Various forms of display devices can be embedded in the electronic device. Examples of various forms of main display devices include, but are not limited to, electronic visual display, electronic ink display, Liquid crystal display (LCD), cathode ray tube (CRT), light emitting diode (LED) display, plasma display and electroluminescent display.

[0024] The electronic device producing the main display video enables a user to view the applications. The electronic device producing the main display video can be a standalone display device. Further a plurality of electronic devices can be interconnected to one another. Furthermore, the electronic device producing the main display video can include a server associated within. One or more personal display devices can be connected to one or more or more servers that are associated with multiple electronic devices. The connection of one or more personal display devices to one or more or more servers enables the personal display devices to display a variety of display contents associated with multiple electronic devices producing the corresponding main display videos simultaneously.

[0025] The electronic device producing the main display video 305 can be connected to the server 315. The electronic device producing the main display video 305 can be connected to the server 315 directly or through communication standards, for example universal serial bus (USB) and the like. The server 315 can be regarded as a software application that allows efficient exchange of data and touch inputs between the electronic device producing the main display video and the personal display device. The data can include information associated with an application, video information and the like. The server 315 is configured to communicate with a plurality of electronic devices producing the main display devices. Further, the server 315 is also configured to communicate with a plurality of personal display devices. The server transmits the touch inputs provided by the user using the personal display device to the electronic device producing the main display video. Further, touch inputs provided by the user can be transmitted from the personal display device to the server through the network. Furthermore the server transmits the touch inputs provided by the user to the electronic device producing the main display video through physical layer. The server restrains from utilizing the session layer to transmit touch inputs provided by the user to the electronic device producing the main display video thereby avoiding transmission complexities.

[0026] Performance of the server depends on various parameters. Examples of various parameters include, but are not limited to, total number of personal display devices connected to the server. The personal display devices 320A and 320B is connected to the server 315 directly or through the network 310.

[0027] The electronic device transmits data to the server 315 directly or through the network 310.

[0035] At step 435 the user provides touch inputs to the video data associated with the application using the personal display device. The user employs the selection panel and the pointing device for providing touch inputs. The video data associated with the electronic device producing the main display video is executed by imparting touch inputs to the video data. Touch inputs are provided by the personal display device to the video data through the server. The server transmits the touch inputs provided by the user using the personal display device to the electronic device producing the main display video. Further, touch inputs provided by the user can be transmitted from the personal display device to the server through the network. Furthermore the server transmits the touch inputs provided by the user to the electronic device producing the main display video through physical layer. The server restrains from utilizing the session layer to transmit touch inputs provided by the user to the electronic device producing the main display video thereby avoiding transmission complexities.

[0036] At step 440 the personal display device maps the touch inputs provided by the user with the video data. The mapping aids to provide appropriate touch inputs from the personal display device to the video data associated with the electronic device producing the main display video. The server facilitates the mapping of touch inputs with the video data associated with the electronic device producing the main display video. Mapping is performed using software installed in an operating system of the personal display device. Examples of operating systems include, but are not limited to, Mac OS, Windows, Ubuntu, Android, Nokia and N-touch platforms.

[0037] At step 445 touch inputs provided by the user using the personal display device is transmitted to the server. The server acts as a communication medium between the user and the electronic device producing the main display video. Further, the touch inputs from the personal display device are transmitted to the server through the network.

[0038] At step 450 touch inputs are transmitted by the server to the electronic device producing the main display video . The server transmits touch inputs to electronic device producing the main display video directly or by using communication standards, for example, USB and the like. The main display device displays the video data on the personal display device in response to the touch inputs provided by the user. The method ends at step 455.
