Design of 3D Microgestures for Commands in Virtual Reality or Augmented Reality

Virtual and augmented reality (VR, AR) systems present 3D images that users can interact with using controllers or gestures. The design of the user input process is crucial and determines the interactive efficiency, comfort, and adoption. Gesture-based input provides a device-free interaction that may improve safety and creativity compared to using a hand controller while allowing the hands to perform other tasks. Microgestures with small finger and hand motions may have an advantage over the larger forearm and upper arm gestures by reducing distraction, reducing fatigue, and increasing privacy during the interaction. The design of microgestures should consider user experience, ergonomic principles, and interface design to optimize productivity and comfort while minimizing errors. Forty VR/AR or smart device users evaluated a set of 33 microgestures, designed by ergonomists, and linked them to 20 common AR/VR commands based on usability, comfort, and preference. Based primarily on preference, a set of microgestures linked to specific commands is proposed for VR or AR systems. The proposed microgesture set will likely minimize fatigue and optimize usability. Furthermore, the methodology presented for selecting microgestures and assigning them to commands can be applied to the design of other gesture sets.

Computer Interaction

Virtual Reality, Augmented Reality and other such immersive environments have gained popularity with the increase in technological trends in the past decade. As they became widely used, the human computer interface design and the designing criteria emerges as a challenging task. Virtual and Augmented Reality provide a wide range of applications ranging from a primitive level like improving learning, education experiences to complex industrial and medical operations. Virtual reality is a viable alternative that can be focussed on, in the future interface design development because it can remove existing generic and complex physical interfaces and replace them with an alternative sensory relayed input form. It provides a natural and efficient mode of interaction, that the users can work with.Virtual and Augmented reality eradicates the need for development of different acceptable standards for user interfaces as it can provide a whole and generic interface to accommodate the work setting.In this paper, we investigated various prospects of applications for user interaction in Virtual and Augemnted realities and the limitations in the respective domains. The paper provides an outline on how the new era of human computer interaction leading to cognition-based communications, and how Virtual and Augmented realities can tailor the user needs and address the future demands which replaces the need for command-based interaction between the humans and computers.

The article deals with the approach to developing an advertising multimedia product for the promotion or sale of goods or services. Under the advertising product is an advertising video, an interactive commercial, 3-D advertising, virtual and augmented reality, an online store. Based on the analogy method, a diagram of the process of perceiving the advertising multimedia product by the user is presented. The use of the hybrid approach of customer development for updating the multimedia product and taking into account the virtual values of users is substantiated. Developed scenarios for the development of a multimedia product, depending on the results of achieving the planned goals. The sequence of multimedia product development is proposed based on the convergence of face-to-face and screen-to-screen approaches.

Forest firefighting missions encompass multiple tasks related to prevention, surveillance, and extinguishing. This work presents a complete survey of firefighters on the current problems in their work and the potential technological solutions. Additionally, it reviews the efforts performed by the academy and industry to apply different types of robots in the context of firefighting missions. Finally, all this information is used to propose a concept of operation for the comprehensive application of drone swarms in firefighting. The proposed system is a fleet of quadcopters that individually are only able to visit waypoints and use payloads, but collectively can perform tasks of surveillance, mapping, monitoring, etc. Three operator roles are defined, each one with different access to information and functions in the mission: mission commander, team leaders, and team members. These operators take advantage of virtual and augmented reality interfaces to intuitively get the information of the scenario and, in the case of the mission commander, control the drone swarm.

Meta Analyses

Background: The application of virtual and augmented reality technologies to orthopaedic surgery training and practice aims to increase the safety and accuracy of procedures and reducing complications and costs. The purpose of this systematic review is to summarise the present literature on this topic while providing a detailed analysis of current flaws and benefits. Methods: A comprehensive search on the PubMed, Cochrane, CINAHL, and Embase database was conducted from inception to February 2021. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. The Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomized Studies (MINORS) was used to assess the quality and potential bias of the included randomized and non-randomized control trials, respectively. Results: Virtual reality has been proven revolutionary for both resident training and preoperative planning. Thanks to augmented reality, orthopaedic surgeons could carry out procedures faster and more accurately, improving overall safety. Artificial intelligence (AI) is a promising technology with limitless potential, but, nowadays, its use in orthopaedic surgery is limited to preoperative diagnosis. Conclusions: Extended reality technologies have the potential to reform orthopaedic training and practice, providing an opportunity for unidirectional growth towards a patient-centred approach.
