Exhibition Short Description-Marker-based Tracking

Description

The purpose of this exhibit is to give the visitor basic information about the works of art in the gallery. The information provided will correspond with the information currently included in the label of each work of art.

This component is based on the Work of Art Information Component.

When the corresponding marker is detected, the user will be presented a list of the works of art located in the gallery. When the user clicks one of the pictures the information about the work of art selected will be shown to the user. The information shown for each work of art has been described in detail in the work of art information description (See section 5.2.2.10.1).
