  • Patent number: 10690320
    Abstract: To provide a user with descriptive images for each function performed by a button, the embodiments described herein use a transforming graphical expression that presents different images depending on the particular function the button is currently performing. For example, if the button is used to increase speaker volume, the graphical expression may display plus sign, but if the button is currently being used to navigate through a display menu, the graphical expression may be transformed into an arrow to indicate the direction a selection element in the menu moves if the button is activated. Thus, as the current function of the button changes, the graphical expression presented to the user also changes. In this manner, the same button may be used to perform multiple functions while presenting to a user a customized graphical expression indicating the current function of the button.
