Perception-Action Loop for Multi-Robot Systems with Deep Learning
Perception-action loop is a fundamental concept in robotics that involves the iterative cycle of perceiving the environment and taking actions based on those perceptions. Various sensors and actuators are used in this process, and deep learning techniques have shown remarkable performance in …

EBBINGHAUS ILLUSION IN TOUCH AS EVIDENCE FOR THE TWO STREAM PERCEPTION-ACTION HYPOTHESIS
… stimulus (no illusion) is present in a tactile perception condition. Further, our results demonstrate that in a visual-tactile condition, the perceptual system is not deceived, even though the illusion deceives participants in both touch and vision alone. These results contribute to the …

Measurement technologies to enhance human capabilities via Mixed Reality
… end users with the best tools to enhance their perception-action loop in work or education, empowering them to better achieve and control their final goals. Through the synergy between immersive visualization technologies and a framework based on innovative measurement systems, unique …

Does Motor Attention Enhance Perception in Hemispatial Neglect?
… These findings support the hypothesis that perception–action coupling within interactive AR environments can help engage attentional networks that are less recruited during non-motor tasks. This pilot study provides preliminary evidence that motor engagement within an AR-based, game-like …

The Development of the Functional Dissociation of Perception and Action
… the ventral pathway, responsible for visual perception, and the dorsal pathway, which supports visuomotor actions. While the functional dissociation between these behaviours has been extensively studied in adults, its developmental trajectory and susceptibility to neurodevelopmental …

What spatial reference frame is used for priming in visual search?
The perception-action model proposes that vision for perception and vision for action are subserved by two separate cortical systems, the ventral and dorsal streams respectively (Milner & Goodale, 1995, 2006). It is argued that the dorsal stream codes spatial information egocentrically, that is, …

"Everything is a toxic competition" : how social interactions contribute to self-efficacy beliefs and resulting behavior in vocal divisions.
… as the dominant informant of one's self-perception, action, efforts, and achievements (Bandura, 1997). This study investigates the role self-belief plays in college music students' quest towards excellence in character and craft. Specifically, how do social interactions inform …

Distance Judgments for Joint Action: The Perceptual Consequences of Anticipated Coordination
<p>Recent perception research has revealed that judgments of distance are influenced by the energetic cost required to perform particular actions, such as walking, across these distances (Proffitt, 2006b). However, this prior research has focused almost exclusively on the perceptual consequences of …

Correspondence Between Haptic and Visual Perception of Stand-on-ability: Do Hills Look as Steep as they Feel?
… role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This …

Investigating motor skills of visually impaired young people and the use of sound to guide movements
… current thesis investigated this topic using a perception-action framework. <br/><br/>Four studies were conducted to assess the motor performance of visually impaired (VI) and sighted young people. Studies were designed to be close to the execution of object control and locomotor actions in …

Bottom-up and Top-down Mechanisms of Visually-Guided Movements
… we kept constant the visual stimuli and motor actions but manipulated the expectations of what subjects thought would happen. We found that visual perception systematically changes based on expectation, providing evidence for cognitive influences on visuomotor integration and continuity. Third, …

Robot Fleet Learning From Heterogeneous Data
… inputs and outputs due to the nature of the perception-action loops across diverse environments. The data format and distributions collected from these systems and used for training them are varied in different modalities such as color, depth, tactile, and proprioceptive information, and/or …

Ensemble : fluency and embodiment for robots acting with humans
… with the notion of fluency in human-robot interaction (HRI), exploring cognitive mechanisms for robotic agents that would enable them to overcome the stop-and-go rigidity present in much of HRI to date. We define fluency as the ethereal yet manifest quality existent when two agents perform …

Experience Dependent Sensorimotor Functioning in Adults with Severe Autism Spectrum Disorder
… (Chapter Three) was used to verify an intact perception-action link. In Chapter Four, in Twists, the trampolining group (those with sensorimotor experience) had a First Fixation Location on the incongruent model on the first trial but had a longer First Fixation Duration on the congruent model …

PRESERVED GRIP SCALING TO UNSEEN OBJECTS FOLLOWING A UNILATERAL LESION TO V1 FOR IMMEDIATE BUT NOT DELAYED GRASPING
Patients with damage to V1 can sometimes direct actions towards ‘unseen’ targets located in areas of the visual field that are deemed ‘blind’ on the basis of static perimetry tests. Here, we show that a patient with a complete right homonymous hemianopia after a V1 lesion remains sensitive to the …

The psychophysiological regulation of pacing behaviour and performance during prolonged endurance exercise
… how causeeffect relationships come to be and how perception-action coupling determines pacing behaviour and performance fatigability. A three-dimensional framework of centrally regulated and goal-directed exercise behaviour is proposed, which differentiates between sensory-discriminatory, …
