Haciendo una búsqueda en la red para una clase sobre PowerPoint que tengo que dar en un Posgrado en diseño de la identidad corporativa, me encontré con un post mío del 2001 a la lista SIGIA, donde recomendaba no usar software sino un retroproyector. Es un poco raro citarme a mi mismo, pero la nostalgia que puede provocar mi post no tiene desperdicio:

La pregunta era:
>> I’m giving a presentation on IA and am searching for a
>> presentation vehicle. I hesitate to buy PowerPoint for
>> just this one use. Any ideas?

Y yo respondía:
Do you think this is too low-tech? You can use the digital camera technique then. You need:
– to know how to visualize ideas
– computer + beamer
– video camera (even a cheap one is OK)
– whiteboard
– some whiteboard markers
all you have to do is write or draw on the whiteboard as you speak and use the camera to enlarge what you are writing down or drawing on the whiteboard.
I learnt this technique from 3 students of mine at the Amsterdam Polytechnic. Their powerpoint-less presentation was fantastic!

Y luego:
[…] if you are a good speaker you don’t really need presentation software. You don’t actually need anything at all except your voice and the audience.
If you still want to show something to your audience you can use good old overhead projectors and acetate transparencies (transparent sheets) to write or draw stuff on. These sheets are placed on the overhead projector which then displays them onto a projection screen.

For me, overhead projectors are simple to use and cost effective. And if I need to illustrate a point they allow me to create slides on the fly.

Dios mío… vaya recomendación! Parece hace un siglo que usé un retroproyector por última vez. Esa técnica de mis estudiantes debería volver a usarla pronto.
