Introduction that enables the wearer to interact

Introduction

With the growing  interests of consumer’s electronic products which are equipped with touchscreens have become popular.                         A touchscreen is an electronic display which can detect the entity of a touch in the display area.                                                      There are a lot of benefits of choosing a display with touchscreen technology.Touch technology make things easier for people who are not good at using technological devices and  it is much faster.Since no keyboard is required,saving valuble place.                                                                      We can classify the touchscreens of smartphones as resistive or capacitive.In this paper, we study capacitive-type panels.

Problem Describing

In recent years,Capacitive-type panels(CTPs) have been using more than resistive- type panels(RTPs) thanks to its multi-touch feature.It enables using more fingers and it makes opportunities for users.A Capacitive touch screen consists of two spaced layers of glass,which are coated with conductor such as Indium Tin Oxide(ITO).                              Human body is an electrical charge conductor.When a finger touches the glass of the capacitive surface,it changes the local electrostatic field .                                                                      The system continuously monitors the movement of each tiny capacitor to find out the exact area where the finger had touched the screen.

                

The problem is, since the technology is dependent on the human body’s conductivity,it doesnt work if the user is wearing gloves.We can make gloves with conductive fingertips.

*What is this Invention ?

A glove that enables the wearer to interact with a capacitive touchscreen without removing the glove has a first portion formed from a non-conductive knitted material and a second portion formed from an electrically conductive yarn. Exemplary is the finger tip portions of the thumb and index finger being formed from the electrically conductive yarn and the remainder of the finger tips being formed from the non conductive yarn. The second, conductive, portion may include a non-conductive yarn with an electrically conductive fiber distributed uniformly therethrough.¹

 

         

 

 

*Field of the Invention

Suitable for using in cold weather and have conductive material at particular partials to utilize a touchscreen.

 

* Detailed Description of Specific Embodiments

The manufacture of gloves is well known. Gloves can be made by providing hand-shaped patterns of material, such as a woven, knitted, felted, or spun-bonded material, and attaching mirror image patterns together, typically by bonding (thermally or adhesively) or by sewing at or near the edges of the patterns.

Alternatively, a glove can be knitted, and various machines are commercially available for knitting gloves. Preferably for this invention, the material used in making the glove is one desirable for making a glove suitable for use in inclement weather, such as cold, wet, or both.In this invention, one or more particular portions of the glove, such as the tip of the index finger and thumb, are oversewn with a conductive thread. Various conductive threads are available commercially or are easily fabricated. A single metal wire can be used, such as copper (or an alloy thereof), gold, or silver, but such materials are relatively expensive and can abrade the surface of the touchscreen. A conventional thread can be painted with a conductive material, such as conductive silver paint, although sewing or knitting such can be problematic because of reduced flexibility of the fiber upon curing of the paint. Preferred is a conductive fiber or thread, such as a silver-plated nylon (for example, as commercially available from Less EMF, Inc., Albany, N.Y., as a 66 yarn 22+3ply 110 PET having a resistance of <1000 ?/10 cm). A conductive fiber or thread can be spun into a yarn suitable for use in a conventional knitting machine. The bulk of the glove is made of any yarn conventionally used or desired to be used that can be knitted into a glove. Such materials include wools, acrylics and modacrylics, cotton, cellulosics (including Rayon, Modal, and the like), nylon, aramids, elastane (Spandex, LYCRA, a registered trademark of Invista North America S.A.R.L. of Wichita, Kans.), and combinations thereof, including microfibers. A suitable yarn is 117/17 2-ply (50:50 acrylic:Modal). The bulk yarn and the conductive yarn are preferably the same gauge. Oversewing a conventional glove with a conductive thread is preferable to using an adhered or sewn patch. Adhesives are not typically both flexible and long lasting, and are typically not conductive, so only a portion of the patch will be adhered to the glove to leave the remainder free for contact with the glove and the users finger. Similarly, thread used to sew a patch will form a surface lying above (outermost from) the patch and will be subject to additional wear, so the sewing attachment of the patch may likely not last as long as the glove material as a whole.²   Conclusion In this paper,we have considered a problem of disability of using capacitive  touchscreens with gloves,and we have proposed a touch sense gloves with conductive materials which is can be used for cold weather.
