As conference season gets into full swing more and more presenters are showing audiences that their thoughts are built upon previous work. That is often very important. What is not necessary is to show a screenshot of that journal article. It’s a presentation, not a journal club.
The evidence is clear that written material will be read and often in preference to listening to the spoken material. Adding a screenshot of a journal article is seldom of value; the quality is poor, forcing the audience to struggle to read; the image is visually redundant and the evidence that a paper has been read needs no illustration, merely comment. It is not necessary to have a visual representation of every fact or statement in your presentation, particularly articles.
