Using the model of the Attention Seeker a tool bar appears once swiped to inform a viewer the current point in the duration of the film.
Like the Attention Seeker we made for the experiment, it could discreatly fade in and out at the bottom of the screen, show the duration of the video and indicate through the timeline bar what stage the video is at when you swipe. Because the unique identification number on the card for this application is not required, it would be possible to use cheaper, lower frequency tags and readers, or even use this function inconjunction with others.
This idea also goes hand in hand with, Attention (Re)Starter, where the swipe actually takes you to the beginning of the film. The problem with this idea is the same as the egg timers you get in sauna's, if it has been started before you, you need to wait either until others have left or until its ready to start again anyway. But maybe if the reader could see everyone enter and exit the screening space, it would know if you were alone and know if it were able to restart the video.
