Mirror, Mirror, On The Wall: Collaborative Screen-Mirroring for Small Groups
Screen mirroring has been available to consumers for some time, however if every mobile device in the room supports screen mirroring to the main display (e.g. a shared TV), this necessitates a mechanism for managing its use. As such, this paper investigates allowing users in small intimacy groups (friends, family etc.) to self-manage mirrored use of the display, through passing/taking/requesting the display from whomever is currently mirroring to it. We examine the collaborative benefits this scheme could provide for the home, compared to existing multi-device use and existing screen mirroring implementations. Results indicate shared screen mirroring improves perceived collaboration, decreases dominance, preserves independence and has a positive effect on a group's activity awareness
I Am The Passenger: How Visual Motion Cues Can Influence Sickness For In-Car VR
This paper explores the use of VR Head Mounted Displays
(HMDs) in-car and in-motion for the first time. Immersive
HMDs are becoming everyday consumer items and, as they
offer new possibilities for entertainment and productivity, people
will want to use them during travel in, for example, autonomous
cars. However, their use is confounded by motion
sickness caused in-part by the restricted visual perception
of motion conflicting with physically perceived vehicle motion
(accelerations/rotations detected by the vestibular system).
Whilst VR HMDs restrict visual perception of motion, they
could also render it virtually, potentially alleviating sensory
conflict. To study this problem, we conducted the first on-road
and in motion study to systematically investigate the effects
of various visual presentations of the real-world motion of
a car on the sickness and immersion of VR HMD wearing
passengers. We established new baselines for VR in-car motion
sickness, and found that there is no one best presentation
with respect to balancing sickness and immersion. Instead,
user preferences suggest different solutions are required for
differently susceptible users to provide usable VR in-car. This
work provides formative insights for VR designers and an entry
point for further research into enabling use of VR HMDs,
and the rich experiences they offer, when travelling
Work-In-Progress Technical Report: Designing A Two-User, Two-View TV Display
This work-in-progress paper previews how we can design interfaces
and interactions for multi-view TVs, enabling users
to transition between independent and shared activities, gain
casual awareness of othersâ activities, and collaborate more
effectively. We first compare an Android-based multi-user
TV against both multi-screen and multi-view TVs in a collaborative
movie browsing task, to determine whether multiview
can improve collaboration, and what level of awareness
of each otherâs activity users choose. Based on our findings,
we iterate on our multi-view design in a second study, giving
users the ability to transition between casual and focused
modes of engagement, and dynamically set their engagement
with other usersâ activities. This research demonstrates that
the shared focal point of the TV now has the capability to
facilitate both collaborative and completely independent activity
Ion implantation damage of silicon as observed by optical reflection spectroscopy in the 1 to 6 eV region
Optical reflection spectra of crystalline, sputtered, and ion implanted silicon specimens are presented. Characteristic aspects of the spectra of ion implanted specimens are related to lattice damage
A national UK survey of peripatetic support teams for children and adults with intellectual and developmental disability who display challenging behaviour
Background: The service provision model of peripatetic support teams for people with intellectual disabilities who present challenging behaviour has been well established in the United Kingdom, with a small but growing evidence base. The current context in the UK would appear to indicate an ever-increasing role for such teams, in order to support people in their own communities and reduce the reliance on out-of-area placements. This study sought to establish the current position of such teams within the UK.
Method and materials: 46 teams were given the opportunity to complete an online questionnaire regarding the team's day to day functioning.
Results: 20 services responded to the survey providing a range of data. The results suggested that the services were mainly targeted towards adults, had a range of working practices and therapeutic orientations, with broadly successful outcomes (albeit self reported). The data would also suggest that this type of provision had diminished in recent years.
Conclusions: The implications of the survey are discussed within the context of the current policy in the UK. In particular, the lack of provision for children, the use of evidence based practice and what appears to be a diminishing resource just at the time when it is most needed are explored
I Am The Passenger: Challenges in Supporting AR/VR HMDs In-Motion
This video provides an overview of our research into the use of Head Mounted Displays (HMDs) in-car and in-motion. These immersive HMDs offer new possibilities for entertainment and productivity during travel. However, their use is confounded by motion sickness, caused in-part by the conflict between visually and physically perceived motion. Moreover, consumer HMDs cannot currently distinguish between the head motion of the wearer and rotations of the car. These problems represent significant impediments to their use in-motion, which our research aims to overcome
How Visual Motion Cues Can Influence Sickness For In-Car VR
This video demonstrates our research into the use of VR Head Mounted Displays (HMDs) in-car and in-motion. Immersive HMDs offer new possibilities for entertainment and productivity during travel. However, their use is confounded by motion sickness, caused in-part by the conflict between visually and physically perceived motion. We examine how visual conveyance of motion affects motion sickness during in-car VR
Stable isotopes demonstrate intraspecific variation in habitat use and trophic level of nonâbreeding albatrosses
The nonâbreeding period is critical for restoration of body condition and selfâmaintenance in albatrosses, yet detailed information on diet and distribution during this stage of the annual cycle is lacking for many species. Here, we use stable isotope values of body feathers (δ13C, δ15N) to infer habitat use and trophic level of nonâbreeding adult Greyâheaded Albatrosses Thalassarche chrysostoma (n = 194) from South Georgia. Specifically, we: (1) investigate intrinsic drivers (sex, age, previous breeding outcome) of variation in habitat use and trophic level; (2) quantify variation among feathers of the same birds; and (3) examine potential carryâover effects of habitat use and trophic level during the nonâbreeding period on subsequent breeding outcome. In agreement with previous tracking studies, δ13C values of individual feathers indicate that nonâbreeding Greyâheaded Albatrosses from South Georgia foraged across a range of oceanic habitats, but mostly in subantarctic waters, between the Antarctic Polar Front and Subtropical Front. Sex differences were subtle but statistically significant, and overlap in the core isotopic niche areas was high (62%); however, males exhibited slightly lower δ13C and higher δ15N values than females, indicating that males forage at higher latitudes and at a higher trophic level. Neither age nor previous breeding outcome influenced stable isotope values, and we found no evidence of carryâover effects of nonâbreeding habitat use or trophic level on subsequent breeding outcome. Repeatability among feathers of the same individual was moderate in δ13C and low in δ15N. This crossâsectional study demonstrates high variability in the foraging and migration strategies of this albatross population
Tunneling Currents and the E-k Relation
The energy-momentum dispersion relation within the forbidden gap of a single-crystal insulator (in this case, GaSe) has been accurately determined using a simple physical model to describe tunneling currents in appropriate thin-film structures. This dispersion relation, calculated from experimental current-voltage data, is shown to be intrinsic to GaSe and capable of quantitatively predicting tunneling currents. The work reported here represents the first quantitative calculation of tunneling currents in metal-insulator-metal structures with all parameters relevant to the experiment independently determined
