Based on the observation and communication with the visually impaired baristas during the coffee making process, the extracted needs were categorized into three levels: core needs, secondary needs and other needs. Core needs are the necessary steps in the production project; secondary needs are those that affect the quality of the final production; and other needs are those that do not have a significant impact on the final coffee production and can be ignored. Through behavioral observation as well as user interviews, the behavior of visually impaired people is combined with pain points to summarize the analysis of the general needs of visually impaired baristas, and the needs are transformed into three levels: core needs, secondary needs, and other needs. Table 4 Summary of the Need Level. Need Level Need Content Core needs Product differentiation indicators Magnification of important product information Determining the product's location Product safety in use Secondary needs Tools for controlling liquids Tools for controlling coffee beans Simplicity of product usage Other needs Simplicity of the operation interface Ease of cleaning Source: Made by the author (2025) Through research and analysis of schools for the blind and visually impaired coffee shops in China and Thailand, the author identified three primary needs of visually impaired individuals when using coffee-making tools: differentiation, positioning, and control. a) Differentiation requirements The differentiation requirements primarily focus on identifying the raw materials for making coffee and recognizing the equipment and tools. - When baristas need to differentiate between different types of coffee beans, a lack of distinct tactile or auditory differences or clear labeling can lead to using the wrong beans. - When visually impaired baristas need to make different types of coffee, they often need to use different machines which are similar in appearance and size but have different functions, which may easily lead to confusion. If the visually impaired barista cannot distinguish the equipment accurately, the visually impaired baristas may use the wrong function or machine. - The process of coffee making for the visually impaired involves coffee selection, grinding and extraction. They often rely on their sense of touch and smell. Since they cannot visually identify the tools, they will repeatedly identify them, which is time-consuming and laborious. - 103 -
