  @article{achberger2022touching, abstract = {Immersive analytics often takes place in virtual environments which promise the users immersion. To fulfill this promise, sensory feedback, such as haptics, is an important component, which is however not well supported yet. Existing haptic devices are often expensive, stationary, or occupy the user’s hand, preventing them from grasping objects or using a controller. We propose PropellerHand, an ungrounded hand-mounted haptic device with two rotatable propellers, that allows exerting forces on the hand without obstructing hand use. PropellerHand is able to simulate feedback such as weight and torque by generating thrust up to 11 N in 2-DOF and a torque of 1.87 Nm in 2-DOF. Its design builds on our experience from quantitative and qualitative experiments with different form factors and parts. We evaluated our prototype through a qualitative user study in various VR scenarios that required participants to manipulate virtual objects in different ways, while changing between torques and directional forces. Results show that PropellerHand improves users’ immersion in virtual reality. Additionally, we conducted a second user study in the field of immersive visualization to investigate the potential benefits of PropellerHand there.}, author = {Achberger, Alexander and Heyen, Frank and Vidackovic, Kresimir and Sedlmair, Michael}, doi = {10.1007/s12650-022-00859-2}, journal = {Journal of Visualization}, title = {Touching data with PropellerHand}, url = {https://doi.org/10.1007/s12650-022-00859-2}, year = 2022 }

  @inproceedings{achberger2021uist, abstract = {The large potential of force feedback devices for interacting in Virtual Reality (VR) has been illustrated in a plethora of research prototypes. Yet, these devices are still rarely used in practice and it remains an open challenge how to move this research into practice. To that end, we contribute a participatory design study on the use of haptic feedback devices in the automotive industry. Based on a 10-month observing process with 13 engineers, we developed STRIVE, a string-based haptic feedback device. In addition to the design of STRIVE, this process led to a set of requirements for introducing haptic devices into industrial settings, which center around a need for flexibility regarding forces, comfort, and mobility. We evaluated STRIVE with 16 engineers in five different day-to-day automotive VR use cases. The main results show an increased level of trust and perceived safety as well as further challenges towards moving haptics research into practice.}, author = {Achberger, Alexander and Aust, Fabian and Pohlandt, Daniel and Vidackovic, Kresimir and Sedlmair, Michael}, booktitle = {ACM Symposium on User Interface Software and Technology (UIST)}, doi = {10.1145/3472749.3474790}, pages = {841--853}, title = {{STRIVE}: String-Based Force Feedback for Automotive Engineering}, url = {https://doi.org/10.1145/3472749.3474790}, year = 2021 }

With the increas�ing amount of video data, traditional analysis approaches can no longer be conducted in an acceptable timeframe. To address this issue, we collaboratively developed Caarvida, a visual analytics tool that helps engineers to accomplish their tasks faster and handle an increased number of videos. Caarvida combines automatic video analysis with interactive and visual user interfaces.
