Summarize the shortcomings and shortcomings of the current design of unmanned vending machines

Summarize the shortcomings and shortcomings of the current design of unmanned vending machines, and the ideal goal of the collation and commonality design of the Guangdong unmanned vending machine user group is to meet the needs of all people to achieve a society full of fairness and care, but under normal conditions Down, it is very difficult to do, it is just an ideal and the direction of hard work. In fact, no product can satisfy all users, because there are some people with severe physical disabilities, sensory disabilities, and cognitive disabilities who cannot use certain products, including vending machines. It can be seen from the shared design pyramid that people with severe dysfunction need special facilities or special designs to help them. The common design is to expand the user population of the product, not a special design specifically for a vulnerable group. The focus of shared design considerations is groups that have certain behavioral capabilities and have common intersections with the general population. In the common design of vending machines, the general population, the visually impaired, the hearing impaired, the upper-limb disabled, the lower-limb disabled, the elderly, women, children and other groups can be considered. The general population usually refers to healthy people who do not need special care when using a product. The formal definition of health is: health refers to a condition in which all three aspects of physical, psychological and social adaptation are good. Relatively speaking, healthy people are physically sound, and can recognize and respond to external colors, text, graphics, and sounds in a timely and accurate manner. But health is a developing concept. In some special circumstances, certain healthy people will also become vulnerable groups. For example, if a person with normal vision can't read the words in a book in dimly lit conditions, he is equivalent to a person with visual impairment. If a person is carrying something in his hand, he can only perform a certain operation with one hand, which is similar to a person with upper limb disabilities. In a noisy workshop, even people with normal hearing will not be able to hear others. This is the case of the hearing impaired. Therefore, only when the requirements are met in all aspects can people show healthy behavior. In fact, there are not many people who are completely blind in life. Most visually impaired people only have defects in certain visual functions. Some people with color blindness and color weakness have difficulty in recognizing or distinguishing colors; people with high myopia can distinguish colors, but they cannot see small texts; and some people have difficulty adapting to changes in light and shade. The characteristics of different obstacles can be integrated in the design A variety of information guidance methods, such as voice prompts, low-frequency flashing lights, special touch and other forms. Using multiple senses to help the visually impaired obtain information is an important means to improve the commonality of vending machines. I hope that the above content introduced by the Guangdong vending machine is helpful to everyone. If you want to know more information, please continue to wait for the author to share it.
