The risks associated with the occasional use of computers in art and design education are thought to be very low. Concerns are being expressed, however, in relation to very low-frequency radiation, eye disorders and posture-related stresses. Teachers need to be aware of the potential for physical problems through the use of computer equipment without suitable seating and positioning of a keyboard, mouse, graphics tablet or VDU, in such ways as to minimise risk. Teachers should be aware that some photosensitive pupils may have an attack of epilepsy triggered by use of the VDU, particularly where older computer screens are still in use. Such cases are rare, but it is sensible to take simple precautions by checking their suitability.
