🔑Concepts
Communication is the process of sharing information, thoughts, and feelings. While we usually speak, we can also communicate without using words (non-verbal communication).
People who cannot hear or speak use Sign Language to communicate. It involves specific hand movements and finger positions.
Gestures are movements of the hands, arms, or head to express an idea or meaning. For example, nodding the head for 'Yes'.
Facial Expressions are used to show emotions. Our face can tell if we are feeling happy, sad, angry, or surprised without saying a single word.
In Indian Classical Dances (like Bharatnatyam), dancers use Mudras (hand positions) and Bhavas (facial expressions) to convey stories and emotions.
Lip Reading is a skill used by people with hearing impairments to understand others by watching the movement of their lips as they speak.
Sensitivity: We should be empathetic and helpful toward people who have challenges with hearing or speaking.
