Brian / Interactive Sport Device

Everybody loves being healthy. Being healthy is the key to a happier life. Even though it is no secret that physical training enhances everyone’s health many people just lack intrinsic motivation. Drawing on this specific issue "Brian" gamifies the barbell training by demanding the user’s physical strength and cognitive skills. The application presents colors in a random order which must be memorized correctly. Each color represents a certain exercise. Executing the right exercise in the correct order leads to the next level. The famous memory-game “Simon” is taken as a basis.


All about the look

Being as minimalistic as possible BRIANs interface not only convinces by its simplicity but also by its wealth of color attracting the user’s attention. As each color must be undeniably recognized intense, distinctive colors are utilized. The basic idea designing the logo is depicting both a human brain and a male torso and two mirrored B’s standing for Brian.


(Almost) nothing left to chance

The application is coded in AngularJS and built with ionic. Optimizing the usability of the application the order of events is kept linear allowing the user to concentrate merely on the game experience itself. Launched the application the user may choose between either reading the instructions or starting the game immediately. Starting the game the user is directed to the calibration screen showing both an exercise and a corresponding color. Executing the exercises precisely leads to the actual game screen (consisting of two colors) in which one random selected color flashes up and must be repeated by carrying out the proper exercise. In the next round the first color will light up again and a second will be added. The player must repeat both exercises and memorize as much colors as possible.


Perfect Camouflage

The case design of the networked device aims to replicate both the aesthetic and the functionality of a barbell plate whilst covering the electronics and sensors inside granting access to an on-off switch and a mini-USB port to charge the battery.

The outer case was milled with a CNC machine in the University’s metall workshop and afterwards varnished with both black matte lacquer obtaining the barbell plate look and clear lacquer acting as a protective coat. Constructed in Autodesk Inventor the inner case is 3D printed and protects the electronical parts of the device.


What's inside?

To regulate all different modules an Arduino Pro Mini is used as core part of the electronic communicating with the application via a bluetooth module. The power is supplied by a lithium ion battery which can be recharged. In order to track the exercise’s motion a barometer is used determining height differences and a gyroscope providing the acceleration on all three axis.
