Placebase allows users to record their story using audio, video, or a photo and text. After recording, authors tag their story with certain sensual qualities and record a photo of their visual perspective. The device records their orientation when they save the message.
Users can get an overview of all the stories dropped in any location by tapping map markers. However, the actual message is withheld until users are near the spot and their device is aligned with the author's direction, which the app logged when the message was saved.
Once users retrieve the media, they can use the five buttons corresponding to the five senses to indicate how the experience in place affected their perception. They can also leave written comments on the story. These comments show up in the author's personal collection of stories, but the author must return to the location in order to see what was said.
