PowerPoint vs. Prezi and alternatives

In today's market, there are several platforms for creating visual aids, with PowerPoint and Prezi being the most prominent, each with distinct philosophies.

PowerPoint is the industry standard; its linear sequential slide structure is secure, robust and universally compatible.

It allows full control over the design if used in "blank canvas" mode rather than predefined templates. On the other hand, Prezi offers a more dynamic and non-linear visual narrative.

Its zoom and spatial movement system allows connecting ideas within an overall map, which is very attractive for explaining complex processes or relationships.

However, its excessive use of transition animations can cause dizziness or distraction if not managed with restraint.

For small groups (less than 30 people) or interactive workshops, analog tools such as a flipchart or whiteboard are extremely effective.

Writing or drawing in real time generates a sense of immediacy and closeness that no digital slide can replicate, allowing you to adapt the explanation on the fly.

Using the black screen to regain attention

One of the most useful and least known technical functionalities of presentation software is the ability to darken the screen at will.

During the presentation, there may be times when the speaker needs the audience's attention to be focused exclusively on him/her and not on the projected image, for example, when narrating a personal story or answering a difficult question.

In PowerPoint, pressing the period key (".") or the "B" key (depending on settings and language) instantly turns the screen black.

This eliminates the light source competing for visual attention, returning the spotlight back to the communicator.

This technique is also useful if the projector emits a light that hits the speaker's face as he/she moves around the stage; turning off the projection moment
