Slideshows are a technology which has really run out of steam, but which has not yet been superseded.
Today’s invention offers a small way to augment slideshows by improving their automatic timing using content sensitivity.
The basic idea is that each slide would have the number of ‘items of interest’ in it counted, by software, and then its duration on-screen would be calculated to be in proportion.
A team photo with 30 faces in it would be on-screen for longer than a single portrait.
This works particularly well for faces, now that selfie culture and its associated software are everywhere. The approach could be applied even to technical presentations, so that a lecturer could simply label slides of greatest importance with eg ****, so that these would stay on show for longer than those labelled *.
