Product Features
Kiosks, ATMs, ticketing machines and voting terminals usually present information about available products
and services via a visual display or touch screen. NavPad™ is a highly tactile interface that improves
accessibility, making audio navigation and selection of screen based menus possible. An audio description
of available menu options is transmitted to the user through a headset, handset or cochlea implant. When
the desired menu page or menu option is located it can be selected by the press of a distinctive tactile
button.
Storm Assistive Technology Products provide improved accessibility for those
with impaired vision, restricted mobility or limited fine motor skills.
The Storm NavPad is intended for use as the tactile/audio interface for any ADA
or EN301-549 compliant application.
Coloured and backlit keys make the 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.
