Using an Ultrasonic Transducer to Produce Tactile Rendering on a Touchscreen

Archive ouverte : Communication dans un congrès

Giraud, Frédéric | Giraud-Audine, Christophe | Amberg, Michel | Lemaire-Semail, Betty

Edité par HAL CCSD

International audience. Friction reduction based tactile devices use an ultrasonic vibration to create an overpressure between a user's fingertip and the vibrating surface. This phenomenon is called "the squeeze film effect". This is an emerging technology to produce a haptic feedback on the touchscreen of handheld electronic devices. In this paper, we present the technology and the main technological issues to be improved.
