The Effect of Feedback on Chord Typing

Pierre Dillenbourg, Bixio Rimoldi, Adrian Dan Tarniceriu

The amount of visual feedback when using a mobile device in a busy context is often limited. For example, while texting and walking in a crowded place, we need to focus on the environment and not on the phone. A way to type fast, accurately and with limite ...

Brain-machine interface control using broadband spectral power from local field potentials

Michael Christoph Gastpar

Recent progress in brain-machine interfaces (BMIs) has shown tremendous improvements in task complexity and degree of control. In particular, closed-loop decoder adaptation (CLDA) has emerged as an effective paradigm for both improving and maintaining the ...

Single-Handed Typing with Minimal Eye Commitment: A Text-Entry Study

Pierre Dillenbourg, Bixio Rimoldi, Adrian Dan Tarniceriu

For most people, typing text on a mobile device requires visual commitment to the input mechanism. As a consequence, there are many situations in our daily life when we have to refrain from using these devices as our vision is already committed. An example ...

Continuous decoding of grasping tasks for a prospective implantable cortical neuroprosthesi

Silvestro Micera

Background: In the recent past several invasive cortical neuroprostheses have been developed. Signals recorded from the motor cortex (area MI) have been decoded and used to control computer cursors and robotic devices. Nevertheless, few attempts have been ...

A Hall sensor microsystem with continuous gain calibration using fully integrated references

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents an integrated Hall sensor microsystem with continuous gain calibration and a current-mode back-end. The integrated system includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain, a voltage-to-c ...

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 ...

A fully integrated Hall sensor microsystem with current-mode output

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a fully integrated Hall sensor microsystem with a current-mode output. The system operates in open-loop and includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain and a voltage-to-current conv ...

An Improved Technique to Discover Compromising Electromagnetic Emanations

Martin Vuagnoux, Sylvain Pasini

The techniques generally used to detect compromising emanations are based on a wide-band receiver tuned on a specific frequency or a spectral analyzer with a limited bandwidth. However, these methods may not be optimal since a significant amount of informa ...

PC-Keyboard with force feedback: Sensorless position detection by current measurement

Martin Stöck

Grégory Savioz is working in collaboration with Logitech. The goal of his work is to develop a "haptique" keyboard. A functional prototype of one key was already realized. Till now a hall sensor was used to measure the position of the key. The prototype co ...

Computer Aided Cryptanalysis from Ciphers to Side Channels

Martin Vuagnoux

In this dissertation, we study the security of cryptographic protocols and cryptosystems from the mathematical definition of the primitives, up to their physical implementations in the real world. We propose a representation of the chronological design usi ...
