Assistive handlebar based on tactile sensors: control inputs and human factors
Trujillo-León, Andrés; Bachta, Wael; Castellanos-Ramos, Julián; Vidal-Verdú, Fernando (Sensors, MDPI, 2018)
Tactile sensors can be used to build human-machine interfaces, for instance in isometric joysticks or handlebars. When used as input sensor device for control, questions arise related to the contact with the human, which ... -
Audio-Tactile Rendering: A Review on Technology and Methods to Convey Musical Information through the Sense of Touch.
Remache-Vinueza, Byron; Trujillo-León, Andrés; Zapata, Mireya; Sarmiento-Ortiz, Fabián; Vidal-Verdú, Fernando (MDPI, 2021-09-30)
Tactile rendering has been implemented in digital musical instruments (DMIs) to offer the musician haptic feedback that enhances his/her music playing experience. Recently, this implementation has expanded to the development ... -
