TOUCH-SCREEN BASED PASSWORD INPUT SYSTEM AND ELECTRONIC DEVICE HAVING SAME |
摘要 |
An electronic device includes multi-touch screen and a password input system. The multi-touch screen can detect a sequence of user inputs, each of which involves tapping at least one point thereof. The password input system includes a determining unit, a storing unit, an indexing unit, and an outputting unit. The determining unit can count the numbers of touch point(s) of the user inputs. The storing unit stores a character database which includes a collection of numbers of touch point(s) and a collection of corresponding machine-readable characters. The indexing unit can look up matching machine-readable characters for the user inputs in the character database. The outputting unit can output the matching machine-readable characters sequentially as a password.
