With the technological advancements, these systems are becoming more adaptable to the users' needs and can better imitate a human personality. To achieve that efficiently, understanding how different users envision their desired assistant is crucial.

abstract = {Visitors in smart homes might want to use certain device features, as far as permitted by the device owner (e.g., streaming music on a smart speaker). At the same time, protecting access to features from attackers is crucial, motivating a need for authentication. However, it is unclear if and how smart home visitors should authenticate as they usually do not have access to respective interfaces. We explore considerations for the design of authentication for visitors evolving around, e.g., the visitors themselves as well as the environment and concrete mechanisms. Moreover, we suggest a concrete idea: security questions to authenticate visitors in smart homes.
In an interview study (N=24), we found that owners and visitors appreciated the low effort and would adapt our approach. We conclude with future research directions that we hope will spark further discussions around the design of authentication for smart homes, considering visitors and owners alike.},

In particular, the accident rates for E-Scooter riders increase, which endangers the riders and other road users. In this paper, we explore the idea of augmenting E-Scooters with unimodal warnings to prevent collisions with other road users, which include Augmented Reality (AR) notifications, vibrotactile feedback on the handlebar, and auditory signals in the AR glasses. We conducted an outdoor experiment (N = 13) using an Augmented Reality simulation and compared these types of warnings in terms of reaction time, accident rate, and feeling of safety. Our results indicate that AR and auditory warnings lead to shorter reaction times, have a better perception, and create a better feeling of safety than vibrotactile warnings. Moreover, auditory signals have a higher acceptance by the riders compared to the other two types of warnings.},

Building on these findings, we developed EyeMeet, an eye-based joint attention support system that combines state-of-the-art real-time joint attention support with a retrospective attention feedback for remote meetings. In a four-week study, two student groups worked remotely on course assignments using EyeMeet. Our findings of the study highlight that EyeMeets supports students in staying more focused on the meetings.

ONYX introduces an interactive task learning (ITL) based approach which enables NLIs to learn from users through natural interactions. Users can personalize the NLI with new commands using direct manipulation, known commands, or by combining both. To further support users during the training process, we derived two design goals for the user interface, namely providing suggestions based on sub-parts of the command and addressing ambiguities through follow-up questions and instantiated them in ONYX. In order to trigger reflections and gain feedback on possible design trade-offs of ONYX and the instantiated design goals, we performed a formative user study to understand how to successfully integrate the suggestions and follow-up question into the interaction.},

While natural language interfaces (NLIs) are increasingly utilized to simplify the interaction with data visualization tools, improving and adapting the NLIs to the individual needs of users still requires the support of developers. ONYX introduces an interactive task learning (ITL) based approach which enables NLIs to learn from users through natural interactions. Users can personalize the NLI with new commands using direct manipulation, known commands, or by combining both. To further support users during the training process, we derived two design goals for the user interface, namely providing suggestions based on sub-parts of the command and addressing ambiguities through follow-up questions and instantiated them in ONYX. In order to trigger reflections and gain feedback on possible design trade-offs of ONYX and the instantiated design goals, we performed a formative user study to understand how to successfully integrate the suggestions and follow-up question into the interaction.
