Abstract: A prompting method of an adjustable direction of a cursor for a portable electronic apparatus includes the follow steps: detecting a location of a cursor in a display, with the cursor indicating an indicated direction; determining whether any set direction corresponding to the location of the cursor is different from the indicated direction; and if any set direction corresponding to the location of the cursor is different from the indicated direction, displaying a directional adjustment prompting information for prompting at least one adjustable direction of the cursor corresponding to the location of the cursor.

Abstract: The invention provides an electronic device including a display unit, a touch sensing module and a processing unit. The display unit displays a user interface. The user interface includes a function-enabled area and a cursor. The touch sensing module is arranged to sense a touching object corresponding to the touch event of the cursor. The processing unit is arranged to implement the user interface. The processing unit further enables a function of the function-enabled area when the touch event corresponds to an event in which the cursor is dragged into the function-enabled area and remains in the function-enabled area by pressing for a first predetermined period.

Abstract: A method for displaying of a touch cursor is provided. The method is adapted to an electronic apparatus having a touch display unit. The touch display unit has a display area. The method includes the following steps. At least one first dimension boundary and at least one second dimension boundary are defined in the display area. A cursor, which has a pointing area and a touchable area, is displayed. When a touch event occurs in the touchable area, the cursor is correspondingly moved according to a touch coordinate of the touch event. When a reference point of the cursor passes two of the at least one first dimension boundary or two of the at least one second dimension boundary, the cursor is rotated for adjusting a relative position of the pointing area and the touchable area.

Abstract: A touch control method, adapted for an electronic device with a touch screen is provided. The method includes the step of displaying a touch cursor on the touch screen, wherein the touch cursor includes a positioning point; detecting whether a dragging object exists around the positioning point; and moving the dragging object to be associated with the positioning point of the touch cursor and moving the dragging object according to a movement of the positioning point when determined that the dragging object exists around the positioning point and an operating signal corresponding to a dragging action of the touch cursor is received from the touch screen.

Abstract: A touch device is configured to display a touch activated cursor on a touch screen. The touch device is also configured to detect an assistant window triggering movement of the touch activated cursor on the touch screen. In response to detection of the assistant window triggering movement, the touch device is configured to display an assistant window on the touch screen. The assistant window magnifies a portion of the touch activated cursor as well as magnifies a display area of the touch screen adjacent to an end of the touch activated cursor.

Abstract: The invention provides an electronic device including a display unit, a touch sensing module and a processing unit. The display unit displays a user interface. The user interface includes a function-enabled area and a cursor. The touch sensing module is arranged to sense a touching object corresponding to the touch event of the cursor.

Abstract: A method for operating gestures and a method for calling a cursor adapted to an electronic device having a touch area are provided. The method for calling the cursor is as follows. A first gesture input to the touch area by an operating object is received. It is detected whether a second gesture is continuously input by the operating object from an end point of the first gesture after the first gesture is input. When the second gesture is not continuously input by the operating object from the end point and the operating object leaves the touch area, a first operation is executed. When the second gesture is continuously input by the operating object and the operating object does not leave the touch area, a cursor is called and the cursor is moved to a location where the operating object contacts the touch area.

Abstract: A touch control method, adapted for an electronic device with a touch screen is provided. The method includes the step of displaying a touch cursor on the touch screen, wherein the touch cursor includes a positioning point; detecting whether a dragging object exists around the positioning point; and moving the dragging object to be associated with the positioning point of the touch cursor and moving the dragging object according to a movement of the positioning point when determined that the dragging object exists around the positioning point and an operating signal corresponding to a dragging action of the touch cursor is received from the touch screen.

Abstract: A prompting method of an adjustable direction of a cursor for a portable electronic apparatus is disclosed. The method comprises the follow steps: detecting a location of a cursor in a display, wherein the cursor indicates an indicated direction; determining whether any set direction corresponding to the location of the cursor is different from the indicated direction; if any set direction corresponding to the location of the cursor is different from the indicated direction, displaying a directional adjustment prompting information for prompting at least one adjustable direction of the cursor corresponding to the location of the cursor.

Abstract: A covered image projecting method for a portable electronic apparatus is disclosed. The method comprises the follow steps: displaying an input area in a display field; determining whether a position of an input cursor in the display field is covered by the input area; if the position of the input cursor in the display field is covered by the input area, capturing a local area image around the position of the input cursor; and projecting the local area image in the display field.

Abstract: A method for selecting multiple objects and an electronic device are provided, and the method for selecting multiple objects is applicable to the electronic device. The electronic device includes a touch screen and a processor, and the processor executes an operating system (OS). The method includes: identifying whether an application currently executed by the OS belongs to a first type application or a second type application; when the application currently executed by the OS is identified to belong to the first type application, displaying a first multi-selection button by the touch screen, where the first multi-selection button is configured to generate a first button event when the first multi-selection button is triggered ; and when the first button event is detected by the touch screen, activating or deactivating a first multiple objects selection function of the application which is currently executed by the OS.

Abstract: A touch device is configured to display a touch activated cursor on a touch screen. The touch device is configured to automatically rotate the cursor depending on movement of the cursor on the touch screen.
