CREST Survey

The CREST Survey is a questionnaire developed to know how the communication devices are used.
We are looking for your collaboration to draw a pattern about the typical use (surfing, voice calls, data download, text messages, etc.) in different context (home, work, school, transport, etc.) and positions (device close to the head, on the lap, etc.).
