    • 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.
    • 电子设备包括多点触摸屏和密码输入系统。 多点触摸屏可以检测用户输入的序列,每个用户输入都涉及到其中的至少一个点。 密码输入系统包括确定单元,存储单元,索引单元和输出单元。 确定单元可以对用户输入的触摸点的数量进行计数。 存储单元存储字符数据库,该字符数据库包括多个触摸点的集合和相应的机器可读字符的集合。 索引单元可以查找字符数据库中用户输入的匹配机器可读字符。 输出单元可以作为密码顺序地输出匹配的机器可读字符。
