Intelligent guidance in the healthcare domain using mobile technologies is an important development since users can benefit from the individual exercise plans that are specifically designed for their purpose, demographic information and health background. Furthermore, with the system continuously tracking their activities, the users are motivated and guided to complete their daily specified exercises. The developed system determines the specific exercise program suitable to the user with case-based reasoning. With the help of the accelerometer and gyroscope facilities of a mobile phone, users' activities are recognized and classified using KNN (K-Nearest Neighbors) algorithm. Based on their individual exercise routine and the performed activities in the current day, the rest of the exercises are calculated and presented to the user as a message to guide and encourage them. For the evaluation, the system is tested by users, and a questionnaire is conducted. The results show that the system is found to be beneficial and effective by all the participants.
