LED-lit keys help visually impaired operators
An
EAO product story
Edited by the Manufacturingtalk editorial team
May 3, 2005
For sight-impaired operators who cannot distiguish between red and green, keypads with bright blue key illumination, generated from high quality LEDs, can now be specified.
EAO, the expert partner for Human Machine Interfaces has delighted engineers designing keypads into applications for disabled users by offering a new option of bright blue key illumination, generated from high quality LEDs.
This is now available in EAO's highly popular S.series keypad range.
Visual impairments, which often include the inability to distinguish between the colours red and green, can result in problems for users operating keypad driven devices.
EAO's easy to read, blue illuminated S.series keypad is also available with a 'blind pin locator', which can be found on key 5, together with raised characters including 'o' and 'x'.
EAO also offers full keypad customisation services including solutions for full colour front plate designs as well as laser engraving and marking.
The visually impaired may also benefit from a 'Tiresias' font option, which has been specifically designed to aid legibility.
Available with either 12 or 16 keys, and in a choice of standard, telephone, or hexi-decimal II configurations, EAO's S.series keypads feature a front plate and anti-pull-off keys constructed from Zamak that deliver a high level of vandal-resistance.
The S.series is tested to 4 million operations and is protected to IP67.
The highly aesthetic, rugged and robust features of the S.series makes it ideally suited to meet the needs of public environment applications including access control, banking and public telephones.
EAO's S.series keypads have also been successfully implemented into vending machines and industrial machinery.
