Multi-Finger Haptic Devices Integrating Miniature Short-Stroke Actuators

The omnipresence of electronic devices in our everyday life goes together with a trend that makes us always more immersed during their utilization. By immersion, we mean that during the development of a new product, it is more and more required to stimulat ...

Force feedback keyboard: self sensing

Yves Chevallier

Within the framework of a project consisting in developing a haptic keyboard, each key is aimed to be controlled individually in position and force. Small sized actuators has already been designed and integrated in a 64 keys force feedback keyboard. The pr ...

Synaptic Mechanisms Underlying Sparse Coding of Active Touch

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, James Poulet

Sensory information is actively gathered by animals, but the synaptic mechanisms driving neuronal circuit function during active sensory processing are poorly understood. Here, we investigated the synaptically driven membrane potential dynamics during acti ...

Designable Visual Markers for Mobile Human-Computer Interaction

Enrico Costanza

Visual markers are graphic symbols designed to be easily recognised by machines. They are traditionally used to track goods, but there is increasing interest in their application to mobile human-computer interaction (HCI). By scanning a visual marker throu ...

Augmenting Face-to-Face Collaboration with Low-Resolution Semi-Ambient Feedback

Khaled Bachour

Conversations are a daily human activity, and a crucial part of face-to-face collaboration in virtually any context. It is also a highly engaging activity that requires the full attention of participants involved in it. This is why computers have generally ...

Capacitive flexible force sensor

Martinus Gijs, Jagoda Anna Dobrzynska

We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...

Two-handed haptic feedback in generic virtual environments

Renaud Ott

Since [years] we hear about Virtual Reality as a discipline that could potentially provide benefits to many applications. Basically, the principle of Virtual Reality consists in stimulating user senses in order to give the impression to be in another place ...

LTCC free-standing structures with mineral sacrificial paste

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Olivier Triverio

In this work, mineral sacrificial pastes (MSP) previously developed for standard thick-film technology (alumina substrates) are extended to LTCC in order to make a capacitive anemometer. Application of MSP materials on free-sintering (unconstrained and not ...

A Haptic Knob with a Hybrid Ultrasonic Motor and Powder Clutch Actuator

Hannes Bleuler, Dominique Chapuis, Etienne Burdet, Xavier Michel

In haptics, the forces to be displayed vary widely in terms of magnitude and bandwidth. A single actuator can hardly comply with these requirements. It has thus been proposed to combine electrical motors and passive devices in a hybrid actuator to cover a ...

Generic and Systematic Evaluation of Haptic Interfaces Based on Testbeds

Hannes Bleuler, Fei Wang, Evren Samur

The purpose of evaluation procedures is to achieve both qualitative and quantitative statements on haptic rendering realism and performance. Since a haptic interface provides an interaction between a user and a virtual environment, fidelity of a haptic int ...
