The 3-sentence summary is: The usability report summarizes testing of a John Mayer guitar tutorial video, finding that participants felt the formatting and structure were good overall but some requested showing finger placements and re-explaining chords. Most participants said they would recommend the video and successfully learned the song, leading to the recommendation to add finger diagrams and make minor changes.

Guitar Playing Experience

We designed the project for
intermediate (or moderate) guitar
players, so we wanted to make sure
that we are surveying in our intended
demographic. The recommended
number of participants is 5, however
we ended up with three participants
due to time constraints and
availability.

Usability Test
Methods For the remote test, we sent two
surveys and the link to the video to
the participants via email and then
analyzed their responses.
We asked each participant to fill out
the pre-survey.
They were then given the scenario.
Imagine that you are wanting to learn
“My Stupid Mouth” by John Mayer. You
do a YouTube search and come across
this video.
a) Play the video
b) Watch the video and follow the
instructions
c) Feel free to rewind and replay the video
as many times as necessary.
Finally, they were asked to complete
the post-survey and then send the
surveys back to our team via email.

Show the tabs and finger

just saying where to put the fingers.
