The main contribution is to realize an efficient redirected working (RDW) technique by utilizing haptic cues for strongly modifying our spatial perception. Some research has shown that users can be on a circular arc with radius of at least 22 m without being able detect the inconsistency showing straight path in virtual world. However, this still too large enable presentation demonstration restricted space. Although most RDW techniques only used visual stimuli, we recognize space...

This paper presents a novel interactive system that provides users with virtual reality (VR) experiences, wherein feel as if they are ascending/descending stairs through passive haptic feedback. The stimuli provided by small bumps under the feet of users; these to represent edges in environment. visual and shoes, head-mounted displays, evoke visuo-haptic interaction modifies user's perception floor shape. Our enables experience all types stairs, such half-turn spiral VR setting. We conducted...

Replying to formal emails is time-consuming and cognitively demanding, as it requires polite phrasing ensuring an adequate response the sender's demands. Although systems with Large Language Models (LLM) were designed simplify email replying process, users still needed provide detailed prompts obtain expected output. Therefore, we proposed evaluated LLM-powered question-and-answer (QA)-based approach for reply by answering a set of simple short questions generated from incoming email. We...

Virtual reality (VR) enables beyond-real interactions (BRI) that transcend physical constraints, offering effective user experiences like extending a hand to grasp distant objects. However, adapting novel mappings of BRI often reduces performance and the sense embodiment. To address this, we propose using noisy tendon electrical stimulation (n-TES) decrease proprioceptive precision. Previous studies have suggested attenuating precision is crucial for sensory-motor adaptations. Thus,...

Hand redirection, which subtly adjusts a user's hand movements in virtual environment, can modify perception and movement by providing real-time corrections to motor feedback. In the context of learning rehabilitation, observing replays has been shown enhance function. The application redirection these making appear larger or smaller than they actually are potential improve However, detection threshold for specifically motion replays, remains unclear, as it primarily studied feedback...

This paper proposes a method for improving the effects of redirected walking (RDW) by using haptic cues, particularly discrimination path curvature. Some research has shown that users can be on circular arc with radius at least 22 m without being able to detect inconsistency showing straight in virtual world. However, this is still too large enable presentation demonstration restricted space. We develop an RDW system, which displays visual representation flat wall and virtually walk along it...

In this paper, we present a study of redirected walking (RDW) that shifts the positional relationship between visual and auditory cues during curvature manipulation. It has been shown that, when presented with incongruent spatial localization task, human observers integrate information based on each cue's relative reliability, which determines their final perception target object's location. This multi-modal integration model is known as maximum likelihood estimation (MLE). By altering...

In this paper, we propose a novel redirected walking (RDW) technique that applies dynamic bending and curvature gains so users perceive less discomfort than existing techniques apply constant gains. Humans are likely to notice continuous changes those sudden. Therefore, instead of applying or users, method continuously the We conduct experiments investigate effect in manipulation with regards discomfort. The experimental results show proposed significantly suppresses by up 16 9% for...

There is a growing demand for redirected walking (RDW) techniques and their application to various virtual real environments. To apply appropriate RDW methods manipulation according the environments, controllers are predominantly used. three types of controllers: direct scripted controller, generalized predictive controller. The controller type pre-scripts mapping between employs method quantities certain procedure depending on user's position in relation space. This approach has potential...

In the field of virtual reality, a few methods exist that allow user to walk up and down stairs in environment (VE); however, most them are based on complicated device system generates physical steps using actuators. Because it is difficult for users wearing head mounted displays (HMDs) keep track surrounding environment, walking could prove be very dangerous lead injuries. Further, these systems have disadvantages cannot naturally. Therefore, we present "Infinite Stairs," which novel...

In this study, considering the characteristics of multisensory integration, we examined a method for improving redirected walking (RDW) by adding noise to vestibular system reduce effects inputs on self-motion perception. RDW, contradiction between and visual sensations may make users notice RDW manipulation, resulting in discomfort throughout experience. Because humans integrate information reliability each modality, reducing perception, it is possible suppress awareness during manipulation...

Hand redirection is a technique used in virtual reality (VR) to alter the hand position from real position, enabling extended interaction VR. This capitalizes on visual system's dominance over proprioception, whereby discrepancies between mapping and below specific threshold are indiscernible users. However, these detection thresholds often minute. In this study, we explore impact of haptic stimuli known as 'hanger reflex' redirection, specifically concerning forearm pronation, which...

It is inspired by mirror therapy, where the patient's healthy arm involved in recovering affected arm's motion. By tracking user's head, wrists, and fingers' positions, our approach allows handicapped to control digital avatar order pursue reaching task. apply concept of virtual co-embodiment use information from unaffected complete limb's impaired motion, which added unique feature. This...
