Verbatim Notes Typed verbatim notes (also known as “approximate” transcripts) are a nice alternative since they contain valuable details and quotes without the extra noise included in an audio or video transcript. If you go with this approach, instruct the note taker to focus on the interview dialogue. The note taker should not be interpreting and adding commentary along the way—interpretation happens after the session. STILL CAMERA Researchers should always bring a still camera to user interviews. It is valuable for capturing the participant’s computer setup and context of use. Also, I often take an informal participant portrait so I can associate. | Verbatim Notes Typed verbatim notes also known as approximate transcripts are a nice alternative since they contain valuable details and quotes without the extra noise included in an audio or video transcript.

This photo can be added to the participant profile which will be discussed in the next chapter. A high-end camera is not necessary an inexpensive point-and-shoot digital camera with ample storage should be fine. AUDIO As mentioned earlier audio is an effective backup especially if you have handwritten notes. You may also want to use audio to reinforce a particular finding or extract a user quote word for word. If you choose to capture audio make sure your recorder has a good microphone and there s little background noise. For a recent iPhone study I used a voice-recording app to document a user interview. Halfway through the session a construction team started jackhammering the sidewalk right next to the window. Parts of the session were audible but I mostly had to rely on my notes. VIDEO Video is the most comprehensive method for capturing participant behaviors but it can be impractical when your participant is on the go. For example It s often difficult to get the right angle when traveling in cramped vehicles or other forms of transportation. Equipment can be purchased to make the process easier but the time required to switch or adjust cameras may outweigh the benefits. Video recording in a public place may be restricted for security or privacy reasons. The amount of time required to analyze video
