AI Technical Summary

Problems solved by technology

[0007] In practical application, the above scheme has the following problems: not convenient, flexible and accurate

Specifically, the problem with the first mobile phone operation method is that the direction keypad occupies too much keyboard space. Generally speaking, the direction keypad occupies about one-third of the entire keyboard area; , mobile phone users must press the up and down keys, for example: when scrolling up and then down, you must first press the up key, and then press the key, it can be seen that this method is not very convenient to operate

[0008] The problem with the second mobile phone operation method is that because the cost of the above touch screen is higher than that of the general LCD, the total cost of this mobile phone is higher; convenient

[0009] The problem with the third mobile phone operation method is that it has poor touch, inconvenient operation and difficult to clean.

Specifically, the rocker is a columnar body with a small area at the top, and the contact area between the fingers and the rocker is small, resulting in a hand feeling when exerting a lot of force, and if the user's hand is wet due to sweating or other reasons, or the rocker It will be difficult to handle when it is tight

In addition, in addition to providing four directions of operation, the joystick generally does not provide operations in other directions. It can be seen that it is inconvenient in direction control and positioning.

Moreover, there is generally a narrow ring-shaped groove where the rocker and the mobile phone are combined, and it will be difficult to clean if dirt falls into it
