Adaptive determination of information display

Abstract

A method for operating a list in a mobile terminal is disclosed. An example method includes displaying a first set of items from an item list in the mobile terminal, changing the item list based on a received command, determining a direction of most recent movement in the item list before the receiving of the command, determining items from the item list to display according to the determined direction and the change of the item list, and displaying the determined items from the item list.

What is claimed is: 
     
       1. A method for manipulating a list in a mobile terminal, the method comprising:
 scrolling an item list in response to a first received command;   displaying a first set of items from the item list in the mobile terminal;   changing the item list based on a second received command to perform at least one of adding a new item to the item list or deleting an item from the item list;   determining, subsequent to the second received command, a previous scroll direction of the item list, the scroll direction in response to receipt of the first command;   determining items from the item list to display based on the determined previous scroll direction and the change of the item list; and   displaying the determined items from the item list.   
     
     
       2. The method of  claim 1 , wherein the displaying of the determined items list from the item list comprises scrolling the item list according to the determined previous direction of the scrolling of the item list and according to the second received command to change the item list. 
     
     
       3. The method of  claim 1 , wherein the determining of the items from the item list to display comprises:
 determining, if the second received command is to delete an item from the item list and if the determined previous direction is a downward direction, an item from the item list to display that is subsequent to the deleted item and is not displayed in the first set of items; and   determining, if the second received command is to delete the item from the item list and if the determined previous direction is an upward direction, an item from the list of items to display that is prior to the deleted item and is not displayed in the first set of items.   
     
     
       4. The method of  claim 3 , wherein the determining of the items from the item list to display comprises:
 determining, if the second received command is to add an item to the item list and if the determined previous direction is the downward direction, an item from the first set of items to remove from the display that is prior to the added item; and   determining, if the second received command is to add the item to the item list and if the determined previous direction is the upward direction, an item from the first set of items to remove from the display that is subsequent to the added item.   
     
     
       5. The method of  claim 3 , further comprising:
 determining, if the direction of the scrolling cannot be determined and if the second received command is to add the item to the item list, content from the first set of items to remove from the display that is prior to and subsequent to the added item; and   determining, if the direction of the scrolling cannot be determined and if the second received command is to delete the item from the item list, content from the item list to display that is prior to and subsequent to the deleted item.   
     
     
       6. The method of  claim 1 , wherein the direction of the scrolling is input when a most recent input exceeds a threshold value that represents scrolling in the corresponding direction. 
     
     
       7. The method of  claim 1 , wherein the determining of the previous direction of the scrolling in the item list further comprises:
 determining, based on historical data, a historical direction of scrolling after the changing of the item list; and   setting, if the determined previous direction does not match the historical data of scrolling, the historical data of scrolling as the determined previous direction.   
     
     
       8. A method for manipulating a list in a mobile terminal, the method comprising:
 displaying a first set of items from an item list in the mobile terminal;   changing the item list based on a received command;   determining a direction of a scrolling of the item list that occurred before receipt of the command;   determining items from the item list to display based on the determined direction and the change of the item list; and   displaying the determined items from the item list;   wherein the determining of the items from the item list to display comprises:
 determining, if the command is to delete an item from the item list and if the determined scrolling direction is a downward direction, an item from the item list to display that is subsequent to the deleted item and is not displayed in the first set of items; and 
 determining, if the command is to delete the item from the item list and if the determined scrolling direction is an upward direction, an item from the list of items to display that is prior to the deleted item and is not displayed in the first set of items.
