In teleoperation, and particularly when controlling semi-autonomous robots that need to be supervised during long tasks, the user can be easily distracted losing its situational awareness. In this paper, we compare three types of alert signals: haptic, visual and auditory, to determine whats the better way to get the pre-attention of the user in cr...

Phase-change phenomena are present in our daily life. Examples are the evaporation of a fluid when it reaches its boiling temperature, the condensation of water vapor in air due to the pressure changes or due to the difference of temperature in boundaries, and the melting of snow when winter is ending. Current development in physics-based animation...

Tangible objects are used in Virtual Reality (VR) and Augmented Reality (AR) to enhance haptic information on the general shape of virtual objects. However, they are often passive or unable to simulate rich varying mechanical properties. This paper studies the effect of combining simple passive tangible objects and wearable haptics for improving th...

Fatalities with semi-automated vehicles typically occur when users are engaged in non-driving related tasks (NDRTs) that compromise their situational awareness (SA). This work developed a tactile display for on-body notification to support situational awareness, thus enabling users to recognize vehicle automation failures and intervene if necessary...

Virtual reality is increasingly used for tasks such as work and education. Thus, rendering scenarios that do not interfere with such goals and deplete user experience are becoming progressively more relevant. We present a physiologically adaptive system that optimizes the virtual environment based on physiological arousal, i.e., electrodermal activ...
Conference Paper
Vibrotactile biofeedback can improve balance and consequently be helpful in fall prevention. However, it remains unclear how different types of stimulus presentations affect not only trunk tilt, but also Center of Pressure (CoP) displacements, and whether an instruction on how to move contributes to a better understanding of vibrotactile feedback.B...

Motor imagery Brain-Computer Interface (MI-BCI) enables bodyless communication by means of the imagination of body movements. Since its apparition , MI-BCI has been widely used in applications such as guiding a robotic prosthesis, or the navigation in games and virtual reality (VR) environments. Although psychological experiments, such as the Rubbe...
Conference Paper
Motor imagery Brain-Computer Interface (MI-BCI) is a paradigm widely used for controlling external devices by imagining bodily movements. This technology has inspired researchers to use it in several applications such as robotic prostheses, games, and virtual reality (VR) scenarios. We study the inclusion of an imaginary third arm as a part of the...
Conference Paper
Sketching was traditionally a 2D task. Even when the new generation of VR devices allowed to sketch in 3D, the drawn models remained essentially static representations. In this paper, we introduce a new physics-inspired sketching technique built on the top of Position-based Dynamics to enrich the 3D drawings with dynamic behaviors. A particle-based...
Conference Paper

In the context of the 3DUI Contest promoted by the IEEE VR 2018, we propose 3D interaction techniques that address three distinct tasks in a virtual environment setup: climbing a ladder, controlling a quadcopter in a first-person view flight, and building a tower by stacking a series of objects. The interaction techniques were developed so the play...

RESUMEN La Soldadura por Fricción-Agitación es un proceso empleado para la unión de metales, principalmente de baja tem-peratura de fusión, como aleaciones de aluminio. Los estudios que involucran la herramienta usada en este proceso de soldadura se centran principalmente en cuantificar el efecto que la geometría ejerce sobre las propiedades finale...
