Depending on your project, you might want to make general observations of something that already exists - for example, how people move around a shopping centre, or how people in the street use their mobile phones. Or you might need to create specific situations to test a design. This could mean observing how people complete a specified task on a computer in a simulated environment, or observing how people use a prototype of a new product.
You could...
...record your observation through photos or video. This lets you analyse the material after the event (and even catch important details you might have missed, like the expressions on people's faces). Photographs or videos can also provide evidence to show to other partners or stakeholders in your project.
