The Autocue/QTV Wired Hand Controller for i-Prompt Pro iPad App. scrolls through the script in Autocue's i-Prompt Pro iPad app. at adjustable speeds. It controls the i-Prompt Pro specifically, as opposed to also the regular i-Prompt.
The Controller features a 6.5 ft cable extending from it and connects into the audio jack of an iPad. Because it plugs into the iPad, it gets its power from the iPad and thus doesn't use a battery. And because it's wired, it is completely reliable in crowded spaces with a lot of wireless activity, like at trade shows, avoiding at such places all possible interferences.
