industrial design engineering, royal college of art david sweeney 2007 Exploratory Concepts a selection of the many smell diffusers on the market At the early stages of the project, there were many different directions that this Odour Associative Learning Tool could of taken, from the simple scratch and sniff card that helps students focus on various topics during exams to the more complex solution that I have ultimately taken. These are presented in chronological order of exploration. The Odour Tagging Camera. 10
industrial design engineering, royal college of art david sweeney 2007 Initially I developed a proposal for a Smell-Induced Memory Device. The mechanism for this can be simply put: an odour is associated with the emotion that is present during the first exposure to the scent. When that smell is subsequently experienced, the emotion, and hence the connected memories, are involuntarily evoked. What if we could create a device that could capture the ambient odour, analyse it, store its character digitally, and generate the scent on demand by mixing together the necessary primary odours. In essence, we would have a memory recorder. There has been some attempt by others to achieve this but most involve the inherent inaccuracies mentioned above (theory summery). Their devices are usually very large too. My following solution requires a small device (with no limit to the miniaturisation of the device, see later) and no inaccuracy in the recreation of the odour. - This is a device that provides a novel smell ambiently or on demand, mixed from a selection of novel smells. - The exact formula is random but unique to a single event and is stored for future reference. -The device can be called upon to reproduce the same smell. Not an approximation, but the same smell. The problem has been reduced from device that requires a very accurate mass spectrometry component and at least a hundred primary odours that poorly recreate an odour, to a device where there is no need for odour analysis and only a handful of primary odours required to EXACTLY recreate an odour. Where do you start looking for novel smells? I have been in contact with Dr Rachel Herz a professor at Brown University as she has experience sourcing and creating novel odours for use in her Odour Associative Learning experiments. It’s a trial and error process but there are techniques for finding the most suitable smells. The following set of images is a selection of possible physical manifestations of the memory device. 11
