ABSTRACT
In this paper we describe the technical part of the DigitalJewellery project at the Institute for GeoinformaticsMünster, Germany. This project takes place duringsummer term 2007. The two main parts are a video playercontaining a bluetooth scanner running on our iDisplaysand several digital jewellery created by Jayne Wallace andPatrick Olivier at the Culture Lab Newcastle of theUniversity of Newcastle. This text focuses on the softwarepart, not the digital jewellery part.

INTRODUCTION
During the last years, large displays have been gettingcheaper and cheaper. So more and more large displays areplaced into the environment. The Digital Jewellery projecttries to establish a more personal connection betweenpeople and these displays. Normally, only impersonalinformations are shown on displays, like news, timetablesor commercials. But these displays could also be used forshowing some more of „you“. Our idea is to create somedigitial jewellery what will be recognized by displays andshow some personal information about you. In case youthink, personal information are only your name, youraddress, your birthday, your mobile phone number, etc.,you're wrong! How about showing some holiday photos ormovie clips? Or movies from your work or hobbies? Or amovie clip you've just taken on your way to work? Maybeit would be cool to show to your friends or colleagues orjust any person walking by the displays with you. We tryto find out how you and the environment will react to this.
TEST SETUP Technical requirements
Currently six iDisplays are running 24h at the Institute forGeoinformatic. They are placed at both entrances of theinstitute and evenly spreaded at the office corridors, soevery IfGI member walks by at least one iDisplay on hisway to his office or lecture room. During a normal day,everybody will walk by more than one display. This isnecessary because our iDisplay are a major part of the testsetup. The digital jewellery is created individually forevery person based upon the video clips they recorded. Thejewellery are invented by Jayne Wallace and PatrickOlivier at the Culture Lab Newcastle.A bluetooth scanner software has been developed duringthe project “Interaction with public displays” at the IfGI insummer term 2006. The code will be re-used and adjustedto the needs of the Digital Jewellery project. Additionally avideo player software will be developed using Java andcoupled with the bluetooth scanner.The software will run on the iDisplays and scans enduringits environment for the digital jewellery. If any digitaljewellery is found, a video clip will be loaded and shownon the iDisplays.The software will run 24h a day during the evaluationperiod.
General conditions
The evaluation of the whole project will take place duringaugust and September 2007. Because of the focus of thispaper on the technical part of the project, the result of theevaluation will be available in another paper. The fourselected participants are a professor, an institute employee,a PhD student and a Graduate student, so there is noproblem because of the evaluation period isn't locateddirectly in the summer term.
TEST PROCEDURETechnical part
During the last projects using bluetooth in any way, theopen source java bluetooth implementation BlueCove hasproved its vantages. The major disadvantage of BlueCove,the missing Linux implementation and the only usage ofthe Microsoft bluetooth stack, can be left out of focusbecause all of the iDisplay systems are running WindowsXP SP2. The used video clips from the participants arelocated on (different) webservers so that the video playeris able to load them on demand and video clips can beexchanged without the need of changing anything on theiDisplays directly
