===Availability===
''Sugarcane Island with Alfred'' is an IS system which was developed as a research prototype. It is not available for download.
Nevertheless, you can get most of the technical components used for implementing the system.

===Technical Description===
Sugarcane Island with Alfred is a two player Interactive Storytelling application that adapts a part of the story of the game book "Sugarcane Island" by Edward Packard.
The users find themselves stranded on an unknown island and need to find a way to survive.
The story is narrated by an embodied virtual character named Alfred.
Decisions between the text parts are realized with a Wizard-of-Oz speech input. Alfred asks for a decision and the users have to speak out their choice.
Full Body Gestures are added in Quick Time Events, were the users have to perform a specific gesture given a limited amount of time. The recognition of these gestures using Microsoft Kinect is done with the [http://www.hcm-lab.de/FUBI.html FUBI] Full Body Interaction Framework.

The general application runs on the [http://www.hcm-lab.de/project/GamEngine Horde3D GameEngine]. In Addition, [http://www.informatik.uni-augsburg.de/lehrstuehle/hcm/projects/scenemaker/ SceneMaker] was used to model and execute the story as a hierarchical finite state
machine extended with multimodal scene scripts that consist of the text to be spoken including additional commands like animations or sounds.

===Strong Points===
The potential of this ITS application lies in the interaction interface designed for two players.
It uses the Microsoft Kinect sensor to recognize full body gestures of the users that do not have to hold or wear any interaction device.
The story itself is adapted from the game book Sugarcane Island.
The strength of this approach is, that there is no need for writing a complex story, but the given story can be directly used to investigate the interaction interface.

===Limitations===
The full body gestures are currently applied in so-called Quick Time Events, where the users have to perform a specific gesture during a limited amount of time.
A next step would be to provide real decisions by offering a choice of different gestures or even some kind of gesture syntax.

===Supporting Narrative Theories===
None.

===Computational Model===
The story is modeled with [http://www.informatik.uni-augsburg.de/lehrstuehle/hcm/projects/scenemaker/ SceneMaker] as a hierarchical finite state
machine extended with multimodal scene scripts.

===Type of interaction===
Interaction using Microsoft Kinect to recognize full body gestures.
In addition, Wizard-of-Oz speech input for decisions.
