An intra-oral access device

Using developments from the science of electropalatography, an intra-oral access device is being developed which increases the range and sensitivity of control available to the severely physically disabled individual. The system provides the user with a consistent positional relationship between the tongue and sensor in contrast to extra-oral mounted tongue switches. The system allows the tongue to function within the oral cavity where it has maximum speed, agility and mobility and gives the user a chance to increase accuracy through practice. A major benefit of this system is its versatility. By covering the surface area of the plate with a large number of sensors, the groups of sensors that are programmed to act as switches can take any size, shape, position and number to match the user's needs and abilities. As with any developing system, a number of problems have been encountered in practical use.
