Intelligent virtual keyboard system for networked toll collection of expressway

The invention provides an intelligent virtual keyboard system for networked toll collection of an expressway. A biological feature identification unit is used for collecting the biological feature ofa user and matching the biological feature of the user with the pre-stored standard biological feature of the user; a human-computer interaction interface unit presents a user operation unit interfaceand a virtual keyboard unit interface; a virtual keyboard unit receives the instruction information and/or text information input by the user through a virtual keyboard, sending the instruction information and/or text information to an application-layer transmission unit and making the text information automatically input into a corresponding option or table on a manual interactive interface; a voice recognition unit is used for recognizing voice information recorded by operating personnel; the application-layer transmission unit is used for transmitting a instruction to a protocol conversionunit; the protocol conversion unit is used for protocol conversion of the instruction; an interface unit is used for sending the instruction subjected to protocol conversion to a toll-collection-system control host computer. The system has the advantages of being low in cost and high in hardware portability, achieving cross-platform implementation, being easy and simple to operate, durable and the like.

Method and device for setting shortcut key in status bar pull-down menu of user interface

The invention discloses a method and device for setting a shortcut key in a status bar pull-down menu of a user interface. According to the embodiment of the invention, an XML file is set, the XML file records the shortcut key needing to be set in the status bar pull-down menu and control information of the corresponding shortcut key function, and when a mobile device runs a System UI application program, and the step of setting the pull-down menu of the status bar is executed, the control information in the called XML file is analyzed and executed, and the shortcut key needing to be set and the corresponding shortcut key function are set instead of directly executing the codes for setting the shortcut key and the corresponding shortcut key function in the SystemUI application program installation package; therefore, the shortcut key in the status bar pull-down menu of the UI can be set as required. When the shortcut keys are increased or decreased or the setting of the shortcut keys is controlled, the shortcut keys and the corresponding functions of the status bar pull-down menu of the UI can be increased or decreased only by modifying the control information in the XML file, so that the method is simple and easy to implement, and time is saved.
