Key Button Separator on Virtual Keyboard

The present invention relates to a key button separator of a virtual keyboard, and more particularly, stable key buttons by providing an environment similar to a real keyboard in a system using a virtual keyboard through its own display device. The present invention relates to a key button separator of a virtual keyboard for improving the convenience of use by allowing a user to touch it.

Recently, in a system using an input device through its own display device, such as a tablet computer, a user can perform input by touching a virtual keyboard with a finger. In general, the touch method uses a pressure-sensitive or capacitive technology. In particular, the capacitive technology is applied to expensive tablet computers such as an iPad and Galaxy Tab because of its high recognition rate and multi-touch. It is true.

On the other hand, the virtual keyboard as described above is a key button is formed as an image on the display screen, it is possible to input the corresponding key by recognizing the portion where the image is formed to touch accurately. However, in this case, due to the characteristics of the flat display screen, a special boundary or means for tactilely distinguishing each key button is not provided, thereby causing an input error, that is, a typo.

The present invention is to solve the problems caused by the virtual keyboard as described above, to provide a similar environment to the actual keyboard by distinguishing each of the key buttons in a tactile sense, a key button separator that can improve the ease of use The purpose is to propose.

The present invention provides a pad-type key button separator that forms a hole through which a fingertip can pass at the same position as the key buttons of the virtual keyboard, and when the key button separator is placed on the virtual keyboard, the key button is used. The above object is achieved by naturally forming a boundary between the two and visually tactilely distinguishing them.

According to the invention,

It can be easily carried and placed on the virtual keyboard whenever needed, giving the impression of using a virtual keyboard as if using a virtual keyboard.The boundary between the key buttons is formed so that the accurate touch can be clearly distinguished visually or tactilely. As a result, it is possible to reduce a typo and to obtain a key button separator that greatly improves ease of use. In particular, it is possible to apply a capacitive technology that can be recognized only when a human finger is directly touched by a virtual keyboard. have.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 9.

1 is a plan view of a key button separator according to the present invention, Figure 2 is an exemplary view showing a state using the key button separator according to the present invention on a virtual keyboard, Figure 3 is a key button separator according to the present invention Figures 4, 5, and 6 are examples of a state separated from the virtual keyboard. Figs. 4, 5, and 6 are exemplary views showing various examples of forming a touch ball in the key button separator according to the present invention. 8 is an exemplary view showing a key button separator having a fixing band formed on a pad according to the present invention, and FIG. 9 is an exemplary view showing a key button separator having a fitting groove formed on a pad according to the present invention.

As shown, the key button separator of the virtual keyboard according to the present invention is formed in a plate shape, and includes a pad 100 having a touch hole 120 corresponding to a key button position of the virtual keyboard.

The pad 100 may be formed of various materials. However, when the pad 100 is placed on a virtual keyboard, the pad 100 may be formed of a material such as synthetic rubber or silicone, which is relatively easy to mold while allowing stable use. Do.

The touch hole 120 formed in the pad 100 is formed by punching the pad 100 so that the key button can be touched with a fingertip while the virtual keyboard is covered with the pad 100. In this case, as shown in FIGS. 1, 2, and 3, the touch hole 120 may be formed as it is in the form of key buttons in the virtual keyboard. In this configuration, the pad 100 has the same shape as the virtual keyboard. Will be shown.

When configured as described above, a boundary is naturally formed between the touch balls 120 to visually or tactilely distinguish each key button while allowing the key buttons to be touched and typed.

Here, the touch hole 120 as described above is formed one by one for each key button or a key button that is not frequently used, for example, a function key (Function Key) in the Qwerty array keyboard, a plurality of one It can be formed by a method such as to form a long left and right so as to be disposed in the touch hole 120.

Of the touch holes 120 according to the present invention described above, when using both hands in the QWERTY array keyboard, the keyboard is tactile at the edges of the touch hole 120 formed on the 'f' and 'j' key buttons pressed by the index finger. It can be formed to form a division mark (122) to be divided into.

The division mark 122 may be formed by a method of forming a small protrusion or groove, through which the position of the key button can be easily grasped by the touch of the index finger without looking directly into the eye. Only one such division mark 122 may be formed around the touch hole 120, and a plurality of division marks 122 may be formed as necessary.

Meanwhile, as illustrated in FIGS. 4, 5, and 6, the touch hole 120 may be formed in the partition frame 110 partitioned to have a predetermined space. That is, the partition frame 110 is formed in the form of each key button as if the virtual keyboard is drawn on the pad 100 as it is, and the touch hole 120 is formed by drilling a hole in the partition frame 110. will be.

When formed as described above, while the partition frame 110 gives a visual feel like the actual keyboard, a touch hole 120 is formed in the pad 100 and a clear boundary is formed between each key button by the remaining part. In addition, each key button can be touched while being touched.

Here, the partition frame 110 may be formed for every key button formed on the virtual keyboard, but may be formed only on some key buttons or to accommodate several key buttons at once as needed.

For example, frequently used number and letter key buttons form a partition frame 110 for each key button, whereas function keys are not frequently used, such as F1 to F4, F5 to F8, and F9 to F12. The four will be divided into a group to form a partition frame (110). The partition frame 110 may be modified in various ways in consideration of the position and use frequency of the key button.

A preferred example of forming the partition frame 110 is to have the same appearance as the virtual keyboard. That is, the partition frame 1100 is formed in a form in which the virtual keyboard is drawn as it is, thereby visually giving the impression of looking at the actual keyboard.

Some of the touch holes 120 may be configured to be formed at a position biased to one side within the partition frame 110. For example, a QWERTY keyboard is used to form a touch hole 120 in the center of the partition frame 110 in the upper row of key buttons, and in the lower row of key buttons, the touch hole is biased downwardly in the partition frame 110. 120 can be formed. When formed as described above, a space in which a finger can be placed between the top row touch ball 120 and the center row touch ball 120 is secured, and the finger can be placed in a waiting state without typing.

As described above, the configuration in which the touch hole 120 is biased in the partition frame 110 is formed in the middle row of the touch hole 120 at the upper part in the partition frame 110 and the touch key 120 is in the lower row key button. The same space can be ensured even if the center) is formed in the center of the partition frame 110, and is selected as needed. In addition, it is also possible to form only the key button in which the four fingers are positioned from the index finger to the little finger in the partition frame 110 without forming the position of all the key buttons in the middle row.

Alternatively, the touch ball may be configured by varying the size according to the position of the key button. In the case of the QWERTY layout keyboard, the key buttons corresponding to S, D, F, J, K, and L among the middle row key buttons are often placed on the user's finger while preparing for typing. Since the manipulation of the key button is precisely made, it is possible to make the finger to be placed when preparing for typing by maximizing the space where the touch ball is not formed by making the size of the touch ball relatively smaller than other key buttons.

As illustrated in FIG. 7, the touch hole 120 may be formed to be inclined toward the inside of the wall from the top to the bottom thereof. As the pad 100 is formed to have a certain thickness, the jaw is formed as much as the thickness of the main pad 100 by drilling the touch hole 120. Therefore, a finger may be caught at the edge of the touch hole 120 when typing, thereby preventing a quick touch.

Thus, by forming the wall of the touch hole 120 to be inclined as described above to minimize the phenomenon that the fingers are caught to configure the key button can be touched stably. At this time, the inclination of the wall surface of the touch hole 120 may be preferably inclined while forming a gentle curve.

Key button separator according to the present invention implemented through the above configuration by forming a fixed band 200 on the pad 100, as shown in Figure 8 pad 100 to the device using a virtual keyboard It can be configured to be firmly fixed.

The fixing band 200 may be formed integrally with the pad 100 by the same material as the pad 100, or may be separately provided and connected to the pad 100. At this time, the fixing band 200 is preferably formed of a material that can be stretched to some extent, it may be able to be used stably by holding the device more firmly.

Then, as shown in FIG. 9, the pad 100 may be formed by forming edge fitting portions 130 having grooves formed inwardly so that both edges of a device using a virtual keyboard are fitted at both bottom edges of the pad 100. It can also be configured to be fixed. When the corner fitting portion 130 is formed of the same material as the pad 100, the pad 100 is fixed by grasping both edges of a device in which a virtual keyboard is used elastically.

As described above, the key button separator according to the present invention can be applied to any device as long as the device uses a virtual keyboard, and the internationally standardized QWERTY arrangement is only required to form the touch ball 120 according to the arrangement of the key buttons. In addition to the keyboard, it can be applied to various arrangements.
