We aim to construct a perception-based shape display system to provide users with the sensation of touching virtual objects of varying shapes using only a simple mechanism. We have confirmed that the perception of each primitive shape such as curvature and angle could be modified by displacing a user's hand image on the monitor as if s/he were touching the visual shape while actually touching another shape. In this study, we constructed the method to merge these findings for displaying more various shapes, including angular ones. We built a transmutative device, which the user touches. The device does not undergo significant transformation, but its surface can be slightly bumped in and out, and displayed various shapes with various angles, length and curvature. The results of experimental trials confirmed that our method for displaying each primitive shape can also worked as designed when we combine these findings to display more complex objects using this device which transforms slightly.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Previous research on healthy users has investigated a VE's effects on presence, gait (i.e., walking patterns), and physiological responses (e.g., heart rate). However, almost all of the previous research studies have been conducted only with healthy persons. Thus, it very little is known about how MI persons respond to a VE physiologically, how a VE will affect their gait (i.e., walking patterns), or how their sense of presence may differ from healthy persons. To begin investigating this, we designed a VE that included a range of multimodal feedback to induce a strong sense of presence and was novel to the participants. Using this VE, we conducted a study with two different populations: 8 MI persons and 8 healthy persons. The healthy participants were of similar demographics (e.g., age, weight, height) to the MI participants. The MI population was symptomatically homogeneous (e.g., they all walked with canes) and no participants had cognitive impairment. This is one of the first studies to investigate how a VE can affect MI users' gait, physiological response, and presence.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Previous research has indicated that craving for food can be elicited by exposure to food cues [Ferriday and Brunstrom 2011; Sobik, Hutchinson and Craighead 2005]. Given that craving for food is considered a trigger of bingeing, cue-exposure therapy with response prevention of bingeing may be effective in extinguishing the craving response in patients with eating disorders and obesity. However, the application of the in vivo cue exposure technique in the therapist's office faces logistical difficulties and is hampered by a lack of ecological validity [Koskina, Campbell and Schmidt 2013]. The use of Virtual reality (VR) technology may overcome the difficulties described. Nevertheless, before VR-based cue-exposure can be used for therapeutic purposes, the ability of VR scenarios to elicit craving responses in participants must be assessed. This is the objective of the present study.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

This paper advocates a virtual-reality (VR) approach to minimally-invasive surgery/therapy (e.g., percutaneous coronary intervention) in medical procedures. In particular, we devise a robust and accurate physics-based modeling and simulation algorithm for the guidewire interaction with blood vessels. We also showcase a VR-based prototype system for simulating percutaneous coronary intervention and mimicing the intervention therapy, which affords the utility of flexible, slender guidewires to advance diagnostic or therapeutic catheters into a patient's vascular anatomy, supporting various real-world interaction tasks. The slender body of guidewires are modeled using the famous Cosserat theory of elastic rods. We derive the equations of motion for guidewires with continuous energies and integrate them with the implicit Euler solver, that guarantees robustness and stability. Our approach's originality is primarily founded upon its power, flexibility, and versatility when interacting with the surrounding environment, including novel strategies in the hybrid of geometry and physics, material variability, dynamic sampling, constraint handling and energy-driven physical responses. Our experimental results have shown that this prototype system is both stable and efficient with real-time performance. In the long run, our algorithm and system are expected to contribute to interactive VR-based procedure training and treatment planning.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

We propose a framework based on patterns to evaluate surgical performance and provide feedback during simulated ear (temporal bone) surgery in a 3D virtual environment. Temporal bone surgery is composed of a number of stages with distinct aims and surgical techniques. To provide context-appropriate feedback we must be able to identify each stage, recognise when feedback is to be provided, and determine the nature of that feedback. To achieve these aims, we train pattern-based models using data recorded by a temporal bone simulator. We create one model to predict the current stage of the procedure and separate stage-specific models to provide human-friendly feedback within each stage. We use 27 temporal bone simulation runs conducted by 7 expert ear surgeons and 6 trainees to train and evaluate our models. The results of our evaluation show that the proposed system identifies the stage of the procedure correctly and provides constructive feedback to assist surgical trainees in improving their technique.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Human-robot collaboration has already been studied in the industry, for ergonomics and efficiency purposes, but more from a safety than from an acceptability point of view. In this work, we focused on how people perceive robots in a collaboration task and we proposed to use virtual reality as a simulation environment to test different parameters, by making users collaborate with virtual robots. A simple use case was implemented to compare different robot appearances and different robot movements. Questionnaires and physiological measures were used to assess the acceptability level of each condition with a user study. The results showed that the perception of robot movements depended on robot appearance and that a more anthropomorphic robot, both in its appearance and movements, was not necessarily better accepted by the users in a collaboration task. Finally, this preliminary use case was also the opportunity to guarantee the relevance of using such a methodology --- based on virtual reality, questionnaires and physiological measures --- for future studies.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.
