Publikováno v: 2020 IEEE Haptics Symposium (HAPTICS)
HAPTICS

In this paper we introduce a novel contact-free volumetric haptic feedback device. A symmetric electromagnet is used in combination with a dipole magnet model and a simple control law to deliver dynamically adjustable forces onto a hand-held tool. Th

Optimal control for electromagnetic haptic guidance systems

Autor: Thomas Langerak, Velko Vechev, David Lindlbauer, Otmar Hilliges, Daniele Panozzo, Juan Jose Zarate

We introduce an optimal control method for electromagnetic haptic guidance systems. Our real-time approach assists users in pen-based tasks such as drawing, sketching or designing. The key to our control method is that it guides users, yet does not t

A Demonstration on Dynamic Drawing Guidance via Electromagnetic Haptic Feedback

Autor: Daniele Panozzo, Juan Jose Zarate, Otmar Hilliges, Velko Vechev, Thomas Langerak

Publikováno v: UIST (Adjunct Volume)

We demonstrate a system to deliver dynamic guidance in drawing, sketching and handwriting tasks via an electromagnet moving underneath a high refresh rate pressure sensitive tablet presented in \citelangerak2019dynamic. The system allows the user to

Background The estimation of relative distance is a perceptual task used extensively in everyday life. This important skill suffers from biases that may be more pronounced when estimation is based on haptics. This is especially true for the blind and

Understanding Graphics on a Scalable Latching Assistive Haptic Display Using a Shape Memory Polymer Membrane

Autor: Herbert Shea, Luca Brayda, Nadine Besse, Juan Jose Zarate, Elisabetta Ferrari, Samuel Rosset

Publikováno v: IEEE transactions on haptics. 11(1)

We present a fully latching and scalable 4 × 4 haptic display with 4 mm pitch, 5 s refresh time, 400 mN holding force, and 650 μm displacement per taxel. The display serves to convey dynamic graphical information to blind and visually impaired user
