- The final design of our interface keeps all of the functionality from our previous prototypes but aims to simplify the workflow to make the entire process as quick and smooth as possible.
- The home screen has been changed in response to heuristic evaluation comments, as it was originally to wide to be seen on many modern devices. We changed the format of the home screen to include a marquee instead of a ribbon of images so that the view will not be as wide. This was much cleaner and allowed to page to be displayed cleanly on all devices that we tested.
- After clicking the get started button on the home page the user is presented with an initial form to fill in the event information for that the attendees will see after scanning the QR code they are creating. Unlike in earlier prototypes where all input fields were identical in size, the event description input has been expanded into a multi row text area to be more consistent with the fact that event descriptions can often be several sentences. In response to heuristic evaluations that showed our time entry field had usability issues, this area was redesigned to include a drop down to allow users to select times without having to manually type them in. Error checking was also implemented to alert users if their date or time entries were invalid.
- After inputting event details users are brought to a page where they can customize the color and size of the QR code and then download it. Previous prototypes had divided QR customization and QR download into two separate pages. Feedback during user testing heuristic evaluation indicated that the download page, which previously showed as sequence of instructions about downloading the code and how to use it, was overly complicated for the task. We therefore decided to streamline the process. We added text field for the user to enter their email address as well as a text field containing the user’s link to the admin page, to the QR code design page, and removed the additional page altogether.
- The admin page where users can view RSVP statistics remained the same functionality wise throughout the iterations into our final design. It allows users to view a table of all those responded as well as a chart showing response numbers versus time. However, the layout of the elements on the page was updated to be internally consistent with the rest of the site. The main elements were centered, with the navigation buttons to the other parts of the site moved to the bottom.
- The heuristic evaluation noted a lack of feedback for sending RSVP responses. Therefore, we updated the view page to indicate to the user when a response message had been sent to the system.
Implementation
- We use our own server to host the website. We use PHP, JavaScript, AJAX, JQuery, and HTML to implement the site.

- The front end of our website features a simple and usable design that allows users to enter information pertaining to a particular event. Our website creates a QR code that gives potential attendees a simple way to RSVP to these events by scanning the QR code (hence the name RScanVP). The user is presented with another page of development that allows them to recolor the QR code and also re-size it within visible constraints.
- We decided to take away the "Download" button altogether. This makes it a little harder for users to acquire the QR code that has been generated. We made this decision so that the user was not redirected away from the site at any time.
- We decided to add red text indicating an error in text fields so that users would not why their submissions were being rejected. Our user testing indicated that this was a good idea but would be more helpful if it were more visible and possibly located next to the field that had the error.
