What is a Virtual Keyboard?

The virtual keyboard is ^[1] a virtual keyboard similar in size to a small mobile phone, allowing users to type articles or e-mails as easily as using an ordinary keyboard.

Virtual keyboard pass

Breakthrough direction 1: keyboard display contention, visual transparency concept is easy to solve. On our touch screens, we often encounter the problem that the virtual keyboard area is too large, which leads to too much background coverage and affects our operation visibility. So what is the fundamental way to solve this problem? At present, we have used the technology of keyboard transparency, which can solve the conflict between the keyboard and the background interface visually, and release the interaction space, so that we do not have to worry about the area of the touch screen will affect our interface background.

We all know that the see-through keyboard is not a new technology, and especially for professionals, there is no technical difficulty. But this does not mean that we can use this technology freely. The transparent keyboard technology solutions we can see now are directly superimposed transparent keyboards on the background. Although it solves the original problem, it also leads to new colors and collocations when we use it, and poor visual comfort. The problem makes people look inconvenient. Therefore, the transparent keyboard is really acceptable. First, we must meet our requirements for a beautiful background picture, minimize the impact of the keyboard interface on the background picture, and preserve the background picture information to the greatest extent; second, continue to improve the humanized integration of the transparent keyboard, and the keyframe ghosts that are displayed redundantly It must be removed, and the key characters can also be concealed by hollowing out, increasing or decreasing the brightness or intermittent display.

Breakthrough direction two: To solve the problem of narrow and dense key grids, only layout layout is required.

The keyboard is limited by the screen size, and its use area is limited, which causes the position of each character of the keyboard to be dense, and when the touch screen is touched by hand, the position of each symbol of the keyboard cannot be felt by fingers like the physical keyboard. It was difficult for us to find characters ... this is a problem that has always existed on the touch screen phones and tablets we use. If it is difficult to accurately click the most basic characters, let alone blind typing. To change these problems, we must increase the keyboard area and expand its layout. At the same time, based on the transparency of the keyboard, we can easily implement the full-screen layout of the keyboard, allowing us to have a large and comfortable key grid layout.

The full screen keyboard can make full use of the corner positioning of the touch screen. When we click on the touch screen with our hands, although there is no touch of the physical keyboard, we can determine the position of each symbol of the keyboard by touching the corners of the screen with our fingers. As you can see in the picture, the key grid like the turtle's back, its outer key grid can achieve corner positioning, and the area of the keyboard can be appropriately reduced, and the key grid in the center area is very large. Key grid positioning is also easy and accurate. Therefore, it is very easy to realize the 100% blind hitting of the turtleback layout.

In order to make better use of touch screen positioning and enhance the accuracy of the keys, it is also a more appropriate solution to design a series of bumps in the area around the touch screen.

The use of a full-screen large-keyboard keyboard is convenient but it has operational requirements. If our users do not have a good grasp of the keypad layout, then such operations will only make users feel more trouble and headache, let alone Easy operation.

In general, the full screen of the virtual keyboard is actually very easy to implement, and it can be obtained on current hardware devices.

To a very good application, so we can conclude that full-screen virtual keyboard is a good direction for keyboard development.

Breakthrough direction three: Frequent operation of interface switching to solve three-dimensional

The key grid increases, the interface increases, and the user's interface switching actions will increase. In this case, in the future, we will simply enter a simple text such as "Go home and eat", and there will be a troublesome situation of "switch operation keystroke input switch operation keystroke input". The switching action is so cumbersome that it makes our input process very painful, which not only affects our speed, but also makes us ordinary consumers feel that touch screen has become a technical task.

However, if we do not use a single operating platform, but use two independent operating platforms, the technology can achieve two operations at the same time. From a professional point of view, assigning the switching operation and keystroke operation of the interface to the two input platforms respectively can realize the synchronization and parallelization of the switching and keystroke input, so that we can complete the two tasks in one second.

To put it simply, the three-dimensional operation is to migrate some touch screen operations of the virtual keyboard to an input platform other than the touch screen, and simultaneously complete the input process through the touch screen and an external input platform. Just like eating, pigs can only eat with their mouths, how low-powered and crude, and we humans eat with our hands more relaxed and elegant. This is also the case during the input process. The switching action is transferred to another input platform other than the touch screen. The touch screen is only responsible for keystroke input. The two platforms work together to achieve the completion of the switching operation and the keystroke input.

As we see in the animation below, the acceleration sensor is used to help our touch screen input. The acceleration sensor is only responsible for interface switching and the touch screen is responsible for keystroke input. We can close the eyes and shake the phone while using our fingers to perform keystroke input. .
