Method for unlocking an electronic device
An electronic device including a processing unit and a gesture input device connected with the processing unit, wherein the gesture input device is operable to detect an input gesture to initiate password entry during a software locked state. The electronic device further includes a display, wherein the processing unit is operable to randomly assign a predefined set of input gestures to a predefined set of password symbols, the display is operable to show an enter password screen showing the randomly assigned set of input gestures corresponding to the set of password symbols, the display is operable to show the randomly assigned predefined set of input gestures adjacent to the predefined set of password symbols, and the assigned set of input gestures correspond to the set of password symbols until the password entry is reinitiated.
1 . An electronic device, comprising:
a processing unit;
a gesture input device connected with the processing unit, wherein the gesture input device is operable to detect an input gesture to initiate password entry during a software locked state; and
a display;
wherein the processing unit is operable to randomly assign a predefined set of input gestures to a predefined set of password symbols, and
wherein the display is operable to show an enter password screen showing the randomly assigned set of input gestures corresponding to the set of password symbols, wherein the display is operable to show the randomly assigned predefined set of input gestures adjacent to the predefined set of password symbols, and wherein the assigned set of input gestures correspond to the set of password symbols until the password entry is reinitiated.
