Description

One-hand operation method for a large-screen touch mobile phone

technical field

The invention relates to a mobile terminal device, in particular to a one-handed operation method for a large-screen touch mobile phone.

Background technique

At present, there are more and more mobile phones with large-size touch screens, and the screen size is getting larger and larger. There are already many large-size touch-screen mobile phones, which cannot be operated with one hand. In order to facilitate the user to operate the mobile phone with one hand as much as possible, the mobile phone manufacturers have used the following improvement measures:

First, place frequently used function icons at the bottom of the screen as much as possible.

Second, use gestures to achieve certain functional controls.

Third, try to use a screen below 4.5 inches, such as the very popular Apple 3.5-inch screen.

The above three improvements have obvious shortcomings, as follows:

The first improvement is impossible to put all the function icons in one screen at the bottom of the screen. First of all, the space is not enough. In fact, putting them all at the bottom will also increase the difficulty of touch and easily lead to accidental touch.

The second improvement is to use gestures. For one-handed gestures, the gestures must be simple and easy to operate. In this way, the functions that can be controlled are correspondingly reduced a lot, and it still cannot satisfy too much control.

The third measure is to reduce the size of the screen. Today, as larger screens become more and more popular, the market for small-screen mobile phones will become smaller and smaller. This measure cannot meet users' requirements for mobile phone screen entertainment and office work.

How to perform one-handed operation under the large screen and make the operation convenient becomes a problem to be solved in the present invention.
