Danmu is an interesting interaction form for people who are watching videos. Unlike the comment area beneath the video playback window, Danmu shoots the comment directly on the video overlay.
For some informal presentation, Danmu can be also used to stir up the interest of audiences. I decided to superimpose Danmu on the presentation in the recruitment speech of ‘Students Association of Science and Technology, Dept. Phys., Tsinghua Univ. (SAST-Phys-THU)’.
Thanks to the development work from Bigeagle (https://github.com/bigeagle/danmaQ) and TUNA (https://github.com/bigeagle/danmaQ), we can easily deploy a such system on our server and provide live Danmu service through web as well as WeChat.
