PechaKucha presentation
PechaKucha, which is Japanese for „the sound of conversation“, was first conceived by Tokyo architects Astrid Klein and Mark Dytham. PechaKucha presentations are based on a 20 x 20 principle: 20 slides are presented, each slide lasts for 20 seconds, the slides are automatically advanced.
Due to this strict timing, each PechaKucha presentation lasts exactly 6 minutes and 40 seconds. PechaKucha slides usually use images, rarely many words. Presenters must know what to say without looking at the slides. A presenter can reasonably speak 2 to 4 sentences or 33 words in 20 seconds.
