The Commission on Maps and Graphics for Blind and Visually Impaired People (part of the International Cartographic Association) maintains a web site with details of recent and current research into tactile maps and other tactile graphics. They also send out a newsletter to people who register at their site. The newsletter is offered as a forum for discussion about tactile graphics, and is a good way to find out about conferences that may be of interest, jobs in the area of tactile graphics, and so on.

NCTD: National Centre for Tactile Diagrams
http://www.nctd.org.uk

The National Centre for Tactile Diagrams (NCTD) was set up in 1999 to provide practical assistance and guidance in the production and use of tactile graphics, as well as trying to improve standards through research. The NCTD runs a variety of training workshops and a series of national conferences on tactile diagrams. They are currently compiling a national database of existing tactile diagrams available from diverse sources, with the aim of making these more widely available.

Dr. John Gill of the RNIB's Scientific Research Unit maintains a web based information source for people working in the field of visual disabilities. The site includes a register of researchers in the area which can be searched by researcher's name or by subject. The section headed 'Tactile Graphics' includes about 25 researchers around the world (with an outline of their research and links to their home pages where available) and is a good way to get an impression of what is going on currently.
