With this in mind, I conducted Fly-on-the-Wall observations of Prime students and learned that most students use a water bottle, regularly refilling them throughout the day and keeping them within arms reach at their workstations. Some students customized their bottles with stickers, and most had some way of attaching them to their bag if they didn't have a pocket on their bag.
After observing the students, a Heuristic Analysis was conducted of the current water bottle to see if there could be any improvements to the current design.
After the Heuristic Analysis was done, concept sketches were done to see if there was an opportunity to add to the design or usability of the water bottle. Knowing that most Full Stack students use such websites as Stack Overflow and GitHub for answers to common coding problems, and that it can be time consuming looking up quick answers. To address this, a coding "cheat sheet" was placed on the sides of the water bottle so that the students had quick access to the information that they could use. To accommodate a lot of information, these reference guides would be printed very small (4-5 point type) with a plastic cuff that could rotate around the bottle and had a magnifying lens in it to make the code legible.
After a low fidelity prototype was constructed, user interviews were conducted to measure the bottle's value as a code resource and desirability as a water bottle. From those interviews, it was determined that the students wanted:
When asked about the coding references on the sides, the students were very enthusiastic about having a quick reference guide:
After conducting these interviews and gaining these insights, it has been determined that a high fidelity mock up will be needed. To move forward, more research will identify any shortcomings or strengths of the water bottle and the cheat sheet, such as:
To do this, a variety of methodologies will be used:
Questionnaires Along with user interviews, having questionnaires will provide insights into how users will interact with the cheat sheets and what content will be the most useful to them.
Interviews Following up after the questionnaire, interviews will be conducted to probe further into what the users think about the bottle itself, what content in the cheat sheets would be the most relevant to them and to find out what other information could be or should be included in the cheat sheets.
Evaluative Research To collect feedback not only on the performance of the water bottle and cheat sheets, but the aesthetic and emotional preferences that users have.
Ergonomic Analysis To see how users interact with the water bottle itself, the Ergonomic Analysis method would see if the bottle is to big/small, if the opening is wide enough and how users felt about the clip vs. strap.
Think-aloud Protocol Along with Ergonomic Analysis, the Think-aloud Protocol method will be implemented to ask the user what they are thinking as they interact with the bottle and cheat sheet.
