A METHOD AND A DEVICE FOR READING OUT KEYBOARD KEYS |
摘要 |
A method and a device for reading out keys of a keyboard. The read-out is realised by randomly generating a scanning pattern comprising for each row and column a read-out value to be applied on the rows and columns. The scanning pattern is preferably changed after having been applied to the keys. After application of the randomly generated pattern, the verification routine is applied in order to identify the selected keys.
