Walking-in-place (WIP) is a locomotion technique that enables users to "walk infinitely" through vast virtual environments using walking-like gestures within limited physical space. This paper investigates alternative interaction schemes for WIP, addressing successively the control, input, and output of WIP. First, we introduce novel height-based control increase advanced speed. Second, input system WIP based on elastic passive strips. Third, use pseudo-haptic feedback as meant alter walking...

In underwater environments, the reflected ultrasonic waves from objects generally provide more than just information about their color and shape for object recognition. Previous studies have overlooked influence of pose on these wave components. It is crucial to investigate how poses affect components because can vary widely are often unpredictable in real-world scenarios. this work, we introduce a novel dataset comprising collected made various materials observed angles. We also show...

Hap'n'Roll is a wearable device that leverages the concept of scroll to present, with single motor, tactile sensations various sizes, shapes, and textures. composed two axes, sheet, one motor. By changing number sheet wraps, thickness within user's hand can be adjusted. Additionally, using holes on secure fingertips, it present wide range sizes shapes. Unlike typical existing handheld shape-changing devices, not limited cylindrical forms. Furthermore, by moving different materials attached...

Systems with occlusion capabilities have gained interest in augmented reality, vision augmentation, and image processing. To address the challenge of creating a precise yet lightweight system, we introduce novel architecture to tackle blurriness due defocusing. Our approach, utilizing dynamic pinhole array on transmissive spatial light modulator (SLM) positioned between eye layer, offers adaptive patterns, gaze-contingent functionality, potential reduce visual artifacts. preliminary result...

Implementing an autonomous agent on a social VR platform where many users share space requires diverse information. In particular, it is required to recognize the distance from other users, their orientation toward each other, avatar's pose, and text voice messages, behave accordingly. This paper proposes API obtain above information "Cluster," multi-device in operation, that uses API. We have implemented this using network proxy. The can connect ChatGPT [7] conversation real time. measured...

To create rich experiences in virtual reality (VR) environments, it is essential to define the behavior of objects through programming. However, programming 3D spaces requires a wide range background knowledge and skills. Although Large Language Models (LLMs) have provided support, they are still primarily aimed at programmers. In metaverse platforms, where many users inhabit VR spaces, most unfamiliar with programming, making difficult for them modify environment easily. Existing LLM-based...

In Virtual Reality, self-touch (ST) stimulation is a promising method of sense body ownership (SoBO) induction that does not require an external effector. However, its applicability to dysmorphic bodies has been explored yet and remains uncertain due the requirement provide incongruent visuomotor sensations. this, paper, we studied effect ST on hands via haptic retargeting, as compared classical external-touch (ET) stimulation, SoBO. Our results indicate can induce similar levels SoBO than...

Pinching is a common gesture primarily used for zooming on mobile devices, and previous studies considered utilizing it as mid-air in AR/VR. As opposed to touch screens, there no physical contact point between the display fingers pinching, which means positional relationship target users' finger movement pinching could be different from that of screens. In this study, we investigated estimate hand posture, found was significantly off towards thumb away index (approximately 7% offset). This...
