APPARATUS AND METHOD FOR PROVIDING FEEDBACK ON INPUT DATA

摘要

A method and an apparatus for providing feedback on input of data. A processor (111) iteratively receives (S52) a character of the data and generates (S55; S56) a feedback output from the received character and a feedback output generated previously. The processor (111) also outputs (S57) the feedback output. The processor (111) preferably belongs to an apparatus that further comprises a user interface (113), through which the data is received. It is preferred that the feedback output is an image, preferably generated from at least one of geometric shapes, colours, rotations of the image and flips of the image. The feedback output for a first received character can be based on the first received character and a starting output and it is preferable that when the data are a password, the starting output is generated from user related data.
