Chen, Gang (author), Dong, Wei (author), Peng, Peng (author), Alonso-Mora, J. (author), Zhu, Xiangyang (author)Particle-based dynamic occupancy maps were proposed in recent years to model the obstacles in dynamic environments. Current particle-based maps describe the occupancy status in discrete grid form and suffer from the grid size problem, wherein a large grid size is unfavorable for motion planning while a small grid size lowers efficiency and...journal article 2023

Liu, C. (author), Xu, Y. (author), van Kampen, E. (author), de Croon, G.C.H.E. (author)In this paper, we propose an obstacle avoidance solution for a 34-gram quadcopter equipped with a monocular camera. The perception of obstacles is tackled by a lightweight convolutional neural network predicting a dense depth map from a captured grey-scale image. The depth network performs self-supervised learning and thus requires no ground...journal article 2023

Zhao, Y. (author), Stumpel, J.F.H.J. (author), de Ridder, H. (author), Wijntjes, M.W.A. (author)Most studies on the perception of style have used whole scenes/entire paintings; in our study, we isolated a single motif (an apple) to reduce or even eliminate the influence of composition, iconography, and other contextual information. In this article, we empirically address two fundamental questions of the existence (Experiment 1) and...journal article 2023

de Winter, J.C.F. (author), Dodou, D. (author), Eisma, Y.B. (author)Raven matrices are widely considered a pure test of cognitive abilities. Previous research has examined the extent to which cognitive strategies are predictive of the number of correct responses to Raven items. This study examined whether response times can be explained directly from the centrality and visual complexity of the matrix cells ...journal article 2023

(author), Ibanez-Guzman, Javier (author), Li, Guofa (author), Piazzoni, Andrea (author), Wang, Pu (author), Santra, Avik (author)Automotive perception involves understanding the external driving environment and the internal state of the vehicle cabin and occupants using sensor data. It is critical to achieving high levels of safety and autonomy in driving. This article provides an overview of different sensor modalities, such as cameras, radars, and light detection and...journal article 2023

Gao, Yixuan (author), Song, Duanshu (author), Liu, Li (author), Huang, Y. (author)Affordances serve as design cues, facilitating users in effortlessly identifying the intended use of objects. However, due to the phenomenological nature of the affordance concept, its application and understanding in the human-computer interaction (HCI) domain remain uncertain, resulting in limited utilization in design practice. This study...journal article 2023

Ninan, Dr Johan (author), Yadav, Rupesh (author)Managing the perception of project communities is critical to the success of infrastructure megaprojects. This study focuses on the Nagpur metro rail project in India to understand people's experiences and discourses in the pre-construction, construction, and operation phases. We use qualitative content analysis and open coding of the tweets...journal article 2023

Howard, Thomas (author), Driller, K.K. (author), Frier, William (author), Pacchierotti, Claudio (author), Marchal, Maud (author), Hartcher-O'Brien, J. (author)Ultrasound mid-air haptic (UMH) devices are a novel tool for haptic feedback, capable of providing localized vibrotactile stimuli to users at a distance. UMH applications largely rely on generating tactile shape outlines on the users' skin. Here we investigate how to achieve sensations of continuity or gaps within such two-dimensional curves...journal article 2023

Post, Ruben A.G. (author), Blijlevens, Janneke (author), Hekkert, P.P.M. (author), Saakes, Daniel (author), Arango, Luis (author)Tactile experiences are a pivotal part of consumer behavior and choice. However, very little is known about why consumers esthetically appreciate touching products. The principle of Unity-in-Variety, stating that consumers like to perceive variety but only when this variety is presented as a coherent whole, has been shown to partly explain...journal article 2023

Peters, Luka (author), Serhat, Gokhan (author), Vardar, Y. (author)Thermal feedback has been proven to enhance user experience in human-machine interactions. Yet state-of-the-art thermal technology has focused on the single finger or palm in static contact, overlooking dynamic and multi-finger interactions. The underlying challenges include incompatible designs of conventional interfaces for providing...journal article 2023

Cheng, Gang (author), Wu, S. (author), Shi, M. (author), Dong, W. (author), Zhu, H. (author), Alonso-Mora, J. (author)Autonomous navigation of Micro Aerial Vehicles (MAVs) in dynamic and unknown environments is a complex and challenging task. Current works rely on assumptions to solve the problem. The MAV's pose is precisely known, the dynamic obstacles can be explicitly segmented from static ones, their number is known and fixed, or they can be modeled with...journal article 2023

Monnoyer, Jocelyn (author), Willemet, L. (author), Wiertlewski, M. (author)Shortly after touching an object, humans can tactually gauge the frictional resistance of a surface. The knowledge of surface friction is paramount to tactile perception and the motor control of grasp. While potent correlations between friction and participants' perceptual response have been found, the causal link between the friction of the...journal article 2023

Kodak, B.L. (author), Vardar, Y. (author)The ever-emerging mobile market induced a blooming interest in stylus-based interactions. Most state-of-the-art styluses either provide no haptic feedback or only deliver one type of sensation, such as vibration or skin stretch. Improving these devices with display abilities of a palette of tactile feels can pave the way for rendering...journal article 2023

Yuan, Y. (author), Wang, X. (author), Calvert, S.C. (author), Happee, R. (author), Wang, M. (author)Current driver behaviour models (DBMs) are primarily designed for the general driver population under specific scenarios, such as car following or lane changing. Hence DBMs capturing individual behaviour under various scenarios are lacking. This paper presents a novel method to quantify individual perceived driving risk in the longitudinal...journal article 2023
