I worked with a sociologist on a variety of projects which used sensors and cellphones to do computational social science. In the past, sociology was based on observing people, writing those observations down, and then thinking about them. Some statistics were gathered, but it was a very fuzzy science. Now, electronic devices and networks have made detailed big data about people available and sociologists are using it. Electronic surveys have replaced paper surveys and greatly increased scale. This happens mostly behind the scenes, such as research on the use of electronic medical records, marketing, employee motivation, etc. Take a look at her research projects here (and look up the people she worked with to see what else they are working on):

One of the things we did was build survey apps for phones which would sense activity and only pop up a question when a person wasn't doing much. The sensor data would also serve as a ground truth, telling us for example how much activity a person really did, versus how much they think they did. One early result from such research was that people think they are always doing things, rushing around, when the truth is they are sitting doing little for 95% to 99% of the day. We used the survey app to build a system to train a gait recognition machine learning algorithm for user authentication, where the survey app collected both sensor data and quick answers about what a person thought they were doing, where they were, were they walking, where they were... A lot of todays AI projects are essentially computational sociology, algorithms trained on peoples behavior that is used for predictions.
Business has bought up a lot of the sociology talent, to work with marketing, motivating employees, and changing peoples minds (somebody had to design those motivational posters in the hallways and some of them were based on sociology, lobbying campaigns to change public opinion are based on sociology, political campaigns use sociologists work).
I have a strong suspicion that all the Big Tech companies that collect lots of intimate data about people are employing sociologists to analyze that data and use it for many purposes, mostly related to advertising and motivating people to buy stuff, but also swaying opinion, making market decisions, investing, hiring and firing, and more. A common refrain in economics is that markets are unpredictable because you can't know what all the individual players are thinking, well now you can measure them and build models/AI. Big computational social science already exists at scale. I wonder what is being done with the health data from fitness trackers.
Similar things have been happening in economics. Unfortunately in both cases the data is being used mainly to gain special private knowledge about the social behavior of people, rather than informing the public or public policy. Because money. There are a few researchers who are more interested in the public good though.
