Project description
The sense of touch is often overlooked in terms of how it can impact major decisions, like whether or not to buy that new gadget. Research has shown that as surface roughness increases, people tend to react more negatively, and that as people feel more negative, they tend to be more close-minded and less accepting of novel products.
But exactly how much 'roughness' is too rough? How do roughness and, say, hardness interact? And how much does product type impact that judgement?
