     FIELD OF THE INVENTION 
       [0002]    The current invention relates to an accessory device that prevents writing fatigues and helps people, especially children, to hold a pen or pencil correctly while writing. In particular, the current invention relates to a pen/pencil grip that may be attached to a pen or pencil, enabling the user to grip the pen/pencil in a correct manner. In addition, the current invention also covers embodiments that include not only the grip, but also the Pen/Pencil being used. 
       BACKGROUND OF THE INVENTION 
       [0003]    Even in an age of computers and printers, writing with a pen or pencil has persisted as an essential part of many people&#39;s lives. In many cases, users grip pens and pencils directly by the shafts to write. However, it is easy to get tired and uncomfortable at his/her finger tips and other points held flush against the shaft. Moreover, when children are learning to write, it is important to teach them how to grip the pen/pencil in a proper manner and maintain a healthy posture. Thus, it is desirable to provide accessory devices that offer guidance to people regarding the best way to hold a pen/pencil. Some devices have been developed for such purposes. 
       DESCRIPTION OF RELATED ART 
       [0004]    U.S. Pat. No. 7,014,379 discloses a pen holding auxiliary device that not only provides comfortable touches but also the distance between the sleeves is adjustable to fit users&#39; hands of different sizes. The device mainly comprises a front sleeve, a back sleeve and a length adjustable element. The front sleeve slidably embraces a shaft of the pen for being placed between finger tips. The back sleeve slidably embraces the shaft of the pen for being placed against a part of the hand between a thumb and an index finger thereof. The length adjustable element surrounds the shaft of the pen and connects the front sleeve with one end and connects the back sleeve with the other end. 
         [0005]    U.S. Pat. No. 8,152,396 discloses a writing instrument grip apparatus for holding a writing instrument for performing writing, the apparatus includes a first member adapted to receive a user&#39;s thumb and index and side of middle fingers and having a substantially vertical cylindrical chamber for receiving the writing instrument adapted to extend past a bottom surface of the first member for contacting a surface for performing writing; and a second member adapted to receive a user&#39;s middle, ring, and small fingers coupled to a top of the first member so that motion of the hand of the user powers the writing instrument for performing the writing in response to the motion; wherein pressure is directed away from joints of the thumb and at least one finger of the hand of the user. 
         [0006]    These disclosures, however, are not as complete and easy to use as the current invention, which provides finger placement positions, as well as additional grooves and bulges that compliment other parts of a hand. The current invention is a more advantageous solution compared with the other teachings. 
         [0007]    In summary, various devices are known in the art, but they are distinctively different from the current invention. Moreover, the other inventions fail to address the issues solved by the invention described herein. One embodiment of this invention is illustrated in the accompanying drawings and will be described in more detail herein below. 
       SUMMARY OF THE INVENTION

As indicated above, the left hand implement for the current invention may be a mirror image of the right hand implement or alternative there may be small differences between the two implements. For example, the pen/pencil tip  105  may protrude further from the pen/pencil grip  10  for left handed implement than the right handed implement due to the nature of how left handed people must write to avoiding wiping the written words with their hand. 
         [0053]    As indicated above, the current invention may also incorporate accessory structures to improve the results for better gripping postures. For example, the pen/pencil grip may include indicators such as LED lights, bulbs, mini-screens, buzzers, heating elements or any other accessories that may be used to display text, images, patterns, light, emit sound, or provide any other kinds of signal. The indicators may be positioned anywhere, but are preferably attached to the pen/pencil grip as places that are visible when the pen/pencil grip is in use. E.g. between the thumb placement recess and the index finger placement recess on top of the head section. Underneath the finger locations, such as but not limited to the thumb placement recess and the index finger placement recess, there may also be electrical switches, such as but not limited to mechanical, capacitive, resistive, or light sensitive switches, so that correctly or incorrectly positioned fingers may be detected. Such detections may trigger or alter the display or emission of the indicators, e.g., making the LED flash, serving as a sign for correct or incorrect gripping of the pen/pencil. To allow the indicator/switch accessories function properly, the pen/pencil grip may also include a power source, such as a battery. 
         [0054]    The current invention covers not only the embodiments that include only the pen/pencil grip, but also embodiments comprising the pen/pencil grip combined with a pen/pencil, forming a writing apparatus. The connection between the pen/pencil and the grip may be removable—detachment does not cause physical damage to the components—or permanent—detachment causes physical damage to the components. 
         [0055]    The size of the pen/pencil grip may vary to fit different kinds of writing implements and different hand sizes. The overall length measure from the head section frontal end  25  to the end of the tail section  60  is preferably between about 10 mm to about 100 mm. It is also preferably that the pen/pencil grip is small and easily portable. 
         [0056]    The pen/pencil grip may be made from any material. While it is preferable that the different sections are made from the same materials, such is not a strict requirement. The pen/pencil grip may be made from materials such as but not limited to: metals such as gold, silver, platinum, titanium, and alloy, glass or fiberglass, rubber, composite materials, and plastic such as, but not limited to, polyethylene terephthalate (PET), high-density polyethylene, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polystyrene (PS), high impact polystyrene (HIPS) and polycarbonate (PC), or some combination thereof. It is preferred that the material is robust and durable. 
         [0057]    In another embodiment of the present invention, the invention is equipped with a plurality of switches. These switches may be mounted on the surface of the present invention, or they may be disposed closer to the interior of the device. Preferably, the decision of where to place to switches will depend on the type of switch being used. For example, mechanical switches will preferably be mounted on the outer surface of the device so a user may easily activate the switch with the press of a user&#39;s finger. The present invention may also incorporate capacitive switches which can be located in any area of the device where they can detect a user&#39;s electrical field, as they do not need to be mechanically actuated. In a preferred embodiment, the capacitive switches are configured to detect when a human digit is placed on the device. More preferably, these capacitive switches are configured to detect when a human is holding the device in the proper configuration. Preferably this proper configuration results in a user gripping the present invention with a standard “tripod” grip. Preferably, these switches can be made as inputs to analog or digital circuitry held within the body of the present invention. These inputs can be translated into appropriate outputs through changes in voltage or current. Further, the present invention can be equipped with at least one microcontroller which has been programmed in a certain fashion as to response to specific selected inputs. An array of switches, for example, could be depressed by the user resulting in a digital pattern sequence to be created by the microcontroller in response. In a highly preferred embodiment, the capacitive switches of the present invention are electronically connected to at least one light source that indicated to a user when the proper grip configuration has been used. 
         [0058]    In embodiments where microcontrollers are used, the response of the microcontroller can be interpreted by a computer or other electronic device via a wireless connection. This wireless connection can be transmitted at a number of different frequencies including Wi-Fi® and Bluetooth®. This data may also be transferred via a wired connection. 
         [0059]    In addition to the at least one light source, other embodiments exist where the present invention is equipped with motors capable of generating haptic feedback when a user has begun holding the device in the appropriate manner. These motors could readily be populated within and inner compartment designed for this exact purpose. 
         [0060]    Some embodiments exist where olfactory stimulation is caused when the device is gripped in the proper position. In these embodiments, the present invention is equipped with a small pouch or pocket that is embedded into the body of the present invention. Preferably this pouch will use a wick to absorb fragrances. Depending upon the input from the user through activation of the switches, the microcontroller within the device can be programmed to heat or otherwise open the vessel by which the fragrance is released. 
         [0061]    A microphone and speaker can easily be embedded in the device that could allow the user to speak to the device and hear responses from the device according to the programming of the microcontroller stored within. In a preferred embodiment, the present invention is equipped with battery-powered microprocessors to act as both an input and output device in order to convert user inputs in the form of speech or touch, into outputs that are mechanical in nature (vibration), audible in nature, visual in nature (turning on an LED, for instance), olfactory in nature (emitting a scent from the device), or any other bi-directional mechanism to convey the physical location, speed, and acceleration. 
         [0062]    As another example, a GPS receiver could be installed into the device in order to locate the device&#39;s position anywhere on the globe in 3-dimensional Cartesian space. 
         [0063]    One might use this as not only a writing instrument, but for the purposes of tracking the individual possessing the device, or possibly locating the device if the user discovers it is missing. 
         [0064]    Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
