Effects of stimulus order on auditory distance discrimination of virtual nearby sound sources

Authors: Simone Spagnol, Rebekka Hoffmann, Árni Kristjánsson, and Federico Avanzini in: The Journal of the Acoustical Society of America 141 Abstract: Stimulus order has been reported to affect perceived loudness. This letter investigates how temporal order affects distance discrimination of receding and approaching pairs of sound sources rendered binaurally in the anechoic near-field. Individual discrimination thresholds for different… Continue Reading Effects of stimulus order on auditory distance discrimination of virtual nearby sound sources

Relative vibrotactile spatial acuity of the torso

Authors: Ómar I. Jóhannesson, Rebekka Hoffmann, Vigdís Vala Valgeirsdóttir, Rúnar Unnþórsson, Alin Moldoveanu and Árni Kristjánsson in: Experimental Brain Research, November 2017 Abstract: While tactile acuity for pressure has been extensively investigated, far less is known about acuity for vibro-tactile stimulation. Vibrotactile acuity is important however, as such stimulation is used in many applications, including sensory substitution devices.… Continue Reading Relative vibrotactile spatial acuity of the torso

The Sound of Vision Project: On the Feasibility of an Audio-Haptic Representation of the Environment, for the Visually Impaired

Authors: Ómar I. Jóhannesson, Oana Balan, Runar Unnthorsson, Alin Moldoveanu and Árni Kristjánsson in: Brain Sci. 2016, 6, 20 Abstract: 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 is… Continue Reading The Sound of Vision Project: On the Feasibility of an Audio-Haptic Representation of the Environment, for the Visually Impaired

Evaluation of Human-Myo Gesture Control Capabilities in Continuous Search and Select Operations

Authors: Adam B. Csapo, Árni Kristjánsson, Hunor Nagy and György Wersényi in: 2017 Federated Conference on Computer Science and Information Systems Abstract: Tactile and haptic devices can be used to control and interact with a wide range of systems, including games, virtual environments and assistive technologies. Although many psychophysical studies have measured thresholds of human sensory capabilities for… Continue Reading Evaluation of Human-Myo Gesture Control Capabilities in Continuous Search and Select Operations
