Method and system for initiating data items and their computer programs Product

The present invention relates to a method and system for instructing an activation data item, and more particularly to a method and system for displaying an indication in the event that an activated data item cannot be viewed.

In recent years, portable devices, such as smart phones or notebook computers, have become more sophisticated and powerful. For example, a portable device can have network connectivity. Users can use the portable device to connect to the Internet anytime and anywhere to browse the Internet and conduct related applications and services through the network. Thanks to the convenience of these devices and their functions, these devices have become one of the must-have items for modern people, and they are frequently used in life anytime and anywhere.

With the popularity of smart phone network communication applications, users can perform network communication applications on smart phones to communicate with friends online. In general, users can enter text messages or record a voice message to a specific friend, or a group of members. A specific friend or group member can read this text message or voice message immediately or when they are available.

In general, a representative icon of a text message and a corresponding voice message can be displayed in a user interface. Due to the characteristics of voice playback, when the voice message is played, the user can simultaneously perform other things while listening to the voice, such as scrolling the user interface to view other messages in the user interface. When there is a large amount of information in the user interface, the scrolling of the user interface often causes the representative icon of the currently played voice message to disappear into the display unit. Since the representative icon cannot be viewed, the user cannot know the related information of the voice playing operation, such as the person who sent the voice message, and the progress of the playing. When the user wants to perform related play management operations on the currently played voice message, such as pause or stop, the user must scroll again. The user interface is redisplayed in the display unit until the representative icon of the currently played voice message is displayed, and the user can perform related control through the representative icon.

In addition, in some cases, the user may need to switch between different applications. For example, when a user's itinerary is mentioned in a voice message, the user may want to open the calendar application to view the itinerary that he or she has scheduled. However, conventionally, when leaving the network communication application, the playback of the corresponding voice message will be stopped. When the user wants to continue listening to the voice message, the user must re-open the network communication application and re-select the voice message. When the user receives another message in the above process, the user may need to scroll the user interface to find the voice message. The aforementioned operations are very inconvenient and inefficient for the user.

On the other hand, in an email application, users can view specific emails. In some cases, the user can look up other emails related to the currently viewed email. Similarly, when there are a large number of emails in the user interface, the scrolling of the user interface often causes the currently viewed email to disappear into the display unit. It is often difficult for users to revert to the previously viewed email.

In view of this, the present invention provides an indication method and system for initiating a data item, wherein when the activated data item cannot be viewed, an indication can be displayed to prompt the data item.
