Cognitive science now provides rich insights, and the need to move to other interfaces, such as digital pens (not the stubby, rubber ended things that work with some tablets) and digital ink is now more obvious than ever. The technology to take advantage of these interfaces in powerful computers that have the light weight form factor of a tablet is now readily available.
The title of Chapter 2 sums up things up very well - "Keyboard Interfaces: The Bottleneck Constricting Communication and Performance". It is now almost as if a laptop computer with only a keyboard and no digital pen interface is a virtual 'antique'.
I believe it is time that educators started taking the lead with these enhanced interfaces that improve creativity and allow students to work more effectively in areas such as the sciences, mathematics, languages and the arts.
