Multi screen interaction is the future development trend of wireless projection in multi screen interactive conference room.

multi screen interaction refers to that the communication content can be seamlessly connected and transmitted between mobile phones, TVs, pads, outdoor screens, digital electric screens and other terminal devices, and can be well compatible on each terminal to realize the communication and interaction of digital multimedia content across media and wide coverage. Through the real-time control of intelligent terminal, the contents displayed on various screens can be synchronized, and the screen interaction between terminal and user, user and user, and terminal and terminal can be completed.

(I) multi screen interactive content dissemination.


multi screen interactive content communication refers to displaying different communication contents according to different terminal forms. The content dissemination based on multi screen is not the synchronous dissemination of the dissemination content on the mobile phone, pad and other terminal screens. But based on different terminals, different content display methods and communication solutions are given. In the whole communication process, the role of the audience gradually changes from one-way receiving information to two-way interactive role. One of the important research contents of multi screen interactive wireless projection communication is the content communication mechanism of multi screen interaction, that is, how to accurately customize the communication of personalized content according to the characteristics of different screen terminals.

(II) technical realization of multi screen interaction.


at present, the integration of three networks is constantly improved and developed, and the technology of multi screen interaction is changing with each passing day. Based on wireless Internet and cloud computing technology, we can unify and integrate different terminals in modern home, business, education, entertainment and other environments, form a multi screen digital device with mobile Internet media and TV media as the main operation carrier, pad, vehicle screen, building splicing screen, projector and other multi screen digital devices connected with each other, and realize interactive manipulation, content sharing and function integration.

II. The development trend of multi screen interaction

the same content, different screens and different communication and display methods are the requirements for the realization of multi screen interaction. According to the different characteristics of each terminal, the pushed content should focus on each other, learn from each other’s strengths and complement each other, so as to form complementarity, and truly realize the aggregation and communication effect of multi screen linkage. The communication content should be deeply excavated from the aspects of refinement, interactivity and uniqueness. Through big data technology, accurately classify, locate and analyze the habits of media audiences, and customize the communication content. Pay attention to audience experience and different audience needs. In the process of customizing content, different audiences adopt different forms and styles.


. For example, on the mobile Internet side, it is necessary to highlight the fragmentation and conciseness of the communication content, highlight the key points and make a single breakthrough, so as to facilitate the audience’s small screen reading and secondary communication as the main consideration; For another example, for elite groups such as white-collar workers and opinion leaders, logical and speculative high-quality communication content is the main reading demand, and the real-time, accurate and localized content should be highlighted in the communication process.

, and

will be put on the screen. Facing the new changes and new requirements brought by the multi screen era, the content communication of traditional media can no longer be limited to the production of single content. It is necessary to change the way of one-way communication, try to use new media for diversified content communication, try to widely apply multi screen interaction to content communication, and constantly adjust the communication strategy to meet the communication requirements of the mobile Internet era.
