In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
But in the past couple of years, Brennan believes that tablets have caught up, with apps such as Apple’s ProCreate and Morpholio’s Trace becoming far more responsive to the user’s marks. “Tablets didn’t used to have that immediate response, from brain to eye to hand to pen to paper. A half-second delay has a huge impact on how you think — it causes you to stumble. But now that lag’s gone, it’s almost the same as drawing with pen on paper. You don’t need to engage with the airbrushes or other features — just use it in its purest form.” The stylus, too, far more convincingly apes a manual pen: “You’re able to tune it to almost replicate your favourite pen — and it doesn’t run out of ink.
Chetwood is an iPad devotee, using it to produce fantastical urban artworks as well as architecture. Far from hindering the drawing process, he believes tablets will give rise to a new era of creative drawing. “A lot of people say technology and computers are taking away the true art of drawing. That’s rubbish, it releases sketching. You can move so much quicker and change things much more quickly, and it keeps a record of what you’re doing. The control is just brilliant.” The polished glass surface is the only flaw, but textured acetates applied to the screen can make it feel more like paper.
