1 Exhibition Short Description-Inertial Tracking

Exhibition Short Description-Inertial 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.

The component storyboard is very similar to the previous Exhibition Short Description-Marker-based Tracking. In this case the marker-based tracking has been substituted by an inertial tracking component.

When the user selects the audio information, a short audio description about the exhibition is reproduced, when finished, 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 ¡Error!No se encuentra el origen de la referencia.).

In-slots

Name	Type	Description
logicalAndAudESD.inSlot2	boolean	This slot must be connected to the Audio button of the user interface. This slot allows the user to ask for oral information.
hubImgESD.in	boolean	This slot must be connected to the Image button of the user interface. This slot allows the user to ask for showing an image with the label of the work of art.
andExhibit_NotDetectedESD.in2	boolean	This slot must be connected to corresponding exhibit number of the user interface component. If this slot is active, the screensaver of the exhibit will be shown when the marker is not detected.

Out-slots

Name	Type	Description
inertialTrackingESD.detected	boolean	True when the inertial tracking is on, false otherwise.

Main Properties

Each of the composed components defined for the Museum specific domain has lots of properties, which can be configured with the AMIRE Authoring environment. Each composed component has as many properties as the sum of the properties of each component it is composed of. Here are described the main properties:

dimension	doubleVector	Values (width and height) that fix the dimension of the image

inertialTrackingESD

Name	Type	Description
compass	integer	Controls the state of the compass component of the InertialCube. The tree possible modes are GEOS, Dual and Fusion modes.
enhancement	integer	In order to provide the best performance for a large range of various applications, three levels of perceptual enhancement are available. Mode 0 for best accuracy, Mode 1 adds a jitter reduction and Mode 2 for immersive applications.
sensitivity	integer	Only used for perceptual enhancement set to mode 1 or 2. It controls the minimum angular rotation rate picked up by the Inertial Cube.
prediction	integer	Inertial sensors can predict motion up to 50ms into the future, which compensate for graphics rendering delays and further contributes to eliminating simulator lag.
