Analysing Pedestrian Traffic Around Public Displays
This paper presents a powerful approach to evaluating public technologies by capturing and analysing pedestrian traffic using computer vision. This approach is highly flexible and scales better than traditional ethnographic techniques often used to evaluate technology in public spaces. This technique can be used to evaluate a wide variety of public installations and the data collected complements existing approaches. Our technique allows behavioural analysis of both interacting users and non-interacting passers-by. This gives us the tools to understand how technology changes public spaces, how passers-by approach or avoid public technologies, and how different interaction styles work in public spaces. In the paper, we apply this technique to two large public displays and a street performance. The results demonstrate how metrics such as walking speed and proximity can be used for analysis, and how this can be used to capture disruption to pedestrian traffic and passer-by approach patterns
Understanding Public Evaluation: Quantifying Experimenter Intervention
Public evaluations are popular because some research
questions can only be answered by turning “to the wild.”
Different approaches place experimenters in different roles
during deployment, which has implications for the kinds of
data that can be collected and the potential bias introduced
by the experimenter. This paper expands our understanding
of how experimenter roles impact public evaluations and
provides an empirical basis to consider different evaluation
approaches. We completed an evaluation of a playful
gesture-controlled display – not to understand interaction at
the display but to compare different evaluation approaches.
The conditions placed the experimenter in three roles,
steward observer, overt observer, and covert observer, to
measure the effect of experimenter presence and analyse the
strengths and weaknesses of each approach
Enter the Circle: Blending Spherical Displays and Playful Embedded Interaction in Public Spaces
Public displays are used a variety of contexts, from utility
driven information displays to playful entertainment displays.
Spherical displays offer new opportunities for interaction
in public spaces, allowing users to face each other
during interaction and explore content from a variety of
angles and perspectives. This paper presents a playful installation
that places a spherical display at the centre of a
playful environment embedded with interactive elements.
The installation, called Enter the Circle, involves eight
chair-sized boxes filled with interactive lights that can be
controlled by touching the spherical display. The boxes are
placed in a ring around the display, and passers-by must
“enter the circle” to explore and play with the installation.
We evaluated this installation in a pedestrianized walkway
for three hours over an evening, collecting on-screen logs
and video data. This paper presents a novel evaluation of a
spherical display in a public space, discusses an experimental
design concept that blends displays with embedded
interaction, and analyses real world interaction with the
installation

Disclosure in lesbian, gay and bisexual cancer care: towards a salutogenic healthcare environment
open access articleBackground: The literature on sexual orientation disclosure is arguably one of the most developed in the field of lesbian, gay and bisexual (LGB) people in healthcare in English speaking countries however, relatively little research has been conducted into disclosure in cancer care. Studies have been mainly undertaken in primary care where distinct circumstances pertain and where the benefits of disclosure include obtaining appropriate health information, treatment advice and avoiding misdiagnosis.
Methods: We conducted an in-depth qualitative study primarily recruiting patients through oncology care in
hospital settings and through LGB community cancer support groups. Data were gathered through semi-structured interviews with 30 LGB patients with different cancer types.
Results: Data were analysed using thematic analysis and interpreted and interrogated through salutogenesis theory which offers a useful lens through which to consider the health promoting effects of sexual orientation disclosure in cancer care. We present three themes as part of the analysis: Authenticity as a driver for disclosure in cancer care, Partners as a (potential) salutogenic resource and Creating safe, healing environments conducive to disclosure. The findings are reported and discussed in relation to three inter-related concepts from current salutogenesis theorising including a sense of coherence, generalised resistance resources and healing environments which can facilitate sexual orientation disclosure.
Conclusion: Our findings enable a more nuanced approach to understanding disclosure in this context. This study contributes to the literature through its articulation of the salutogenic potential of disclosure (if responded to appropriately) for LGB patients as individuals, in relationship to their partners or carers and the role of creating a visible healing-oriented optimal environment to promote quality of life and recovery
Playlab: Telling Stories with Technology (workshop summary)
This one-day workshop explores how playful interaction can be used to develop technologies for public spaces and create temporal experiences
Levitate: Interaction with Floating Particle Displays
This demonstration showcases the current state of the art for the levitating particle display from the Levitate Project. In this demonstration, we show a new type of display consisting of floating voxels, small levitating particles that can be positioned and moved independently in 3D space. Phased ultrasound arrays are used to acoustically levitate the particles. Users can interact directly with each particle using pointing gestures. This allows users to walk-up and interact without any user instrumentation, creating an exciting opportunity to deploy these tangible displays in public spaces in the future. This demonstration explores the design potential of floating voxels and how these may be used to create new types of user interfaces
GlobalFestival: Evaluating Real World Interaction on a Spherical Display
Spherical displays present compelling opportunities for interaction in public spaces. However, there is little research into how touch interaction should control a spherical surface or how these displays are used in real world settings. This paper presents an in the wild deployment of an application for a spherical display called GlobalFestival that utilises two different touch interaction techniques. The first version of the application allows users to spin and tilt content on the display, while the second version only allows spinning the content. During the 4-day deployment, we collected overhead video data and on-display interaction logs. The analysis brings together quantitative and qualitative methods to understand how users approach and move around the display, how on screen interaction compares in the two versions of the application, and how the display supports social interaction given its novel form factor
Levitating Particle Displays with Interactive Voxels
Levitating objects can be used as the primitives in a new type of display. We present levitating particle displays and show how research into object levitation is enabling a new way of presenting and interacting with information. We identify novel properties of levitating particle displays and give examples of the interaction techniques and applications they allow. We then discuss design challenges for these displays, potential solutions, and promising areas for future research
