The real McCoy

At the Royal Society's Summer Science Exhibition the public were invited to touch and feel 20 wood and wood effect samples and vote on whether they are real or not. The exhibition will now be toured around the UK during the next year to collect a census of data from across the country. This will then be used to help build the first predictive model of how we judge naturalness
The physical characteristics of a surface, such as its colour, texture and surface roughness, are being linked to what is happening in a person's brain when they see or touch the surface. Once this is understood it should be possible to accurately predict what we will perceive as natural, and manufacturers will be able to design synthetic products to meet this expectation. The results could have a great impact on materials such as wood, animal skin and furs, marble and stone, plants and even prosthetics.
Ruth Montgomery of the National Physical Laboratory, said: "Our senses combine to identify natural materials. But what are the key factors, is it colour, gloss, smoothness, temperature? This is what our research is trying to establish. The focus of the research is wood, fabric and stone, but once the data is combined the aim is to produce a predictive computer model that will work for other materials. If successful the range of applications would be huge. For instance, synthetic mahogany furniture that is indistinguishable from the natural material, but won't rot or be attacked by woodworm or artificial grass so good that they use it on Wimbledon's Centre Court."
