Last Saturday, the wedding of Prince Harry and actress Megan Markle took place. Part of the ceremony was held by Bishop Michael Curry, who read the text from the iPad screen.
The clergyman did not have to turn the pages during the ceremony. Probably, he was helped with this special software.
For example, PromptSmart Pro is a program that recognizes the voice and pulls the subsequent text on the device screen. Or Teleprompter – an application in which you can set the speed of appearance of text on the screen.
