Claim Text:
1. A method for unlocking an electronic device that has a touchscreen, the method comprising: detecting, by one or more processors, multiple simultaneous tactile inputs to a touchscreen on an electronic device, wherein the electronic device is initially in a locked state, and wherein a locked electronic device requires a user-provided unlock signal before allowing access to resources within the electronic device; determining, by one or more processors, a distance between most distant tactile inputs from the detected multiple simultaneous tactile inputs to the touchscreen, wherein the most distant tactile inputs are physically farther apart than any other two tactile inputs from the multiple simultaneous tactile inputs; calculating, by one or more processors, a relative position of other detected tactile inputs from the multiple simultaneous tactile inputs as measured from the most distant tactile inputs; and in response to the relative position of the other detected tactile inputs matching a stored positioning file for touchscreen tactile inputs, unlocking, by one or more processors, the electronic device, wherein the relative position of the other detected tactile inputs matches the stored positioning file for touchscreen tactile inputs independent of the distance between the most distant tactile inputs from the detected multiple simultaneous tactile inputs to the touchscreen.
