Input precision method for minimizing erroneous entries stemming from instability of a mobile device using an accelerometer and apparatus to detect a shake and apparatus and computer program thereof

摘要

A method of correcting an error in user input is described. The method includes monitoring for an occurrence of a shake in a user equipment, detecting a shake, comparing the detected shake with a threshold value, evaluating characters within a pre-determined distance of a character entered by the user during the shake, selecting a replacement character from the evaluated characters and replacing the entered character with the replacement character.

主权项

1. A user equipment comprising:
a transceiver for communicating data; a memory for storing the data; a sensor for detecting unintended movement of the user equipment, the movement being caused by factors external to the user equipment; a graphical user interface with a virtual onscreen keyboard; and a processor for:
evaluating the detected unintended movement;evaluating characters within a distance of a character entered by a user via the virtual onscreen keyboard during the detected unintended movement;selecting a replacement character from the evaluated characters; andreplacing the entered character with the replacement character, wherein the distance is variable and based on a magnitude of the detected unintended movement or a number of a plurality of detected unintended movements.
