For many multimedia applications, screen buttons may be represented in many different way such as standard grey 3D button, a circle and a label, or simply as a graphical shape or part of a graphic, drawing or image. It is important that the user can determine which elements of a screen are buttons so that they know to press upon then. The easiest way to achieve this is by making them look like 3D buttons as they are well recognised in Windows style interfaces. However designers often want to achieve a distinctive design that looks different to the standard. Here it is important that buttons have a consistent appearance. With the technique of providing a spot and a label (such as a location of a town on a map) the user may be unsure whether to click on the name of the town or the spot itself. It is therefore useful to alow them to click on both. Where buttons are placed in a row, such as on a navigation bar, they should be grouped sensibly together and placed in a logical sequence.
