Since the time and frequency of people's daily use of mobile terminals will far exceed the past, this requires mobile terminals to meet ergonomic requirements, be suitable for long-term and high-frequency operations, have better human-computer interaction interfaces, more suitable viewing angles and More convenient operation.

At present, there are roughly the following types of input and control methods for mobile terminals in the market:

1. Twelve number/text keys + function keys: the most classic mobile terminal layout, and the type most widely accepted by consumers and has become the habit of the public. However, this method limits the size of the screen, or sacrifices the cramped manipulation caused by the size of the keyboard due to the expansion of the screen.

2. Qwerty full keyboard type: It is derived from the design of computer keyboards, and has been widely adopted by the popularity of smart phones. It is more popular in the North American market, such as PPC phones of Blackberry and HTC. It has a better text entry method and provides function button mapping that is beneficial to the smart machine transplanted to a PC, but it cannot realize one-handed control, and at the same time makes the terminal larger in size and complex in structure.

3. Touch screen type: Creatively integrate input and output on the same screen, which has a more intuitive human-computer interaction experience, but currently cannot realize single-handed operation of character input, which is easy to cause incorrect input and misoperation, and is easy to drop.

4. Mixed type: mix the above two control methods, just to meet the needs of different users.

To sum up, the problems of mobile terminals are as follows:

1. The size of the keyboard and the size of the screen restrict each other, which affects the interaction between the mobile terminal and the user;

2. Poor one-hand control;

3. Lack of special support for manipulation recognition at the operating system level to optimize user experience;

4. Ergonomic design considerations are not enough to support users who are prone to fatigue after long-term use.

Due to the limitations of existing mobile terminals, it cannot meet the requirements of the current and future network environment, communication environment and measurement and control environment, and is not suitable for long-term and high-frequency use by users. The improvement or redesign of the mobile terminal's control and interaction methods will play a vital role in whether the mobile terminal can better support mobile Internet and Internet of Things applications, and assist users in using the network and controlling other devices.
