Abstract

The drawing shows a device for conversation by people who have speech and writing handicaps. As shown in Fig. 1, the device has a transparent elastic layer 2 that carries written words that might be used in a conversation, an alphabet, numerals, and other characters. Layer 2 overlies a set of switches and lights so that depressing a selected point on the layer causes the legend to be illuminated. See U. S. Patent 3,777,222 for details of this construction. A grid 3 is formed over layer 2 to aid in the selection of a position. The device has a lid 4 that can be raised by releasing a latch 5, and layer 2 can be readily changed. A variety of layers 2 can be provided for particular conversation subjects.

Portable Conversation Device

The drawing shows a device for conversation by people who have speech and writing handicaps. As shown in Fig. 1, the device has a transparent elastic layer 2 that carries written words that might be used in a conversation, an alphabet, numerals, and other characters. Layer 2 overlies a set of switches and lights so that depressing a selected point on the layer causes the legend to be illuminated. See U. S. Patent 3,777,222 for details of this construction. A grid 3 is formed over layer 2 to aid in the selection of a position. The device has a lid 4 that can be raised by releasing a latch 5, and layer 2 can be readily changed. A variety of layers 2 can be provided for particular conversation subjects.

The device is powered by a rechargeable battery that is accessible through a removable plate 6 that can be seen in Fig. 2. Being light-weight, it can be held by a handle 7 or carried by a strap 8 or mounted on a wheelchair or the like by means of brackets 9 and 10. The device can carry a second elastic layer 12 and associated switches and lights. Layer 12 can carry additional words. Alternatively, it can be a duplicate of the layer 2, and the apparatus is arranged so that communication can be made from one side to the other. Thus, the device can be supported on a table in the position of Fig. 1, and two people can communicate through the two sections of the device. Similarly, the device can be electrically coupled to communicate with remo...
