This presentation is about my master degree thesis that is focused on the realization of a new release of an existing tool for the generation of multichannel multimedia interactive storytelling artifacts. the main goal of this new release is to build automatically different versions of the same artfact upon several delivery channels, adapting it considering delivery format costraints and usage context characteristics.

1. Politecnico di Milano – Polo regionale di Como December 22nd, 2009 InteractiveStorytelling Generation The adaptiveversionof 1001Stories Gabriele Calemme Student ID : 712240 Supervisor: Prof. Nicoletta Di Blas AssistantSupervisor: Prof. Paolo Paolini

2. Tableofcontents The adaptivity concept What is 1001stories 1001Stories & adaptivity The 1001stories new release A new delivery channel: the leisure browsing

3. Whatdoesadaptivitymean?

4. 1001Stories Web basedtoolaimed at authoring multimedia narratives on differentchannels Design format Workflow Engine Cost effectiveness Goodquality multimedia applications Short span of time and scarce financial resources Museo Archelogico – sezione romana

5. The 1001stories engine The 1001Stories engineis a web service whichallows the creation and generation of multimedia and multichannelstories Authoring Preview Generator Web CDROM Podcast RSS feeds LeisureBrowsing Authoring Preview Generator

6. 1001Stories & Adaptivity Technological issues Screen size Less visual elements Podcast item’s URL needed Channel-dependent design issues 1001Stories format VS linear playlists Textual information scarcely used Contextual issues No strict visual contact Noise More tasks at the same time Concrete referencies I’M IN THE MUSEUM, WHERE IS THE ZEUS’S SCULPTURE?

7. The 1001Stories new release The idea: integrate core multimedia contents with additional multimedia fragments in order to support a specific delivery channel, following a particular design pattern Adaptive generation workflow Authoring of core multimedia contents Authoring of supporting multimedia contents Design choices specification Generation Supporting contents Delivery format adapted version Traditional 1001Stories contents Design choices

8. Authoring of supporting contents Fragments which adapt main contents w.r.t. technological, channel and contextual issues Main contents used across delivery formats, supporting contents are targeted to specific delivery formats Integration made by means of a tagging approach Tag definition Tag specification

9. Tag definition

10. Tag specification

11. Design choices specification Many versions for each delivery channel Flexibility Performed by means of tag ordering Automatic content placement Tag dependent – mediatype independent Contents reuse main pre_ipod post_ipod

12. Generation Limitations of the existing tool (1001stories) Single audio assumption Architectural dependence of the authoring tool and the generator Portability of the generated multimedia objects Single delivery channel version Proposed solution XML based generation mechanism

13. An XML based generator (1/2) Decoupling authoring / generation A set of XML decriptors allow the generator to build the version for a specific delivery channel Authoring step Contents upload (input) Version definition (input) XML descriptors and the set of multimedia contents (output) Generation step XML descriptors and the set of multimedia contents (input) The generated version (output)

14. An XML based generator (2/2) Authoring Generator XML descriptors + resources Contents Upload Version – Tag ordering ?

15. Results Communicative effective multimedia narratives Little time effort Cost effective For each delivery channel different design choices can be specified Complete VS simpler versions General purpose VS dedicated versions Podcast example iPod based storytelling Museum audio guides ...

16. A new format: the leisure browsing (1/2) Different browsing approach Emotional Without a priori goals Unstructured Suitable for a set of contents sharing the same characteristics Visual communication One picture for each topic /subtopic is presented Suitable as appetizer or for reviews The typical 1001Stories predefined pattern is broken

17. A new format: the leisure browsing (2/2)

18. Conclusions and future work Adaptivity & Communicative effectiveness Good quality multimedia objects delivered on MULTIPLE CHANNELS Short time span Little financial effort Low technological background needed Future work Authoring guide lines for each delivery channel Alternative media types integration (video, animations) New delivery channels (printing)
