  @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{9974563, abstract = {Visual representations are used in various digitization processes to display objects in immersive environments. In industrial environments, the self-representation can be very helpful when reviewing 3D models to conform realistic proportions, particularly in combi-nation with haptic feedback that goes beyond vibrating controllers. For instance, haptic feedback in combination with a virtual representation supports working on use cases where collision is an important part to maintain data quality. To understand the dependency of both, we conducted a pilot study with 15 users from the automotive sector to examine the influence of upper limb representations on haptic feedback in Virtual Reality. Each participant was assigned with one of three upper limb representations which was used in different scenarios using haptic feedback devices. Overall, we found that the realistic arm representation was rated highest in terms of perceived realism and achieved the best task performance.}, author = {Hube, Natalie and Achberger, Alexander and Liepert, Philipp and Vogelsang, Jonas and Vidačković, Krešimir and Sedlmair, Michael}, booktitle = {2022 IEEE International Symposium on Mixed and Augmented Reality Adjunct (ISMAR-Adjunct)}, doi = {10.1109/ISMAR-Adjunct57072.2022.00172}, pages = {802-807}, title = {Study on the Influence of Upper Limb Representations and Haptic Feedback in Virtual Reality}, url = {https://ieeexplore.ieee.org/document/9974563}, 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 }
