Immediate effects of short-duration wellbeing practices on children’s handwriting and posture guided by a social robot

Pierre Dillenbourg, Chenyang Wang, Barbara Bruno, Daniel Carnieto Tozadore, Melike Cezayirlioglu

Handwriting practising, as any other repetitive task, often leads the practiser to an overconcentration state where their performance might be affected by postural and mental fatigue. Short breaks to perform unrelated activities, especially relaxation exer ...

An Empirical and Subjective Model of Upper Extremity Fatigue Under Hypogravity

Volker Gass, Claude Nicollier, Tatiana Maillard

In the context of extra-terrestrial missions, the effects of hypogravity (0 < G < 1) on the human body can reduce the well-being of the crew, cause musculoskeletal problems and affect their ability to perform tasks, especially during long-term missions. To ...

Challenges and Opportunities in Integrating Interactive Chatbots into Code Review Exercises: A Pilot Case Study

Denis Gillet, Juan Carlos Farah, Adrian Christian Holzer

While chatbots are commonly used to support software developers with repetitive tasks, their use in programming education is still limited, particularly for students in non-technical domains. To better understand the potential for chatbots to support progr ...

Biomechanics at the workplace under hypogravity conditions

Tatiana Maillard

The main goal of my research is to establish guidelines for workplace design based on human biomechanics: specifically sitting workplaces and handling areas in 1/6G-1/3G (Moon, Mars) conditions. Such a workplace could be used in long-term space missions in ...

Highly Stretchable Silicone Elastomer Applied in Soft Actuators

Fabio Beco Albuquerque, Pengpeng Hu

In this work, a highly stretchable silicone elastomer is incorporated into dielectric elastomer actuators (DEAs) in order to decrease operation voltages by applying high prestretches. Results show that the fabricated DEAs (5 mm diameter circle active regio ...

Fabrication of moire on curved surfaces

Roger Hersch, Vahid Babaei

Moire is an appealing visual effect observable when two or more repetitive patterns are superposed. Fabrication of moire effects has already proven to be useful in a range of applications, from art to engineering. Here, we introduce a method for designing ...

Design of Dynamic Tangible Workspaces for Games: Application on Robot-Assisted Upper Limb Rehabilitation

Pierre Dillenbourg, Arzu Güneysu Özgür, Barbara Bruno, Ayberk Özgür

A key element for the success of any game is its ability to produce a different experience at each round, thus keeping the player engagement high. This is particularly important for those games that also have a serious objective, such as gamified rehabilit ...

Iterative learning control for trajectory tracking of a parallel Delta robot

Mohamed Bouri

This paper proposes an iterative learning controller (ILC) under the alignment condition for trajectory tracking of a parallel Delta robot, that performs various repetitive tasks for palletization. Motivated by the high cadence of our application that lead ...

Ergonomic handle for haptic devices

Hannes Bleuler, Ricardo Daniel Rita Beira

A ergonomic handle that can be added to existing haptic devices, composed by a spherical mechanism providing hand orientation and a grasping mechanism is shown. Both the proposed spherical mechanism and the handle have been ergonomically designed to avoid ...

Combining Geometric and Appearance Priors for Robust Homography Estimation

Pascal Fua, Vincent Lepetit, Mustafa Özuysal

The homography between pairs of images are typically computed from the correspondence of keypoints, which are established by using image descriptors. When these descriptors are not reliable, either because of repetitive patterns or large amounts of clutter ...

A Miniature Short Stroke Actuator and its Position Control for a Haptic Key

Yves Perriard, Grégory Savioz

This paper addresses the design and optimization of a small-sized linear electrodynamic actuator. This actuator is aimed to be inserted under a computer key in order to produce a force feedback to the user. Replacing the current rubber dome supporting the ...

Pose Priors for Simultaneously Solving Alignment and Correspondence

Pascal Fua, Vincent Lepetit

Estimating a camera pose given a set of 3D-object and 2D-image feature points is a well understood problem when correspondences are given. However, when such correspondences cannot be established a priori, one must simultaneously compute them along with th ...

A Statistical Analysis of Certain Iterative Learning Control Algorithms

Alireza Karimi, Roland Longchamp, Mark Edward John Butcher

Iterative Learning Control (ILC) is a technique used to improve the tracking performance of systems carrying out repetitive tasks, which are affected by deterministic disturbances. The achievable performance is greatly degraded, however, when non-repeating ...
