Claim #1

Now, before trying to answer, I want to note 3 things directly from the patent: 

1. "There is a need for more efficient, user-friendly procedures for unlocking such devices, touch screens, and/or applications" 
2. For "transitioning such devices, touch screens, and/or applications between user interface stages"
3.  "There is a need for sensory feedback to the user regarding progress towards the satisfaction of a user input condition that is required for the transition to occur" 

I took all of these to basically claim that their main objective is to have a smooth transition on the device that is user friendly and greatly helps revisit the use of the interface. These are what I will refer to as the patent's "objective"

Let's revisit the claim... 
1. A method of unlocking a hand-held electronic device, the device including a touch-sensitive display, the method comprising:

detecting a contact with the touch-sensitive display at a first predefined location corresponding to an unlock image;

continuously moving the unlock image on the touch-sensitive display in accordance with movement of the contact while continuous contact with the touch screen is maintained, wherein the unlock image is a graphical, interactive user-interface object with which a user interacts in order to unlock the device; and

unlocking the hand-held electronic device if the moving the unlock image on the touch-sensitive display results in movement of the unlock image from the first predefined location to a predefined unlock region on the touch-sensitive display.

The goal of the claim is to get to the objective! 

1. For user friendly procedures: 
1. "detecting a contact with the touch-sensitive display" 
• This is explains the context and makes it user friendly in the sense that they can understand it and directly how to use it. 
2. "interactive user-interfact object with which a user interacts in order to unlock the device" 
• This explains the purpose and what the user is going to be doing. 
2. For transitioning between user interface stages: 
1. "results in movement of the unlock image from the first predefined location to a predefined unlock region" 
• This explains the procedure in which you can transition between the "locked" and "unlocked" stages. 
3. For sensory feedback:
1. "continuously moving the unlock image on the touch-sensitive display in accordance with movement of the contact while continuous contact on the touch screen is maintained" 
• This explains instructions on how to unlock and use the device.
