Encountered-Type Haptic Displays (ETHDs) provide haptic feedback by positioning a tangible surface for the user to encounter. This permits users freely eliciting with during virtual simulation. ETHDs differ from most of current devices which rely on an actuator always in contact user. article intends describe and analyze different research efforts carried out this field. In addition, analyzes ETHD literature concerning definitions, history, hardware, perception processes involved,...

In this article, we propose an approach towards infinite surface haptic display. Our approach, named ENcountered-Type ROtating Prop Approach (ENTROPiA) is based on a cylindrical spinning prop attached to robot's end-effector serving as encountered-type display (ETHD). This type of permits the users have unconstrained, free-hand contact with being provided by robotic device for users' encounter be touched. our sensation touching virtual given interaction technique that couples sliding...

We present "Alfred", a novel haptic paradigm for object manipulation in 3D immersive virtual reality (VR). It uses robotic manipulator to move tangible objects its workspace such that they match the pose of be interacted with. Users can then naturally touch, grasp and manipulate while feeling congruent realistic feedback from proxy. The proxies detach robot, allowing natural unconstrained environment (VE). When manipulated comes into contact with environment, acts as an encounter-type...

Encountered-Type Haptic Displays (ETHDs) represent a field of haptic displays with the premise not using any type actuator directly in contact user skin, thus providing an alternative integration virtual environments. In this paper, we present novel interaction techniques (ITs) dedicated to ETHDs. The aim at addressing issues commonly presented for these devices such as limited areas, lags and unexpected collisions user. First, our paper proposes design framework based on several parameters...

The Brain-Computer Interface (BCI) community is slowly moving towards users' involvement at the development phases of their research. However, dimensions regarding end-user approach and interaction design are still overlooked in community. In this paper we proposing a way to look deeper user for extracting aspects from context that could be vital an efficient design. A total 211 students higher education institution Mexico were asked information about social technological context, activities...

This paper summarizes results obtained in the identification of sandy geobodies that have potential gas accumulations an area Burgos Basin.

In this paper, we present the design of ten different 3D user interactions using passive haptics and embedded in an escape game scenario which users have to from a pyramid limited time. Our solution is innovative by its modularity, allowing with virtual objects tangible props manipulated either directly hands feet or indirectly through single prop held hand, order perform several environment (VE). We also propose navigation technique based on "impossible spaces" design, naturally walk...

Abstract The study area comprises an oil play with numerous opportunities, identifying sandstone sequences proven potential. main sequence was deposited in the Upper Miocene within a transitional environment (external neritic), resulting formation of bars deltaic facies and channels, which represents excellent quality lateral extension storage rock, but also complexity due to internal variability. trap is structural closure against faults, formed extensive tectonic regime giving rise normal...

In absence of haptic feedback, the perception contact with virtual objects can rapidly become a problem in extended reality (XR) applications. XR developers often rely on visual feedback to inform user and display information. However, as for today, there is no clear path how design assess such techniques. this paper, we propose space creation techniques meant represent surfaces XR. Based space, conceived set various techniques, including novel approaches based onomatopoeia inspired by...

We propose a set of stylized visual effects (VFX) meant to improve the sensation contact with objects in Augmented Reality (AR). Various graphical have been conceived, such as virtual cracks, wrinkles, or even onomatopoeias inspired by comics. The VFX are augment perception contact, either real objects, terms material properties location for instance. These can be combined pseudohaptics approach further increase range simulated physical touched materials. An illustrative setup based on...

Encountered-Type Haptic Displays (ETHDs) enable users to touch virtual surfaces by using robotic actuators capable of co-locating real and without encumbering with actuators. One the main challenges ETHDs is ensure that do not interfere VR experience avoiding unexpected collisions users. This paper presents a design space for safety techniques visual feedback make aware robot’s state thus reduce unintended potential collisions. The blocks compose this focus on what when displayed how it...

Towards the adaptation of Brain-Computer Interfaces (BCIs) from laboratories to real contexts, challenge providing an efficient interaction becomes more notorious. Current paradigms are adapted a technical perspective which suffices only fraction requirements control computational application with neural activity. For example, human aspects have been usually considered secondary factor in non-invasive BCI research community, what has resulted poor user process and system underperformance....

El objetivo de este trabajo es estudiar los efectos corticales sonidos binaurales para coadyuvar a la disminución del estrés estudiantes universitarios. Para el estudio, se reclutaron 18 voluntarios: 9 hombres y mujeres (edad 22.83 ± 1.13 años). Los voluntarios fueron divididos en dos grupos, control experimental. grupo resolvió un memorama, mientras que experimental lo era estimulado través binaurales. En ambos casos, midió actividad electroencefalográfica (EEG) 4 canales: TP9, TP10, AF7...

In the context of IEEE VR 2020 3DUI Contest entitled "Embodiment for Difference", this paper presents a application to highlight challenges that people with physical disabilities face on their daily life. Two-armed users are placed in world where normally have three arms, making them effectively physically disabled. The scenario takes user through process struggling everyday interactions (designed humans arms), then receiving third arm prosthesis and thus recovering some level autonomy....

The aim of this project was to compare the level modulation Electroencephalographic (EEG) activity achieved by naïve users under two paradigms: traditional (or Graz) and User-Centered Design (UCD), which represents a foundation concept methodology for anthropocentric perspective in Brain Computer Interfaces. Both approaches made use same motor task: imagination throwing out basketball into basket. task performed during online brain-computer communication. To quantify qualify EEG signals,...
