    Adaptive Architectures for Robust Data Management Systems
    (BTW 2023, 2023) Bang, Tiemo
    Form follows function is a well-known expression by the architect Sullivan asserting that the architecture of a building should follow its function. 'Adaptive Architectures for Robust Data Management Systems' is a dissertation asserting that DBMS architectures should follow changing workload and hardware to robustly achieve high DBMS performance. The dissertation first evaluates how workload and hardware affect the performance of DBMSs with static architectures. This evaluation concludes that static DBMS architectures degrade DBMS performance under changing workload and hardware, and hence the DBMS architecture has to become adaptive. Subsequently, adaptation concepts for the architecture of single-server and multi-server DBMSs are proposed. These concepts focus fine-grained adaptation of DBMS architectures and are realized through asynchronous programming models. These programming models decouple the implementation of DBMS components from fine-grained architectural optimization. Thereby, optimizers can derive novel architectures better fitting individual DBMS components, leading to high and robust DBMS performance under changing conditions.

    Co-constructing Grounded Symbols—Feedback and Incremental Adaptation in Human–Agent Dialogue
    (KI - Künstliche Intelligenz: Vol. 27, No. 2, 2013) Buschmeier, Hendrik; Kopp, Stefan
    Grounding in dialogue concerns the question of how the gap between the individual symbol systems of interlocutors can be bridged so that mutual understanding is possible. This problem is highly relevant to human–agent interaction where mis- or non-understanding is common. We argue that humans minimise this gap by collaboratively and iteratively creating a shared conceptualisation that serves as a basis for negotiating symbol meaning. We then present a computational model that enables an artificial conversational agent to estimate the user’s mental state (in terms of contact, perception, understanding, acceptance, agreement and based upon his or her feedback signals) and use this information to incrementally adapt its ongoing communicative actions to the user’s needs. These basic abilities are important to reduce friction in the iterative coordination process of co-constructing grounded symbols in dialogue.

    Search Engine for Children: User-Centered Design
    (Datenbank-Spektrum: Vol. 17, No. 1, 2017) Gossen, Tatiana; Kotzyba, Michael; Nürnberger, Andreas
    Children are a fast growing user group on the Internet. Among different online activities, children use web search engines in order to gather information related to their personal interests and school activities. Children’s knowledge, cognitive abilities and fine motor skills are different from those of adults. Therefore, they may experience difficulties with search engines that are built using standard information retrieval algorithms and search interfaces for adults. Special or targeted search engines for children are essential in order to better support children in their search tasks. However, the design of search solutions for children is not an easy task. Not only are children’s abilities different from the abilities of adults, children also undergo relatively fast changes in their abilities. In order to tackle this challenge, an age-adaptable information terminal for children with a special focus on the search user interface (SUI) has been developed in three stages following a user-centered design. Specifically, it addresses the changing characteristics of the users by providing a means of adaptation. Several user studies have been conducted with children during the development to ensure the usability of the information terminal.

    Unleashing the Power of Wearable Technology: Enhancing Health and Adaptation for International Students in Transition to Germany
    (Mensch und Computer 2023 - Workshopband, 2023) Pankhuri, Pankhuri; Aghamohammadian, Nasim; Osipova, Margarita
    International students encounter many challenges while relocating to a foreign country that impacts their mental and physical well-being, creating a cumbersome adaptation process within the new academic and cultural environment. We conducted a series of participatory design sessions with 20 participants from 10 countries to understand international students’ most pressing challenges during their transition to Germany and involve this population in the design process. We revealed the envisioned features of wearable technology as described by international students. Our findings indicate that the continuous accessibility characteristic of wearable technology can facilitate task management among students while also providing essential support for their well-being through monitoring physical and psychological parameters. Furthermore, integrating immersive technology with wearables emerged as a frequently requested addition, enhancing real-time connectivity and assisting students with navigation.
