DFG-Projekt OffshorePlan

Shengrui Peng (L3S), Matthias Becker, Helena Szczerbicka (L3S)
Komplementäre Nutzung mathematischer und ereignisdiskreter Modelle zur Lösung komplexer Planungs- und Steuerungsprobleme in der Offshore-Baustellenlogistik (2019-2021). Projektpartner: BIBA - Bremer Institut für Produktion und Logistik


Multiwave is a fully configurable function generator for haptic feedback that can control a large number of outputs in all signal parameters completely independend from each other.

MuscleIO: Muscle-Based Input and Output for Casual Notifications

MuscleIO is an interaction technique that uses the users muscle as an input and output device. We present on our project page the concept and our prototype. Resources to rebuild the system can also be found on the project page.


Pentelligence is a digital pen that recognizes handwriting with audio and motion data. It uses deep learning to achieve recognition rates of over 98% on digits without any writing instructions.

DSSARTH: Entwicklung eines automatisierten Entscheidungshilfe Systems für den biologischen und integrierten Pflanzenschutz unter Glas

Ziel des Projekts ist die Entwicklung einer einfachen und benutzerfreundlichen Entscheidungshilfe für den biologischen und integrierten Pflanzenschutz von Schadarthropoden unter Glas. Zentrales Element ist die regelmäßige Erfassung der Populationsdichte im Bestand, die durch einen automatisierten Prozess vereinfacht werden soll.

Zap++ - An EMS System for Fine-Grained Wearable Force Feedback

Zap++ is an prototype stimulator for fine grained electrical muscle stimulation (EMS). It is designed to enable complex, mobile EMS Feedback.


HapticHead is a novel around-the-head tactile display which can be used as an output system for moving tactile 3D guidance cues or immersive applications in Virtual- and Augmented Reality.
