1. Technical Field
The disclosure generally relates to data sharing technologies, and particularly relates to desktop sharing methods and systems.
2. Description of Related Art
Desktop sharing allows one user (known as the Publisher) to share the content displayed on the Publisher's monitor with one or more remote users (known as the Viewers) via a local area network (LAN) or the Internet. Either a LAN or the Internet requires at least one third-party network device such as a router or an Internet access point (AP) to establish a desktop sharing session between the devices of the Publisher and the Viewers. However, it may be inconvenient for the Publisher and the Viewers to carry the third-party network device. Under some circumstances, for example, when the Publisher meets the Viewers outdoors, their devices may not have accesses to either a LAN or the Internet, and thus the Publisher cannot share the content displayed on the Publisher's monitor with the Viewers.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings, in which like reference numerals indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”
In general, the word “module,” as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language such as Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an erasable-programmable read-only memory (EPROM). The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of non-transitory computer-readable medium or other storage device. Some non-limiting examples of non-transitory computer-readable media are compact discs (CDs), digital versatile discs (DVDs), Blu-Ray discs, Flash memory, and hard disk drives.
Although only one viewer device 104 is shown in
Each of the publisher device 102 and the viewer device 104 supports a Wi-Fi direct (WFD) functionality. A data communication connection may be established between the publisher device 102 and the viewer device 104 via a Wi-Fi direct (WFD) network. The WFD network is a network system suggested by the Wi-Fi Alliance and enables Wi-Fi devices to be connected to each other in a peer-to-peer (P2P) fashion without participating in a home network, an office network, or a hot-spot network. Therefore the publisher device 102 may send data directly to the viewer device 104 via the data communication connection without using any third-party network device.
The illustrated embodiment of the device 20 includes, without limitation: at least one processor 202, a suitable amount of memory 204, a user interface 206, a WFD module 208, a display 210, and a file system 212. Of course, the device 20 may include additional elements, components, modules, and functionality configured to support various features that are unrelated to the subject matter described here. In practice, the elements of the device 20 may be coupled together via a bus or any suitable interconnection architecture 214.
The processor 202 may be implemented or performed with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination designed to perform the functions described here.
The memory 204 may be realized as RAM memory, flash memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. The memory 204 is coupled to the processor 202 such that the processor 202 can read information from, and write information to, the memory 204. The memory 204 can be used to store computer-executable instructions. The computer-executable instructions, when read and executed by the processor 202, cause the device 20 to perform certain tasks, operations, functions, and processes described in more detail herein.
The user interface 206 may include or cooperate with various features to allow a user to interact with the device 20. Accordingly, the user interface 206 may include various human-to-machine interfaces, e.g., a keypad, keys, a keyboard, buttons, switches, knobs, a touchpad, a joystick, a pointing device, a virtual writing tablet, a touch screen, a microphone, or any device, component, or function that enables the user to select options, input information, or otherwise control the operation of the device 20. In various embodiments, the user interface 206 may include one or more graphical user interface (GUI) control elements that enable a user to manipulate or otherwise interact with an application via the display 210.
The WFD module 208 may establish a P2P data communication connection with another WFD device via a WFD network. In the context of this description, the WFD module 208 can be employed during a desktop sharing session that includes the device 20 as one of the participant devices.
The display 210 is suitably configured to enable the device 20 to render and display various screens, GUIs, GUI control elements, drop down menus, auto-fill fields, text entry fields, message fields, or the like. Of course, the display 210 may also be utilized for the display of other information during the operation of the device 20, as is well understood.
The file system 212 may be implemented using well known and conventional software, firmware, and computer programming technologies. The file system 212 may cooperate with the operating system (OS) of the device 20 to store, manage, and organize electronic data, files, folders, and other items. The file system 212 may be involved when the device 20 shares data with another device.
