Shadowing consists of becoming the user's shadow for a certain time and while doing what you want to understand. The objective of this observation technique is to collect information about the user in order to know him in depth: what he does, what his routine is, how he makes decisions, what he needs.
The accompaniment must be done interfering as little as possible and documenting the experience through photos, videos, notes or drawings, a material that is later reviewed to draw conclusions about the user's behavior. The insights captured with the shadowing technique help to design a product or service more adapted to the real needs of the consumer or client.
