Is it possible to feel part of one’s own body even when the body part is separated from the body? If so, we could exist in different locations by splitting the self-body and using our body in each location. In a study in which the illusion that two bodies are one’s own body was induced using virtual reality (VR), the participants felt as if they we...

The supernumerary robotic limb system expands the motor function of human users by adding extra artificially designed limbs. It is important for us to embody the system as if it is a part of one’s own body and to maintain cognitive transparency in which the cognitive load is suppressed. Embodiment studies have been conducted with an expansion of bo...

Human behavior and perception are optimized for a single body. Yet, the human brain has plasticity, which allows us to extend our body schema. By utilizing technology like robotics or virtual reality (VR), we can modify our body parts or even add a new body to our own while retaining control over these parts. However, the update of body cognition w...

Spatial cues play an important role in navigating people in both physical and virtual spaces. In spatial navigation, visual information with additional cues, such as haptic cues, enables effective guidance. Most haptic devices are applied to various body parts to make mechanical stimuli, while few devices stimulate a head despite the excellent sens...

Recognizing foot gestures can be useful for subtle inputs to appliances and machines in everyday life, but for a system to be useful, it must allow users to assume various postures and work in different spaces. Camera-based and pressure-based systems have limitations in these areas. In this paper, we introduce AnkleSens , a novel ankle-worn foot...

Visual perspective taking is inferring how the world looks to another person. To clarify this process, we investigated whether employing a humanoid avatar as the viewpoint would facilitate an imagined perspective shift in a virtual environment, and which factor of the avatar is effective for the facilitation effect. We used a task that involved rep...

This work presents a method for identifying surgical field states using time-of-flight (ToF) sensors equipped with a surgical light. It is important to understand the surgical field state in a smart surgical room. In this study, we aimed to identify surgical field states by using 28 ToF sensors with a surgical light installed on each. In the experi...

In the medical field, surgical videos can be used to introduce surgical skills. Medical students and residents watch the videos to study the surgical skills and increase learning speed by compensating for the lack of experience in surgical rooms due to limited opportunity to join in surgery. To record egocentric surgical videos by a wearable camera...

Peripersonal space (PPS) is important for humans to perform body–environment interactions. However, many previous studies only focused on the specific direction of the PPS, such as the front space, despite suggesting that there were PPSs in all directions. We aimed to measure and compare the peri-trunk PPS in four directions (front, rear, left, and...

Decision-making process is one of the most critical aspect that determines athletic performance. However in real-world measurement, it is not easy to analyze decision-making independently because many other aspects potentially include athletic behavior. We have established a virtual reality (VR) environment which can allow us to manipulate visual c...

The word “rise” is used to describe the texture of pitching in baseball. In order to clarify the factors by which the batter perceives “rise” for pitching, we analyzed the parameters such as the physical features of the ball and the tempo of the pitching form in relation to the batter's subjective evaluation. We conducted a Two-alternative forced c...

Cyber space enables us to “share” bodies whose movements are a consequence of movements by several individuals. But whether and how our motor behavior is affected during body sharing remains unclear. Here we examined this issue in arm reaching performed by a shared avatar, whose movement was generated by averaging the movements of two participants....
Chapter
Surgical navigation has become essential for surgeons to accurately and safely perform precision surgery. The 3D organ modeling based on individual patient’s medical image data is indispensable for simulation, navigation, and education for accurate and safe surgery. Thus, radiomics is a crucial role in systematically scientizing the enormous amount...

In an operative room, medical images serve as intraoperative navigation or support for surgeons to ensure safe surgery. However, conventional two-dimensional images from drip infusion cholangiography with CT (DIC-CT) or magnetic resonance cholangiopancreatography (MRCP) are difficult to understand the anatomy intuitively. Then, we have developed a...

This paper presents a thin digital full-face mask display that can reflect an entire facial expression of a user onto an avatar to support augmented face-to-face communication in real environments. Although camera-based facial expression recognition technology has enabled people to augment their faces with avatars, application was limited to face-t...

Illusory body ownership can be induced in a body part or a full body by visual-motor synchronisation. A previous study indicated that an invisible full body illusion can be induced by the synchronous movement of only the hands and feet. The difference between body part ownership and the full body illusion has not been explained in detail because th...

Illusory ownership can be induced in a virtual body by visuo-motor synchrony. Our aim was to test the possibility of a re-association of the right thumb with a virtual left arm and express the illusory body ownership of the re-associated arm through a synchronous or asynchronous movement of the body parts through action and vision. Participants fel...

The goal of this research is to propose the e2-MaskZ, a mask-type display that changes the user's face to the face of an avatar. The e2-MaskZ is composed of a face-capture mask to recognize the facial expression, and a face-display mask to present the avatar that reflects the recognize expression of the system wearer. 40 photo reflective sensors ar...
Conference Paper
Supernumerary Robotic Arms (SRAs) can make physical activities easier, but require cooperation with the operator. To improve cooperation, we predict the operator’s intentions by using his/her Facial Expressions (FEs). We propose to map FEs to SRAs commands (e.g. grab, release). To measure FEs, we used a optical sensor-based approach (here inside a...

Reasoning about other people’s mind is important to successful social communication. Visual perspective taking is the basic ability to infer others’ mind, denoting the process of judgment what and how a certain object looks from the others’ viewpoint. Recent research showed that the understanding of how a target appears to another person occurs spo...
