(2018) : Self-integrating Organic Control Systems: from Crayfish to Smart Homes In: ARCS: ARCS Workshop 2018; 31th International Conference on Architecture of Computing Systems: Berlin, Germany: Axel Springer SE, S. 1-8.

Abstract: Survival in complex environments, for both natural and artificial systems, requires behavioural adaptation to common changes and behavioural innovation to face the unexpected. The challenge here is to produce a vast variety of behaviours, each adapted to current circumstances, while relying on a limited amount of resources (e.g. sensors, controllers and actuators), within a 'suitable' time-frame. Drawing inspiration from neural and behavioural studies on crayfish, this position paper brings to the fore several key design features that enable organisms to address this challenge. It then proposes a similar design for artificial controllers, based on: i) an extensible set of reusable control units; and, ii) a goal-driven, context-sensitive (self-)integration process for assembling control units into a wide variety of integrated system controllers. Pre-integrated sub-controllers can also be merged, to improve efficiency while avoiding conflicts. The proposal is illustrated via a proof-of-concept implementation for the smart home, where users can add and remove goals and devices at runtime and the controller is adapted accordingly. This study brings us closer to our long-term objective of defining reusable methodologies and platforms for the development of self-* systems running in complex unpredictable environments, notably including smart homes, cities, vehicular networks and electrical grids, merged via the Internet of Things, and of People.

(2018) : Real-time Intelligent Tele-Care Assistance Systems In: Institute of Electrical and Electronics Engineers: Broadband Coverage in Germany; 12th ITG-Symposium: Berlin, Germany: VDE Verlag GmbH, S. 1-4. Online verfügbar unter https://ieeexplore.ieee.org/document/8385230/
Abstract: The combination and fusion of technologies and procedures from "Ambient Assisted Living" (AAL), "Human-Technology Interaction" (MTI) and "eHealth" to target a real-time capable sensor data analysis-framework is the re-search focus of the "fast care"-project. This project is a part of the combined "fast" consortium at the Technical University of Dresden, which consists of more than 25 project parts working on the Next Generation 5G haptic internet. "Fast care" is focused on haptic care in the home environment. Measurements and observations by an adhoc-networked, real-time sensor infrastructure are performed with the aim of creating an integrated situation picture for direct interaction with an actor infrastructure or for the generation of a future forecast - with a latency period of less than 10 ms.

(2016) : Context-aware Planning by Refinement for Personal Robots in Smart Homes In: VDE: Proceedings of ISR 2016: 47st International Symposium on Robotics: Berlin: VDE Verlag GmbH. Online verfügbar unter https://ieeexplore.ieee.org/document/7559161/authors
Abstract: The idea of integrating robots and smart environments is becoming more popular. An important challenge for robotics and large advanced applications, such as Ambient Assisted Living, is to enable robots to seamlessly operate as part of smart spaces.They evolve in an unpredictable and highly dynamic environment where context information change quickly and where smart devices can join or leave it at anytime. In this situation, context-aware task planning is a key enabler. Actually, as the environment evolves, plans can become outdated, putting robots in blocking situations. Currently, few planners are able to consider smart spaces constraints during execution phase. In this paper, we propose a novel planning approach called DHTN (Dynamic HTN) based on HTN (Hierarchical Task Networks) planner. DHTN is able to generate and adapt the plan at execution and has the capability to smartly probe the environment by exclusively querying devices that provide useful data. Our approach was implemented and evaluated through simulation and a real life scenario using Nao robot in a smart office.

(2016) : What Older Adults would Like a robot to Do in Their Homes - First results from a User Study in the Homes of Users In: VDE: Proceedings of ISR 2016: 47st International Symposium on Robotics: Berlin: VDE Verlag GmbH. Online verfügbar unter https://ieeexplore.ieee.org/document/7559131/
Abstract: The paper presents a first analysis of user trials where for the first time a service robot was set free in the home of users. Users were provided with basic robot functionalities such as navigation, grasping objects from the floor, a series of entertainment functions such as listening to radio or books, a physical fitness application, and communication functions. Users could freely select what to do and have been questioned on what functionality would help them to stay longer at home and live independently.
