Since such "digital product memories" may contain a vast amount of heterogeneous data, we expect a strong demand for user support in tasks related to information retrieval and discovery. In this article, we focus on the interaction between consumers and digital product memories in a retail scenario. On the basis of several prototype implementations, we summarize various ways of retrieving and presenting product-related information with the goal to shed some light upon aspects of relevance for the interaction between users and object memories in general.

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 presen- tation 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.

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.

The system adapts to almost arbitrary loudspeaker configurations, which affords a high flexibility for the deployment of the audio system regarding amount and placement of speakers. 3D sounds can be created and easily spatialized in real-time by providing the sound (e.g. as a file) and its virtual position in space.

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.

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

By introducing a virtual character, we facilitate intuitive interaction with our Intelligent Environment. The character is capable of freely moving along the walls 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.
