We currently run a survey on “Implicit Personalization of Public Environments” as part of a master thesis. The thesis looks at the technical realization of this approach based on Bluetooth and mobile devices with a focus on creating an acceptable solution with regard to users’ privacy. If you are interested in the topic and can spare 5 minutes have a look at our questionnaire on implicit personalization, there is a German version of the survey, too.
The questionnaire is set up on a server (http://onlineforschung.org) that offers free hosting for scientific/non-profit surveys.
