Augmented Reality Views for Occluded Interaction

論文URL: https://doi.org/10.1145/3290605.3300676

論文アブストラクト: We rely on our sight when manipulating objects. When objects are occluded, manipulation becomes difficult. Such occluded objects can be shown via augmented reality to re-enable visual guidance. However, it is unclear how to do so to best support object manipulation. We compare four views of occluded objects and their effect on performance and satisfaction across a set of everyday manipulation tasks of varying complexity. The best performing views were a see-through view and a displaced 3D view. The former enabled participants to observe the manipulated object through the occluder, while the latter showed the 3D view of the manipulated object offset from the object's real location. The worst performing view showed remote imagery from a simulated hand-mounted camera. Our results suggest that alignment of virtual objects with their real-world location is less important than an appropriate point-of-view and view stability.

A Design Space for Gaze Interaction on Head-mounted Displays

論文URL: https://doi.org/10.1145/3290605.3300855

論文アブストラクト: 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 compelling potential of combining HMDs and gaze, a systematic analysis is missing. To fill this gap, we present the first design space for gaze interaction on HMDs. Our design space covers human depth perception and technical requirements in two dimensions aiming to identify challenges and opportunities for interaction design. As such, our design space provides a comprehensive overview and serves as an important guideline for researchers and practitioners working on gaze interaction on HMDs. We further demonstrate how our design space is used in practice by presenting two interactive applications: EyeHealth and XRay-Vision.

Personalising the TV Experience using Augmented Reality: An Exploratory Study on Delivering Synchronised Sign Language Interpretation

論文URL: https://doi.org/10.1145/3290605.3300762

論文アブストラクト: Augmented Reality (AR) technology has the potential to extend the screen area beyond the rigid frames of televisions. The additional display area can be used to augment televisions (TVs) with extra information tailored to individuals, for instance, the provision of access services like sign language interpretations. We invited 23 (11 in the UK, 12 in Germany) users of signed content to evaluate three methods of watching a sign language interpreted programme – one traditional in-vision method with signed programme content on TV and two AR-enabled methods in which an AR sign language interpreter (a 'half-body' version and a 'full-body' version) is projected just outside the frame of the TV presenting the programme. In the UK, participants were split 3-ways in their preferences while in Germany, half the participants preferred the traditional method followed closely by the 'half-body' version. We discuss our participants reasoning behind their preferences and implications for future research.

Egocentric Smaller-person Experience through a Change in Visual Perspective

論文URL: https://doi.org/10.1145/3290605.3300926

論文アブストラクト: This paper explores how human perceptions, actions, and interactions can be changed through an embodied and active experience of being a smaller person in a real-world environment, which we call an egocentric smaller person experience. We developed a wearable visual translator that provides the perspective of a smaller person by shifting the wearer's eyesight level down to their waist using a head-mounted display and a stereo camera module, while allowing for field of view control through head movements. In this study, we investigated how the developed device can modify the wearer's body representation and experiences based on a field study conducted at a nursing school and museums, and through lab studies. It was observed that the participants changed their perceptions, actions, and interactions because they are considered to have perceived themselves as being smaller. Using this device, designers and teachers can understand the perspectives of other people in an existing environment.
