Presentation of slides normally is the key to a successful lecture. And almost every lecture, speaker would have needs to use gesture pointing out some positions of its slides to make people to pay special attention. However, in some situations, especially the situation that lecture happened in small room, the speaker may have to cut out some other part of slides to finish his gesture. And there's a big chance that part may also have some relationship with the attention point(otherwise it shouldn't appear in the same page...). In this disclousre, we provide a method to address this issue by spiliting the whole slide into two part and contain the speaker in it.
