The design problem was to find an easier way to show people the 1.5 meters. To make this teaching simple and friendly, common references were used such as steps, cats, snake etc. The design evaluated the user to think by asking about 1.5m but now giving the answer. Showing the user the distance from known objects and asking them to evaluate the lengths of the objects has put the user in direct target, however a clearer continuity between images was needed.
