“…While most solutions in this section do not provide unrestricted mobility and positional displacement for haptic interfaces with force-feedback in virtual environments, our own project addresses this limitation. We have developed hardware by modifying the 3D Systems Touch haptic device, integrated with software using the Unity game engine and low-level device drivers [32]. This combination enables medium-scale force display in mobile XR applications, allowing enhanced interaction and mobility within virtual environments.…”

This chapter presents the development of a wearable force-feedback mechanism designed to provide a free-range haptic experience within the spectrum of Extended Reality (XR). The proposed system offers untethered six degrees-of-freedom and small- to medium-scale force-feedback, enabling users to immerse themselves in haptic interactions within virtual environments. The hardware comprises a modified 3D Systems Touch haptic device, driven by software that allows for ambulatory exploration of various haptic aspects. Two experiments were conducted to evaluate the precision, ergonomics, stability, usability, user experience, and performance of the system. Despite indication of software and hardware deficiencies, the results highlight the potential of combining haptic force-feedback and ambulatory XR to enhance immersion in free-range virtual environments. Furthermore, the integration of Mixed Reality pass-through enables users to seamlessly merge real-world environments with augmenting virtual elements. This extension contributes to the exploration of new possibilities for immersive and interactive experiences within mixed reality applications. Future research can delve deeper into the prototype’s potential, further unlocking opportunities for haptic-enabled ambulatory XR experiences and pushing the boundaries of immersive technologies.

Virtual reality technology brings a new experience to human-computer interaction, while wearable force feedback devices can enhance the immersion of users in interaction. This paper proposes a wearable fingertip force feedback device that uses a tendon drive mechanism, with the aim of simulating the stiffness characteristics of objects within virtual scenes. The device adjusts the rotation angle of the torsion spring through a DC motor, and then uses a wire to convert the torque into a feedback force at the user’s index fingertips, with an output force of up to 4 N and a force change rate of up to 10 N/s. This paper introduces the mechanical structure and design process of the force feedback device, and conducts a mechanical analysis of the device to select the appropriate components. Physical and psychological experiments are conducted to comprehensively evaluate the device’s performance in conveying object stiffness information. The results show that the device can simulate different stiffness characteristics of objects, and users can distinguish objects with different stiffness characteristics well when wearing the force feedback device and interacting with the three-dimensional virtual environments.

The research lays the groundwork for further advancements in VR technology, aiming to develop devices capable of interpreting sign language into speech via intelligent systems. The uniqueness of this study lies in utilizing the Meta Quest 2 VR device to gather primary hand sign data, subsequently classified using Machine Learning techniques to evaluate the device's proficiency in interpreting hand signs. The initial stages emphasized collecting hand sign data from VR devices and processing the data to comprehend sign patterns and characteristics effectively. 1021 data points, comprising ten distinct hand sign gestures, were collected using a simple application developed with Unity Editor. Each data contained 14 parameters from both hands, ensuring alignment with the headset to prevent hand movements from affecting body rotation and accurately reflecting the user's facing direction. The data processing involved padding techniques to standardize varied data lengths resulting from diverse recording periods. The Interpretation Algorithm Development involved Recurrent Neural Networks tailored to data characteristics. Evaluation metrics encompassed Accuracy, Validation Accuracy, Loss, Validation Loss, and Confusion Matrix. Over 15 epochs, validation accuracy notably stabilized at 0.9951, showcasing consistent performance on unseen data. The implications of this research serve as a foundation for further studies in the development of VR devices or other wearable gadgets that can function as sign language interpreters.
