Abstract: Provided is a filamentous strain sensor element capable of detecting a relatively great tensile strain. The strain sensor element of which resistance value changes in response to stretch and to contraction in a longitudinal direction, includes: a first conductive portion that is filamentous and formed from a carbon nanotube bundle; and a second conductive portion that covers a peripheral surface of the first conductive portion and is elastic and conductive, in which the first conductive portion is discontinuous at one or a plurality of positions.

Abstract: Provided is a data glove which imparts little discomfort when worn, and is capable of accurately detecting movement of a hand, comprising: a glove main body; and a plurality of strain sensors which are disposed on the dorsal side of the glove main body in regions corresponding to at least one finger, and which detect stretch and contraction of the glove main body. The strain sensors preferably include a first strain sensor and a second strain sensor which are disposed on the dorsal side of the glove main body to correspond respectively to a proximal interphalangeal joint and a metacarpophalangeal joint of at least one finger of the second through fifth fingers, and which detect stretch and contraction of the glove main body in a proximal-distal direction. The data glove preferably further comprises a plurality of stretch prevention parts which limit the elongation of the glove main body.

Abstract: A control device in one embodiment includes a first transmission unit, a first receiving unit, and a first generation unit. The first transmission unit is configured to transmit first performance data including contents of playing a keyboard instrument at a first communication base to a second communication base. The first receiving unit is configured to receive second performance data from the second communication base. The first generation unit is configured to generate a drive signal to produce a sound in accordance with the second performance data and output the drive signal to a sound generation device at the first communication base. At least one of the first performance data and the second performance data includes a key position signal indicating a key press amount on the keyboard instrument.
