#WIPTTE13 Keynote: Andy van Dam – Pen and Touch Computing: From Research to Resource #edchat

Ivan Sutherland’s Sketchpad: one of the most influential programs in the history of graphical user interfaces – http://www.youtube.com/watch?v=mOZqRJzE8xg

One generation does not make the previous generations work obsolete, it augments it.

We need to make the interaction between human’s and computers smarter
What is the ultimate user interface? It must feel good. Ask a violinist how it feels to hold a really wonderful violin?
The importance of transparency and fluidity. We need to be able to concentrate on our task uninterrupted. Ease of learning is not equivalent to ease of use.

The first thing kids do today when they walk up to a screen is touch it. And if it doesn’t do anything, they think it’s broken.

Where do pens make sense?
Ideation and sketching
We want transparency with full computational power
Syntax, semantics and structure – we know it, let’s leverage it

Where toes touch come in?
Where fine-motor control is unnecessary (touch and click, swipe/flick, pinch-zoom)
Popularized by smartphones
Multi-point vs true multi-touch (full-finger ellipse)
Point suffice for touch-and-click, swipe, and pinch/zoom
Touch can simulate pressure

Tablet PC: MathPad
Mathematical sketching and very simple animations

Touch provides an emotional experience beyond the visual experience, however wonderful that might be.
