Product Features
The AudioNav keypad is an ADA compliant assistive USB device offering menu navigation by means of audible content description.
Users with impaired vision, reading difficulties or impaired fine motor skills can navigate through menus or directories that would typically be presented on a visual display or touch screen. Screen content is represented and summarised by recorded or synthesized language via a headset or handset.
This provides a set of menu selection keys which are differentiated in a way that makes the product easier to use by people with visual impairment. In addition, a standard 3.5mm headphone socket is provided. This allows customers to plug their headset into the module and receive audio instruction to help them navigate the use of the equipment.
The externally mounted version of the AudioNav provides options for manufacturers and operators to permanently affix an AudioNav device to the outer casing of a host terminal or to adjacent surfaces such as walls or service counters. This is especially useful when existing self-service installations must be upgraded to meet current accessibility mandates.
An optional Quick Release Cradle’ allows the AudioNav to be detached from the host system for use as a hand-held device. In this hand-held configuration AudioNav can, if required, be passed directly to any user with limited reach or impaired dexterity. Used in combination with SpacePoleTM products this externally mounted version of the AudioNav can be conveniently positioned and adjusted to ensure maximum accessibility. The Extended Footprint version “AudioNav EF” adds volume and playback speed control keys. By use of the utility software, default illumination status andwake-up’ behaviour can be selected. The USB codes can also be changed. Connection to the host is via a single USB cable.

keys : – A 4 way directional key providing UP, DOWN, LEFT and RIGHT navigation. – A central ENTER key – An illuminated audio volume key – Additional keys on the EF version – Illuminated 3.5mm audio jack socket (illumination under software control) – Orientation switch in underpanel version to allow portrait or landscape mode. – Mini-USB socket for connection to host (external version has fitted cable) – Ground point for additional ESD protection.
USB Interface – HID keyboard – Supports standard modifiers, i.e. Ctrl, Shift, Alt – HID consumer controlled device – Advanced audio device – No special drivers required – Audio Jack Insert / Removal sends USB code to host – Versions with microphone support need to be set as the default recording device in the Sound Panel – Products with microphone support have been tested with the following voice assistants:- Alexa,
Cortana, Siri and Google Assistant.
Bluetooth – Option to include Bluetooth functionality so that the device can be used with the Touchless-CX app. – This is disabled as factory default, Support – Windows compatible utility for changing the USB Code Tables – API for custom integration – Remote Firmware update support

Bluetooth Interface The Storm Touchless-CX app enables kiosk users to intuitively navigate content displayed on a kiosk
touchscreen. This is achieved using their personal smartphone or tablet device, without having to physically touch the kiosk screen. This touchless kiosk interface minimizes the transfer of bio-hazardous material and may also improve accessibility for those with limited reach or dexterity. The user downloads the Storm Touchless-CX app to their smartphone or tablet device (the app is available for free on Playstore and Appstore). They can then use the kiosk directly via the Audionav. Note that audio content over Bluetooth is not supported.
The AudioNav stores an identifier (this is initially set to be the serial # of the AudioNav, can be changed using the software utility – usually changed to be the name / identifier of the kiosk in which it is installed). An overview of operation is shown below.

To enable the Bluetooth function orient the device correctly as shown and follow the instruction below :-

For the AudioNav

Press in order and hold all at the same time for 5 sec : Centre + Left + Volume

For the AudioNav EF Horizontal ­ Vertical ­

Press in order and hold all at the same time for 5 sec : Select + Left + Speed Up Press in order and hold all at the same time for 5 sec : Select + Down + Volume Up

After you have pressed the keys the LEDs will flash to confirm that you have enabled Bluetooth.
