Abstract: A text input system is described for inputting text to a computing device. The text input system has a memory storing a composing region comprising a plurality of text items selected by a user for potential input into the computing device. The text input system has a composing region updater which detects one of the plurality of text items as being a designated symbol. The composing region updater is configured to detect a corrective action acting to correct associated text associated with the selected text items and, when the corrective action is detected, to return the plurality of text items including the designated symbol to the composing region.

Abstract: A text input system is described for inputting text to a computing device. The text input system has a memory storing first evidence comprising text selected by a user for input to the computing device in a first attempt by a user to input intended text. The memory stores second evidence comprising either information about text deleted by the user or text selected by the user in a second attempt at inputting the intended text. The text input system has an input model configured to combine at least the first and second evidence to produce combined evidence; and a text predictor configured to take the combined evidence as input and use the combined evidence to compute a plurality of predicted text items for input to the computing device.
