculating a character pitch between two adjacent characters, and calculating a difference value of the character pitches; if the difference value of the character pitches is smaller than a preset difference threshold value, not inserting a space; if the difference value of the character pitches is not smaller than the preset difference threshold value, calculating the sum of a right boundary value of the first character and a left boundary value of the second character to serve as a boundary value sum, and calculating the difference value of first character pitch and the boundary value sum to serve as a judgment value; and if the judgment value is larger than a word width value of the space character with same type of the first character, inserting the space behind the first character, otherwise, not inserting the space. Therefore, by calculating the blank space between two adjacent characters, a phenomenon whether the pitch is uniform due to the layout or is caused by the space character can be judged; if the difference value of the two character pitches is within the threshold value, the spacing is uniform, and the space is not required to be inserted; if the difference value is large, the space can be inserted after comparison and judgment; and therefore, when the spaces required by the layout is converted in a streaming mode, the required spaces can be increased by restoring the space, so that display of the layout is relatively accurate.

A method for processing a page character array finds links and creates link groups containing adjacent link characters. Adjacency of link characters is preferably defined as characters which are separated by any combination of no characters, blank space characters, line feed characters, or separator characters, such as vertical or horizontal separator bars or other separator characters. Once link groups have been defined, the method lays out each link group for display in an optimized form. Links are displayed as buttons. An optimized form of display includes centering all the buttons in a vertical list. Another optimized form of display includes laying out the link group as a rectangular matrix of buttons. According to another aspect, each of the links in a link group are logically mapped to a distinct user input, such as a key or voice command. The logical mapping aspect and optimized display aspect are optionally combined for certain types of hardware. For example, if keys are physically adjacent to any part of the display, the links are displayed near the keys, or in horizontal and / or vertical alignment with the keys, so that the key to which a link is mapped is apparent from its position on the display screen. As another example, the name of key or command to which a link is mapped is displayed within or beside the button containing the name of the link.
