Intercepting moving targets is a fundamental skill in human behavior, influencing various domains such as sports, gaming, and other activities. In these contexts, precise visual processing and motor control are crucial for adapting and navigating effectively. Nevertheless, there are still some gaps in our understanding…

Successfully intercepting a moving object requires precisely timing the optimal moment to act by integrating information about the target’s visual motion properties. Neurophysiological evidence indicates that activity in the primary motor cortex (M1) during interception preparation is sensitive to both the target’s…

'Aruul Mozhi Varman S' 'B. V. Vidyadhara' 'Mohitvishnu S. Gadde' 'Debasish Ghose' 'Raghu Krishnapuram'] Abstract Selective interception of objects in unknown environment autonomously by UAVs is an interesting problem. In this work, vision based interception is carried out. This problem is a part of challenge 1 of…

Capture Authors: ['Michal Pliska' 'Matouš Vrba' 'Tomáš Báča' 'Martin Saska'] Abstract—A unique approach for the mid-air autonomous aerial interception of non-cooperating Unmanned Aerial Vehicles by a flying robot equipped with a net is presented in this paper. A novel interception guidance method dubbed Fast Response…

In this study, we propose an algorithmic framework for solving a class of optimal control problems. This class is associated with the minimumtime interception of moving target problems, where a plant with a given state equation must approach a moving target whose trajectory is known a priori. Our framework employs an…

Interception, a fundamental visuomotor skill for activities such as driving and sports, involves two main strategies: predictive, anticipating the target’s trajectory, and prospective, actively tracking and adjusting movement. Experimentally controlled factors could potentially influence the relative usage of these…

Objects in our visual environment often move unpredictably and can suddenly speed up or slow down. The ability to account for acceleration when interacting with moving objects can be critical for survival. Here, we investigate how human observers track an accelerating target with their eyes and predict its time of…

Here we studied how participants steer to intercept uniformly moving targets in a virtual driving task. We tested the hypothesis that locomotor interception behavior cannot fully be explained by a strategy of nulling rate of change in pertinent agent-target relations such as the target-heading angle or target’s bearing…

Intercepting a moving target requires integrating visual motion information with motor preparation, yet how active motor preparation and gaze strategy jointly shape corticospinal excitability during interception planning remains unclear. We applied single-pulse transcranial magnetic stimulation over primary motor…

Multicopter Authors: ['Hailong Yan' 'Kun Yang' 'Yu‐Chieh Cheng' 'Zihao Wang' 'Dawei Li'] Abstract—Interception of low-altitude intruding targets with low-cost drones equipped strapdown camera presents a competitive option. However, the malicious maneuvers by the non-cooperative target and the coupling of the camera…

This paper presents the problem of lateral interception by a Dubins car of a target that moves along an a priori known trajectory. This trajectory is given by two coordinates of a planar location and one angle of a heading orientation, every one of them is a continuous function of time. The optimal trajectory planning…

Intercepting and avoiding collisions with moving targets are crucial skills for survival. However, little is known about how these behaviors are implemented when the trajectory of the moving target introduces variability and ambiguity into the perceptual-motor system. We developed a simple visuomotor task in which…

Directing our gaze towards a moving target has two known advantages for judging its trajectory: the spatial resolution with which the target is seen is maximized, and signals related to the eyes’ movements are combined with retinal cues to better judge the target’s motion. We here explore whether tracking a target with…

People can use the constant target-heading (CTH) strategy or the constant bearing (CB) strategy to guide their locomotor interception. But it is still unclear whether people can learn new interception behavior. Here, we investigated how people learn to adjust their steering to intercept targets faster. Participants…

'Cristina de la Malla'] In daily life we often interact with moving objects in tasks that involve analyzing visual motion, like catching a ball. To do so successfully we track objects with our gaze, using a combination of smooth pursuit and saccades. Previous work has shown that the occurrence and direction of…

Natural interception actions such as catching a ball require accurate motion prediction and typically involve multiple senses. Laboratory interception studies focus on vision and commonly ignore sound. Here we ask how visual and auditory signals are integrated to guide interception. Observers tracked the brief launch…

Human perception of space, time and motion is subject to several biases. Lab studies showed such effects in psychophysical judgements of location, but also in action-tasks, like predicting motion and intercepting. Given that similar underlying processes have been proposed for some of these biases, we tested for a…

For the law enforcement agencies, lawful interception is still one of the main means to intercept a suspect or address most illegal actions. Due to its centralized management, however, it is easy to implement in traditional networks, but the cost is high. In view of this restriction, this paper aims to exploit…

'Ali Dehghantanha'] Abstract Darknet technology such as Tor has been used by various threat actors for organising illegal activities and data exfiltration. As such there is a case for organisations to block such traffic, or to try and identify when it is used and for what purposes. However, anonymity in cyberspace has…

ATT&CK Authors: ['Marco Zambianco' 'Claudio Facchinetti' 'Domenico Siracusa'] Cyber deception allows compensating the late response of defenders countermeasures to the ever evolving tactics, techniques, and procedures (TTPs) of attackers. This proactive defense strategy employs decoys resembling legitimate system…

CCovalent inhibitors are being used more frequently in drug discovery and is expected to revolutionize how enzyme inhibitors and receptor modulators are created in the future. More than 30 covalent therapies have been approved by the US FDA as a result of this approach, which has produced a wide spectrum of effective…
