Nicola, Yes, Isaac is right that we are the deaf-blind. Let me explain why do I am searching how to solve with our face-to-face communication.
For the example, I sit on the public bus. I could load my cellphone or handheld PC with the bluetooth to other person or driver on same bus. Then we can talk each other before we got off the bus. For the reason, sometime bus goes on the direct way because of emergency, parade, or other conflict way. Otherwise, I could use the cellphone with my PK as the modem. So I could call the bus service for the information via the relay services. I know there are some "2-ways communicatiors" devices but they require to have the table, not great for the mobile. I hate the cables for the mobiles. In the future I could have GPS and Bar Code Reader. So I might have the totally access the information in any place. Leslie--
