DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
FIG. 1 is a flowchart of an information display method according to an embodiment of the present invention. FIGS. 2A ̃2C are diagrams of an information display method according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2A, in step S101, a portable device 200 presents a standby situation, wherein the portable device 200 may be a smartphone, a personal digital assistant (PDA), a PDA phone, or a touch phone, and the standby situation refers to an operation mode or a screen locked mode in which the portable device 200 remains turned on and connected.
The portable device 200 has a display unit 202 for displaying a standby layout 204, wherein the display unit 202 may be a touch screen. The standby layout 204 includes a main menu 206 when the portable device 200 is in the standby situation. Namely, the portable device 200 is in the standby situation when the main menu 206 is displayed. In FIG. 2A, the main menu 206 is presented as a quadrangular picture and disposed in a center area of a visible region 202a of the display unit 202. However, in the present invention, the shape, presentation, and disposition of the main menu are not limited to the quadrangular picture. Namely, the main menu may be in any polygonal shape, and the main menu may also be a screen background image, a text, or a color block other than a picture. Moreover, when the main menu 206 is, as shown in FIG. 2A, a picture, the main menu 206 may also be disposed at any place within the visible region 202a of the display unit 202.
Next, referring to FIG. 1 and FIG. 2B, in step S103, at least one event is generated in the portable device 200. The event may be a missed call, a short message, or an event reminder, wherein the event reminder includes a task reminder, a conference reminder, or an interview reminder issued by an operating system of the portable device 200 according to a schedule pre-established by a user.
After the event is generated (step S103), in step S105, the standby layout 204 is changed (as shown in FIG. 2B) to add a movable field 208 in the visible region 202a of the display unit 202 (as shown in FIG. 2C), wherein the main menu 206 and the movable field 208 coexist in the visible region 202a. The standby layout 204 may be changed into the standby layout 204a to add the movable field 208 by moving the main menu 206 (referring to FIG. 2B) and disposing the movable field 208 around the main menu 206. Namely, as shown in FIG. 2C, when the main menu 206 is moved toward one side of the visible region 202a of the display unit 202, the movable field 208 is added at the other side of the visible region 202a. In an embodiment of the present invention, the step of moving the main menu 206 further includes changing the content, shape, and color presentation of the picture displayed by the main menu.
In addition, the movable field 208 displays the event. The movable field 208 may only display the type of the event or display part of the content of the event. Besides, the movable field 208 further includes at least one sub field 208a for sequentially displaying a plurality of events according to a priority sequence preset by the user. The priority sequence of the events may be determined according to the occurrence time of the events or the significances thereof. The method of displaying the events according to the priority sequence includes displaying a dynamic caption in large font, bold font, high contrast color, and flashing effect or displaying the event having the highest priority at the top field of the sub field 208a. 
In an embodiment of the present invention, in the standby situation, the display position of the movable field 208 is changed in the visible region 202a of the display unit 202 every time when an event is generated. Namely, every time when a event is generated, besides displaying the event in the movable field 208, a displacement of the movable field 208 is further generated in the visible region 202a of the display unit 202 to change the display position of the movable field 208.
In another embodiment of the present invention, the relative position between the movable field 208 and the main menu 206 is changed in the visible region 202a of the display unit 202 every time when an event is generated. Namely, every time when an event is generated, a relative displacement between the movable field 208 and the main menu 206 is further generated in the visible region 202a of the display unit 202 besides displaying the event in the movable field 208.
Moreover, besides reminding the user through visual change produced by changing the standby layout every time when an event is generated, a sensory signal may be further generated to enhance the reminding effect. The sensory signal includes a change in the screen backlight, a change in the color presentation of the main menu, an audio signal, and a vibration signal.
As described above, in the present invention, when a portable device presents a standby situation while the operating system thereof works normally and still receives communication messages, missed calls, received short messages, and event reminders issued by the operating system of the portable device are all displayed as events within a visible region of a display unit. Thus, a user can get to know about the events from a movable field added for displaying the events without having to unlock the display unit or switch the portable device from the standby situation to a working situation. Moreover, when an event is generated, the main menu is changed (for example, by moving the main menu, changing the content, the shape, or the color presentation of a picture displayed by the main menu, or changing the relative displacement between the main menu and the movable field) so that the user can be visually alarmed of any change in the standby image displayed in the display unit and accordingly get to know about the occurrence of the event. Thus, the user can get convenient and explicit event reminders without having to unlock the display unit, switching the portable device from the standby situation to the working situation, or initiatively looking for the event in the display unit. Thereby, the information display method in the present invention improves the convenience and adaptability of the portable device.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
