The AGC provides the functionality of handheld scientific calculators commonly used in the classroom. Operating on a flexible Windows platform and augmented with audio and tactile feedback, the AGC provides an alternative for people who cannot effectively use a handheld calculator, or those seeking a more interactive interface.

The AGC is accessible to anyone who can use a computer, regardless of ability, allowing the user to concentrate on math, not on learning the tools to access it.

Universal- use features include:

  • Describing of graph shape through audio tones and cues
  • Speaking menus
  • Scalable visual display
  • Keyboard navigation
  • Tactile output options

New Features for AGC include:

  • Advanced matrix functions
  • More powerful expression evaluator
  • Ability to locate polar coordinates
  • Display multiple graphs and find intersections
  • Faster computation time
  • More statistical functions

The Tiger system has been very easy to learn and takes very little effort to translate visual information into tactile and Braille formats in a timely manner. I highly recommend the Tiger to all my colleagues who work with individuals with visual impairments.
Our Tiger graphics surpass by far what I have seen any other Braille printer produce.
I am studying mathematics and accounting and financial management at Loughborough University and it is the first time that I have been able to receive all my maths in a tactile format since I started.
The Tiger can certainly make the kind of Braille text everyone is used to in a quality unexcelled by any other embosser. However, it can also make Braille of a kind never before touched by human hand.
