Imagine you are in a busy shopping centre and someone tries to get your attention — not with words, but through a series of hand gestures. You watch, trying to decipher the movements, but remain unsure. Gradually, you recognize it as sign language and find yourself wishing you understood, even just a little. You wish there were a way to translate their gestures. As TMKDT, we aim to turn those wishes into reality with Hands UP. A powerful application to help you — one sign at a time!

Hands UP is an innovative application that bridges the communication gap between signers and non-signers. Using advanced AI technology, the application detects and translates sign language in real-time through the device's camera, converting signs into both text and spoken language without significant delays. Beyond translation, it also serves as an interactive learning platform with structured lessons and immediate feedback on signing accuracy.
