  • people to talk to
  • alternatives

We called it “Networking for components” or “Networking and suppliers”.

Prototype overview

Facts can get confusing when you are handling a big project over a relatively big period of time. The way solved this problem was by doing a graphical overview of what we have and what we want to have, using paper and post-its.

  • a PromComfort employee will manage the data just by passing by the wheelchair and initializing a wireless connection with his smartphone

The user interface

The fastest and most efficient way we can deliver a user interface is by creating an Android app. The app must enable the user to do the following:

  • check current pressure value
  • adjust current pressure
  • set a minimum pressure value

The interface should be straight-forward an minimalist, emphasizing on functionality rather than design. Bellow, there are 2 print-screens of the current Android app mockup.
