Is This the Future of Enhanced Books? no comments
Researchers at Keio University are working on an ink-jet printer that can print aromas. The system uses the same technology as a standard inkjet printer, though to synthesize a wide variety of scents you would 
need thousands of scent components — unlike printing color pictures where you just need inks in the primary colors that can be mixed as needed.
Could we someday see pbooks enhanced with smell? And if that works will the technology migrate to ebooks? That is a scary thought — could Kindle 14 come with a scent emitter that would release smells associated with whatever you are reading? Perhaps the smell of decaying paper for those who miss paper books?
Trying to recreate the olfactory aspects of a recreated scene is nothing new. AromaRama and Smell-O-Vision both famously tried and failed to make movies into smellies. Even the idea of printing out scents using an inkjet is not new. A few years ago HP apparently filed for a patent on a camera that had a miniature gas chromatography probe to capture scents that could then be printed out using a special inkjet printer.
