Analysis of a single interaction

I revived this Analysis of a single interaction recently thanks to a PhD student who is working on user-centred design. It was first developed in 1988 based on Donald Norman’s work, applied to the kind of computer software we were designing then. The ‘concept keyboard’ mentioned was a programmable touch pad from that era which enjoyed considerable popularity as it allowed an interface based on the developer’s own visual layout, suitable for younger and special needs pupils – a precursor of the iPad!
