SKYWORTH multi-screen interaction is a super practical software that liberates teachers from the platform. Through this software, teachers can directly control the all-in-one product through mobile phone and tablet, and upload files, videos and courseware without pressure. They can also take excellent notes and upload them to the large screen in real time. Teachers and students can share and interact with each other. The in-class test can be set up at any time, and students can complete the test and upload the answer results by using the tablet, so as to check and fill the gaps in time.
