Google announced on Wednesday that it is launching a new research application for Android phones that will allow anyone with a device to participate in medical research. < / P > < p > participants in the study will use the app to report any respiratory symptoms, measures they are taking to prevent the disease, and whether they have been tested for covid-19 or influenza. The app will collect demographic data such as age, gender and race. “Researchers in this study can examine trends to understand the link between mobility (such as the number of times a person goes out per day) and the spread of covid-19,” Google wrote in a press release. < / P > < p > the app will send data to researchers using a technology called federated learning, which will aggregate trends in batches from multiple devices instead of extracting information individually from each participant. < / P > < p > health research is Google’s response to the apple research app, which runs on IOS devices. Last year, it launched research on menstrual cycles, mobility and heart health, and hearing. Apple also allows researchers to build their own iPhone apps through its research kit program. < / P > < p > the research run through the application will have the same considerations as the research on other commercial wearable products: they can only recruit people who can buy products such as Android phones. Aggregating data is a good way to protect privacy, but it means that researchers cannot refine the information. The median income of Android phone users is lower than that of iPhone users, which may be a benefit of Google health research. (compared to the iPhone) Android may represent a more diverse set of data. We’re quite excited about the ability to take advantage of this, “John Brownstein, chief Innovation Officer at Boston Children’s hospital who worked with Google on the study, told stat news.
