This paper explains and discusses a novel method called virtual light touch contact (VLTC), which helps to mitigate postural sway of the human body. The method involves setting a virtual partition around the user and estimating the virtual force caused when the user touches it. A prototype system was developed using motion-capture technology and a tactile stimulator, and preliminary experiments involving...
Daily continuous spirometry is expected to detect the initial symptoms of lung disease that appear in daily-life situations. Spiro Vest is an e-Textile-based wearable spi-rometer that is suitable for daily continuous spirometry because it does not require uncomfortable attachments, such as the nose-pinching clips and mouthpieces used by typical medical spirometers. However, several adaptation issues...
This paper proposes a passive-type exoskeleton called PEXER IV (Passive Exoskeleton for Easy Running, version IV) as shown Fig. 1 and its design objectives for development. PEXER IV is a wearable-type device, aiming reduction of physical load of a runner. The development of the assistive exoskeleton for running has some difficulties. The exoskeleton must sufficiently exert force to support a part...
In this paper, we propose the method that acquires reaction force using a cane. A humanoid uses the cane in order to prevent falling by deriving optimal cane position and reaction force. We define the optimal cane position as Capture Point (CP). Arranging the cane to CP enable to keep the COG in support polygon even if falling occurs. That is, the robot realizes passive prevention of falling by arranging...
For assisting the elderly or physically challenged walking, a cane robot which be driven by an Omni-directional mobile robot has been proposed. A variety of sensors fixed on the cane robot is used for monitoring user's motion and detecting environment around user. The user's intentions of to which user want to move can be estimated by monitoring the applied force to cane robot, then the cane robot...
