NS Vending Machine

Improving the usability and user experience of the NS Vending Machine

Design Challenge

Together with my design team we had to Improve the current user experience and usability of an existing product by looking at the current usability and experience problems, redesigning a solution, evaluating the results and finalizing our design proposal.

 

  • A usability inspection was done to determine the scope or focus of the project. This included mapping out touch points of the product (shown above), a context analyses and finding usability problems from stakeholders involved.

  • User tests involved real people operating tasks within our determined focus. Observations, surveys and interviews were conducted and footage was captured for further analyses of the interactions.

  • The data of the user tests was analyzed in order to determine severe usability and user experience problems. Quantitative research included task flows, number of clicks, pr-emo tool, system usability scale and AttrakDiff. Qualitative Research included recorded interviews.

  • 4 iterations of redesigns were created and tested with peers, in order to determine the most effective way to solve our usability and user experience problems. In the end a redesigned prototype was created to test with users.

  • Our redesign was tested within the same context as the original test. This way all other existing variables would stay the same. After analyzing the new data, conclusions were drawn and a final iteration was made to present to NS.

  • During the project we collaborated with the NS. It was important to communicate our redesigns and findings to NS in order to get the proper feedback. Above is a task flow of our final redesign used to illustrate the new interaction possibilities.

Project Outcome

My team and I redesigned the NS Vending Machine, made for traveling by train in the Netherlands. After defining a scope, user interviews and observations were conducted with the current design to find usability and user experience issues. Prototype directions were created and tested with users in order to create the final redesign. We achieved a solution that makes users consider buying an OV-chipkaart, by raising awareness about its availability and increasing its findability. the overall experience had to be intuitive and the users had to operate the OV-chipkaart menu in an efficient way.

We were able to create a design that satisfies our design goal and NS plans to implement aspects of our redesign in the future.
