| 摘要 |
The present invention relates to a method and a device for providing feedback on input of data. A processor (111) receives characters of the data repeatedly (s52), generates a feedback output from the received characters and a feedback output generated in advance (s55-s56), and outputs the feedback output (s57). Preferably, the processor (111) is included in the device that further comprises a user interface (113), through which the data is received. The feedback output is an image generated from at least one of geometric shapes, colors, 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. When data is a password, the starting output is preferably generated from user-related data. |
