In the Project "Semantic Product Memory" we exploit the lessons learned so far for the general design of a Digital Product Memory (DPM). DPMs can be used along their product's life cycle to collect data by different instances. In case of the individualized weekly medicament blister for patients from 7x4 Pharma not only the collected data but even the product itself is private. If we equip such a product with a DPM the collected data should be accessible -individually or role-based- only by authorized persons. This authorized access can be accomplished via a roles and rights management system and a secure identification provided by the new German electronic identity card. With our demonstrator we will present a system, which allows an authorized access on a DPM. Depending on the rights and roles of a user different data and different views will be available and displayed accordingly.

Adherence to therapy, what is termed "compliance", is a very important topic in Medicare. It has considerable effects not only in terms of enhancing quality of life for patients, but also in reducing the financial burden on the health care system. The individualized weekly medicament blister for patients (7x4 Box) from 7x4 Pharma increases the compliance and helps to keep the health expenditures as low as possible. A potential extension of the 7x4 Box could be a digital product memory which makes the imprinted data on the box electronically accessible in order to enable new innovative services which helps to increase the compliance. If we do not secure the data from an unauthorized access there is a possibility that third parties can read out the data unperceived and on a grand scale. In this paper we show how we can realize an authorized access -- individually or role-based -- on the data via identification by the new German electronic identity card.

This work describes a multimodal product information and comparison
system designed for a rural corner store (the so called Dorfladen). Such a
Dorfladen only provides a limited assortment, which we extend with virtual items
on embedded displays, allowing customers to inspect and select unavailable
products along their real world shopping activities for later ordering. We present
the design and implementation of the system prototype and discuss the main
results of a formal user study evaluating the user interface, which combines
tangible interaction and natural language dialogues to interact with real and virtual
products in one instrumented space.
Evaluating Tangible Interaction with Real and Virtual Products – Qualitative User Feedback Results

IADIS Interfaces and Human Computer Interaction (IHCI), Algarve, Portugal, 20 - 22 June
show abstract
In this paper, we introduce a user study of symmetric multimodal product information and comparison system related to tangible interaction with real and virtual products. The system aims to extend the limited assortment of a small store with virtual items on touch-sensitive display embedded into shelves. It blends tangible interaction of both real products in a shelf and virtual products represented on a nearby screen. The user interface is complemented with a conversational interface that allows users to carry out a natural language dialog to accomplish the comparison and inspection of multiple products of the real and virtual world. The user study examines whether the multimodal interaction with the prototype is perceived as intended. In particular, we describe the key issues of the qualitative user feedback and discuss their implications for the future research steps.
Burgomaster and Pedro - A Pervasive Multi-Player Game for Rural Tourism

show abstract
Pervasive Games have the potential to add new qualities to otherwise possibly tedious or uninspiring areas and let users interact with their environment in novel and enjoyable ways. The spreading of wireless communication infrastructures and low cost programmable mobile devices equipped with positioning systems and cameras span a large and growing open playground for pervasive gaming applications. In this work we describe the game Burgomaster and Pedro, the result of an interdisciplinary project for the state Ministry of Environment to promote development and tourism of rural areas. It is a multiplayer game that requires its players to explore villages in order to find real and virtual objects, which have to be delivered to given destinations. It also allows to hide from or seek other players, since objects that are being delivered can be stolen by competitors. GPS positioning, wireless communication and visual marker recognition are the key technologies in this game that is designed for playful engagement with rural environments.

LNCS, Springer-Verlag Berlin Heidelberg
show abstract
We present the Digital Sommelier, an interactive wine shopping assistant that provides an intuitive multi-modal interface to general product information as well as to particular attributes of a certain product, such as its current temperature. Wine bottles sense their state via attached wireless sensors and detect user interaction over RFID and acceleration sensors. Visitors can inquire information either through physical interaction with products or a natural language interface. We describe a framework and toolkit for efficient prototyping of sensor based applications as the foundation for the integration of different sensor networks utilized by the sommelier. We further introduce our concept of talking products, an anthropomorphic interaction pattern that allows customers to directly talk to products with personalities.

Big MaMUT is Watching You – Interaction-Tracking for Instrumented Environments
Michael Schmitz and Henning Zimmer
Proceedings of the 3rd IET International Conference on Intelligent Environments (IE’07), Ulm, Germany
[ DOWNLOAD NOTE ]
show abstract
A major challenge in ubiquitous computing applications
in intelligent environments is the simultaneous support
of multiple users, especially when users interact with
and move freely within the environment - without being
equipped with sensors or personal devices. In such a situation,
it is difficult to provide personalized services, which
- for example - rely on user profiles or histories, if the user
does not explicitly identify her- or himself with the system,
whenever an interaction takes place. We chose a computer
vision based approach to tackle this problem and divided
the problem space into two concerns: Macro-tracking takes
care of people tracking and consistent labelling of users in
order to determine which user is in vicinity of a specific
interactive device (e.g. a touchscreen); Micro-tracking observes
the adjacency of such an interactive device to resolve
ambiguities, in case that more than one person are potential
interactors. The results of these two trackers are fused to
conclude and assign persons to interactions, detected by the
environment. We describe our implementation that can theoretically
integrate arbitrary numbers of cameras, utilizing
off-the-shelf-hardware, i.e. personal computers and cameras
- which was one of the main requirements of MaMUT,
the Macro- and Micro User Tracker.

In this paper we report preliminary findings from two user studies
that on the one hand investigate how prosodic parameters of
synthetic speech can influence the perceived impression of the
speakers personality and on the other hand explores if and how
people attribute personality to objects such as typical products of
daily shopping. The results show that a) prosodic parameters have a
strong influence on the perceived personality and can be partially
used to achieve a desired impression and b) that subjects clearly
attribute personalities to products. Both findings encourage us to
continue our work on a dialogue shell for talking products.

Ubicomp research continually develops novel interaction techniques, sensing technologies, and new ways of presenting personalized information to the user. Gradually, companies operating in environments such as airports, museums or even shopping malls are becoming aware of the potential benefits in letting such technologies assist their users and customers. Intelligent environments are predicted to aid their users in pursuing their activities, such as wayfinding or shopping, through the situated presentation of personalized information. However, due to the large design space that ranges from wearable computing to public displays, the conceptual and technological choices pose new challenges to the designer of such user-assistance systems.
The MODIE workshop aims towards models, principles and methodologies, which guide the designer of an intelligent environment in the early stages of the development process, such as task and requirements analysis and conceptual design.

The emerging trend towards complex technology that supports multiple users in public spaces is evidenced by the presence of shared displays in shopping malls, museums, and airports. As sensing and interaction begin to play a greater role in these environments, application and interaction concepts are evolving to take the distribution and dynamics of users and devices into account. In this paper we describe a layered approach to support multiple in environments that allows concurrent interaction with multiple devices and displays. We further identify issues that arise in public, interactive spaces with multiple users and discuss how we address them in our proposed framework.

In this position paper we discuss the new interaction
paradigm of Anthropomorphized Objects, which involves
multimodal interaction with instrumented objects, spanning the
modalities of speech, gestures, sound and haptics. This work aims
at assisting non-expert users to access complex environments by
offering an intuitive interface to services that support users e.g. in
shopping malls to accomplish their shopping tasks. We further
argue that the notion of affect will not only enrich the user
experience but also has the potential to increase the efficiency of
interactions and problem solving abilities of the user.

Abstract. In this paper we describe a new way to improve the usability of complex hardware setups in Intelligent Environments. By introducing a virtual character, we facilitate intuitive interaction with our Intelligent Environment. The character is capable of freely moving along the wall of the room. The character is aware of the users position and orientation within the room. In this way, it may offer situated assistance as well as unambiguous references to physical objects by means of combined gestures, speech and physical locomotion. We make use of a steerable projector and a spatial audio system, in order to position the character within the environment.

We describe the design of an interactive beer mat for the support of entertainment activities in pubs. The mat uses a gravity sensor to sense motion and orientation in space and a pressure sensor to sense the weight resting on it. Care was also taken to preserve its original functions, such as absorbing superfluous liquids and providing advertising space. We present a number of activities supported by the mat and show how it can improve the profit of the pub and the mood of the crowd simultaneously.

Using Physiological Signals in a User-Adaptive Personal Assistant
Boris Brandherm, Holger Schultheis, Margeritta von Wilamowitz-Moellendorff, Tim Schwartz, Michael Schmitz
Proceedings of the 11th International Conference on Human-Computer Interaction (HCII-2005), Las Vegas, Nevada, USA, 2005
[BibTeX]
show abstract
Since psychophysiological signals are continuously available and usually quickly reflect changes of the user’s state, they constitute an important source of information for adaptive assistance systems. Despite their potential benefits however, physiological information is frequently neglected in current adaptive systems. This may—at least partly—be due to the fact that physiological measures cannot be easily used for adaptation. Instead several steps have to be taken to be able to draw on the advantages of physiology. First, each measure has to be evaluated regarding its suitability to distinguish between user states. Second, the exact relationships between physiological measures and states need to be identified. Finally, psychophysiological information has to be integrated over time and with other sources of information. In the scope of the BAIR project all three sub problems have been tackled and the respective solutions have been combined to give a systematic approach for the utilization of physiological information in user-adaptive personal assistance systems.

This paper presents an overview about ongoing work in the project REAL, where we have set up the Saarland University Pervasive Instrumented Environment (SUPIE). In particular we introduce the intelligent environment’s architecture, which serves as the basis for different services and applications running in the environment and supporting their users in different tasks. On the basis of this information we outline our user and location-modeling component needed to establish the navigational– and shopping-assistants developed so far. Both assistants support their users with especially customized presentations. These presentations will be automatically scheduled and presented on public displays in the environment, as explained in the remarks about the presentation manager. Finally, we provide a short outlook on planned future work in the project.

show abstract
In a student project over the summer of 2004 teams of computer science and product design students worked together to develop new forms of interfaces for media control in living room contexts. In this paper we des-cribe the design process from collecting first ideas of design choices and iteratively evolving (low-fidelity) prototypes to fully functional products, partially even meeting mass production requirements. We discuss how the interdisciplinary collaboration influenced the creative process in such a way, that the solutions were more realistic than purely design-informed solutions and more inspired than purely technology-informed ones. We experienced that the combination of skills lead to a much more focused design process, which produced fully functional prototypes in a short time. The resulting designs include one interface installed in the room, two autonomous interaction objects which can be freely moved around, and a two-handed inter-face. While these are only small spotlights into a large design space, they nicely show the possible diversity. We also learned that fully functional and aesthetically pleasing prototypes can be developed with techno-logically relatively simple means.
Managing Presentations in an Intelligent Environment
Christoph Stahl, Michael Schmitz, Antonio Krüger, Jörg Baus
MU3I Workshop at IUI 2005, San Diego, USA.
[pdf]
show abstract
Intelligent environments enable users to receive information
from a variety of sources, i.e. from a range of displays
embedded in those environments. From a services
perspective delivering presentations to users in such an
environment is not a trivial task. While designing a service
it is, for example, not clear at all which displays will be
present in the specific presentation situation and which of
those displays might be locked by other services. It is
further unclear if other users are able to see the
presentation, which could cause problems for the presentation
of private information in a public space. In this paper
we propose a solution to this problem by introducing the
concept of a presentation service that provides an
abstraction of the available displays. The service is able to
detect conflicts that arise when several users and services
try to access the same display space and provide strategies
to solve these conflicts by distributing presentations in
space and time. The service also notifies the user by a alarm
signal on a personal device each time a presentation is
shown on a public display in order to disambiguate content
between multiple users.

situated assistance to users within the environment. We make
use of a steerable projector and a spatial audio system, in
order to position the character within the environment. Our
concept of a virtual character “living” within the IE, and thus
playing the role of an assistant, allows both novice and advanced
users to efficiently interact with the different devices
integrated within the IE. The character is capable of welcoming
a first time visitor and its main purpose is to explain the
setup of the environment and to help users while interacting
with it.
