1. A method for processing dual input from a single finger on a device having a touch panel, the method comprising:
- passively obtaining, from a preliminary touch on the touch panel to unlock the device, dimensions of a preliminary touch of a particular user;
determining, based on the dimensions of the preliminary touch, a touch baseline for dimensions of a standard tap of the particular user;
detecting a touch on the touch panel;
determining a touch pattern of the touch;
identifying the touch pattern as a standard tap from a first portion of the finger when the touch pattern corresponds to the touch baseline for the particular user;
identifying the touch pattern as a full tap from a second portion of the finger when the touch pattern is of a second surface area, larger than the touch baseline for the particular user;
generating a command signal based on the identifying the touch pattern as one of the standard tap or the full tap; and
performing an action based on the command signal.

Abstract
A method performed by a device having a touch panel may include detecting a touch on the touch panel, determining a dimension of the touch, identifying the touch as a standard tap or a full tap based on the dimension of the touch, and generating a command signal based on the identifying of the touch as the standard tap or the full tap.

7. A device comprising:
-
a display to display information; a touch panel to identify sizes and dimensions of touches on the touch panel; and a processor configured to; passively obtain, from a pass code entry operation on the touch panel to unlock the device, dimensions of a preliminary touch of a particular individual user; determine, based on the dimensions of the preliminary touch, a touch baseline for dimensions of a standard tap of the particular individual user; detect a touch on the touch panel, determine a surface area and a symmetry for a touch pattern corresponding to the touch from a finger of the particular individual user, identify, based on the touch baseline and the surface area and the symmetry for the touch pattern, the touch as a standard tap from a first portion of the finger or a full tap from a second portion of the finger, generate a command signal based on the identifying of the touch as the standard tap or the full tap, and alter the display based on the command signal. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A non-transitory computer-readable memory comprising computer-executable instructions, the computer-readable memory comprising one or more instructions for:
-
obtaining, from a preliminary touch on a touch panel to unlock a device, dimensions of a preliminary touch of a particular user, from a first portion of a finger; determining, based on the dimensions of the preliminary touch, a touch baseline for dimensions of a standard tap of the particular user; detecting a touch, from the finger, on the touch panel; determining a dimension of the touch; identifying a type of the touch as being from the first portion of the finger or a second portion of the finger based on the dimension of the touch and the touch baseline; identifying coordinates of the touch on the touch panel; associating the coordinates of the touch with an image displayed on a display of the device; and generating a command signal based on the type of the touch and the coordinates of the touch associated with the image displayed on the display.
