Previous studies on navigation for walking have mainly used visual or acoustic sensations, which are not intuitive and can even be dangerous because they may block auditory information from the surrounding environment. Some other tactile stimulation, is more less annoying, hand arm to generate a pseudo-pulling force [1][2][3]. However, devices tended become large heavy. Maeda [4] achieved walk by using Galvanic Vestibular Stimulation, but such electrical stimulation head has some clinical...

In audio-visual entertainment such as listening to music, game playing, and viewing movies, people frequently seek a richer experience. However the improvement in experience that can be obtained by improving audio visual quality is reaching its limit.

There have been many proposals that added haptic stimulation to entertainment content such as music, games, and movies. These technologies enrich the quality of experiences by improving reality thereof. In contrast, we present a novel approach these facilitating emotional feeling evoked content. this paper, focus on piloerection, which is kind involuntary reaction. Our hypothesis not only it an "reaction", but can also work "input" enhances emotion itself. We constructed device controls...

Augmented reality (AR) optical-see-through (OST) head-mounted displays (HMD) have developed to a point where browsing information on the go is possible. In this paper, we investigate readability of text an AR HMD while user walking. There are two common methods displaying HMD: anchoring screen coordinate system or world system. We report results laboratory experiments comparing when displayed in these systems, and participants walked treadmill. first experiment, read letter strings...

In television shows, we are familiar with the sound of artificial laughter, so called "canned laughter" or "laugh track". It generally has an enhancing effect on viewer's desire to laugh. However, if is played when user dislikes content, it works negatively. To cope this problem, propose a system that produces laugh track synchronized user's We use myoelectric signal from diaphragmatic muscle detect initial laugh, and dolls around produce sound. speculated although trigger necessary, can...

Visual signs and audio cues are commonly used for pedestrian control in the field of general traffic research. Because pedestrians need to first acquire then recognize such cues, time delays invariably occur between cognition action. To better cope with this issue delays, wearable devices have been proposed more intuitively. However, attaching removing can be cumbersome impractical. In study, we propose a new visual navigation method using Vection Field which optical flow is presented on...

A gaze input interface offers hands-free operation by using the view-point position as cursor coordinates on display. However, selection of a button is indistinguishable from viewing; this known Midas touch problem. We propose new method that measures divergence eye movement, thereby enabling users to "press" moving their viewpoint forward. Comparison our and conventional blinking confirms speed accuracy are similar.

Learning a new language is difficult and time-consuming. Apart from dedicated classroom study, second (L2) learners often lack opportunities to switch their attention vocabulary learning over other daily routines. In this work, we propose method that enables L2 study items during dead time, such as when commuting school or work. We developed smartphone application, VocaBura, which combines audio with location-relevant L1-L2 word pairs allow users discover while walking past buildings, shops...

We have developed the Pixel-level Visible Light Communication (PVLC) projector based on DLP (Digital Processing) system. The can embed invisible data pixel by into a visible image to realize augmented reality applications. However, it cannot update either or contents in real time. In order solve problem, we improve so that PC dynamically control system and enable us achieve high-frame-rate feature resolution conversion. This paper proposes framework design method for reconfigurable PVLC projector.

With the aim of augmenting auditory sensation by tactile stimuli, we investigated cross-modal relationships between two modalities, focusing on frequency. The results showed that frequency consonance and audio stimuli depends relationship harmonics, in a manner similar to waves, but with broader peaks.

This paper proposes a new shadow interface system that provides tactile feedback from user's to physical body. When users obstruct the projected image by their bodies, wearable photoreactive displays receive light information; they decode it and transmit sensation. The proposed does not require complex sensing, complicated settings communication systems; can perform high speed with information directly received light. Perspective projection of occluding objects generate shadows is preserved...

Collaboration between computer graphics and multiple robots has attracted increasing attention in several areas. To preserve the seamless connection them, system needs to be able accurately determine position state of control them easily instantly. However, realizing a responsive for large number mobile without complex settings at same time avoiding load problem is not trivial. Our system, called "Phygital Field", can project two types information: visible images humans data patterns...

In this paper, we propose a novel stick-type interface, the "HaCHIStick," for musical performance on tablet PC. The HaCHIStick is composed of stick with an embedded vibrotactile actuator, visual display, and elastic sheet display. By combining kinesthetic sensation induced by striking sensation, system provides natural haptic cues that enable user to feel what they strike stick, such as steel or wood. This interaction would enrich user's experience when playing instruments. interface...

Dihedral corner reflector arrays (DCRAs) are imaging devices that form real images and used in a variety of applications, including floating virtual touchscreens image presentation around physical objects. However, they induce several types degradations to images. It is desirable suppress these provide better viewing experiences. This paper proposes method suppressing which appear as high-frequency noise by using mechanical vibration. The effects vibrating the DCRA were confirmed through an...

Nobody likes to imagine that insects are crawling over them. Many of us would become horrified realize a feeling ticklishness on the skin was caused by insects. However, many have had experience playing with ants when we were children. This might indicate an apparently disagreeable sensation can sometimes changes being funny, thrilling, or even pleasant experience. The aim our work is highlight this fact, and create new entertainment have, named “Ants in Pants” (Figure 1). system composed...

In recent years, touch panels have become widespread as an intuitive means to activate device operations. Because the panel has a space over which finger and corresponding cursor moves, certain actions compared force input-type devices such pointing stick. If we could add illusory feeling of motion with input interface, it would more intuitive. We found new haptic illusion "motion", occurs when electrical tactile flow is presented on fingertip while experiencing shearing force. also...

Public pathways, in areas such as stations and concert halls, can present pedestrian crowds with difficulties, for example, congestions collisions (Figure 1-a). Although visual signs audio cues are commonly used smoother flow, they often ignored or neglected because require some time to be understood. For more intuitive navigation, wearable devices have been proposed, of which induce motion using a haptic device [Kojima et al. 2009] vestibular stimuli [Maeda 2005]. However, these personal...
