A tactile handle for cane use monitoring
Trujillo-León, Andrés; Ady, Ragou; Vidal-Verdú, Fernando; Bachta, Wael (IEEE, 2015)Assistive ambulatory devices are used for gait rehabilitation and assistance. In both cases, their benefit is greater when they are used properly. As for canes, embedded sensors can be used for monitoring purposes. In this ... -
Adding Proximity Sensing Capability to Tactile Array Based on Off-the-Shelf FSR and PSoC
Castellanos-Ramos, Julián; Trujillo-León, Andrés; Navas-González, Rafael Jesús; Barbero-Recio, Francisco; Sánchez-Durán, José Antonio; Oballe-Peinado, Óscar; Vidal-Verdú, Fernando[et al.] (IEEE, 2020)Tactile sensors have been incorporated into robots to help in many tasks, such as preventing damage to humans in collaborative works or assistance or in dexterous manipulation. Proximity sensors are also common in robotics ... -
Aplicación de un guante instrumentado para evaluación de la movilidad de la mano
Verea Reina, Raúl (2021-09)En el presente trabajo se realiza la revisión, estudio y mejora de una aplicación previamente desarrollada de un guante instrumentado, para la evaluación de la función motora del miembro superior en rehabilitación.El guante ... -
Assistive Handlebar Based on Load Cells as Attendant Steering Device
Trujillo-León, Andrés; Sánchez-Sánchez, Cristina; Castellanos-Ramos, Julián; Vidal-Verdú, Fernando (IEEE, 2018)The increase in the life expectancy has pushed the interest in developing assistive technologies to extend the autonomy of the elderly. Mobility is a major concern for this population, and aids should be designed to be ... -
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 ... -
Driving Interface Based on Tactile Sensors for Electric Wheelchairs or Trolleys
Trujillo-León, Andrés; Vidal-Verdú, Fernando (MDPI, 2014)This paper introduces a novel device based on a tactile interface to replace the attendant joystick in electric wheelchairs. It can also be used in other vehicles such as shopping trolleys. Its use allows intuitive driving ... -
Equilibration device for tactile sensors on curved surfaces
Castellanos-Ramos, Julián; Carrasco-García, Álvaro; Navas-González, Rafael Jesús; Trujillo-León, Andrés; Vidal-Verdú, Fernando (IEEE, 2017)Tactile sensors are arrays of force sensing units called taxels and equilibration is necessary to normalize their response. This is commonly done by applying uniform pressure while the sensor lies on a flat surface. However, ... -
Evaluation of tactile sensors as an alternative to force sensors in an assistive haptic handlebar
Trujillo-León, Andrés; Bachta, Wael; Vidal-Verdú, Fernando (IEEE, 2017)This paper shows experimental results that confirm that tactile sensors are appropriate to provide information about the caregiver intention in an assistive haptic handlebar. Preliminary tests have been performed to identify ... -
Haptic interface based on tactile sensors for assistive devices
Trujillo-León, Andrés (UMA Editorial, 2018-02)Los países desarrollados deben hacer frente al creciente envejecimiento de su población. Un proceso de envejecimiento adecuado requiere capacidad funcional en las actividades del día a día. Así, las tecnologías de asistencia ... -
Phantom sensation: threshold and quality indicators of a tactile illusion of motion
Remache-Vinueza, Byron; Trujillo-León, Andrés; Vidal-Verdú, Fernando (Elsevier, 2024-03-13)Utilizing a randomized, blind, controlled experiment, and the ascending method of limits, we determined the minimum amplitude of motion at which individuals perceive a tactile illusion called moving phantom sensation, the ... -
Tactile Sensor-Based Steering as a Substitute of the Attendant Joystick in Powered Wheelchairs
Trujillo-León, Andrés; Bachta, Wael; Vidal-Verdú, Fernando (IEEE Transactions on Neural Systems and Rehabilitation Engineering, IEEE, 2018)Attendant joysticks of powered wheelchairs are devices oriented to help caregivers. Diseases and disabilities such as dementia, spinal cord injuries or blindness make the user unable to drive the chair by his or her own. ... -
The Goertzel algorithm for the extraction of texture features
The detection of the properties of objects is essential to deal with the manipulation of objects with artificial hands and grippers. In particular, texture detection is a common challenge in robotics. In the quest for ...
