The Latero Tactile Display is a state-of-the-art tactile display that operates by deforming the fingerpad skin with an array of laterally moving pins actuated by miniature piezoelectric bending motors.

Previously known as the STReSS2, the Latero Tactile Display is the result of sustained efforts over more than a decade by Prof. Vincent Hayward's team in the Haptics Laboratory at McGill University. More information about laterotactile stimulation, the novel approach used in this tactile display is listed in following.

The device was re-engineered by Tactile Labs and is now available in low volume for research laboratories. Please contact us for more information.
