HearAct is a sign language interpreter for Pakistani Sign Language (PSL) that uses sensors to record hand orientation and gesture coordinates and passes that data to a recognition model to display the corresponding word or sentence. It aims to help the over 250,000 deaf or speech-impaired people in Pakistan communicate by reducing their dependency on others and enabling mobility through a portable, cost-effective solution. The project is supervised by Sir Abdul Basit and developed by team members Ayesha Dojky, Saif Rehman, Shehrbanu Karim, and Zahra Hussaini.
