Description

  The present invention relates to a presentation device, and more specifically, enables audiences and attendees in presentations and lectures to understand and convince the content (lecture content, etc.) more deeply, and also presenters and lectures. The present invention relates to a presentation device in which a speaker such as a speaker can improve the quality of content or easily revise the content.

  Conventionally, many proposals have been made regarding presentation devices or presentation systems. For example, Patent Document 1 (see page 1 and FIG. 1) and Patent Document 2 (see page 1 and FIG. 1). As disclosed in Patent Document 1 and Patent Document 2, etc., a presenter, a speaker, and the like make a presentation while pointing an image projected on a screen with a pointing stick or the like. Presenters (presenters, speakers, etc.) may be located in the projection path. In this case, since the presenter, the pointing stick, and the like are overlaid on the screen and become shadows, there is an adverse effect (defect) that it is difficult for the audience and attendees to see the video. In addition, speakers such as presenters and lecturers have a problem in that the projection light from the projector enters the eyes and feels very dazzling.
