Abstract: Current head mounted displays (HMDs) cover only a small section of the user’s visual field, preventing the use of peripheral onset cues. This study investigates whether a centrally positioned cue can use the pursuit motion reflex to reorient attention away from HMDs more quickly than arrow cues. Thirty participants recruited from the University of Canterbury c us were required to find and mark targets which appeared within a 200° visual arc of a central focused position after being given no directional cue, an arrow cue or a pursuit motion cue. A subgroup of less than half of the participants failed to extract directional information from pursuit motion cues and the remaining participants responded more slowly to the pursuit cues than the arrow cues. Arrow cues were responded to only 40ms slower than targets appearing within the participants’ peripheral vision indicating that the search for a reflexive orientation cue may be unnecessary.

Abstract: Visual search performance was studied using auditory cues delivered over a bone conduction headset. Two types of auditory cues were employed to evaluate the effectiveness of such cues in an attention redirection task. Participants were required to locate and shoot targets at one of four locations on a screen when one of the two audio cues was delivered. Reaction and target acquisition times were significantly reduced when the binaurally spatialised cues were used compared to unlocalisable, monophonic cues. This appears to suggest that an auditory cue with directional information is far superior at aiding search tasks or alerting the user to redirect attention in the real-world space in comparison to a centered ‘monophonic’ cue. The results demonstrate the effectiveness of a binaurally spatialised, dynamic cue and point to its potential use in an information rich environment to provide useful and actionable information.

Abstract: Hyperscanning is a technique which simultaneously records the neural activity of two or more people. This is done using one of several neuroimaging methods, such as electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). The use of hyperscanning has seen a dramatic rise in recent years to monitor social interactions between two or more people. Similarly, there has been an increase in the use of virtual reality (VR) for collaboration, and an increase in the frequency of social interactions being carried out in virtual environments (VE). In light of this, it is important to understand how interactions function within VEs, and how they can be enhanced to improve their quality in a VE. In this paper, we present some of the work that has been undertaken in the field of social neuroscience, with a special emphasis on hyperscanning. We also cover the literature detailing the work that has been carried out in the human–computer interaction domain that addresses remote collaboration. Finally, we present a way forward where these two research domains can be combined to explore how monitoring the neural activity of a group of participants in VE could enhance collaboration among them.

Abstract: Attention redirection trials were carried out using a wearable interface incorporating auditory and visual cues. Visual cues were delivered via the screen on the Recon Jet – a wearable computer resembling a pair of glasses – while auditory cues were delivered over a bone conduction headset. Cueing conditions included the delivery of in idual cues, both auditory and visual, and in combination with each other. Results indicate that the use of an auditory cue drastically decreases target acquisition times. This is true especially for targets that fall outside the visual field of view. While auditory cues showed no difference when paired with any of the visual cueing conditions for targets within the field of view of the user, for those outside the field of view a significant improvement in performance was observed. The static visual cue paired with the binaurally spatialised, dynamic auditory cue appeared to provide the best performance in comparison to any other cueing conditions. In the absence of a visual cue, the binaurally spatialised, dynamic auditory cue performed the best.
