Scenarios

This section briefly describes some applications of DyPERS using the record-and-associate paradigm:

• Daily scheduling and to-do list can be stored and associated with the user's watch or other personal trigger object.
  
• An important conversation can be recorded and associated with the individual's business card.
  
• A teacher records names of objects in a foreign language and associates them with the visual appearance of the object. A student could then use the system to learn the foreign language.
  
• A story teller could read a picture book and associate each picture with its text passage. A child could then enjoy hearing the story by triggering the audio clips with different pages in the picture book.
  
• The system could be used for online instructions for an assembly task. An expert associates the image of the fully packaged item with animated instructions on how to open the box and lay out the components. Subsequently, when the vision system detects the components placed out as instructed, it triggers the subsequent assembly step.
  
• A person with poor vision could benefit by listening to audio descriptions of objects in his field of view.
  
• The visual appearance of an object can be augmented with relevant audio and video or messages. For instance, the contents of a container could be virtually exposed after it is sealed.

Many of the listed scenarios are beyond the scope of this paper. However, the list should convey to the reader the practical usefulness of a system such as DyPERS. In the following we describe one application in further depth and show test results.
