Potential for touch screens found at your fingertips



Our sense of touch is clearly more acute than many realize. A new study demystifies the “unknown sense” with first-ever measurements of human tactile perception.

In a ground-breaking study, Swedish scientists have shown that people can detect nano-scale wrinkles while running their fingers upon a seemingly smooth surface. The findings could lead such advances as touch screens for the visually impaired and other products, says one of the researchers from KTH Royal Institute of Technology.
