AI Technical Summary

Problems solved by technology

For example, users may find it difficult to accurately hit the correct virtual keys, especially on small virtual keyboards
In addition, since the user cannot feel the virtual keys of the virtual keyboard, the user's fingers may slip out of the virtual keyboard, resulting in a decrease in typing accuracy

Embodiment Construction

[0025] The figures illustrate examples. Elements indicated by reference numerals in the drawings correspond to elements indicated by the same reference numerals in the following description. In the figures, stacked elements in the figures indicate the presence of one or more similar elements. In this disclosure, an element having a name beginning with an ordinal word (eg, "first," "second," "third," etc.) does not necessarily imply that the elements have a particular order. Rather, such ordinal numbers may merely be used to refer to different elements of the same or similar type.

[0026] As described in detail below, a computing device may be operatively coupled to a presence-sensitive surface associated with a virtual keyboard. The virtual keyboard may include a set of virtual keys. In some examples, the virtual keyboard may include virtual keys corresponding to letters or characters. For example, a first virtual key may correspond to the letter "q", a second virtual key...

Abstract

A computing device is operatively coupled to a presence-sensitive surface associated with the virtual keyboard. The computing device receives an indication of gesture input on a portion of a presence-sensitive surface associated with the virtual keyboard. In response, the computing device defines a series of input points that represent a path for gesture input across the virtual keyboard. Additionally, the computing device defines anchor points for virtual keys of the virtual keyboard. The computing device then determines a distance score for the anchor point word based on a distance on the presence-sensitive surface between the input point and the anchor point. The computing device identifies a word corresponding to the gesture input based on the distance score for the anchor point.

Description

Background technique [0001] Traditionally, users provide text input to computing devices via physical keyboards. A physical keyboard includes physical, depressible buttons that correspond to different characters and functions. [0002] However, many types of modern computing devices do not have physical keyboards. For example, many mobile computing devices, such as smart phones and tablet computers, do not have physical keyboards. Alternatively, a computing device may include a presence-sensitive display (eg, a touch screen) that displays a "virtual" keyboard. The virtual keyboard may include virtual keys corresponding to different characters and functions. Each virtual key may correspond to a different area of ​​the display where there is a sensitivity. [0003] In some cases, a user may provide text input to a computing device by tapping the user's finger or stylus on virtual keys of a virtual keyboard displayed by the computing device. Thus, to enter the word "text," t...
