Abstract
Conversation spaces of sign language signers were analysed according to the four following aspects: 1. Analysis of signers conversation' outset. Two conditions for starting a conversation between two signers have been found, that is to say, eye contact or being in a range of possibilities in which signers can touch each other. 2. Anlysis of the distance and angle between two standing signers. The most suitable distance for conversation is about 200cm, and the most suitable postion is facing each other. 3. Analysis of the distance and angle between two sitting signers on a table. When signers are adjacent to each other, the conversation becomes difficult, and they tend to incline their backs. 4. Readability is greatly controlled by eyesight and eye agreement.
