Exploring whole body interaction and design for museums

Museums increasingly use digital technology to enhance exhibition experiences for families, notably in relation to physically mediated installations for young children through natural user interfaces. Yet little is known about how families and children engage with such installations and the kinds of interactive experiences they engender in museum spaces. This paper addresses a pressing need for research to adopt an analytical focus on the body during such digitally mediated interactions in order to understand how bodily interaction contributes to meaning making in the museum context. It reports an observation study of families and children interacting with a whole-body interface (using Kinect) in the context of an installation in a museum exhibit on rare Chinese paintings. The study shows how the installation design engenders particular forms of bodily interaction, collaboration and meaning making. It also contributes design insights into whole-body interaction installations in museums and public spaces

Mobile experiences of historical place: a multimodal analysis of emotional engagement

This article explores how to research the opportunities for emotional engagement that mobile technologies provide for the design and enactment of learning environments. In the context of mobile technologies that foster location-based linking, we make the case for the centrality of in situ real-time observational research on how emotional engagement unfolds and for the inclusion of bodily aspects of interaction. We propose that multimodal methods offer tools for observing emotion as a central facet of person–environment interaction and provide an example of these methods put into practice for a study of emotional engagement in mobile history learning. A multimodal analysis of video data from 16 pairs of 9- to 10-year-olds learning about the World War II history of their local Common is used to illustrate how students’ emotional engagement was supported by their use of mobile devices through multimodal layering and linking of stimuli, the creation of digital artifacts, and changes in pace. These findings are significant for understanding the role of digital augmentation in fostering emotional engagement in history learning, informing how digital augmentation can be designed to effectively foster emotional engagement for learning, and providing insight into the benefits of multimodality as an analytical approach for examining emotion through bodily interaction

Pre-Discovery Observations of Disrupting Asteroid P/2010 A2

Solar system object P/2010 A2 is the first-noticed example of the aftermath of a recently disrupted asteroid, probably resulting from a collision. Nearly a year elapsed between its inferred initiation in early 2009 and its eventual detection in early 2010. Here, we use new observations to assess the factors underlying the visibility, especially to understand the delayed discovery. We present prediscovery observations from the LINEAR telescope and set limits to the early-time brightness from SOHO and STEREO satellite coronagraphic images. Consideration of the circumstances of discovery of P/2010 A2 suggests that similar objects must be common, and that future all-sky surveys will reveal them in large numbers.Comment: 22 pages, 8 figures; http://www2.ess.ucla.edu/~jewitt/P2010A2_f.htm

Migration of Jupiter-family comets and resonant asteroids to near-Earth space

We estimated the rate of comet and asteroid collisions with the terrestrial planets by calculating the orbits of 13000 Jupiter-crossing objects (JCOs) and 1300 resonant asteroids and computing the probabilities of collisions based on random-phase approximations and the orbital elements sampled with a 500 yr step. The Bulirsh-Stoer and a symplectic orbit integrator gave similar results for orbital evolution, but sometimes give different collision probabilities with the Sun. A small fraction of former JCOs reached orbits with aphelia inside Jupiter's orbit, and some reached Apollo orbits with semi-major axes less than 2 AU, Aten orbits, and inner-Earth orbits (with aphelia less than 0.983 AU) and remained there for millions of years. Though less than 0.1% of the total, these objects were responsible for most of the collision probability of former JCOs with Earth and Venus. Some Jupiter-family comets can reach inclinations i>90 deg. We conclude that a significant fraction of near-Earth objects could be extinct comets that came from the trans-Neptunian region.Comment: Proc. of the international conference "New trends in astrodynamics and applications" (20-22 January 2003, University of Maryland, College Park

Fast Rotation and Trailing Fragments of the Active Asteroid P/2012 F5 (Gibbs)

While having a comet-like appearance, P/2012 F5 (Gibbs) has an orbit native to the Main Asteroid Belt, and physically is a km-sized asteroid which recently (mid 2011) experienced an impulsive mass ejection event. Here we report new observations of this object obtained with the Keck II telescope on UT 2014 August 26. The data show previously undetected 200-m scale fragments of the main nucleus, and reveal a rapid nucleus spin with a rotation period of 3.24 $\pm$ 0.01 hr. The existence of large fragments and the fast nucleus spin are both consistent with rotational instability and partial disruption of the object. To date, many fast rotators have been identified among the minor bodies, which, however, do not eject detectable fragments at the present-day epoch, and also fragmentation events have been observed, but with no rotation period measured. P/2012 F5 is unique in that for the first time we detected fragments and quantified the rotation rate of one and the same object. The rapid spin rate of P/2012 F5 is very close to the spin rates of two other active asteroids in the Main Belt, 133P/Elst-Pizarro and (62412), confirming the existence of a population of fast rotators among these objects. But while P/2012 F5 shows impulsive ejection of dust and fragments, the mass loss from 133P is prolonged and recurrent. We believe that these two types of activity observed in the rapidly rotating active asteroids have a common origin in the rotational instability of the nucleus.Comment: To appear in the 2015 March 20 issue of ApJ Letter

Exploring methodological innovation in the social sciences: the body in digital environments and the arts

In this paper we examine methodological innovation in the social sciences through a focus on researching the body in digital environments. There are two strands to our argument as to why this is a useful site to explore methodological innovation in the social sciences. First, researching the body in digital environments places new methodological demands on social science. Second, as an area of interest at the intersection of the social sciences and the arts, it provides a focus for exploring how social science innovation can be informed by engagement with the arts, in this instance how the arts work with the body in digital environments and take up social science ideas in novel ways. We argue that social science engagement with the arts and the relatively unmapped terrain of the body in digital environments has the potential to open up spaces for innovative social science questions and methods: spaces, questions and methods that have potential for more general social science methodological innovation. We draw on the findings of the Methodological Innovation in Digital Arts and Social Sciences (MIDAS) project a multi-site ethnography of the research ecologies of the social sciences and the arts related to the body in digital environments. We propose a continuum of methodological innovation that attends to how methods are moved across research contexts and disciplines, in this instance the social sciences and the digital arts. We illustrate and discuss the innovative potential of expanding and re-situating methods across the social sciences and the arts, the transfer of methods and concepts across disciplinary borders and the interdisciplinary generation of new methods. We discuss the catalysts and challenges for social science methodological innovation in relation to the digital and the arts, with attention to how the social sciences might engage with the arts towards innovative research

The Orbit, Mass, and Albedo of Transneptunian Binary 1999 RZ253

We have observed 1999 RZ253 with the Hubble Space Telescope at seven separate epochs and have fit an orbit to the observed relative positions of this binary. Two orbital solutions have been identified that differ primarily in the inclination of the orbit plane. The best fit corresponds to an orbital period, P=46.263 +0.006/-0.074 days, semimajor axis a=4,660 +/-170 km and orbital eccentricity e=0.460 +/-0.013 corresponding to a system mass m=3.7 +/-0.4 x10^18 kg. For a density of rho = 1000 kg m^-3 the albedo at 477 nm is p = 0.12 +/-0.01, significantly higher than has been commonly assumed for objects in the Kuiper Belt. Multicolor, multiepoch photometry shows this pair to have colors typical for the Kuiper belt with a spectral gradient of 0.35 per 100 nm in the range between 475 and 775 nm. Photometric variations at the four epochs we observed were as large as 12 +/-3% but the sampling is insufficient to confirm the existence of a lightcurve

Irregular Satellites of the Planets: Products of Capture in the Early Solar System

All four giant planets in the Solar system possess irregular satellites, characterized by large, highly eccentric and/or inclined orbits that are distinct from the nearly circular, uninclined orbits of the regular satellites. This difference can be traced directly to different modes of formation. Whereas the regular satellites grew by accretion within circumplanetary disks the irregular satellites were captured from initially heliocentric orbits at an early epoch. Recently, powerful survey observations have greatly increased the number of known irregular satellites, permitting a fresh look at the group properties of these objects and motivating a re-examination of the mechanisms of capture. None of the suggested mechanisms, including gas-drag, pull-down, and three-body capture, convincingly fit the group characteristics of the irregular satellites. The sources of the satellites also remain unidentified.Comment: 51 pages, 17 figures, 5 tables, to appear in ARAA 200

Becoming in touch with industrial robots through ethnography

Touch is central to communication and social interaction. For both humans and robots touch is a mode through which they sense the world. A second wave of industrial robots is reshaping how touch operates within the labor process. Recent studies have turned their attention to the role of touch in Human-Robot Interaction (HRI). While these studies have produced useful knowledge in relation to the affective capacities of robotic touch, methods remain restrictive. This paper contributes to expanding research methods for the study of robotic touch. It reports on the design of an ongoing ethnography that forms part of the InTouch project. The interdisciplinary project takes forward a socially orientated stance and is concerned with how technologies shape the semiotic and sensory dimensions of touch in the 'real world'. We contend that these dimensions are key factors in shaping how humans and robots interact, yet are currently overlooked in the HRI community. This multi-sited sensory ethnography research has been designed to explore the social implications of robotic touch within industrial settings (e.g. manufacturing and construction)

Digital touch for remote personal communication: An emergent sociotechnical imaginary

This article makes legible emergent social imaginaries of digital touch for remote communication in personal relationships, with attention to digital touch interfaces. It draws on data from rapid prototyping research workshops with apprentice professionals embedded within digital communication. Touch is discussed with respect to four analytical themes: materiality, body, emplacement and temporality. We illustrate how participants’ past and present experiences and future visions of remote digital touch thread through these themes and weave together to form a hegemonic, emergent sociotechnical imaginary of digital touch. The article contributes to social debates within digital personal remote communication by foregrounding touch, the material and the sensorial. The article’s novel interdisciplinary framework (combining design-based rapid prototyping with a multimodal and multi-sensorial analysis within the frame of the sociotechnical imaginary) also contributes to methodology around future-facing phenomena, prior to the process of their solidification into material, political formations
