	abstract = {Haptics are an important factor to make virtual worlds and remote interpersonal interaction tangible. While current technological advances, such as Virtual Reality (VR), are reaching the mass market, they are primarily visual while available haptic devices are mostly limited to vibrotactile stimuli, such as smartphone notifications or embedded in game controllers. However, haptic feedback consists of more components that make an experience physically perceivable and lifelike. In addition to the vibrotactile stimulation of fine mechanoreception, these also incorporate stronger forces addressing pressure-based mechanoreception, temperature perceived by thermoception, and body position and movement perceived by proprioception, which are all parts of the somatosensory system. Consequently, to get closer to a full haptic experience, haptics need to be considered in the broader context of the complete somatosensory system.  In this thesis, novel haptic concepts will be introduced and implemented in prototypical systems to investigate them in a series of user studies, leading to a better understanding of somatosensory interaction. In this context, this dissertation provides six major contributions: (1) The first contribution presents a systematic investigation of fine and subtle mechanoreception involving vibrotactile stimuli on the hand for guidance and target acquisition. (2) The second contribution investigates more intense and pressure-based mechanoreception that employs pneumatically actuated air cushions to create immediate pressure sensations. (3) The third contribution on mechanoreception combines the findings of the previous two contributions and explores moving touches and stroke stimuli on the body, as well as their roughness perception in VR. (4) The fourth contribution addresses thermoception where the effects of cold and warm temperatures on the body are investigated within a VR environment. (5) The fifth contribution focuses on proprioception and kinesthesia and examines concepts for kinesthetic actuations that can evoke flexion and extension of body joints. (6) In a further contribution, a novel rapid prototyping platform is presented that considers the specific requirements for haptic actuations of the somatosensory system.},

	abstract = {Haptic Feedback is essential for lifelike Virtual Reality (VR) experiences. To provide a wide range of matching sensations of being touched or stroked, current approaches typically need large numbers of different physical textures. However, even advanced devices can only accommodate a limited number of textures to remain wearable. Therefore, a better understanding is necessary of how expectations elicited by different visualizations affect haptic perception, to achieve a balance between physical constraints and great variety of matching physical textures. In this work, we conducted an experiment (N=31) assessing how the perception of roughness is affected within VR. We designed a prototype for arm stroking and compared the effects of different visualizations on the perception of physical textures with distinct roughnesses. Additionally, we used the visualizations' real-world materials, no-haptics and vibrotactile feedback as baselines. As one result, we found that two levels of roughness can be sufficient to convey a realistic illusion.},

Since smartphones and AR glasses are the primary devices to present AR information to users, it is essential to understand how the information about a historical site can be presented effectively and what type of device is best suited for information placements. In this paper, we investigate the placement of two types of content, historical images and informational text, for smartphones and AR glasses in the context of outdoor historical sites. For this, we explore three types of placements: (1) on-body, (2) world, and (3) overlay. To evaluate all nine combinations of text and image placements for smartphone and AR glasses, we conducted a controlled experiment (N = 18) at outdoor historical landmarks. We discovered that on-body image and text placements were the most convenient compared to overlay and world for both devices. Furthermore, participants found themselves more successful in exploring historical sites using a smartphone than AR glasses. Although interaction with a smartphone was more convenient, participants found exploring AR content using AR glasses more fun.},

According to accident reports, one of the most dangerous situations for cyclists are uncontrolled intersections, where cars approach from both directions. To address this issue and assist cyclists in crossing decision-making at uncontrolled intersections, we designed two visualizations that: (1) highlight occluded cars through an X-ray vision and (2) depict the remaining time the intersection is safe to cross via a Countdown. To investigate the efficiency of these visualizations, we proposed an Augmented Reality simulation as a novel evaluation method, in which the above visualizations are represented as AR, and conducted a controlled experiment with 24 participants indoors. We found that the X-ray ensures a fast selection of shorter gaps between cars, while the Countdown facilitates a feeling of safety and provides a better intersection overview.},

However, there is still a lack of systematic understanding of how the accuracy and efciency of such grips are afected by various factors such as counterforce, grip span, and grip direction. Therefore, in this paper, we contribute an evaluation (N = 18) of thumb-index pinching performance in a visual targeting task using scales up to 75 items. As part of our fndings, we conclude that the pinching interaction between the thumb and index fnger is a promising modality also for one-dimensional input on higher scales. Furthermore, we discuss and outline implications for future user interfaces that beneft from pinching as an additional and complementary interaction modality.},

	abstract = {Computer-supported posture guidance is used in sports, dance training, expression of art with movements, and learning gestures for interaction. At present, the influence of display types and visualizations have not been investigated in the literature. These factors are important as they directly impact perception and cognitive load, and hence influence the performance of participants. In this paper, we conducted a controlled experiment with 20 participants to compare the use of five display types with different screen sizes: smartphones, tablets, desktop monitors, TVs, and large displays. On each device, we compared three common visualizations for posture guidance: skeletons, silhouettes, and 3d body models. To conduct our assessment, we developed a mobile and cross-platform system that only requires a single camera. Our results show that compared to a smartphone display, larger displays show a lower error. Regarding the choice of visualization, participants rated 3D body models as significantly more usable in comparison to a skeleton visualization.},

However, prototyping of actuated devices nowadays often requires repetitive and time-consuming steps, such as wiring, soldering, and programming basic communication, before HCI researchers and designers can focus on their primary interest: designing interaction. In this paper, we present ActuBoard, a prototyping platform to support 1) quick assembly, 2) less preparation work, and 3) the inclusion of non-tech-savvy users. With ActuBoard, users are not required to create complex circuitry, write a single line of firmware, or implementing communication protocols. Acknowledging existing systems, our platform combines the flexibility of low-level microcontrollers and ease-of-use of abstracted tinker platforms to control actuators from separate applications. As further contribution, we highlight the technical specifications and published the ActuBoard platform as Open Source.},

In this paper, we propose Therminator, a thermal display concept that provides warm and cold on-body feedback in VR through heat conduction of flowing liquids with different temperatures. Further, we systematically evaluate the interdependency of different visual and thermal stimuli on the temperature perception of arm and abdomen with 25 participants.

Yet, group discussions, especially in a business context, are still challenging as non-verbal communication (NVC) is often depicted on digital whiteboards, including deictic gestures paired with visual artifacts. However, as NVC heavily relies on the visual perception, whichrepresents a large amount of detail, an adaptive approach is required that identifies the most relevant information for BVIP. Additionally, visual artifacts usually rely on spatial properties such as position, orientation, and dimensions to convey essential information such as hierarchy, cohesion, and importance that is often not accessible to the BVIP. In this paper, we investigate the requirements of BVIP during brainstorming sessions and, based on our findings, provide an accessible multimodal tool that uses non-verbal and spatial cues as an additional layer of information. Further, we contribute by presenting a set of input and output modalities that encode and decode information with respect to the individual demands of BVIP and the requirements of different use cases.",

	abstract = {Recent technological advances have made head-mounted displays (HMDs) smaller and untethered, fostering the vision of ubiquitous interaction in a digitally augmented physical world. Consequently, a major part of the interaction with such devices will happen on the go, calling for interaction techniques that allow users to interact while walking. In this paper, we explore lateral shifts of the walking path as a hands-free input modality. The available input options are visualized as lanes on the ground parallel to the user's walking path. Users can select options by shifting the walking path sideways to the respective lane. We contribute the results of a controlled experiment with 18 participants, confirming the viability of our approach for fast, accurate, and joyful interactions. Further, based on the findings of the controlled experiment, we present three example applications.}

	abstract="This paper presents a brainstorming tool combined with pointing gestures to improve the brainstorming meeting experience for blind and visually impaired people (BVIP). In brainstorming meetings, BVIPs are not able to participate in the conversation as well as sighted users because of the unavailability of supporting tools for understanding the explicit and implicit meaning of the non-verbal communication (NVC). Therefore, the proposed system assists BVIP in interpreting pointing gestures which play an important role in non-verbal communication. Our system will help BVIP to access the contents of a Metaplan card, a team member in the brainstorming meeting is referring to by pointing. The prototype of our system shows that targets on the screen a user is pointing at can be detected with 80{\%} accuracy.",

	abstract={Virtual Reality Environments (VRE) create an immersive user experience through visual, aural, and haptic sensations. However, the latter is often limited to vibrotactile sensations that are not able to actively provide kinesthetic motion actuation. Further, such sensations do not cover natural representations of physical forces, for example, when lifting a weight. We present PneumAct, a jacket to enable pneumatically actuated kinesthetic movements of arm joints in VRE. It integrates two types of actuators inflated through compressed air: a Contraction Actuator and an Extension Actuator. We evaluate our PneumAct jacket through two user studies with a total of 32 participants: First, we perform a technical evaluation measuring the contraction and extension angles of different inflation patterns and inflation durations. Second, we evaluate PneumAct in three VRE scenarios comparing our system to traditional controller-based vibrotactile and a baseline without haptic feedback.}

abstract="Although many security solutions exist, home computer systems are vulnerable against different type of attacks. The main reason is that users are either not motivated to use these solutions or not able to correctly use them. In order to make security software more usable and hence computers more secure, we re-ran the study by Wash about ``Folk Models of Home Computer Security'' in Germany. We classified the different mental models in eleven folk models. Eight of the identified folk models are similar to the models Wash presented. We describe each folk model and illustrate how users think about computer security.",
