ABSTRACT:
What is disclosed are various embodiments of a removable control panel for multi-function equipment for the alternative navigation and selection of various available options presented. The embodiment of FIG.7is shown comprising four arrow-shaped buttons so the impaired user can navigate controls and options displayed. An ENTER button is provided for formalizing the entry of desired selections, where required. An UNDO button is provided to de-select entries. A STATUS button initiates audio, visual, or tactile feedback as to machine state, status, and other assistance. An ENLARGE button is provided by which a visually impaired user can enlarge their current focus for easier seeing and reading. An ON/OFF switch enables/disables feedback for use in those work environments where such assistance is not desired. Each of the buttons has an identifying shape, which can be differentiated by feel, and Braille and other text are additionally provided. This particular embodiment further advantageously comprises an interface jack for use by those users who make use of communicative devices. The present device is removable from an accessible holding carriage for use by persons working from either a wheelchair or from a prone position.
