"Lucida" consists of a wristband which vibrates every hour to remind the wearer to perform a "reality check". This check typically involves touch one's hand with the other hand' finger. During the day it is obvious that the finger will not behave abnormally. During the night in the REM Phase – the phase where dreams are most likely to happen – the wristband will also vibrate because it registered the wearer's sleeping phase. The vibration could then trigger a reality check in the dream which would result in abnormal behaviour like that the finger is piercing through the hand. At that moment the wearer would realize she is in a dream.

This project was based on research in lucid dreaming which showed that there is a higher change of inducing lucid dreams by vibration during the sleep cycle. I drafted out a storyboard which was critiqued during one of the course lectures. It seemed that the explanation of the actual concept was much harder then explaining the actual interaction.

The poster that I designed focused more on the explanation of the concept of reality check and intend instead on the interaction. The frist draft seemed to be much of an advertisment therefore I tried a different approach which ended in the final version.

Explaining a concept right needs a lot of iterations and testing with user and third parties. One can get lost easily in the nitty-gritty details and forget about the overarching theme and the key features.

I was responsible for the idea, interaction and the graphic design.
