ACTION_SPEED

Action time (a.k.a. Proxy CRT) refers to the amount of time it takes for you to decide and complete a task on your smartphone.

Action time is the time it typically takes you to execute simple actions, such as inputting text characters, browsing or navigating between apps. The speed and efficiency with which you are able to perform these actions will impact your action time. Action time can be influenced by a variety of factors, including individual ability, distraction, and environmental factors.

Tracking your action time and typing speed can help you monitor your health. Slow action time or typing speed can be a sign of underlying health issues, such physical or neurological disorders. By monitoring your performance, you can identify potential health issues early and seek medical attention if necessary. Additionally, tracking your performance can help you monitor your progress during rehabilitation if you have suffered an injury or illness that has affected your performance. So, take a moment to track your performance and keep an eye on your health.

Action time is reported in milliseconds and was developed as a proxy metric to the Choice Reaction Time (CRT) test, a widely used cognitive assessment tool that measures processing speed. The model that predicts action time from smartphone behaviour was trained and validate on ~700 individuals that have undergone multiple rounds of CRT testing.
