Abstract

Provided is a data glove which imparts little discomfort when worn, and is capable of accurately detecting movement of a hand. The data glove includes 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 two strain sensors 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 includes a plurality of stretch prevention parts which limit the elongation of the glove main body.

Claims

1. A data glove, comprising:

a glove body; and

a plurality of strain sensors that detect stretch and contraction of the glove body, the strain sensors being each provided in a region corresponding to at least one finger of first to fifth fingers, on a dorsal side of the glove body, wherein

at least two of the strain sensors are provided to each of the at least one finger;

the plurality of strain sensors comprise a first strain sensor and a second strain sensor that detect stretch and contraction of the glove body in a proximal-distal direction, the first and second strain sensors being each provided in a region corresponding to a proximal interphalangeal joint and a region corresponding to a metacarpophalangeal joint, of at least one finger of the second to fifth fingers, on the dorsal side of the glove body; and

the date glove further comprises a plurality of stretch-restraining portions that restrain stretch of the glove body, the stretch-restraining portions being each provided in a region corresponding to an area between metacarpophalangeal joints along the proximal-distal direction, on the dorsal side of the glove body.

2. The data glove according to claim 1, wherein

the plurality stretch-restraining portions extend in the proximal-distal direction on an inner surface side of the dorsal side of the glove body, where the inner surface of the dorsal side of the glove body denotes a surface side in contact with a hand of a wearer of the glove body when the glove body is worn.

3. The data glove according to claim 1, wherein

proximal ends of the stretch-restraining portions are located more proximally than the strain sensors, respectively;

and

the data glove further comprises a connection portion that restrains stretch of the glove body, the connection portion being provided so as to bridge the plurality of stretch-restraining portions.

4. The data glove according to claim 1, wherein the stretch-restraining portions are provided to be superposed on wirings extending from the strain sensors, respectively.

5. A data glove, comprising:

a glove body; and

a plurality of strain sensors that detect stretch and contraction of the glove body, the strain sensors being each provided in a region corresponding to at least one finger of first to fifth fingers, on a dorsal side of the glove body, wherein

at least two of the strain sensors are provided to each of the at least one finger;

the plurality of strain sensors comprise a third strain sensor and a fourth strain sensor provided in each region corresponding to a metacarpophalangeal joint of at least one finger of the first to fifth fingers, on the dorsal side of the glove body; and

the third strain sensor is configured to detect stretch and contraction of the region in the proximal-distal direction; and

the fourth strain sensor is configured to detect stretch and contraction of the region in a lateral direction.

6. The data glove according to claim 5, wherein the third strain sensor and the fourth strain sensor are provided so as to intersect each other.

7. The data glove according to claim 6, wherein an intersection angle formed by the third strain sensor and the fourth strain sensor is a substantially right angle.

8. The data glove according to claim 5, wherein the third strain sensor and the fourth strain sensor are provided in a region corresponding to the first finger.

9. A data glove, comprising:

a glove body;

a plurality of strain sensors that detect stretch and contraction of the glove body, the strain sensors being each provided in a region corresponding to at least one finger of first to fifth fingers, on a dorsal side of the glove body, wherein

at least two of the strain sensors are provided to each of the at least one finger; and

another strain sensor that detects stretch and contraction of the glove body in the proximal-distal direction, the another strain sensor being provided in a region along a proximal phalanx of the second or fifth finger, on a palm side of the glove body.
