Disclosed is a mechanism to improve the word completion function on current mobile devices. The invention incorporates motion sensing technology with vector-based type ahead functionality to enable the user to execute a specific motion in order to select among available word choices (or other options) presented on the screen of a mobile device. The choices are extracted from detected historic usage patterns.

Vector based type ahead using motion sensing mobile device for word entry

Auto-completion of texting on mobile devices rapidly increases the speed by which users can text and is a very popular function. There is still opportunity for improvement, however. Word completion on current mobile devices involves choosing a word or letter from the keyboard, some of which are very small and difficult for the user to manipulate choose the correct letter. To help with this problem, a mechanism for choosing words from a plurality of word choices by using directional motion sensing would be helpful.

There are several cases where prior art describes text or word completion using letter input from a keyboard device, but none of which reference using the vector- based or directional motion as the input method by which to select the appropriate word. Current approaches include:
• Data entry for personal computing devices: Describes a vector-based keyboard that changes based on possible letter choices. User input is via a pointing device of some sort. This does not use an accelerometer to detect the motion of a hand-held device as an input mechanism. [1]

• An idea similar to a pager or watch where letters can be entered by detecting tilt of device. This neither chooses words from commonly used word choices, nor teaches methods for expanding word choices using a scramble motion. [2]

The disclosed invention describes a mechanism for using motion sensing technology to select among available choices, as detected from historic usage patterns, presented on the screen of a mobile device. This invention uses the motion sensing technology available in many mobile devices as a new method to select from a set of available options displayed on the screen. This invention could be used for selecting multiple types of data, such as words that have been detected as likely choices through auto-complete.

The following describes an example of how this invention in a possible embodiment: (Figure 1)
