Popular mobile games can be used to detect signs of cognitive decline -- ScienceDaily
Their research put 21 healthy participants through standard paper-based cognitive assessment tests, followed by 10-minute sessions of playing Tetris, Candy Crush Saga and Fruit Ninja over two separate periods, a fortnight apart. The three games selected were chosen because they are easy to learn, engaging for most players and involve intensive interactions using multiple gestures.
Using the sensors built into the mobile phones to collect data, the team showed how users interacted with the games and illustrated a clear link between the subjects' touch gestures, or taps and swipes, their rotational gestures and their levels of cognitive performance. The study revealed the participants' ability to perform visuo-spatial and visual search tasks, as well as testing their memory, mental flexibility and attention span.
