For newer readers, multi-sensory interplay is the term for the discovery that each of our senses affects all the others, altering our overall experience for better or worse. We know, for example, that the colour, shape, texture and feel of objects in the surrounding environment can not only enhance or detract from the experience of eating but, by altering our physical chemistry, can actually alter the flavour of food and drink.
The same holds true for mood. A sense of wellbeing or a sense of agitation changes our entire experience. Aesthetics, comfort, ease of use, convenience – all these things subtly but profoundly affect our mood and alter an experience for the better. Conversely what is ugly, uncomfortable, difficult to use or inconvenient will alter our physical, sensory experience for the worse. And it is surprising how powerful an effect the smallest thing can have!
