CRAFT – EPFL
Project CityNotes

A Collaboration between EPFL, CH and Proboscis, UK

Description of Tasks of CRAFT

The following text contains the description of the phases of development connected to the project of collaboration between EPFL and Proboscis. It has to be highlited that proceeding to the phases described here is complementary to the completion of the previous phase, and given the availability of resources on both sides.

Phase 1_ Estimate completion time: 2 months_
Goal of this phase is to adapt the current Urban Tapestries interface to the needs and requirements of the project. Practically an internal module will be implemented (B), which will serve in the client side to access the Global Positioning System (GPS: B) functionality of the phone for a precise positioning. At this stage the client in use is provided by Proboscis, and is implemented in Symbian S.D.K.. In addition to this point we will start building a very specific module, called Smart Layering of Information (SLI: A), which will organise the system messages providing the necessary description for the filetering/retrieval. At this stage this module will be partially working because it will need the elaboration of the algorithm which will follow the analisys of the data provided by experiments. Proboscis will operate on the server side to adapt the log capabilities of the system to take track of all the interactions aspect needed by the SLI module.

Phase 2_ Estimate completion time: 8 months_
The aim of this phase is to port the existing Symbian interface of the client to Java 2 Micro Edition. In this way the client will be able to operate on more phones and more testers will be able to join the experiments running in London. The GPS Module B will be rewritten to fit into the new architecture of the client. New functionalities of the interface may be added to correspond to the implemented filtering capabilities of the SLI module A. This last module will be completed given the results of the pre-experiment done with the system running at phase 1.

Phase 3_ Estimate completion time: 6 months_
The target of this phase will be to complete the client interface with the implementation of a GIS module, hereafter module D, which will consent the network streaming of the maps from the server to the client. An appropriate module for the treatement of the vector data will be implemented both on the client side and on the server side, module D and E.
