This project aims to develop a new dual-task stationary cycling system that can monitor and provide feedback on the aerobic exercise intensity, while administrating appropriate cognitive trainings targeting various cognitive sub domains through a screen in front of the user.

The proposed system is designed to train the brain with cognitive tasks and the body with aerobic exercises at the same time. The difficulties of the cognitive tasks are controlled by the users' previous performances on these tasks so that they wouldn't be too easy nor too difficult. Similarly, the intensity of the aerobic exercise will be monitored through an optical encoder for the cycling cadence, two power meters for the force output on the two pedals, as well as a heart rate monitor for the users' physiological response. Constant feedback is being provided to the users so that they will exercise at the correct intensity to provide the greater cardiovascular and cognitive benefits.
