User observation
User observation study is progress
Shelf displays are being assessed for ease of identifying
and picking up different products.
User observation involves an observer (the assessor) watching users interact with the product. Ideally the observation should take place in a realistic environment, such as the user's home or work-place, but most often takes place in a specially constructed usability laboratory. The assessment is often recorded using video cameras.
Disadvantages are in time and costs involved. A working prototype must be available to assess.
