"How can I save this person's phone?" "Where should I press this video?" My grandpa output the problems that have been saved for half a year like bullets, because the end of the year is coming, "Mengqi is back". After the summer vacation in 2022, Ni Mengqi became a freshman in a university in Fujian. Before college, Ni Mengqi was the "intelligent product assistant" of her grandparents. What functions of mobile phones and tablet computers were uncertain, and Mengqi immediately stepped out. After leaving home for college, Ni Mengqi's remote "command" was inconvenient, but the next day after returning home from vacation, the "intelligent product assistant" resumed work. "Although my sister in junior high school also uses her mobile phone very smoothly, her grandparents always think that she is still a child and still needs to wait for me to come back," Ni Mengqi said. Li Xinmiao, who studied at Luliang University, did not expect that one day she would "exchange roles" with her grandmother. Since kindergarten, she has grown up under the protection of her grandmother. After the emergence of smart phones, the former child has become the "little teacher" of her grandmother. In her view, teaching grandma to use smart phones has brought back the intimate relationship that has "gone far" because of geographical distance. With the rapid development of emerging technologies, a "digital gap" is between some middle-aged and elderly people and digital life, leaving them at a loss. However, as "Internet aborigines" grow up, they gradually become "little teachers" of their elders, and "digital feedback" has also become one of the key words in their communication with their elders. China Youth Daily · China Youth University Media launched a questionnaire survey for college students across the country. A total of 3035 valid questionnaires filled out by students from 142 colleges and universities were collected. 95.19% of the respondents taught their parents, grandparents or other elders to use electronic products, of which 91.86% would teach their elders when they returned home or went home during the New Year holiday, and remote voice or video guidance (33.81%) and remote screenshots and guidance maps (20.89%) also occurred from time to time. The position of embracing digital life with the elders as the "chief intelligent product assistant" is unshakable, which stems from Ni Mengqi's tireless efforts to answer questions. Grandma in her 60s began to learn to use WeChat a few years ago, from how to send voice, how to make video calls, how to send friends, and how to praise others. She always asked Ni Mengqi if she wanted to learn. Grandma is also catching up with the trend of electronic products. She also wants to have a try when she sees videos sent by others. Under the guidance of her granddaughter, she learned to take videos, send daily life and beautiful scenery to App, and then share them with her friends. Ni Mengqi also taught Grandma how to use the tablet computer. "There are not many entertainment items for the elderly. Grandma likes watching TV dramas. Because the on-demand function of TV is too complex, the mobile screen is too small, and watching video is too tiring, I taught Grandma the function of using tablet computer to brush dramas." In Ni Mengqi's view, smart electronic products are really convenient to use, and should let the elderly enjoy the convenience and new functions they bring. According to the survey of young and middle-aged school media, smart phones (94.76%) are the most used by respondents to teach their elders. In addition, computers (30.51%), smart TV (28.20%), tablet computers (20.13%), cameras or video cameras (8.11%)
