Summary: A number of digital platforms and services have recently emerged that allow
users to create posthumous forms of communication, effectively arranging for
the delivery of messages from "beyond the grave". Despite some evidence of
interest and popularity of these services, little is known about how posthumous
messages may impact the people who receive them. We present a qualitative study
that explores the type of experiences potentially triggered upon receiving such
messages. Our findings firstly suggest that posthumous messaging services have
the potential to alter the relationship between the bereaved and the deceased,
and secondly provide insight into how users make sense of this altered
relationship. Through the inference of a set of design considerations for
posthumous communication services, we reveal a number of conflicts that are not
easily solvable through technological means alone, and which may serve as
starting points for further research. Our work extends the growing body of
research that is concerned with digital interactions related to death and
dying.

Summary: This paper describes a system developed for a mobile service robot which
detects and tracks the position of a user's face in 3D-space using a vision
(skin color) and a sonar based component. To make the skin color detection
robust under varying illumination conditions, it is supplied with an automatic
white balance algorithm. The hypothesis of the user's position is used to
orient the robot's head towards the current user allowing it to grab high
resolution images of his face suitable for verifying the hypothesis and for
extracting additional information.

Summary: The development of a hybrid system for (mainly) gesture-based human-robot
interaction is presented, thereby describing the progress in comparison to the
work shown at the last gesture workshop (see [2]). The system makes use of
standard image processing techniques as well as of neural information
processing. The performance of our architecture includes the detection of a
person as a potential user in an indoor environment, followed by the
recognition of her gestural instructions. In this paper, we concentrate on two
major mechanisms: (i), the contour-based person localization via a combination
of steerable filters and three-dimensional dynamic neural fields, and (ii), our
first experiences concerning the recognition of different instructional
postures via a combination of statistical moments and neural classifiers.

Summary: We present a neural architecture for gesture-based interaction between a
mobile robot and human users. One crucial problem for natural interface
techniques is the robustness under highly varying environmental conditions.
Therefore, we propose a multiple cue approach for the localisation of a
potential user in the operation field, followed by the acquisition and
interpretation of its gestural instructions. The whole approach is motivated in
the context of a reliable operation scenario, but can be extended easily for
other applications, such as videoconferencing.
