Input device

摘要

In an input device for inputting characters on a user interface by handwriting, the movement of an input unit, in particular a finger of a user, is detected and converted to an input pattern corresponding to the detected movement. The input pattern is compared with stored characters of a character set, and if the input pattern sufficiently matches one of the stored characters, the character is selected. During the input, the user receives acoustic feedback about the input process, such that the acoustic feedback signal is output in a constant manner outside a defined edge area of the user interface and is output in an incremental or continuous manner at a decreasing distance from the edge in a defined edge area of the user interface.

主权项

1. An input device for handwritten input of characters on a user interface, comprising:
a detector configured to detect a movement of an input unit; a converter configured to convert the detected movement into an input pattern; a comparison unit configured to compare the input pattern with stored characters; a selecting unit configured to select one of the stored characters on the basis of the comparison of the comparison unit; and a generating and outputting unit configured to generate and convert an acoustic feedback signal during the handwritten input, wherein outside a defined edge region of the user interface, the acoustic feedback signal is output as a first, and constant, acoustic feedback signal, and in a defined edge region of the user interface, the acoustic output signal is output as a second acoustic feedback signal that is modified incrementally or continuously as the distance to an edge of the user interface decreases, the second acoustic feedback signal being different from the first feedback signal, and wherein the defined edge region is dynamically variable so as to adapt a size of the defined edge region to writing behavior of a particular user of the user interface.
