The surface area of each of the two cover plates is smaller than half of the surface area of said first heat exchanger plate.

Abstract: The invention relates to a method and electronic apparatus for performing computer-aided rehabilitation exercises based on video games. The apparatus comprises a data processing module connected to a memory module to memorise the video games. In addition, the apparatus comprises a display module of the video games connected to the data processing module and at least one electronic input module connected to the data processing module suitable for interacting with a user to generate sequences of digital data representing movements of the user's body during the rehabilitation exercises. The data processing module is configured to compare the sequences of digital input data with reference parameters to provide information to the user during the game representing a biophysical feedback of the rehabilitation exercise performed by the user.
