NavBarTM & Audio Module Technical Manual
Product Features
Kiosks, ATMs, ticketing machines and voting terminals usually present Information about available products and services via a visual display or touch screen. The NavBarTM is a highly tactile interface that have been designed to facilitate audio navigation of software applications by those with sensory or mobility impairment. An audio description of available menu options can transmitted to the user through a plug-in audio headset. When the desired page or menu option is located, it can then be selected by the press of a distinctive tactile button.
An important feature of the module is that it provides compliance as far as is practicable with various country standards for equipment use by disabled people, including the Americans with Disabilities Act (ADA ­ USA) , the Disabilities Discrimination Act (DDA ­ EUR) & the Equality Act (UK)
Internal colour coded illumination makes location of individual keys much easier for those with partial vision. The keytop’s distinctive shape and tactile symbols provide the primary means of identifying a key’s specific function. The intensity of keytop illumination can be adjusted or turned off when not in use.
By use of the NavBarTM utility software, default illumination status and `wake-up’ behaviour can be selected. The USB codes can also be changed. Connection to the host is via a single USB cable.
