1 Introduction: SuperVario2

Congratulations on buying your new mobile Braille display SuperVario2. You have just

acquired one of the latest Braille displays which offer a new dimension in functionality,

flexibility and portability.

SuperVario2 is a new Braille display available with 24, 32, 40, 64 or 80 Braille cells. It

provides Cursor Routing keys for each Braille cell and 6 Navigation keys. SuperVario2 is the

next generation of our well known SuperVario series. In addition to its predecessor,

SuperVario2 can be operated as HID (Human Interface Device). HID devices are recognised

automatically by the operating system, no need for the user to install device drivers. This

new technology is more and more accepted by various Braille display and screen reader

manufacturers.

In the following chapters we will often write about SuperVario2 without further

mentioning the different sizes.

All these Braille Displays connect to your PC or mobile device in one of three ways:

 Bluetooth – a modern wireless connection

 USB – the modern interface for PC peripherals

 USB HID– the latest standard which connects as a Human Interface Device without

requiring device driver installation.

Outstanding battery life time of about 20 hours on Bluetooth allows total freedom and

mobility.

The intelligent charging circuit inside SuperVario2 charges the battery with a low current

while SuperVario2 is connected via USB. If connected to an optional USB charger, it will

charge with a higher current of up to 500 mA and will be fully charged up in less than 2

hours.

The highly robust casing is made from light metal. Such techniques are found in modern

camera bodies and are already used in Pronto. They allow us to construct very elegant,

stable and robust equipment.

SuperVario2 is a new milestone in the development of mobile equipment for blind users.

Their outstanding feature is the combination of the most up-to-date technology with a

tried-and-tested simple design.
