Abstract: When manipulating objects, humans begin adjusting their grip force to friction within 100 ms of contact. During motor adaptation, subjects become aware of the slipperiness of touched surfaces. Previously, we have demonstrated that humans cannot perceive frictional differences when surfaces are brought in contact with an immobilised...

A Role of Peripheral Vision in Chess? Evidence from a Gaze-contingent Method

de Winter, J.C.F. (author), Koelmans, T.A. (author), Kokshoorn, M.H.J.L. (author), van der Valk, K.P. (author), Vos, Willem (author), Dodou, D. (author), Eisma, Y.B. (author)

Chunking theory and previous eye-tracking studies suggest that expert chess players use peripheral vision to judge chess positions and determine the best moves to play. However, the role of peripheral vision in chess has largely been inferred rather than tested through controlled experimentation. In this study, we used a gaze-contingent paradigm...

Responses to Raven matrices: Governed by visual complexity and centrality

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 ...

Submillimeter lateral displacement enables friction sensing and awareness of surface slipperiness

Afzal, Hafiz Malik Naqash (author), Stubbs, Emma (author), Khamis, Heba (author), Loutit, Alastair J. (author), Redmond, Stephen (author), Vickery, Richard Martin (author), Wiertlewski, M. (author), Birznieks, Ingvars (author)

Human tactile perception and motor control rely on the frictional estimates that stem from the deformation of the skin and slip events. However, it is not clear how exactly these mechanical events relate to the perception of friction. This study aims to quantify how minor lateral displacement and speed enables subjects to feel frictional...

A Walk to the Cherwell River Meadows: (Meaningfulness and) the Perceivable Form of the Urban Landscape

de Wit, S.I. (author)

Meaningfulness in the urban landscape is guided by perception: the qualities of the environment only become meaningful if they can be experienced. Experiences are localized in the physical environment: the form of the (urban) landscape - which includes materiality as well as structure - creates the conditions, the organisation, of experience....

Unperceived motor actions of the balance system interfere with the causal attribution of self-motion

Tisserand, Romain (author), Rasman, Brandon G. (author), Omerovic, Nina (author), Peters, Ryan M. (author), Forbes, P.A. (author), Blouin, Jean Sébastien (author)

The instability of human bipedalism demands that the brain accurately senses balancing self-motion and determines whether movements originate from self-generated actions or external disturbances. Here, we challenge the longstanding notion that this process relies on a single representation of the body and world to accurately perceive postural...

The Social Acceptance of Airborne Wind Energy: A Literature Review

Schmidt, H.S. (author), de Vries, G. (author), Schmehl, R. (author), Renes, Reint Jan (author)

Airborne wind energy (AWE) systems use tethered flying devices to harvest higher-altitude winds to produce electricity. For the success of the technology, it is crucial to understand how people perceive and respond to it. If concerns about the technology are not taken seriously, it could delay or prevent implementation, resulting in increased...

Public Perceptions of Reuse of Faecal Sludge Co-Compost in Bhubaneswar, India

Singh, Shirish (author), Ibrahim, Mohammed Ali (author), Pawar, Sumeet (author), Brdjanovic, Damir (author)

Although faecal sludge (FS) co-compost contains vital nutrients, there are several barriers limiting adoption and reuse of FS co-compost in agriculture. This study in Bhubaneswar found that health risk and bad odour were the two topmost negative perceptions of FS co-compost reuse. The main factors influencing farmers’ negative perceptions of...

Finger motion and contact by a second finger influence the tactile perception of electrovibration

Vardar, Y. (author), Kuchenbecker, Katherine J. (author)

Electrovibration holds great potential for creating vivid and realistic haptic sensations on touchscreens. Ideally, a designer should be able to control what users feel independent of the number of fingers they use, the movements they make, and how hard they press. We sought to understand the perception and physics of such interactions by...

Leans Illusion in Hexapod Simulator Facilitates Erroneous Responses to Artificial Horizon in Airline Pilots

van den Hoed, Annemarie (author), Landman, H.M. (author), van Baelen, D. (author), Stroosma, O. (author), van Paassen, M.M. (author), Groen, Eric L. (author), Mulder, Max (author)

Objective: We tested whether a procedure in a hexapod simulator can cause incorrect assumptions of the bank angle (i.e., the “leans”) in airline pilots as well as incorrect interpretations of the attitude indicator (AI). Background: The effect of the leans on interpretation errors has previously been demonstrated in nonpilots. In-flight,...

Continuous Subjective Rating of Perceived Motion Incongruence During Driving Simulation

Cleij, D. (author), Venrooij, J. (author), Pretto, Paolo (author), Pool, D.M. (author), Mulder, Max (author), Bulthoff, Heinrich H. (author)

Motion cueing algorithms are used in motion simulation to map the inertial vehicle motion onto the limited simulator motion space. This mapping causes mismatches between the unrestricted visual motion and the constrained inertial motion, which results in perceived motion incongruence (PMI). It is still largely unknown what exactly causes...

Touching Materials Visually: About the Dominance of Vision in Building Material Assessment

Wastiels, L. (author), Schifferstein, H.N.J. (author), Wouters, I. (author), Heylighen, A. (author)

Designers’ visual way of knowing and working tends to be highly valued in design research. In architecture such an approach is increasingly criticized. Since people experience buildings with all their senses, architects’ visual focus is said to the run the risk of disregarding non-visual aspects. This study focuses on the visual and tactile...
