Method and User Interface for Entering Characters

Abstract

A direction of movement indicated by an input device is detected when a start of a character entering function has been detected. The entered character is shown on the character area on a display, towards which character area the direction of movement indicated by the input device is proceeding. The termination of the character entering function is detected, and the character towards whose character area the direction of movement was last detected to proceed as the character to be entered next is detected.

AI Technical Summary

Benefits of technology

"The invention provides a method and user interface for entering characters in an electronic device. The method involves predetermining a given character area on the display for each character, detecting the start of a character entering function, showing the character of the character area on the display towards which the direction of movement indicated by the input device is proceeding, detecting the termination of the character entering function, and interpreting the character towards whose character area the direction of movement was last detected to proceed as the character to be entered next. The user interface includes a display for showing the entered characters and an input device for giving control commands for entering the characters. The method and user interface provide fast, easy, and accurate entry of characters."

Problems solved by technology

A special problem in the usage of an electronic device is the entering of text.

Eventually the keypad used in electronic devices, such as a character keypad, becomes impracticable, because it is difficult for the user of the device to press extremely small keys.

The current text entry systems, such as handwriting or speech recognition systems, are often slow and error prone.

Also in the handwriting systems the area reserved on the touch screen for writing characters is small, which makes it hard to write in said area in a moving vehicle, for example.

If the selection of the characters is conducted by sliding a pen over the desired character visible on the touch screen, it is difficult to hit the correct character when, for example, the writer's hand shakes in a rush hour bus.
