  • Brinkhuis, M. A. B.; Brascamp, J. W.; Kristjansson, Arni (SAGE Publications, 2018-11)
    During visual search, selecting a target facilitates search for similar targets in the future, known as search priming. During bistable perception, in turn, perceiving one interpretation facilitates perception of the same interpretation in the future, ...
  • Spagnol, Simone; Hoffmann, Rebekka; Herrera Martínez, Marcelo; Unnthorsson, Runar (Elsevier BV, 2018-07)
    Translating visual representations of real environments into auditory feedback is one of the key challenges in the design of an electronic travel aid for visually impaired persons. Although the solutions currently available in the literature can lead ...
  • Kristjansson, Arni; Moldoveanu, Alin; Jóhannesson, Ómar I.; Bălan, Oana; Spagnol, Simone; Valgeirsdóttir, Vigdís Vala; Unnthorsson, Runar (IOS Press, 2016-09-21)
    An exciting possibility for compensating for loss of sensory function is to augment deficient senses by conveying missing information through an intact sense. Here we present an overview of techniques that have been developed for sensory substitution ...
  • Chetverikov, Andrey; Kuvaldina, Maria; MacInnes, W. Joseph; Jóhannesson, Ómar I.; Kristjansson, Arni (Springer Nature, 2018-01-23)
    People often miss salient events that occur right in front of them. This phenomenon, known as change blindness, reveals the limits of visual awareness. Here, we investigate the role of implicit processing in change blindness using an approach that ...
  • Hoffmann, Rebekka; Valgeirsdóttir, Vigdís Vala; Jóhannesson, Ómar I.; Unnthorsson, Runar; Kristjansson, Arni (Springer Nature, 2018-10-06)
    Vibrotactile displays can compensate for the loss of sensory function of people with permanent or temporary deficiencies in vision, hearing, or balance, and can augment the immersive experience in virtual environments for entertainment, or professional ...
  • Hugosdottir, Rosa; Mørch, Carsten Dahl; Andersen, Ole Kæseler; Helgason, Thordur; Arendt-Nielsen, Lars (Springer Science and Business Media LLC, 2019-09-14)
    Background Electrical stimulation is widely used in experimental pain research but it lacks selectivity towards small nociceptive fibers. When using standard surface patch electrodes and rectangular pulses, large fibers are activated at a lower threshold ...
  • Jóhannesson, Ómar I.; Hoffmann, Rebekka; Valgeirsdóttir, Vigdís Vala; Unnthorsson, Runar; Moldoveanu, Alin; Kristjansson, Arni (Springer Nature, 2017-08-30)
    While tactile acuity for pressure has been extensively investigated, far less is known about acuity for vibrotactile stimulation. Vibrotactile acuity is important however, as such stimulation is used in many applications, including sensory substitution ...
  • Hansmann-Roth, Sabrina; Chetverikov, Andrey; Kristjansson, Arni (Association for Research in Vision and Ophthalmology (ARVO), 2019-08-01)
    Objects have a variety of different features that can be represented as probability distributions. Recent findings show that in addition to mean and variance, the visual system can also encode the shape of feature distributions for features like color ...
  • Jóhannesson, Ómar I.; Bălan, Oana; Unnthorsson, Runar; Moldoveanu, Alin; Kristjansson, Arni (MDPI AG, 2016-06-27)
    The Sound of Vision project involves developing a sensory substitution device that is aimed at creating and conveying a rich auditory representation of the surrounding environment to the visually impaired. However, the feasibility of such an approach ...
  • Csapo, Adam; Spagnol, Simone; Herrera Martinez, Marcelo; Bujacz, Michał; Janeczek, Maciej; Ivanica, Gabriel; Wersényi, György; Moldoveanu, Alin; Unnthorsson, Runar (Audio Engineering Society, 2017-05-11)
    This paper focuses on auditory sensory substitution for providing visually impaired users with suitable information in both static scene recognition and dynamic obstacle avoidance. We introduce three different sonification models together with three ...
