In today's digital world many individuals spend their day in front of a computer or mobile phone for entertainment. Individuals enjoy a more sedentary lifestyle from advances in technology. This is one of the leading factors contributing to a decrease in fitness level for large parts of the populations in developed countries. We want to design a mobile role-playing game (RPG) where the character evolves based on the exercises the user performs in reality. This design can motivate and persuade a potentially large demographic of users to engage in physical activity for an extended period of time through the enjoyment of an engaging game. This novel application has shown the capability of automatically identifying and counting the exercises performed by the user. This automatic activity recognition and numeration is performed solely through the accelerometer of a single smartphone held by the user while exercising. The type and amount of exercise improve the characters speed, strength, and stamina based on the type and amount of exercise performed.
