For example, the popularity of smartphones today is very high, from the elderly to teenagers, from the city to the countryside, people are immersed in the virtual network formed by intelligent terminals.

Although smart handheld terminals bring a lot of convenience to people's lives, for example, shortening the distance between people and improving communication efficiency; however, many problems have arisen, such as "mobile phone family". In general, if the user of the handheld terminal is at home or does not affect the environment of others, even if the terminal is excessively focused on, in addition to causing harm to the user's body, there is generally no other hazard. However, if the user is the driver, if the driver's focus is on the handheld terminal or the handheld terminal is used to control the steering wheel with one hand, the probability of a traffic accident is greatly increased, which not only affects the safety of the driver's life and property, It is likely to cause serious personal or property damage to others. At present, although the Traffic Management Law stipulates: “Any motor vehicle driver must not use a mobile phone, smoking, etc. to leave the steering wheel with one hand while driving,” the actual driver’s use of the mobile phone during driving is not uncommon, resulting in traffic accidents.
