    This paper introduces Art Sensorium Project that is founded in Asia AI Institute of Musashino University. A main target of the project is to design and implement a system architecture of unified art collections for virtual art experiences. To provide art experiences, a projection-based VR system, called Data Sensorium, is used to stage art materials in a form of real-sized virtual reality. Furthermore, a system architecture of a multidatabase system for heterogeneous art collection archives is presented, so a set of integrated art data is applied to Data Sensorium for newly generated art experiences.

    When presented with asymmetric vibrations, humans experience an illusory force, similar to the sensation of being pulled in a particular direction. A pulling illusion has also been used in new display elements for a virtual reality content and a pedestrian navigation system. However, the basic design of asymmetric vibration stimuli that can induce this illusion has not yet been determined. In particular, it is unclear as to which part of the vibration waveform should be asymmetric to induce an illusion. To better understand the design of asymmetric vibration stimuli that can induce a pulling illusion, we evaluated the effect of the illusion corresponding to the waveform deformation due to a change in phase difference of asymmetric-vibration frequency components. The results of a psychophysical experiment demonstrate that when the phase differences of the fundamental and second harmonic waves of the asymmetric vibration are close to 0 degrees or -180 degrees, the illusion is more likely to occur. This result implies that the difference in the rate by which the acceleration changes at each polarity contributes to the illusion.

    <p>This study proposes a semi-voluntarily motion presentation system based on the force applied to the arm swing mechanism in a locomotion interface (LI) that can present arm swing motion in addition to foot motion during walking. It is considered that the device can be operated by using the force of the arm swing even when the user cannot move the foot voluntarily. We performed a comparative experiment of walking with the automatic method and walking with the proposed method. As a result, it was confirmed that there was a difference in the rotation angle of the body, and the usefulness of the semi-automatic LI that moves by swinging the arm was confirmed.</p>

  • Tamefusa, Shintaro, Yano, Hiroaki, Tanaka, Naoki, Saitou, Hideyuki, Iwata, Hiroo (担当:分担執筆, 範囲:Motion Improvement for Stairs Climbing and Descending with Gait Rehabilitation System)
    IEEE 2010年1月 (ISBN: 9781424477098)
    This paper describes the development of a gait rehabilitation system with a locomotion interface (LI) for stair climbing or descending. The LI consists of two 2 DOF manipulators equipped with footpads. These can move the user's feet while his or her body remains stationary. The footpads follow the prerecorded motion of the feet of a healthy individual. For gait training, the user progresses iteratively through successively more advanced modes. In this study, three modes, enforced stair climbing/descending, semi-voluntary stair climbing/descending, and real stair climbing/descending were used. Especially gait trajectories for the stairs climbing/descending were improved to realize valid weight shift motion. Comparisons were made between the modes for healthy individuals and a patient. The effectiveness of the system was examined using EMG and foot pressure data.

  • Yano, Hiroaki, Miyamoto, Yuichi, Iwata, Hiroo (担当:分担執筆, 範囲:Haptic Interface for Perceiving Remote Object Using a Laser Range Finder)
    IEEE 2009年1月 (ISBN: 9781424438587)
    This paper describes development of a haptic interface using a laser range finder. The system consists of a laser range finder, a 1 degree-of-freedom haptic apparatus and a computer. The haptic apparatus can generate a reaction force based on a distance to a remote object that is measured by the laser range finder. A user can feel the shape of a remote object by holding this interface and pointing the object. Three haptic rendering algorithms were developed. Through some experiments, the effectiveness of this system was confirmed.

    IEEE COMPUTER SOC 2008年1月 (ISBN: 9781424420056)
    This paper describes development of a haptic sensor and display system that is sensing hardness and temperature of a real object simultaneously and displaying them as a virtual object. The sensor system consists of a force sensor, a linear-encoder, and a thermistor. And the display system is composed of a DC motor, a rotary-encoder, and a planer end effecter which mounts a peltier device. Evaluation of this system was performed through a measurement and display experiment.

    IEEE COMPUTER SOC 2005年1月 (ISBN: 0769523102)
    This paper describes a haptic rendering method for perception of rigidity distribution using a tool-handing type haptic interface. Since the data of rigidity distribution is different from cardinal number data measured with CT or MRI, we can only perceive rigidity value only when we deform it. We developed a rigidity data mapping method like a spring model by considering cross-section of 3D rigidity distribution. We confirmed that our method is effective for rigidity distribution perception.

    IEEE COMPUTER SOC 2004年1月 (ISBN: 0769521126)
    The Food Texture Display is a haptic interface that presents biting force. The taste of food arises from combination of chemical, auditory, olfactory and haptic sensations. Haptic sensation while eating is an unsolved problem in taste display. The Food Texture Display generates a force on the user's teeth to display food texture. The device is composed of four linkages. The mechanical configuration of the device is designed such that it will fit into the mouth, with a force sensor attached to the end effecter The Food Texture Display generates a force representing the force profile captured from the mouth of a person biting real food. Result of experiments showed that the device succeeded in presentation of different food textures.

    The Food Simulator is a haptic interface that presents biting force. The taste of food arises from a combination of chemical, auditory, olfactory and haptic sensation. Haptic sensation while eating has been an ongoing problem in taste display. The Food Simulator generates a force on the user's teeth as an indication of food texture. The device is composed of four linkages. The mechanical configuration of the device is designed such that it will fit into the mouth, with a force sensor attached to the end effecter. The Food Simulator generates a force representing the force profile captured from the mouth of a person biting real food. The device ha been integrated with auditory and chemical display for multi-modal sensations in a taste The Food Simulator has been tested on a large number of participants. The results indicate that the device has succeeded in presenting food texture as well as chemical taste.
