‘Multi-touch’ touchscreen

These state-of-the-art touchscreen surfaces are capable of discriminating between (and tracking) multiple objects, human touches, and/or elements of user-reconfigurable mechanical and/or graphical overlays.

Since Apple and Microsoft announced their own multi-touch touchscreen interfaces in 2007, for their iPhone and ‘Surface’ products, there has been significant international interest in this field of research.

As one of the pioneers of these kinds of interfaces, I was asked in June 2007 to write for The Register about what I thought about these recent commercial developments.
