  • Designing EMS Control Loops using Reinforcement Learning and Neural Networks

    Electrical Muscle Stimulation (EMS) is being researched in many different applications in the field of human-computer interaction. Current limitations of using EMS refer to an only rough control of the muscles and the need for an individual calibration for each subject. The combination of Reinforcement Learning with Neural Networks showed in a previous thesis promising results to overcome these limitations.

    Die elektrische Muskelstimulation (EMS) wird für viele verschiedene Anwendungen im Bereich der Mensch-Computer-Interaktion erforscht. Aktuelle Einschränkungen bei der Verwendung von EMS beziehen sich auf eine nur grobe Steuerung der Muskeln und die Notwendigkeit einer individuellen Kalibrierung für jeden Probanden. Die Kombination von Reinforcement Learning mit Neuronalen Netzen zeigte in einer früheren Arbeit vielversprechende Ergebnisse bei der Überwindung dieser Einschränkungen.

  • Design and Implementation of a One-Handed Smartwatch Interaction for fast Responses via EMG

    Smartwatches use a small touch display to convey information to the user, e.g. notifications. To interact with a smartwatch mostly the touch screen is used. Other works focus on enhancing the interaction by gesture input based on the integrated acceleration sensor or adding other input sensors to the smartwatch as, e.g. a microphone, camera, distance sensors, etc. In this thesis the focus is on using an existing EMG wristband prototyp to recognize hand gestures and using these gestures to enable an same side one-handed interaction with the smartwatch for fast responses.

    The thesis should first focus on situations and task, in which a short reaction with less information is sufficient. E.g. getting a notification for a meeting an just acknowleding it by a meaningful gesture. A concept and a mapping of gesture to reaction should be created. One application scenario should be evaluated with the EMG based interaction in a user study to may answer the following questions:

    • Is the created mapping meaningful/natural?
    • Is the interaction less straining or faster than the interaction via the other hand on the touch display?


    For that purpose an Android Smartwatch application has to be created for the smartwatch and a Smartphone. Recording and classifying EMG hand gestures with machine learning methods are also part of this thesis.

  • Design and Evaluation of Haptic Mouse Feedback for One-Dimensional Input using EMS

    This thesis should investigate the opportunities of using electrical muscle stimulation (EMS) for providing haptic feedback for desktop mouse interactions. EMS ist able to provide strong haptic feedback in mobile contexts. We want to investigate the usage in a desktop environment. Possible application scenarios for providing haptic feedback in an desktop environment could be, e.g. supporting of snapping, using the haptic channel when navigating with the mouse over the desktop, e.g. augmenting window borders, so that a user can feel them when he travels from window to another or gaming applications. The feedback is limited to one dimensional feedback in this thesis to reduce the complexity. The thesis should find application scenarios that benefit from the haptic mouse feedback and should also evaluate one scenarion in a user study.

  • A Critical Look at Sustainability in HCI

    Bachelor Thesis, Student: Huong Nguyen, Supervisor: Jan Wolff, Start: June 2021

    Publications in HCI's subfield Sustainable HCI strive to present systems with a positive ecological impact. Common themes have included persuasive technology and ambient awareness as means to foster changes in personal behavior. However, as effects are yet to be widespread enough to positively influence global emissions and resource usage, other works criticized such approaches and ascribe a different role to HCI, in which more focus should be placed on the supply aspect of devices. Recent works also called for an application of the principles behind permaculture, in which waste is essentially avoided in favor of a circular resource usage. A more extreme lens is provided by Bill Tomlinson et al. with the notion of Collapse Informatics, in which a deliberately negative speculative future is used as a framing device for sustainability efforts of HCI and ICT in general. By imposing an assumption of extreme limits on resource availability, taking the complete supply chain into account automatically becomes a necessity when assessing designs of digital systems.

    In this thesis, the aim is to provide a comprehensive framework to help evaluate all facets of sustainability focused projects, in which their complete supply chain and lifecycle is taken into account. With this framing, a critical look at a representative subset of existing literature in the area of SHCI is to be provided. Furthermore, the framing is to be used as a tool to evaluate the viability of 2 to 3 existing and influential HCI/ICT projects. Their shortcomings are to be identified and speculative designs that help fit these projects into the developed framework are to be given. This, in turn, serves to identify user-visible aspects of such developments and is to provide a baseline for future work in which user concerns of such systems are addressed.

  • Augmentation of Headphones by Wearable Displays -- Design and Usage Scenarios

    Bachelor Thesis, Student: Pia Brandt, Supervisor: Dennis Stanke , Start: April 2021  

    Headphones allow defining your own soundscape and privately listening to audio sources in public. Active noise-cancelling headphones can even reduce external sounds that intrude into this soundscape. However, to others, the state of a person wearing headphones is unclear (is s/he listening to music? may s/he be spoken to?), which is socially problematic. The goal of this thesis is to explore whether displays integrated in headphones may help to communicate the state of the user to other people. What should be depicted on the display to indicate the state? What about privacy concerns? How should the headphones sense the state of the user? How could the user explicitly provide the content to be shown? This thesis comprises brainstorming about scenarios, sketching and designing potential visualizations on earpieces, asking potential users about the prospect of such display-enhanced headphones, and (if done as a Master's thesis) implementing a prototype. 

    Mit Kopfhörern können Sie Ihre eigene Klanglandschaft schaffen und Klangquellen in der Öffentlichkeit privat anhören. Kopfhörer mit aktiver Geräuschunterdrückung können sogar externe Geräusche, die in diese Geräuschkulisse eindringen, reduzieren. Für andere ist der Zustand einer Person, die Kopfhörer trägt, jedoch unklar (hört sie Musik? darf sie angesprochen werden?), was gesellschaftlich problematisch ist. Das Ziel dieser Arbeit ist es, zu untersuchen, ob in Kopfhörer integrierte Displays helfen können, den Zustand des Benutzers anderen Personen mitzuteilen. Was sollte auf dem Display abgebildet werden, um den Zustand anzuzeigen? Wie steht es um die Privatsphäre? Wie sollte der Kopfhörer den Zustand des Benutzers erkennen? Wie könnte der Benutzer den anzuzeigenden Inhalt explizit vorgeben? Diese Arbeit umfasst das Brainstorming über Szenarien, das Skizzieren und Entwerfen möglicher Visualisierungen auf den Kopfhörern, das Befragen potenzieller Benutzer über die Aussicht auf solche displaygestützten Kopfhörer und (falls als Masterarbeit durchgeführt) die Implementierung eines Prototyps.

  • An Interface for Interactive Exploration of Communities on Social Media

    Bachelor Thesis, Student: Maximilian Spiekermann, Supervisor: Jan Wolff , Start: April 2021

    The role social platforms play when it comes to radicalization on the internet is a hot topic. Increasingly segregated sub-communities ("filter bubbles") serve to reinforce fringe opinions and don't allow for healthy exposure to sentiments expressed elsewhere. Existing work has already been done to identify such bubbles within the social graph of Twitter. The goal of this thesis is to design an interface that enables an interactive exploration of this graph, with a focus on social bubbles and their interconnections. This includes researching methods to map and present the data and to consider which additional information could be displayed. Furthermore, a user study will have to be conducted to evaluate the design's expressiveness and intelligibility.

    Die Rolle, die soziale Plattformen bei der Radikalisierung im Internet einnehmen, ist ein brisantes Thema. Zunehmend abgetrennte Untergemeinschaften ("Filterblasen") führen zu einer Verstärkung von Randmeinungen und lassen keine gesunde Auseinandersetzung mit anderswo geäußerten Meinungen zu. Es gibt bereits Arbeiten, die solche Blasen innerhalb des sozialen Netzwerks von Twitter identifizieren. Das Ziel dieser Arbeit ist es, eine Schnittstelle zu entwerfen, die eine interaktive Erkundung dieses Graphen ermöglicht, mit einem Fokus auf soziale Blasen und deren Verbindungen untereinander. Dazu gehört die Erforschung von Methoden zur Abbildung und Darstellung der Daten und die Überlegung, welche zusätzlichen Informationen angezeigt werden könnten. Außerdem muss eine Benutzerstudie durchgeführt werden, um die Aussagekraft und Verständlichkeit des Designs zu evaluieren.

  • Preventing Selective Exposure on Twitter via Nudging

    Bachelor Thesis, Student: Kerim Balci, Supervisor: Jan Wolff , Start: April 2021

    The content provided to users of social platforms is pre-filtered based on past behaviour on the platform. It is subject to selection biases of individual users, thus preventing any confrontation with divergent opinions. This thesis concerns with the design of an interface that makes users aware of overly selective exposure in their social feeds. The aim of this interface is to subtly steer users towards a broader exposure via nudging. Said design nudge should incentivize users to counteract increasing disconnection of sub-communities on social platforms. Furthermore, a user study is to provide insight into the acceptance of such a feature and the agreement with its feedback.



  • Design and Evaluation of a Trackball as an Input Device for Smartwatches

    Bachelor Thesis, Student: Peer Schroth, Supervisor: Dennis Stanke , Start: April 2021

    The fact that the finger covers the screen during touch input and the user can no longer see the screen content is still a problem when using smartwatches. Many smartwatches have alternative input possibilities to the touchscreen to prevent this problem. These include the rotation of the crown or bezel to interact without covering the screen with the users finger. This thesis will analyze already implemented interaction techniques and extend them by using a trackball as input device. Therefore, a trackball crown should be created for an Android smartwatch. Focus of this thesis is also the evaluation of a trackball as input device for smartwatches and the analysis of the user acceptance in user studies.

  • Comparison and Evaluation of Public and Private Output Modalities on the Earlobe

    This thesis should investigate the earlobe as a location to provide feedback to a user, e.g. when a notification arrives. Designing different earclip prototypes to provide different feedback modalities is a part of the thesis as well as the evaluation if the provided feedback is suitable for earclips. As an additional feedback technology besides standard technologies, like e.g. vibration, electrotactile feedback should be presented on the earlobe. A user study should evaluate the feedback methods in direct comparison and should analyze the acceptance of the user. Further usage scenarios or application demos have to be developed and evaluated. The thesis should try to answer the following questions: Which criteria are important for users if feedback ist presented at the earlobe? Which feedback technology do user prefer? Is there a significant difference in reaction time in a distraction task?

  • Design and Evaluation of a Wrist-Band Prototype for Hand Gesture Recognition via Electromyography

    This thesis is about the evaluation and the refinement of a prototype for the measurement of EMG signals on the forearm. The prototype differs from commercially available devices like the MYO armband in the fact, that it has only one EMG sensor instead of eight sensors but also eight electrode pairs. This setup brings therefore some limitations, e.g. measuring all eight electrodes with one sensor needs 40ms resulting in a frequency of 20Hz. The question is, if these limitations result in a lower recognition accuracy of gestures. By further improving the prototype, it should be able to use 16 electrode pairs. The amount of needed EMG sensors for the future prototype should be evaluated in this work to guarantee a good hand gesture recognition.
