Many people have reached a point in their lives where they want to change something about their body. They want to lose weight, gain muscles and live healthier. At the same time, several people reach a point where they fail, give up or do not start at all without any strategies to conquer there weaker selves. However, asked by other people with similar struggles we change into veritable life coaches. We all have this one friend who comes up with the best relationship suggestions but is always single or the one who shares a profound knowledge about workout routines and nutrition but prefers to lie on the couch eating pizza. It seems to be easier to advise while viewing problems from above than taking action oneself. Concerning psychology, this phenomenon is called “projection” – following one‘s own goals through others. Hence the user is supposed to project his own goals on the avatar WUTZ thus coaching him playfully. The avatar evolves by completing different minigames. These games are controlled through a wearable device attached to conventional fitness equipment.

The interface of the app is kept minimalistic in order to foreground functionalities. After launching the app, the user enters the start screen displaying the avatar. This screen serves as the selection menu for each muscle group. If the avatar wants to train a specific body part, the affected muscle group is highlighted through a hotspot which represents a corresponding game. After tapping a hotspot, a tutorial is shown explaining the following game. At the end of the tutorial, a start button appears with which the Bluetooth connection is established and the game begins. After completing the game successfully the user is directed right back to the start screen. The muscle group of the avatar has grown respectively. The hotspots appear periodically in order to motivate the user to train regularly in the form of small sets. For connecting the wearable with the app, a technological basis is needed. At first, all the necessary components were identified. Because of the small constructive form, we decided to use an Arduino Mini, a 9-axis-gyro sensor for measuring the acceleration, a Bluetooth shield for the connection with the app and a status led. A rechargeable battery serves as a power supply. The case was created in Autodesk Inventor adjusted to the components as mentioned above and printed in 3d. Afterward, the case was coated with primer several times and spray painted.
