Redirected Walking on Omnidirectional Treadmill.

Redirected walking (RDW) and omnidirectional treadmill (ODT) are two effective solutions to the natural locomotion interface in virtual reality. ODT fully compresses the physical space and can be used as the integration carrier of all kinds of devices. However, the user experience varies in different directions of ODT, and the premise of interaction between users and integrated devices is a good match between virtual and real objects. RDW technology uses visual cues to guide the user's location in physical space. Based on this principle, combining RDW technology with ODT to guide the user's walking direction through visual cues can effectively improve user experience on ODT and make full use of various devices integrated on ODT. This paper explores the novel prospects of combining RDW technology with ODT and formally puts forward the concept of O-RDW (ODT-based RDW). Two baseline algorithms, i.e., OS2MD (ODT-based steer to multi-direction), and OS2MT (ODT-based steer to multi-target), are proposed to combine the merits of both RDW and ODT. With the help of the simulation environment, this paper quantitatively analyzes the applicable scenarios of the two algorithms and the influence of several main factors on the performance. Based on the conclusions of the simulation experiments, the two O-RDW algorithms are successfully applied in the practical application case of multi-target haptic feedback. Combined with the user study, the practicability and effectiveness of O-RDW technology in practical use are further verified.

Research and practice of high-speed spiral composite drilling technology in complex and weak coal seams

In response to the difficult slag discharge and low hole formation rate encountered in the Wangpo Coal Mine, a study was conducted on high-speed spiral composite drilling technology. This study was integrated with the performance characteristics of the ZDY6000LR-type high-speed pit rig, resulting in the design of drill bits in three different specifications: Φ110/63.5 mm, Φ95/60.3 mm, and Φ88/50 mm. Additionally, the study optimized the three-wing drill pipe's feed speed, rotation speed, and airflow volume. The industrial field test, conducted on the 3206 working face of the Wangpo Coal Mine, resulted in the design of three drill bit combinations that exhibited high strength and stiffness. This design improvement led to enhanced hole integrity, elevated slag removal efficiency, and extended service life for both the drill pipe and bit. The high-speed spiral composite drilling technology, alongside the supporting equipment, effectively addresses the challenges of slag discharge and nozzle top drilling encountered during operations. It significantly improves the deep hole drilling rate, achieving a drilling depth of over 100 m with a success rate exceeding 70%. This technology provides vital support for the extraction of gas from coal seams within the mine. Notably, the Φ95/60.3 mm screw pipe and its corresponding drill bit demonstrated the optimal holeforming effect, with an average hole depth of 111.2 m and a hole formation rate of 90.9%. These findings offer valuable insights for drilling operations under similar conditions of complex and weak coal seams.

Integration of Virtual Reality Technology and Innovative Teaching Practices in Rehabilitation Education and Management

Abstract At present, the scale of rehabilitation medicine professional education is difficult to meet the needs of society, the traditional one-way transmission of the teaching mode is not effective, and there is a lack of standardized personnel training programs. This paper proposes rehabilitation education and management practices based on virtual reality technology. Using 3DMax software, the VR scene for rehabilitation education and management practice was constructed, and the scene’s rendering effect was optimized with the help of the SSAO algorithm. By exploring the teaching function orientation of virtual reality technology, the VR scene can be integrated into rehabilitation teaching in colleges and universities so as to design a rehabilitation management teaching mode based on VR technology. The results show that no matter which dataset, the frame rate of the improved SSAO algorithm is greater than that of the SSAO algorithm, and the difference is specifically shown as 7~15 frames/s. In addition, there are significant differences between the teaching mode of this paper and the traditional teaching mode in terms of the quality of teaching, assessment scores, and satisfaction (P<0.05). The research in this paper can effectively enhance the theory and skill level of students, resulting in better innovation in rehabilitation education and management practice.

Virtual Reality and Surgical Simulation Training for Orthopaedic Surgery Residents: A Qualitative Assessment of Trainee Perspectives.

The demonstrated benefits of virtual reality (VR) in orthopaedic surgical training are numerous. However, it is relatively unknown how best to implement VR into an already established orthopaedic resident education curriculum and how trainees will engage and use these technologies longitudinally. This was an exploratory, qualitative research study performed in accordance with Consolidated Criteria for Reporting Qualitative Research guidelines. Orthopaedic surgery residents at a single institution were recruited during the 2022 to 2023 academic year. Semistructured interviews were conducted. Data were analyzed through grounded theory methodology, beginning with open coding, followed by axial coding, and concluding with selective coding that describes orthopaedic surgery residents' current perceptions of VR as a training tool. Six residents participated in interviews before thematic saturation was achieved. Average interview length was 13:27 (±2:59) minutes. Residents felt that currently, VR is most useful for interns and junior residents as an educational adjunct for learning anatomy, surgical exposures, and the steps of a procedure in a risk- and judgment-free arena. There seems to be a "ceiling effect" with VR given current technological limitations, and residents remarked that there is an associated "opportunity cost" with using VR technology. Some residents may find it more time-efficient to study texts, videos, or surgical guides rather than use VR. Cost (limited number of headsets) and technological barriers (i.e., hardware, software, and Wi-Fi issues) were some of the described barriers to VR utilization. Residents felt that there needs to be dedicated technological support to help with these issues. At this time, given these limitations of VR, many preferred VR as an optional educational adjunct rather than as a required curricular tool or assessment of surgical competency. There is current utility for VR in orthopaedic surgical training. Future technological advances may make VR more central to resident education. This study describes resident perceptions about the technology and best use practices for the technology. Qualitative Study, Level V Evidence.

TECHNOLOGICAL PRACTICES OF REFUSAL: RADICAL REIMAGINATION IN M EIFLER’S COMPUTATIONAL PROSTHETICS

The essay brings together Black feminist theory, critical disability studies, and feminist science and technology studies together through the concept of technological practices of refusal. The concept of technological practices of refusal describes how disabled people engage in everyday, often communal technological practices as means to challenge normative logics and engage in collective world-making practices toward collective liberation and societal transformation. Technological practices of refusal extends Schalk & Kim’s (2020) feminist-of-color disability studies and Campt's (2017) practices of refusal to highlight the interrelations between ableism and white supremacy and the ways in which systems of domination operate to dehumanize individuals based on deviations from white supremacist configurations of race, class, gender and ability. The concept therefore not only underscores how disabled people reimagine and enact new social formations despite the foreclosure of subjectivity and futurity, but maps out new points of affinity for solidarity and collective action.
