Interaction design & graphic design - User testing - Proto.io

Sometimes small adjustments to an interface can make a huge difference for the people using the tool on an everyday basis. In the hearing aid industry, knowing how much amplification the instrument can perform is essential in order to sell an solution that is able to fulfill the needs of the customer for a reasonable timeframe.

With minor graphical changes I enabled the user to quickly asses the maximum possible amplification of the hearing aid. Furthermore by adding specific individual graphs to the selection of ear tip model, a total clarification of the entire package is presented at an early stage of the fitting session, securing the reseller that the package assembled is in fact the right product for the customer.
