Visual Haptic Feedback for Training of Robotic Suturing.

Front Robot AI 2022 2;9:800232. Epub 2022 Feb 2.

IHU-Strasbourg, Institute of Image-Guided Surgery, Strasbourg, France.

Current surgical robotic systems are teleoperated and do not have force feedback. Considerable practice is required to learn how to use visual input such as tissue deformation upon contact as a substitute for tactile sense. Thus, unnecessarily high forces are observed in novices, prior to specific robotic training, and visual force feedback studies demonstrated reduction of applied forces. Read More

HaptoMapping: Visuo-Haptic Augmented Reality by Embedding User-Imperceptible Tactile Display Control Signals in a Projected Image.

IEEE Trans Vis Comput Graph 2021 Dec 29;PP. Epub 2021 Dec 29.

This paper proposes HaptoMapping, a projection-based visuo-haptic augmented reality (VHAR) system, that can render visual and haptic content independently and present consistent visuo-haptic sensations on physical surfaces. HaptoMapping controls wearable haptic displays by embedded control signals that are imperceptible to the user in projected images using a pixel-level visible light communication technique. The prototype system is comprised of a high-speed projector and three types of haptic devicesfinger worn, stylus, and arm mounted. Read More

Effects of visual and visual-haptic perception of material rigidity on reaching and grasping in the course of development.

Acta Psychol (Amst) 2021 Nov 6;221:103457. Epub 2021 Dec 6.

Department of Developmental Psychology, Justus-Liebig-University Giessen, Otto-Behaghel-Str. 10 F1, 35394 Giessen, Germany. Electronic address:

The development of material property perception for grasping objects is not well explored during early childhood. Therefore, we investigated infants', 3-year-old children's, and adults' unimanual grasping behavior and reaching kinematics for objects of different rigidity using a 3D motion capture system. In Experiment 1, 11-month-old infants and for purposes of comparison adults, and in Experiment 2, 3-year old children were encouraged to lift relatively heavy objects with one of two handles differing in rigidity after visual (Condition 1) and visual-haptic exploration (Condition 2).

Visual-haptic integration, action and embodiment in virtual reality.

Psychol Res 2021 Oct 28. Epub 2021 Oct 28.

School of Human Movement and Nutrition Sciences, The University of Queensland, St. Lucia, QLD, 4072, Australia.

The current generation of virtual reality (VR) technologies has improved substantially from legacy systems, particularly in the resolution and latency of their visual display. The presentation of haptic cues remains challenging, however, because haptic systems do not generalise well over the range of stimuli (both tactile and proprioceptive) normally present when interacting with objects in the world. This study investigated whether veridical tactile and proprioceptive cues lead to more efficient interaction with a virtual environment. Read More

BCI-Based Control for Ankle Exoskeleton T-FLEX: Comparison of Visual and Haptic Stimuli with Stroke Survivors.

Sensors (Basel) 2021 Sep 26;21(19). Epub 2021 Sep 26.

Department of Biomedical Engineering, Colombian School of Engineering Julio Garavito, Bogotá 111166, Colombia.

Brain-computer interface (BCI) remains an emerging tool that seeks to improve the patient interaction with the therapeutic mechanisms and to generate neuroplasticity progressively through neuromotor abilities. Motor imagery (MI) analysis is the most used paradigm based on the motor cortex's electrical activity to detect movement intention. It has been shown that motor imagery mental practice with movement-associated stimuli may offer an effective strategy to facilitate motor recovery in brain injury patients. Read More

Development of multisensory integration following prolonged early-onset visual deprivation.

Curr Biol 2021 11 16;31(21):4879-4885.e6. Epub 2021 Sep 16.

Applied Cognitive Psychology, Faculty for Computer Science, Engineering, and Psychology, Ulm University, Ulm 89081, Germany.

Adult humans make effortless use of multisensory signals and typically integrate them in an optimal fashion. This remarkable ability takes many years for normally sighted children to develop. Would individuals born blind or with extremely low vision still be able to develop multisensory integration later in life when surgically treated for sight restoration? Late acquisition of such capability would be a vivid example of the brain's ability to retain high levels of plasticity. Read More

Multisensory postural control in adults: Variation in visual, haptic, and proprioceptive inputs.

Hum Mov Sci 2021 Oct 3;79:102845. Epub 2021 Aug 3.

University of Toronto Scarborough, Canada. Electronic address:

Maintaining balance is fundamentally a multisensory process, with visual, haptic, and proprioceptive information all playing an important role in postural control. The current project examined the interaction between such sensory inputs, manipulating visual (presence versus absence), haptic (presence versus absence of contact with a stable or unstable finger support surface), and proprioceptive (varying stance widths, including shoulder width stance, Chaplin [heels together, feet splayed at approximately 60°] stance, feet together stance, and tandem stance) information. Analyses of mean velocity of the Centre of Pressure (CoP) revealed significant interactions between these factors, with stability gains observed as a function of increasing sensory information (e.

SPinPong - Virtual Reality Table Tennis Skill Acquisition using Visual, Haptic and Temporal Cues.

IEEE Trans Vis Comput Graph 2021 05 15;27(5):2566-2576. Epub 2021 Apr 15.

Learning an advanced skill in sports requires a huge amount of practice and players also have to overcome both physical difficulties and the dullness of repetitive training. Returning a fast spin shot in table tennis could be taken as an example, as athletes need to judge the spin type and decide the racket pose within a second, which is difficult for beginners. Therefore, in this paper, we show how to design an intuitive training system to acquire this specific skill using different cues in Virtual Reality (VR). Read More

Influence of action video gaming on spatial representation in the haptic modality.

Exp Brain Res 2020 Dec 29;238(12):2769-2781. Epub 2020 Sep 29.

Department of Cognitive Neuroscience, Faculty of Psychology and Neuroscience, Maastricht University, Maastricht, The Netherlands.

Spatial representation in the haptic domain has been shown to be prone to systematic errors. When participants are asked to make two bars haptically parallel, their performance deviates from what would be veridically parallel. This is hypothesized to be caused by the bias of the egocentric reference frame. Read More

Even distorted felt size engenders visual-haptic integration.

Atten Percept Psychophys 2020 Oct;82(7):3686-3695

Department of Psychological Sciences, Benedictine College, Atchison, KS, USA.

Intersensory interactions predicted by the sensory precision hypothesis have been infrequently examined by distorting the reliability of size perception by touch. Consequently, participants were asked to see one size and manually feel another unseen size either with bare fingers or with fingers sleeved in rigid tubes to decrease the precision of touch. Their subsequent visual estimates of the perceived size favored the more precise modality. Read More

Visual-Haptic Size Estimation in Peripersonal Space.

Front Neurorobot 2020 16;14:18. Epub 2020 Apr 16.

Human-Computer Interaction, Department of Informatics, Universität Hamburg, Hamburg, Germany.

In perceptual psychology, estimations of visual depth and size under different spatial layouts have been extensively studied. However, research evidence in virtual environments (VE) is relatively lacking. The emergence of human-computer interaction (HCI) and virtual reality (VR) has raised the question of how human operators perform actions based on the estimation of visual properties in VR, especially when the sensory cues associated with the same object are conflicting.

Can multisensory training aid visual learning? A computational investigation.

J Vis 2019 09;19(11)

Department of Computer Science, University of Rochester, Rochester, NY, USA.

Although real-world environments are often multisensory, visual scientists typically study visual learning in unisensory environments containing visual signals only. Here, we use deep or artificial neural networks to address the question, Can multisensory training aid visual learning? We examine a network's internal representations of objects based on visual signals in two conditions: (a) when the network is initially trained with both visual and haptic signals, and (b) when it is initially trained with visual signals only. Our results demonstrate that a network trained in a visual-haptic environment (in which visual, but not haptic, signals are orientation-dependent) tends to learn visual representations containing useful abstractions, such as the categorical structure of objects, and also learns representations that are less sensitive to imaging parameters, such as viewpoint or orientation, that are irrelevant for object recognition or classification tasks.

The Effect of Ageing on Optimal Integration of Conflicting and Non-Conflicting Visual-Haptic Stimuli.

Multisens Res 2019 12 11;32(8):771-796. Epub 2019 Dec 11.

2Division of Neuroscience and Experimental Psychology, Faculty of Biology, Medicine and Health, University of Manchester, UK.

Multisensory integration typically follows the predictions of a statistically optimal model whereby the contribution of each sensory modality is weighted according to its reliability. Previous research has shown that multisensory integration is affected by ageing, however it is less certain whether older adults follow this statistically optimal model. Additionally, previous studies often present multisensory cues which are conflicting in size, shape or location, yet naturally occurring multisensory cues are usually non-conflicting. Read More

How does ageing affect grasp adaptation to a visual-haptic size conflict?

Exp Brain Res 2018 08 23;236(8):2173-2184. Epub 2018 May 23.

Division of Neuroscience and Experimental Psychology, School of Biological Sciences, Faculty of Biology, Medicine and Health, The University of Manchester, Zochonis Building, Oxford Road, M13 9PL, Manchester, UK.

Previous research suggests that the ability to adapt motor behaviour to sudden environmental changes may be impaired in older adults. Here, we investigated whether the adaptation of grasping behaviour in response to a visual-haptic size conflict is also affected by increasing age. 30 older and 18 young adults were instructed to grasp a hidden block whilst viewing a second block in a congruent position.

NotifiVR: Exploring Interruptions and Notifications in Virtual Reality.

IEEE Trans Vis Comput Graph 2018 04;24(4):1447-1456

The proliferation of high resolution and affordable virtual reality (VR) headsets is quickly making room-scale VR experiences available in our homes. Most VR experiences strive to achieve complete immersion by creating a disconnect from the real world. However, due to the lack of a standardized notification management system and minimal context awareness in VR, an immersed user may face certain situations such as missing an important phone call (digital scenario), tripping over wandering pets (physical scenario), or losing track of time (temporal scenario).
