Design of innovative haptic peripherals for multi-finger applications

 CTI project in collaboration with Logitech SA

Project description

With the aim of providing a new touch experience to the user, several haptic devices are developed, including a complete force feedback keyboard and vibrotactile touch sensors. A specific methodology is proposed to optimize linear short-stroke actuators, flat vibrators and other electromechanical actuators. Several position detection methods are developed to allow for an accurate impedance control of miniature force feedback buttons.
