01. Formative Study
To identify the key challenges and needs in authoring user tutorials, I conducted a formative study consisting of two parts: a video coding analysis of 12 tutorial videos on YouTube, and a remote user study with 10 participants for observing and understanding how they create tutorial videos.
The goal was to make it easy to author content in AR. In order to do that I had to explore and understand two different user groups: Those who create tutorial content (creators) through an authoring mode and those who consume tutorial content (consumers or new users), access mode:
Looking at a system with two different user experiences forced me to piece things together and figure out what kind of flow translates to a different user. In other words, what kinds of things does the authors have to do, say or show that will be of importance to the people consuming the content.
Video Coding Analysis + Codebook
The goal of our video coding analysis was to understand how existing tutorials are made, through observation, and to summarize the types of feedback and guidance used to convey a step in the tutorial. After analyzing 12 tutorial videos, I created a code book introducing the hierarchy of types of feedback on devices given by creators of tutorials. View the codebook here.
For the second part of the formative study, I designed a study that would allow me to Explore how people create video tutorials. By analyzing descriptions and patterns participants share when creating tutorial content could help me identify what could be incorporated using Augmented Reality.
What was challenging about creating the video tutorials?
What kinds of things would authors want to change?
How is the tutorial process narrated?
How does the author feel about their tutorial?
How was the video tutorial produced?
What kinds of objects were used?
Study Set Up
During the study, participants were asked to independently create a tutorial video that would walk a new user through a task on a device they had at home. Once the tutorial video was created and uploaded, I used the code book to code the videos participants made. This approach allowed me to observe what participants did in their video, and probe some questions about their process. While interviewing with participants, we watched the tutorial videos together and had participants think aloud about their video. This allowed participants to review their video and answer questions about their experience while creating a tutorial. I then interviewed participants about their experience creating the video, as well as their consumption of tutorial video content. I then grouped responses from our participants in an affinity diagram
to help my team with analysis and guide us through our design.
