VIIB is an interactive sports device build for attracting more attention on the really important things in our life. With a clear view VIIB lets you perceive your surroundings with other senses. The service creates individual nordic walking routes and navigates the user through different vibration patterns in the handles.
First, we had to think about our prospective target audience. We generated massive background knowledge by doing contextual interviews and surveys. After all evaluation, we separated our task into many smaller tasks. This enabled us to iterate and improve our work each session, speeding up the process significantly. Right from the beginning various factors had to be taken into account.
The primary goal was to keep the users eyes away from the smartphone. How can we communicate with the user without distracting his attention? In constant contact with the handles we found a way to transmit the directional instructions. To avoid misunderstandings it was important to translate the directional instructions into simple vibration patterns. Vibration on both sides means attention. This one is used for getting the full attention of the user and to prepare him for a change in course. The short pattern for example in the right handle means that the user should prepare for changing the course to the right. The prominent long pattern means that the user should immediately change his course and continue it in the respective direction.
Built with IONIC framework the application is a hybrid wich runs on all common operating systems. Different settings like adjusting the right height or selecting different color themes for the poles can easily be made directly in the application. The essential features are tracking all your activity and to pick from existing routes to have a great sport experience.
The handles are precisely constructed in Autodesk Inventor. An acrylic ring with a RGB diode inside is placed at the bottom of both handles. The diodes generate the color combinations selected in the application. Little vibrations motors are installed in the handles to produce the patterns for the directional instructions. A HM-10 bluetooth 4.0 module takes care of the connection between VIIB and the smartphone. The smartphone is only connected to one pole via bluetooth. Directional instructions wich are intended to the other pole are transmitted via a nRF24L01 radio module. All components run on an Arduino pro mini and were installed in the 3D printed handles
