The T3 talking tactile technology uses a laptop, CD programme and touchable icons to make information accessible.

It has been developed by the college in Hereford and a New York graphics firm.

Students say it is a huge improvement on the old system they were using because it puts them in charge of their learning without needing assistance.

'Benefits for others'

The T3 is a laptop-sized, touch sensitive device which is connected to a computer and run with a programme CD related to the national curriculum.

Its creators say any subject can be converted by the programme.

When the symbols, icons, and regions of the tactile surface are pressed sound describes what the user is feeling.

Ian Beverley, Braille technology trainer at RNC said: "I would describe it as sensational as it allows the visually impaired student to access learning resources with senses other than vision."

The team said trials are also showing the device may have benefits for other groups including people with dyslexia.
