Summary: Developing motivational technology to support long-term behavior change is a
challenge. A solution is to incorporate insights from behavior change theory
and design technology to tailor to individual users. We carried out two studies
to investigate whether the processes of change, from the Transtheoretical
Model, can be effectively represented by motivational text messages. We
crowdsourced peer-designed text messages and coded them into categories based
on the processes of change. We evaluated whether people perceived messages
tailored to their stage of change as motivating. We found that crowdsourcing is
an effective method to design motivational messages. Our results indicate that
different messages are perceived as motivating depending on the stage of
behavior change a person is in. However, while motivational messages related to
later stages of change were perceived as motivational for those stages, the
motivational messages related to earlier stages of change were not. This
indicates that a person's stage of change may not be the (only) key factor that
determines behavior change. More individual factors need to be considered to
design effective motivational technology.

Summary: In our daily life everything and everyone occupies an amount of space,
simply by "being there". Edward Hall coined the term proxemics for the studies
of man's use of this space. This paper presents a study on proxemics in
Human-Robot Interaction and particularly on robot's approaching groups of
people. As social psychology research found proxemics to be culturally
dependent, we focus on the question of the appropriateness of the robot's
approach behavior in different cultures. We present an online survey (N=181)
that was distributed in three countries; China, the U.S. and Argentina. Our
results show that participants prefer a robot that stays out of people's
intimate space zone just like a human would be expected to do. With respect to
cultural differences, Chinese participants showed high-contact responses and
believed closer approaches were appropriate compared to their U.S.
counterparts. Argentinian participants more closely resembled the ratings of
the U.S. participants.

Summary: We address the possibilities of truly interactive systems for people with
Profound Intellectual and Multiple Disabilities (PIMD). These are intended to
improve alertness, movement and mood. We are working on an interactive ball
that follows body movement and an interactive floor mat for this target group.
We explain the key features in the design that are essential for the possible
success.

Summary: Gestures are important non-verbal signals in human communication. Research
with virtual agents and robots has started to add to the scientific knowledge
about gestures but many questions with respect to the use of gestures in
human-computer interaction are still open. This paper investigates the
influence of robot gestures on the users' perceived workload and task
performance (i.e. information recall) in a direction-giving task. We conducted
a 2 x 2 (robot gestures vs. no robot gestures x easy vs. difficult task)
experiment. The results indicate that robot gestures increased user performance
and decreased perceived workload in the difficult task but not in the easy
task. Thus, robot gestures are a promising means to improve human-robot
interaction particularly in challenging tasks.

Summary: This video details the development of an intelligent outdoor Guide robot.
The main objective is to deploy an innovative robotic guide which is not only
able to show information, but to react to the affective states of the users,
and to offer location-based services using augmented reality. The scientific
challenges concern autonomous outdoor navigation and localization, robust 24/7
operation, affective interaction with visitors through outdoor human and facial
feature detection as well as engaging interactive behaviors in an ongoing
non-verbal dialogue with the user.

Summary: In our previous work we introduced functional noise as a modality for robots
to communicate intent [6]. In this follow-up experiment, we replicated the
first study with a robot which was taller in order to find out if the same
results would apply to a tall vs. a short robot. Our results show a similar
trend: a robot using functional noise is perceived more positively compared
with a robot that does not.

Summary: Research has been carried out on robots approaching one person [1, 3, 4].
However, further research is needed on robots approaching groups of people. In
the study reported in this paper, we studied participants who were paired up
for a task and assessed their perception and behaviors as they were approached
by a robot from various angles. On an individual level, participants liked the
frontal approaches, and they disliked being approached from the back. However,
we found that the presence of a task-partner influenced participants' comfort
with a robot approaching (i.e. when the robot approaches and one is standing
behind the task-partner). Apart from the positioning of the individuals, the
layout of the room, position of furniture and doors, also seemed to influence
their experience. This pilot study was performed with a limited number of
participants (N=30). However, the study offers preliminary insights into the
factors that influence the choice for a robot approach direction when
approaching a pair of people that are focused on a task.

Summary: Robots have recently started to leave their safety cages to be used in close
vicinity to humans. This also causes changes in the nature of the tasks that
robots and humans solve together, i.e., in the degree of structure of the
tasks. While traditional, industrial tasks were highly structured, the new
tasks often have a low level of structure. We present a user study that
compares a highly and a little structured task in a text-based computer game
played by human-robot teams. The results suggest that users do not only find
robots useful and motivating in highly structured tasks where they depend on
their help, but also in little structured tasks that they could solve on their
own.

Summary: Being interrupted by notifications and reminders is common while working. In
this study we consider whether system politeness reduces (negative) effects of
being interrupted by system requests. We carried out a 2 (polite vs. neutral
system request) x 2 (high vs. low mental load) between-participants experiment.
We measured annoyance, frustration and mental effort. Our results suggest that
social strategies can mitigate some of the negative effects, but that this
depends on the difficulty of the task. We discuss the implications of these
results for the design of interruptive system messages and for further research
into social computing.

Summary: We report intermediate results of an ongoing study into the effectiveness of
robot gaze behaviors when addressing multiple persons. The work is being
carried out as part of the EU FP7 project FROG and concerns the design and
evaluation of interactive behaviors of a tour guide robot. Our objective is to
understand how to address and engage multiple visitors simultaneously. The
robot engages small groups of visitors in interaction and offers information on
objects of interest. In the current experiment, a robot tells three visitors
about two different paintings. A 2 X 2 independent factorial design is used.
The robot engages the three visitors in mutual gaze by looking at the artwork
while talking about it vs. only looking at the visitors (between
subject-groups). Also, the robot 'favors' one of the three participants by
directing it's gaze at them more frequently and longer compared to the other
two participants. We are interested to find out whether gaze at the object of
interest and favoring through gaze has an effect on the user's experience and
knowledge retention. Preliminary results indicate that a robot that engages
visitors in mutual gaze is seen as more humanlike and 'favoring' a person in a
small group positively influences attitudes toward the robot.

Summary: We carry out a set of experiments to assess collaboration between human
users and robots in a cross-cultural setting. This paper describes the study
design and deployment of a video-based study to investigate task-dependence and
cultural-background dependence of the personality trait attribution on a
socially interactive robot. In Human-Robot Interaction, as well as in
Human-Agent Interaction research, the attribution of personality traits towards
intelligent agents has already been researched intensively in terms of the
social similarity or complementary rule. We assume that searching the
explanation for personality trait attribution in the similarity and
complementary rule does not take into account important contextual factors.
Just like people equate certain personality types to certain professions, we
expect that people may have certain personality expectations depending on the
context of the task the robot carries out. Because professions have different
social meaning in different national culture, we also expect that these
task-dependent personality preferences differ across cultures. Therefore, we
suggest an experiment that considers the task-context and the
cultural-background of users.

Summary: When in a human environment, one might expect that a social robot would act
according to the social norms people expect of each other. When someone does
not adhere to a prevalent social norm, people usually feel threatened and
disturbed. Thus, insight is needed into what is perceived as socially normative
behavior for robots. We conducted an experiment in which an agent approached a
participant in order to determine the effect of personal space invasion. We
manipulated the agent-type (human/robot) and the approach speed (slow/fast) of
the agent towards the participant. Unexpectedly, our results show that the
participants displayed more compensatory behavior in the robot condition than
in the human condition. We consider this response toward personal space
invasion as indication that people react in a similar way to robots as they do
to humans, however with more intensity.

Summary: We propose a daylong workshop at CSCW2012 on the topic collaboration in
challenging and difficult environments, which are to our understanding all
contexts, which go beyond traditional working/office settings topic. Examples
for these environments can be the automotive context or the context of a
semiconductor factory, which show very specific contextual conditions and
therefore offer special research challenges: How to address all passengers in
the car, not only the driver? How to explore operator tasks in a cleanroom? How
could the long-term (social) collaboration of robots and humans be investigated
in privacy critical environments?

Summary: This paper reports ongoing research to inform the design of a social robot
to monitor levels of pollutant gasses in the air. Next to licensed
environmental agents and immobile chemical sensors, mobile technologies such as
robotic agents are needed to collect complaints and smell descriptions from
humans in urban industrial areas. These robots will interact with members of
the public and ensure responsiveness and accuracy of responses. For robots to
be accepted as representative environmental monitoring agents and for people to
comply with robot instructions in the case of a calamity, social skills will be
important. In this paper we will describe the intelligent environment the
environmental robot is part of and discuss preliminary work to understand in
what way robot interruptions can be mitigated with help of social robot
behaviors.

Summary: Motivation -- This paper describes our work in progress to develop a
personal monitoring system that can monitor the physical and emotional
condition of a patient by using contextual information from a sensor network,
provide the patient with feedback concerning their health status and motivate
the patient to adopt behavior with a positive health impact (such as exercising
or taking medication at the right moment).
Research approach -- We will extend the capabilities of an existing robotic
health buddy with a (DBN based) sensor network. Then we will carry out a series
of controlled, long-term field experiments where we identify and evaluate the
effects of various agent social communicative behaviours on the user's adoption
of health improving lifestyle patterns.
Findings/Design -- The findings of the experiments will inform the final
design of the health buddy and it's behaviours. We will also realise system
adaptivity of the data processing and data fusion methods as well as the health
buddy adaptivity to the user's emotional state.
Research limitations/Implications -- The project will limit itself to
monitoring and motivating people who suffer from cardiovascular chronic
conditions and to the home environment.
Originality/Value -- The research makes a contribution to the needs of
health monitoring for a specific user group. The health buddy will use social
behaviours to motivate users over a long-term time period.
Take away message -- Home health monitoring and self care can be more
enjoyable and easier through motivating smart health buddies.

Summary: We present ongoing research concerning the interaction between users and
environmental agencies through autonomous mobile agents in the environmental
monitoring domain. The overarching EU FP7 project DIADEM, concerns the
development of a system that detects potentially hazardous situations in
populated areas using input from both a distributed sensor network and humans
through their mobile devices. We propose a model of interaction with a system
where concerned citizens communicate with a social virtual agent through their
mobile phone to inform the environmental monitoring agency about unusual
smells. In case of an emergency, people will receive instructions or directions
for evacuation from the agent. In this paper, we review relevant literature and
describe the development of a dynamic dialogue agent that supports
international collaboration by adapting its social interaction to the cultural
background of the humans it interacts with.

Summary: Mobile services can provide users with information relevant to their current
circumstances. Distant services in turn can acquire local information from
people in an area of interest. Socially expressive agent behaviour has been
suggested as a way to build reciprocal relationships and to increase user
response to such requests. This between-subject, Wizard-of-Oz experiment aimed
to investigate the potential of such behaviours. 44 participants performed a
search task in an urgent context while being interrupted by a mobile agent that
both provided and requested information. The socially expressive behaviour
shown in this study did not increase compliance to requests; it instead reduced
trust in provided information and compliance to warnings. It also negatively
impacted the affective experience of users scoring lower on empathy as a
personality trait. Inappropriate social expressiveness can have serious
consequences; we here elaborate on the reasons for our negative results.
