Abstract
A list managing method and apparatus that manage a list of content in a portable terminal having a touch screen according to multi-touch signals are disclosed. The method includes: detecting multi-touch signals input to a list on a touch screen; determining whether the multi-touch signals are input for a period of time equal to or greater than an activation time period; designating, if the multi-touch signals are input within the activation time period, the entire list with a selection area for altering a structure of a list; identifying a gesture generated by the multi-touch signals; expanding or contracting the structure of the entire list according to the gesture; and displaying the altered structure of the entire list on the touch screen.
Claims16
A method for managing lists using multi-touch, comprising:
- detecting a multi-touch on a list displayed on a touch screen;
- identifying a gesture generated by the multi-touch;
- determining whether a selection area for altering a structure of the list is a particular portion of the list or the entire list, according to a comparison between a touch input time period for which the multi-touch is maintained following the detection of the multi-touch until the identification of the gesture and a preset activation time period;
- and
- displaying an altered structure of the list by altering the structure of the determined selection area of the list according to the gesture.
A method for managing lists using a multi-touch input device, comprising:
- displaying a list on a touch screen;
- detecting a multi-touch on the list;
- detecting a gesture generated by the multi-touch;
- determining whether a selection area for altering a structure of the list is a particular portion of the list or an entire list, according to a touch input time between the detection of the multi touch and the gesture;
- comparing the touch input time with a preset activation time period;
- designating, if the touch input time is less than the activation time period, the entire list as the selection area;
- designating, if the touch input time for a time period is equal to or greater than the activation time period, a particular portion of the list as the selection area;
- and
- displaying an altered structure of the list by altering the structure of the determined selection area of the list according to the gesture.
An apparatus for managing using multi touch processing, comprising:
- a display unit for displaying a list on a touch screen;
- and
- a controller configured to:
- detect a multi-touch on the displayed list;
- identifying a gesture generated by the multi-touch;
- determine whether a selection area for altering a structure of the list is a particular portion of the list or the entire list, according to a comparison between a touch input time period for which the multi-touch is maintained following the detection of the multi-touch until the identification of the gesture and a preset activation time period;
- and
- cause an altered structure of the list to be displayed by altering the structure of the determined selection area of the list according to the gesture.
