Interacting with a group of people requires to direct the attention of the whole group, thus requires feedback about the crowd’s attention. In face-to-face interactions, head and eye movements serve as indicator for crowd attention. However, when interacting online, such indicators are not available. To substitute this information, gaze visualizati...

Webcam-based eye-tracking promises easy and quick data collection without the need for specific or additional eye-tracking hardware. This makes it especially attractive for educational research, in particular for modern formats, such as MOOCs. However, in order to fulfill its promises, webcam-based eye tracking has to overcome several challenges, m...

Pupil dilation may reveal the outcomes of binary decisions. Hereby, pupils dilate stronger for stimuli that are deemed targets by the beholder than for distractors. Respective findings are built on average pupil dynamics, aggregated over multiple trials and participants rather than on single trials. Further, the reported differences between targets...

Although our pupils slightly dilate when we look at an intended target, they do not when we look at irrelevant distractors. This finding suggests that it may be possible to decode the intention of an observer, understood as the outcome of implicit covert binary decisions, from the pupillary dynamics over time. However, few previous works have inves...

Augmented and virtual reality (AR/VR) has entered the mass market and, with it, will soon eye tracking as a core technology for next generation head-mounted displays (HMDs). In contrast to existing gaze interfaces, the 3D nature of AR and VR requires estimating a user's gaze in 3D. While first applications, such as foveated rendering, hint at the c...

Eye tracking is expected to become an integral part of future augmented reality (AR) head-mounted displays (HMDs) given that it can easily be integrated into existing hardware and provides a versatile interaction modality. To augment objects in the real world, AR HMDs require a three-dimensional understanding of the scene, which is currently solved...

In this demonstration we introduce VRSpinning, a seated locomotion approach based around stimulating the user's vestibular system using a rotational impulse to induce the perception of linear self-motion. Currently, most approaches for locomotion in VR use either concepts like teleportation for traveling longer distances or present a virtual motion...

Redirected walking (RDW) allows virtual reality (VR) users to walkinfinitely while staying inside a finite physical space through subtleshifts (gains) of the scene to redirect them back inside the volume.All prior approaches measure the feasibility of RDW techniquesbased on if the user perceives the manipulation, leading to rathersmall applicable g...

Current approaches for locomotion in virtual reality are either creating a visual-vestibular conflict, which is assumed to cause simulator sickness, or use metaphors such as teleportation to travel longer distances, lacking the perception of self motion. We propose VRSpinning, a seated locomotion approach based around stimulating the user's vestibu...

Mobile virtual reality (VR) head-mounted displays (HMDs) are steadily becoming part of people's everyday life. Most current interaction approaches rely either on additional hardware (e.g. Daydream Controller) or offer only a liMassachusetts Institute of Technologyed interaction concept (e.g. Google Cardboard). We explore a solution where a conventi...
