| TECH& LIFE MEMORY HELPER A talented young team from Ireland, the creators of Memory Helper, developed this support app (应用软件) for people with dementia (痴呆). And they won the final at the 2020 competition, standing out among 5,400 students from 62 countries, Mars Times reported. Last year, Laura, Aaron and Vicky put their heads together for Technovation Kids(TK), an international competition that encourages teenagers to create an app that solves a community problem. The inspiration for their project came from their teacher's mother, who had dementia and died earlier this year. To complete their project, the three designed an app to support both people with dementia and their caregivers. The app solves some common problems connected with dementia like loss(失去) of memory. “We hope that our app can reach millions of people who have dementia and just make their lives kind of easier, ” Laura said. |  |
