Audio and video recordings can help when gathering evidence and information to help make design decisions.
Audio recordings of client interviews and user feedback can be a less invasive way of gathering information than video. Recordings can be listened to repeatedly to analyse information, and recording equipment is easily available on smartphones.
Taking photographs to record every step of development and collecting evidence helps keep track of each stage of research. Photographs can be used to record information such as site surveys, anthropometric data and ergonomics, as well as being a reference point between the designer and the client.
Video evidence can be used to help remember client or user group interviews. They can also be used to film user trials, where slow-motion replays or time lapses can be shown to identify very specific moments, such as breaking points or areas of wear.
The permission of the client or user should always be given before recordings of any of the above methods are made.
