Open the mobile app and the system will automatically read the screen: which text is on the page, which window is open, which program is running, etc., and provide voice prompts one by one. Reading news, relying on text recognition technology to "read" information; If you want to shop, picture to voice "depict" product details... With the help of information accessibility technology, many visually impaired people can freely use internet products in their work and life. The internet has integrated into every aspect of people's lives. Eliminating the "digital divide" and helping more people embrace the vast world is the essence of the development of the internet. At present, over 32000 government websites in China have achieved information accessibility. Mobile applications such as transportation, shopping, and entertainment allow visually impaired people to better connect to the world with just one phone. Whether reading or traveling, with the navigation of "Internet tactile paving", the life of the visually impaired will be more abundant, the channels to integrate into the society will be more unblocked, and the realization of self-reliance will be more reliable. It should also be noted that as more and more production and life service information is gathered on the internet, especially on mobile applications, it becomes more urgent to do a good job in information accessibility. Currently, visually impaired individuals still have some obstacles to accessing the internet that need to be eliminated. For example, in some audio applications, the playback button is just an icon, and the software can only rigidly say the word "button" when reading the screen, unable to express its specific meaning, which is not conducive to visually impaired people receiving information. Some software upgrades are frequent, and developers have added richer features and designed more aesthetically pleasing interfaces, but accessibility requirements often fail to keep up in a timely manner, resulting in new inconveniences. This indicates that there is still considerable room for improvement in information accessibility construction. To unblock the "network tactile paving", it is necessary to build the foundation of the initial design. The information accessibility optimization of internet applications is basically where there are checkpoints to clear up, and only a few can sink to the initial design. Some developers do not realize or understand how to optimize the internet access needs of visually impaired individuals. When designing internet products initially, the requirement of information accessibility should be considered. Relevant departments may consider introducing unified standards to provide guidance for improving the initial design of applications. The unblocking of the "network tactile paving" depends on the construction of the industry ecology of synergy. For example, some smartphone manufacturers have developed accessible tactile designs that allow visually impaired individuals to touch interface elements, making it easier for them to quickly perceive different controls. Some leading hardware companies have conducted in-depth optimization of mobile phone systems for accessibility, providing a demonstration for the industry. We should further enhance the enthusiasm of all parties to participate in the construction of information accessibility, timely summarize replicable and promotable experiences and practices, and encourage the launch of more information accessibility products and services. At the same time, promote the open sharing of relevant technologies, help third-party platforms upgrade without barriers, and form a joint force to promote information accessibility construction. The smooth "network tactile paving" can not be separated from the contribution of information accessible professionals. Visually impaired individuals have their own ways of thinking and usage habits. Without receiving specialized training, it is difficult for programmers to understand the needs of visually impaired individuals and optimize their products. Currently, there is a shortage of relevant professional talents in China, and it is necessary to promote more engineers to effectively integrate barrier free design into future product development through training and exchange.
