Multi-Finger Haptic Devices Integrating Miniature Short-Stroke Actuators

Grégory Savioz

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 ...

Self-sensing of linear short-stroke actuators for multi-finger haptic interfaces using induced high frequency oscillations

Yves Perriard, Grégory Savioz

With the aim of providing a new touch sensation to the user, the design of innovative multi-finger haptic devices passes through the research for efficient and low-cost methods for position sensing. This paper thus addresses a novel self-sensing method for ...

Compromising Electromagnetic Emanations of Wired and Wireless Keyboards

Martin Vuagnoux, Sylvain Pasini

Computer keyboards are often used to transmit confidential data such as passwords. Since they contain electronic components, keyboards eventually emit electromagnetic waves. These emanations could reveal sensitive information such as keystrokes. The techni ...

A Virtual Keyboard System based on Multi-Level Feature Matching

Edoardo Charbon, Huan Du

In this paper a Multi-Level Feature Matching (MLFM) method is presented for 3D hand posture reconstruction of a virtual keyboard system. The human hand is modeled with a mixture of different levels of detail, from skeletal to polygonal surface representati ...

Application of 3D range camera in virtual human-computer interfaces

Huan Du

In this work, we propose new ways to employ 3D-ranging systems in advanced human-computer interfaces and show that they can be used for precise hand-tracking systems aiming at virtual keyboard or mouse applications. We first implement a Structured Light (S ...

3D Hand Model Fitting for Virtual Keyboard System

Edoardo Charbon, Huan Du

In this paper, a 3D hand model fitting method is presented which can recover the accurate finger positions for a virtual keyboard system. The 3D hand model consists of a detailed polygonal skin driven by an underlying skeleton system. The system uses a str ...
