Haptic glove to touch on virtual fabrics

“Virtual fabric” that feels just like the real thing is being developed by European researchers in their HAPTEX project.

Detailed models of the way fabrics behave are combined with new touch-stimulating hardware to realistically simulate a texture’s physical properties.

Detailed measurements of a fabric’s stress, strain and deformation properties are fed into a computer, recreating it virtually. Two new physical interfaces then allow users to interact with these virtual fabrics — an exoskeleton glove with a powered mechanical control system attached to the back and an array of moving pins under each finger. The “haptic” glove exerts a force on the wearer’s fingers to provide the sensation of manipulating the fabric, while the “touching” pins convey a tactile sense of the material’s texture.
