User Testing

Design

• We

Implementation

• We use our own server to host the website. We use PHP, JavaScript, AJAX, JQuery, and HTML to implement the site.

• The back end of the site provides a MySql database that stores data provided when users use the site. Whenever a user creates a QR code for a particular event. All of the details for that event are stored in the database along with enough information to generate the QR code. The user is allowed to re-edit QR codes and update their values in the database.

• 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.

Evaluation

Getting the users

• We decided to use pairs of users to test our project. As the project involves someone creating a QR code and then another person accessing that QR code and responding to an RSVP, we figured it made more sense to use separate users and give them focused tasks instead of making them perform tasks as multiple people. We gathered three pairs of people where each pair consisted of an MIT poster maker (dorm, school, and sport) and an random MIT student. By getting three different types of poster makers and a small group of random MIT students we feel that this represents our target user population very well. The poster makers are exactly the types of users we were hoping to build out website for and the MIT students fit the role of event attendees very well.

Briefing the Users and User Tasks

• After getting the users who would participate in the test, we told them that we created a website to help with the tracking of results for advertised events.
  • Poster Maker - You are in charge of publicizing for an event. Your first task is to use our site to create a QR code that prospective attendees can scan to send an RSVP for the event. Later on, you will be tasked with viewing the statistics for your event.
  • Prospective Attendee - Your task is simply to scan a QR code, RSVP 'yes', and choose to get an email reminder/add it to your calender.
