Abstract

A Virtual Reality (VR) glove and a VR system are disclosed. The VR glove includes a glove body and a detector, the detector includes a housing having an accommodation space therein, a piezoelectric member having a first side fixed at a first side in the accommodation space, and a wire connected to the piezoelectric member and extending through a hole provided at a second side of the housing, and the wire is attached to any one finger of a plurality of fingers included in the glove body.

First claim

What is claimed is:

1. A Virtual Reality (VR) glove comprising:
a glove body; and
a detector,
wherein the detector includes:
a housing having an accommodation space therein;
a piezoelectric member having a first side fixed at a first side in the accommodation space; and
a wire connected to the piezoelectric member and extending through a hole provided at a second side of the housing,
wherein the wire is attached to any one finger of a plurality of fingers included in the glove body,
wherein the piezoelectric member includes:
a substrate;
a piezoelectric film having a first side attached on the substrate; and
a film having a first side attached on a second side of the piezoelectric film, and the wire is attached to a second side of the film.

2. The VR glove of claim 1 , wherein the first side of the piezoelectric member is fixed at the first side in the accommodation space through a wire having elasticity.

3. The VR glove of claim 1 , wherein the piezoelectric member further includes a substrate electrode attached to the first side of the piezoelectric film, and
the substrate electrode is electrically connected with a conductive wire.

4. The VR glove of claim 3 , further comprising a communication unit,
wherein the communication unit transmits an electrical signal that is transmitted from the conductive wire to an external computing device.

5. The VR glove of claim 1 , wherein the piezoelectric member further includes a cover attached to the substrate while covering at least a portion of the piezoelectric film, and
the cover and the substrate are attached using a PET tape having a thickness larger than a thickness of the piezoelectric film.

6. The VR glove of claim 1 , wherein, in order to detect extension-flexion movement of any one finger of the plurality of fingers, the wire is attached to a segment of the any one finger.

7. The VR glove of claim 1 , wherein, in order to detect abduction-adduction movement between a thumb and an index finger of the plurality of fingers, the wire is attached to a proximal segment of the thumb.

8. The VR glove of claim 1 , wherein, in order to detect abduction-adduction movement of an index finger and a middle finger of the plurality of fingers, the wire is attached to a proximal segment of the index finger.

9. The VR glove of claim 1 , comprising a plurality of detectors,
wherein each of the plurality of detectors accommodates at least one piezoelectric member,
three wires of a plurality of wires connected with a plurality of piezoelectric members, respectively, are connected to segments of an index finger, respectively, to detect extension-flexion movement of the index finger, and
three other wires of the plurality of wires are connected to segments of a middle finger, respectively, to detect extension-flexion movement of the middle finger.

10. The VR glove of claim 9 , wherein a first wire of the plurality of wires is connected to a proximal segment of the index finger to detect abduction-adduction movement of the index finger, and
a second wire of the plurality of wires is connected to a proximal segment of a thumb to detect abduction-adduction movement of the thumb.

11. The VR glove of claim 1 , wherein the wire is attached such that predetermined tension is applied to the wire when the glove body is worn on a user.

12. The VR glove of claim 11 , wherein the wire is attached to a proximal segment of an index finger with the index finger and a middle finger maximally open.

13. The VR glove of claim 11 , wherein the wire is attached to a proximal segment of a thumb with the thumb and an index finger maximally open.

14. A Virtual Reality (VR) glove comprising:
a glove body; and
a detector,
wherein the detector includes:
a housing having an accommodation space therein;
a piezoelectric member having a first side fixed at a first side in the accommodation space; and
a wire connected to the piezoelectric member and extending through a hole provided at a second side of the housing,
wherein the wire is attached to any one finger of a plurality of fingers included in the glove body, and
wherein, in order to detect extension-flexion movement of any one finger of the plurality of fingers, the wire is attached to a segment of the any one finger.

15. A Virtual Reality (VR) glove comprising:
a glove body; and
a detector,
wherein the detector includes:
a housing having an accommodation space therein;
a piezoelectric member having a first side fixed at a first side in the accommodation space; and
a wire connected to the piezoelectric member and extending through a hole provided at a second side of the housing,
wherein the wire is attached to any one finger of a plurality of fingers included in the glove body, and
wherein, in order to detect abduction-adduction movement between a thumb and an index finger of the plurality of fingers, the wire is attached to a proximal segment of the thumb.
