Claim:
A computer-implemented method for executing an action on a mobile device, comprising: outputting, at a touch screen of the mobile device, a lock screen view configured to prevent unauthorized or inadvertent access to the mobile device; while the lock screen view is displayed at the touch screen: detecting, at the touch screen, a touch gesture having a pre-defined shape, wherein the touch gesture is entered by a user at any position on the touch screen, the touch gesture being of any size relative to the pre-defined shape; and in response to detecting the touch gesture, executing, by the mobile device a particular action determined, at least in part, on the pre-defined shape, whereby detection of the touch gesture causes the particular action to execute while the lock screen view is displayed at the touch screen; whereby executing the particular action while the lock screen view is displayed at the touch screen and in response to the touch gesture being entered at any position on the touch screen prevents inadvertent access while the mobile device is obscured from view.
