CeBIT 2007
like every year I checked the term "Wearable" at the exhibitor list at CeBIT 2007. Conclusio: it has not really grown. I found only two companies (beside the fact that I know there are more in the future parc).
1) The Mobile Research Center
"The DemoCenter is a central component of MRC, where information and communication technologies from the field of Mobile and Wearable Computing are presented."
more here: mrc – Mobile Research Center: DemoCenter
2) FIS Fashion Innovation Service GmbH
Product spectrum is "Emerging Technologies – Smart Textiles, Smart Fabrics, Wearable Computing, Wearable Technology"
I will be there on monday whole day and visit for example Urban Tools and hope to find a nice sofa

Sometimes these things happen, you find yourself working hard in a project and waiting for results can take longer than expected. I am in the same situation and the only thing that concerns me is that there is a small possibility to have worked for nothing. I go on yet.
