Just seen a cool presentation of projected makeup, done by Nobumichi Asai:
Indeed nice concept and I thought it might be consumerized by adding mobility. In the word where people are going with Google Glass on the streets, there is a place for a mobile makeup projectors as well…
So it can be with or without reflector, but the idea should be clear:
The video transceiver is projecting a picture and capturing as a feedback for face movement recognition, adaptation to facial expression and open eyes/mouth.
All logic and control is done remotely from the smartphone.
Big variety of additional applications – for example market of projected makeup templates (including interactive), another example makeup location based alignment (while it is controlled externally for all party participants to create large scale performance), interactive adaptation to mood expression (so it might be flowers when happy and fire when angry).
