“…Video-see-through AR allows a more detailed manipulation of the reality display and, thus, a better integration of the virtual content. The problem here is often latency and quality degradation in the image display, which hinders usage of the visualization and leads to cyber-sickness [ 31 ]. While these factors preclude actual clinical use of many video see-through devices, it still results in an opportunity to explore AR, regardless of the limitations associated with using optical see-through displays.…”

AR-Supported Supervision of Conditional Autonomous Robots: Considerations for Pedicle Screw Placement in the Future

et al. 2022

Robotic assistance is applied in orthopedic interventions for pedicle screw placement (PSP). While current robots do not act autonomously, they are expected to have higher autonomy under surgeon supervision in the mid-term. Augmented reality (AR) is promising to support this supervision and to enable human–robot interaction (HRI). To outline a futuristic scenario for robotic PSP, the current workflow was analyzed through literature review and expert discussion. Based on this, a hypothetical workflow of the intervention was developed, which additionally contains the analysis of the necessary information exchange between human and robot. A video see-through AR prototype was designed and implemented. A robotic arm with an orthopedic drill mock-up simulated the robotic assistance. The AR prototype included a user interface to enable HRI. The interface provides data to facilitate understanding of the robot’s ”intentions”, e.g., patient-specific CT images, the current workflow phase, or the next planned robot motion. Two-dimensional and three-dimensional visualization illustrated patient-specific medical data and the drilling process. The findings of this work contribute a valuable approach in terms of addressing future clinical needs and highlighting the importance of AR support for HRI.

“…the number of ideas generated during the limited time of the experiment. The discomfort felt by users in VR varies according to the characteristics of the hardware (Freiwald, Katzakis & Steinicke, 2018), the software (Jung, Cho, Choi & Choi, 2017;Porcino, Trevisan & Clua, 2019), the type of task (Park, Choi, Kim & Kim, 2005), but also the individual (Risi & Palmisano, 2019). It is therefore important in the design of ideation tools to follow good practices to design technologies that will minimize cybersickness (Porcino et al, 2017;Choroś & Nippe, 2019) and thus maximize the number of ideas generated by users.…”

CRUX: a creativity and user experience model

et al. 2021

The field of Virtual Reality has been developing at a steady pace, and VR is finding new uses as a support for creative tasks. The objective of this study is to propose a theoretical model describing the links between user experience and creativity. Pre-existing theoretical links have been identified in relevant scientific literature. Two experiments were then conducted in order to identify new links and replicate results. These experiments involved respectively 76 and 42 participants who individually performed a task requiring divergent creativity using virtual reality drawing tools. The results indicate that cybersickness leads to a decrease in fluency, i.e. the number of ideas generated, but also shades the links between flow and the relevance of the ideas generated. On the basis of this result, we propose the CRUX model to lead to recommendations for the design of tools and simulations to support divergent creativity.

“…It would therefore appear that stabilizing image content at different simulated depths might be critical for minimising cybersickness and its severity. Fortunately, there are also exciting approaches being implemented in augmented and mixed reality for optimizing fidelity in display alignment to minimize perceptual incompatibility when mixing virtual content with real-world visual information (Yokokohji et al, 2000;Freiwald et al, 2018).…”

Effects of display lag on vection and presence in the Oculus Rift HMD

et al. 2021

We used the Oculus Rift head-mounted display (consumer release -CV1) to simulate forward self-motion in depth. Observers made continuous yaw head movements at approximately 0.5 Hz or 1.0 Hz while viewing these selfmotion simulations. We examined the perceptual effects of increasing the head-to-display lag, by adding lag to the baseline lag of the system (estimated to be approximately 5.3 ms). We found that increasing the head-to-display lag up to 212 ms reduced the presence and the strength of the illusory self-motion (vection). In addition, faster (1.0 Hz) head oscillations were found to generate weaker presence and vection than the slower (0.5 Hz) head oscillations. Both vection and presence in virtual environments can therefore be impaired by either increasing head-display lag or making more rapid angular head movements.
