Background technique

In order to meet the needs of modern people who emphasize efficiency in everything and use one machine for multiple purposes, more and more functions that could only be realized on personal computers in the past are gradually integrated into the design of mobile phones. In addition to the traditional functions of making phone calls, the new generation of mobile phones also has the functions of playing multimedia files, browsing the Internet, sending and receiving e-mails, managing personal data and itinerary, and even simple document processing functions. However, as the functions become more and more powerful, the types and numbers of buttons that need to be matched also increase. At this time, in order to take into account the space of the screen and the keyboard at the same time, many mobile phone manufacturers are gradually inclined to the design of the slider shape in the concept design of the mobile phone.

FIG. 1A is a schematic diagram of the appearance of a known slide phone. Before the user pushes the slide cover away, the keyboard is hidden under the fuselage. As shown in FIG. 1B , when the user pushes the slide cover, the keyboard will slide out from the side of the mobile phone for the user to input. According to the configuration direction of the keyboard keys, when the user slides out the keyboard from the side of the mobile phone, most of them will habitually rotate the mobile phone 90 degrees to operate. In order to make the user feel more convenient when using the mobile phone, mobile phone manufacturers When implementing the internal software of the mobile phone, the direction and content of the display screen will also be changed according to the current state of the mobile phone. Please refer to FIG. 1A and FIG. 1B at the same time. Comparing the screens displayed on the screen 110 and the screen 120, it can be found that when the user slides out the keyboard and rotates the mobile phone 90 degrees to the right, the screen of the mobile phone will also change from the vertical orientation in FIG. 1A The display turns to the landscape display in Fig. 1B. In this way, the user can watch the horizontally displayed screen while operating the keyboard, without worrying about the inconsistency between the display screen and the keyboard, and can conveniently select the application content to be operated.

However, no matter in the vertically or horizontally displayed screen, the user must enter the function menu by clicking layer by layer, and then select the application program to be executed from the function menu. Such an operation mode is inconvenient for the user. For example, when a user wants to use a mobile phone with a built-in window operating system to send e-mails, he must first slide the keyboard to enter text, and then he must start from the "Start" menu on the standby screen of the mobile phone. Find out where the email application is located to launch the application. In this way, a lot of time is bound to be consumed, and it is also easy to generate a relatively negative perception of use for the user.
