In the past two decades, Argo Program has collected, processed and distributed over million vertical profiles of temperature salinity from upper kilometers global ocean. A similar number subsurface velocity observations near 1000 dbar have also been collected. This paper recounts history Program, its aspiration arising out World Ocean Circulation Experiment, to development implementation instrumentation telecommunication systems, various technical problems encountered. We describe data...
This paper focuses on design of a dexterous anthropomorphic robot where the operator can perceive transferring bodily consciousness to slave during tele-operation. Accordingly, we propose telexistence surrogate called "TELESAR V", which was designed and constructed by development following: 52 DOF with torso, upper limbs, hands head model operator's posture all parts body maintain 6 accuracy in arm endpoint; HD Head mounted display point view for wide angle stereovision; mechanism sensing...
We developed novel haptic interfaces, FlexTorque and FlexTensor that enable realistic physical interaction with real Virtual Environments. The idea behind is to reproduce human muscle structure, which allows us perform dexterous manipulation safe environment in daily life. suggests new possibilities for highly realistic, very natural virtual environments. There are no restrictions on the arm movement, it not necessary hold a object during objects reality. Because system can generate strong...
"Haptic Telexistence" provides highly realistic haptic interaction among humans and objects located in remote places. We have developed innovative devices constructed a master-slave system to realize Telexistence". Human will be dramatically improved by this concept that perceives us the properties of an object.
Transmission of the distribution force vectors on a fingertip improves stability given operation in tele-operation system. As such, we seek representation via an electrotactile display. The display directly activates nerve fibers connected to mechanoreceptors, thereby representing tactile sensation. system has simple structure, is easily controlled and, it seen number different applications. However, majority conventional displays only present symbolic sensation contact. In this paper,...
Telexistence is fundamentally a concept named for the general technology that enables human being to have real-time sensation of at place other than where he actually exist, and interact with remote environment [Tachi et al. 1990]. We achieved human-like neck movements visually object in 3 dimensional space through previous versions TELESAR [Watanabe 2007]. introduce "TELESAR V" which maps user's spinal neck, head arm into dexterous slave robot allowing operator feel robot's body as his own...
We propose a thermal display that presents rapid temperature change using spatially divided hot and cold stimuli. The exploits two characteristics of human perception: spatial summation the adapting temperature. Experimental results confirmed users perceived separate individual stimuli as single stimulus because summation. Our successfully made skin simultaneously more sensitive to both by stimuli, each which separately adjusts so it enables perceive sensation rapidly. we fabricated enabled...
It is expected that the use of haptic sensors to measure magnitude, direction, and distribution a force will enable robotic hand perform dexterous manipulations. Therefore, we have developed new type finger-shaped sensor can three-dimensional vector field over contact surface. The consists transparent elastic body, two layers internal blue red markers, CCD camera capture movements markers. Using theory, calculate from captured However, theory cannot be applied because its complicated shape....
In this paper we propose a new computer-human interface which uses the back of hand for pointer control.
This report proposes a thermal media system, ThermOn, which enables users to feel dynamic hot and cold sensations on their body corresponding the sound of music. Thermal sense plays significant role in human recognition environments influences emotions. By employing music experience, also greatly affects emotions, we have successfully created new medium with an unprecedented emotional experience. With user feels enhanced excitement comfort, among other responses. For initial prototype,...
In this paper, we propose a haptic transmission system for telexistence to improve the ability sense presence of remote objects. This can transmit information about existence and surface textures objects in locations. The consists conjugated sensor display. on robot's finger detects pressure, vibration, temperature object, display provides above operator's finger. Based information, operator understand what he/she is touching whether its hard or soft, cold hot, smooth rough. With use our...
The goal of this study is to develop a haptic interface for dexterous manipulation. To achieve this, we proposed electrotactile-kinesthetic integration. Our electrotactile display presents natural touch sensations objects. In addition, so small that it considered not affect the moving range fingers. manipulation realized by mounting on kinesthetic having wide workspace. integrated used actively. Therefore, actively evaluated performances single-fingered prototype system. results revealed...
Thermal displays have been applied in various haptic applications, from material simulation to interpersonal communication; however, there is insufficient knowledge about the temporal processing human thermal sense provide a basis for display design. In this study, we investigated physical-perceptual correspondence dynamic stimulation shed light on of sense. experiments, participants reported subjective timings temperature onset and peak continuous changes thenar eminence. We found that was...
Limited data exist regarding association between physical performance and in-hospital falls. This study was performed to investigate the falls in a high-risk population.
Our aim is to afford a remote person the opportunity participate virtually in some event by using surrogate robot communicate with local participants while moving about freely at venue. Accordingly, we propose mutual telexistence system, called TELESAR4, which was designed and constructed development of following: an immersive audiovisual system; omnidirectionally mobile arm hand; omnidirectional stereo camera system (VORTEX); head retroreflective screen for embodiment participant;...
In this paper we propose a new computer---human interface which uses the back of hand for pointer control.
A thermal change on a fingertip is essential for haptic perception. We have proposed vision-based sensor using thermo-sensitive paint and CCD camera telexistence. The employed to measure information the basis of its color, which changes according temperature. can simulate physical interaction between human an object in order surface correctly. Furthermore, because be easily integrated with our force sensor, comprehensive measurement device measuring realized. In this study, we constructed...
Nano force sensors based on passive diamagnetic levitation with a macroscopic seismic mass are possible alternative to classical Atomic Force Microscopes when the bandwidth be measured is limited few Hertz. When an external unknown applied levitating mass, this one acts as transducer that converts input into displacement output signal. Because little damped and long transient response of kind can not neglected, it then necessary deconvolve correctly estimate force. The deconvolution approach...
