Embodiment Construction

[0011] Many devices receive text input from a user. Relatively large devices, such as desktop or laptop computers, often have full-size mechanical keyboards to receive text input. However, other devices may receive input through other mechanisms. Some of these mechanisms include multi-tap, predictive text, on-screen keyboards, and handwriting recognition.

[0012] For example, a wireless telephone may receive text input through a keypad using multi-tap or predictive text methods. For either of these methods, each key is assigned to represent a plurality of letters or symbols. With multi-tap, the user selects a specific letter or symbol by pressing the key a number of times in rapid succession (for example, if the "2" key on a keypad represents the letters A, B, and C, press the key twice Corresponds to option letter B). For predictive text systems such as T9, a specific sequence of keystrokes is associated with one or more words. If a sequence resolves to a single word, t...

Abstract

Text input may be recognized from a combination of keystroke information and handwriting gesture information. In one example, the touch screen displays an on-screen keyboard. The user then draws the character on the keyboard over the key representing the character. In this way, two types of information are provided that identify the character the user intends to enter: the particular drawing gesture provided by the user, and the location on the keyboard where the user drew that gesture. These two pieces of information can be used in conjunction to determine which character the user intended to enter, and may help to correctly interpret the input in situations where either the gesture or the keystroke information individually may have been ambiguous.

Description

Background technique [0001] When the use of a fully mechanical keyboard is not feasible or appropriate, there are various ways to enter text on the device. For example, wireless telephones typically allow users to enter text on keypads using a multi-tap method or using predictive text technology such as T9. Devices with touch screens can use handwriting recognition, or can provide an on-screen keyboard. Devices with microphones can provide speech-to-text capabilities. [0002] While these techniques may allow devices to receive text input, they may be suboptimal in certain situations. Entering text via these methods can be erroneous, slow to use, or have a steep learning curve. Contents of the invention [0003] The input of text can be performed by a combination of position and gesture. This combination provides the input system with two pieces of information about what text the user is attempting to enter, helping the input system to discern the user's intent with rela...
