1. Field of the Invention
The present invention relates to a glove, and more particularly, to a glove for operating a capacitive touch panel.
2. Descriptions of the Related Art
A touch panel is a device disposed adjacent to a display, which can be controlled by a slight touch from a finger or a stylus so as to transmit data or read a message. As being convenient to use, touch panels have found wide application in various fields, for example, in portable electronic products, automatic teller machines (ATMs), industrial control systems and information inquiry machines. In terms of the induction principle, touch panels are classified into capacitive touch panels, resistive touch panels, electromagnetic touch panels and infrared touch panels. Capacitive touch panels can be operated simply by being touched slightly and touch from a finger causes little wear to such panels, so they have become much popular in recent years.
The capacitive touch panel makes use of electrostatic coupling between a human body and an electric field of the touch panel to determine coordinates according to an induced current. Hence, when a user wears a glove because of cold weather or other reasons, the user will be unable to operate the capacitive touch panel. For this reason, the glove worn by the user must be conductive in order for the user wearing the glove to operate the conductive touch panel.
Referring to FIG. 1, a conventional capacitive touch glove 1 comprises an inner layer 11, an outer layer 13 and a plurality of holes 15. The inner layer 11 is a conductive layer, and the outer layer 13 is made of an elastic material and is adapted to cover the inner layer 11. The holes 15 are formed on fingertip parts of the outer layer 13, and a user can peel the elastic outer layer 13 from the holes 15 so that the inner layer 11 is exposed from the outer layer 13. Because the outer layer 13 has to be peeled off prior to use, this glove is much inconvenient to use; furthermore, because an insulating layer exists outside the conductive inner layer 11, such problems as poor contact or inaccurate positioning are liable to occur when a touch panel is pressed by a finger of the user.
In another conventional glove for operating a capacitive touch panel, a palm portion and finger-root portions of the glove are made of a common glove material, but fingertip portions of the glove are made of conductive yarns. Therefore, the fingertip portions for operating the touch panel are conductive and, thus, are suitable to operate the capacitive touch panel. However, as the conductive yarns are more expensive than common yarns, such a glove is costly to manufacture.
In view of this, there is an urgent need in the art to provide a glove which can be conveniently used to operate a capacitive touch panel with high operational accuracy and is cheap to manufacture.
An objective of the present invention is to provide a glove, which can be conveniently used to operate a capacitive touch panel with high operational accuracy and is cheap to manufacture. Thereby, a user can accurately operate a touch panel of the capacitive touch panel even when the use wears the glove.
To achieve the aforesaid objective, the glove of the present invention comprises a glove body and a plurality of conductive parts. The glove body has a plurality of fingertip parts, and the conductive parts are disposed to penetrate through the fingertip parts so that a fingertip of a user can couple with and control the capacitive touch panel through one of the conductive parts.
The detailed technology and preferred embodiments implemented for the subject invention are described in the following paragraphs accompanying the appended drawings for people skilled in this field to well appreciate the features of the claimed invention.
FIG. 1 is a schematic view of a conventional capacitive touch glove; and
FIG. 2 is a schematic view of a glove according to an embodiment of the present invention.
In the following description, a glove of the present invention will be explained with reference to an embodiment thereof. It shall be appreciated that, this embodiment of the present invention is not intended to limit the present invention to any specific environment, applications or particular implementations described in this embodiments. Therefore, description of the embodiment is only for purpose of illustration rather than to limit the present invention.
Firstly, referring to FIG. 2, a schematic view of a glove 2 according to a preferred embodiment of the present invention is shown therein. The glove 2 is used to operate a capacitive touch panel. The capacitive touch panel comprises a touch panel and a microcontroller electrically connected to the touch panel.
The glove 2 of this embodiment comprises a glove body 21 and a plurality of conductive parts 25. The glove body 21 has a plurality of fingertip parts 23, and at least one of the fingertip parts 23 is provided with a conductive part 25 which is a conductive thread sewn through on the at least one fingertip parts 23. In this embodiment, each of the five fingertip parts 23 of the glove 2 is provided with a conductive part 25 sewn through on the fingertip parts 23.
When the glove assembly 2 of this embodiment is worn by a user, because of the conductive property of the conductive parts 25, the static electricity in the fingertips of the user can be coupled with an electric field on the touch panel of the capacitive touch panel; and then, a corresponding position is computed by the microcontroller electrically connected to the capacitive touch panel. Thereby, the capacitive touch panel can be operated and controlled. It shall be appreciated that, the glove of the present invention can be used directly upon being worn without need of any preparations.
Furthermore, the conductive parts of the glove of the present invention may be in form of a pattern, for example, a thread shape, a geometric shape, a flower shape or an arrow shape. As shown in FIG. 2 which corresponds to this embodiment, each of the conductive parts 25 is of a flower shape and is sewn as a protrusion 27. When the user wears the glove of the present invention, the protrusions 27 of the conductive parts 25 can reduce a contact area with the panel of the capacitive touch panel, which facilitates the user to choose a desired position more accurately when operating the capacitive touch panel.
The glove body 21 of the glove 2 of the present invention may be just a common glove and needs no particular processing. Therefore, any design in appearance of the glove body 21 that is favored by a user can be adopted to cater for different needs of various users. However, depending on needs of the users, the glove body 21 of the glove of the present invention may also be made of a waterproof material (e.g., silica gel) for waterproof purpose.
A conductive thread used for the conductive parts 25 of the glove 2 of the present invention may be at least one of stainless steel fiber, carbon fiber, sputtered fiber and combinations thereof. Preferably, the conductive thread comprises polyethylene terephthalate (PET) in an amount of 80%. Compared to a conductive yarn of the prior art, this conductive thread is lower in cost and is easier to be sewn, so both the raw material cost and the production cost can be significantly reduced.
Accordingly, compared to the conventional glove for operating a capacitive touch panel, the glove of the present invention is lower in cost, more convenient to use and allows for more accurate operation; moreover, if necessary, the glove of the present invention can also be made to be waterproof to cater for needs of users. Therefore, the glove of the present invention can not only overcome the problems of the prior art effectively, but also improve the competitive power of capacitive touch panel products.
The above disclosure is related to the detailed technical contents and inventive features thereof. People skilled in this field may proceed with a variety of modifications and replacements based on the disclosures and suggestions of the invention as described without departing from the characteristics thereof. Nevertheless, although such modifications and replacements are not fully disclosed in the above descriptions, they have substantially been covered in the following claims as appended.
