Learning Sign Language: Gateway to an Inclusive World

The Fingerspelling Simulator above is the first step to getting to know Deaf communication. However, sign language is deeper than just spelling letter by letter.

1. The Concept of "Mother Tongue" for the Deaf

Many ordinary people misunderstand, thinking that Indonesian is the first language of Deaf people. In fact:

• First Language: For the Deaf, their mother tongue is Sign Language (Visual). Their brains process information through images and movements, not sound.
• Second Language: Indonesian (spoken/written) for the Deaf is a Foreign Language. They have to learn it like Indonesians learn English (memorizing vocabulary and grammar that has a different structure).

This is why in everyday communication (BISINDO), the sentence structure is often different from standard Indonesian (SPOK), because it follows visual logic.

2. BISINDO vs SIBI: Which to Choose?

Understanding the concept above helps us put the use of BISINDO and SIBI proportionally:

• BISINDO (Indonesian Sign Language): Is the natural language of the community. Use this for social communication so that the conversation feels fluid, intimate, and fast (without having to translate every affix).
• SIBI (Indonesian Sign System): Is an artificial visual grammar system. Use this in the academic realm (school) to help Deaf students understand the structure of Indonesian grammar (such as the use of prefixes me-, ber-, suffixes -kan) in written exams.

3. Ethics of Communicating with Deaf Friends

Sign language is not just about hands, but also culture (Deaf Culture). Here are basic tips:

• Eye Contact is Mandatory: Do not break eye contact when a Deaf friend is "speaking" (signing). Looking away is considered rude (like covering your ears when someone is speaking).
• Getting Attention: Tap their shoulder gently or wave your hand to call them. Do not throw things.
• Lighting: Make sure your face is well-lit so that your expressions and lip movements are clearly visible.
