Abstract

The present invention is directed to a capacitive sheath fitted for a finger tip that includes conducting material, which may be placed over gloved hands. The capacitive sheath permits the user to operate a touch screen device without removal of any digit or hand covering apparatus, such as gloves.

Description

    TECHNICAL FIELD
  • This disclosure relates generally to coverings for fingertips that allow the user to operate capacitive touch screens on devices such as cell phones and media players without requiring removal of a hand covering.
  • BACKGROUND
  • New generation consumer devices increasingly rely on touch screen inputs such as virtual buttons and sliders displayed on the screen as an alternative to physical inputs and keyboards. For example the Apple iPhone® and Samsung Galaxy® are operated almost exclusively by manipulating virtual buttons, sliders, scrollers, and the like on a screen with the user's fingertips. Capacitive touch screen technology is largely displacing resistive touch screens due to industrial design, durability, and performance considerations. Generally, capacitive touch screens require “bare-handed” contact to sense a touch because the touch pad senses the fleshy fingertip, which, due to the conductivity of the flesh, perturbs the field of the screen. This gives rise to a problem when a user wears cold weather or protective gloves. Most devices using capacitive touch screens cannot be used while wearing gloves because the material of the glove is an electrical insulator that insulates the fingers and prevents the capacitive screen from detecting the conductivity of the fingertips through the gloves. The thickness of the glove material also limits the closeness of the finger to the screen and prevents the user from actually touching the screen.
  • One solution has been to provide a glove with the tip of the index finger sheath cut out so that a wearer's bare fingertip protrudes slightly from the end of the sheath. While this does allow the bare fingertip to be used with a capacitive touch screen, it is far from ideal because the fingertip is exposed to the elements and is not protected or kept warm. The opening in the glove also allows air circulation and moisture penetration, which often defeats the very purpose of wearing gloves. For protective gloves, such as electrician's gloves, breaches of the glove are simply unacceptable.
  • Another solution has been to provide gloves that include various electro-conductive features, such as finger tips that include metallic components (i.e. conductive caps) to allow the user to utilize electronic devices. These “touchscreen” gloves are typically expensive and limited in variety. Therefore, a user has to sacrifice style for functionality in order to use their electronic devices. Furthermore, gloves that include metallic components in the fingertips typically are limited in terms of surface area for the electro-conductive component. Accordingly, gloves of this type do not account for various finger sizes and shapes. These gloves are typically composed of relatively thin materials and not suitable for extreme outdoor conditions, such as skiing, snowboarding, or even motorcycle riding. In addition, this limited surface area of the conductive component fails to account for the dexterity of the user.
  • Another issue that exists in this area is the size of a user's fingers. Users with very large fingers find typing and using the touch screen input of these devices to be very challenging. Bulky gloves exacerbate this issue. Gloves with metallic components, such as those mentioned above, fail to appreciate this issue and make touch screen operation even more difficult for those users. Accordingly, a need exists for a component that allows users with larger fingers to easily utilize any touch screen device.
  • A need exists for a solution that allows the user to utilize any store bought glove, retain all of its insulating and protective attributes, but allows the wearer to operate the capacitive touch screen of an electronic device. The present invention provides an independent, fully-transferrable sheath that works in conjunction with a glove and/or hand to interact with a touchscreen or touch pad device. Furthermore, a need exists for an independent, fully-transferrable sheath that includes a disc with a nub that allows users with larger fingers to operate a touchscreen or touch pad device.
  • SUMMARY
  • Briefly described, the present invention, in an embodiment thereof, comprises a sheath that allows a user to interact with the capacitive touch screen of a device without removing a hand covering or glove and exposing the user's hands and fingertips to the elements. The sheath comprises at least a piece of fabric configured to cover the user's fingertips and finger receptacle of the user's hand covering. At least a portion of the sheath includes conductive material. When a capacitive touch screen is touched with the sheath, the conductive material perturbs the field of the screen similar to the conductive skin of a bare finger and thus emulates a touch with a bare finger. As a result, the virtual buttons and other elements of the screen can be activated while wearing or utilizing the sheath of the present disclosure.
  • In some embodiments, a capacitive sheath is provided that includes a first portion having a first edge, where the first portion includes a conducting material, and a second portion having a second edge, where the second portion includes a flexible material, where the first edge of the first portion is coupled with the second edge of the second portion and the capacitive sheath is adapted to fit over a hand covering of a user.
  • In other embodiments, a capacitive sheath is provided that includes a conductive material, where the capacitive sheath is adapted to be insertable over a portion of a hand covering of a user of a capacitive touch screen.
  • In other embodiments, a method for operating a touch screen electronic device with a gloved hand is provided that includes the steps of: applying a capacitive sheath to a finger receptacle of the hand covering of a user, where the capacitive sheath includes a conducting material.
  • These and other objects, features, and advantages of the sheath of this disclosure will be better understood upon review of the detailed description set forth below when taken in conjunction with the accompanying drawing figures, which are briefly described as follows.
