- 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.
- QR codes are regenerated each time a new size or color is set. This was simpler than recoloring the image in JavaScript and thus we chose this way of doing it. However, based on user testing, this was a bad idea because users get confused when the QR code keeps changing.
Implementation Decisions
- 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 because we could not figure out any other way to do it.
- We decided to add red text indicating an error in text fields so that users would know 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.QR codes are regenerated each time a new size or color is set.
