This title, roughly translated as "Nintendo Switch Training for Adults with Brain Training Supervised by Prof. Ryuta Kawashima, Research Institute for Aging Medicine, Tohoku University" (probably something shorter if an international version is released), will also use the Switch's unique features like motion control, the IR camera to record hand movements, and also its touch screen. Indeed, a capacitive stylus, reminiscent of the NDS, for handwriting answers on the screen will be sold separately.
Another feature is the ability to track one's progress through a phone and also share the results with family and friends. Additionally, to keep up with your brain training, the game will send you reminders in docked mode by buzzing the Joy-Con and also apparently by flashing the home button’s LED.
The new Brain Age game will be released in Japan this December 27. No word on an international version at the time of writing.
