Immersive output and natural input are two core aspects of a virtual reality experience. Current systems are frequently operated by a controller or gesture-based approach. However, these techniques are either very accurate but require an effort to learn, or very natural but miss haptic feedback for optimal precision. We transfer ubiquitous touch interaction with haptic feedback into a virtual environment. To validate the performance of our implementation, we performed a user study with 28 participants. As the results show, the movable and cheap real world object supplies an accurate touch detection that is equal to a laserpointer-based interaction with a controller. Moreover, the virtual tablet can extend the functionality of a real world tablet. Additional information can be displayed in mid-air around the touchable area and the tablet can be turned over to interact with both sides. Therefore, touch interaction in virtual environments allows easy to learn and precise system interaction and can even augment the established touch metaphor with new paradigms.

“…Moreover VR has been proven to be an important tool for simulating stressful and cognitively demanding scenarios in e.g. military trainings [3,5], pilot flight trainings [13,14], other dangerous working environments, such as petrol refinery [7]. Aiming to train soldiers, flight pilots, and also firefighters stress elicitation in VR has pointed towards an important research gap.…”

Virtual reality (VR) is used for different trainings e.g. for pilots, athletes, and surgeons. Dangerous and difficult situations are often focused in such simulations in VR, targeting to learn how to perform well under stress. However, there has been little work on understanding stress perception in VR compared to the real-world situation. In this paper we present an investigation of how users experience a stressful task in VR compared to in a classic office environment. Specifically, we investigate the subjective stress experience and physiological arousal with 15 participants performing the Stroop color word test either on a regular desktop screen, in VR, or in VR requiring head movements. Our findings suggest that stressful tasks are perceived less stressful when being performed in VR compared to the real environment as long as there is no additional stress factor, such as head movement involved. Our work indicates that it may be valuable to transfer stressful tasks, currently done in traditional office environments into VR.

“…In previous work [14,15] we investigated the impact of altered gravity on direct AR object selection for symbolic-input and control tasks. Therefore we performed two experiments under parabolic flight conditions to find out which interface alignment is the most efficient one and preserves human's hand-eye coordination under altered gravity.…”

Abstract. Direct object selection in an Augmented Reality environment that is coded outside of human body frame of reference is deteriorated under short-term altered gravity. As countermeasures we developed a gravity-adapted resizing technique based on the Hooke's law that resulted in two techniques of target and interface deformation (compression, elongation). To prove the concept of this resizing approach we initially conducted two experiments under simulated hypergravity conditions. While during the first study hypergravity was induced by a long-arm human centrifuge, in the second study hypergravity was simulated by additional arm weightings that were balanced and attached to the participants' pointing arm. We investigated the difference of the task performance with respect to the pointing frequency, response time, pointing speed and accuracy, when participants performed a visuomotor task under the resizing conditions compared to the unchanged condition. During the second study we additionally evaluated the speed-accuracy tradeoff of the resizing techniques according to Fitts' law and the physiological workload by cardiac responses analyzing the heart rate variability. Both experiments showed that the online adaption of the present gravity load to targets' size and distance influences the performance of direct AR direct pointing. The results revealed that the pointing performance benefits from elongation target deformation by increased target sizes and distances, while pointing towards compressed targets mostly decreases the physiological workload under increased gravity conditions.
