Abstract: A language interface system and method to be used, preferably, by the deaf, hearing impaired, mute persons or visually impaired is described. The language interface method is implemented through an electronic computer system/device which selects a setting mode, receives input in the form of language, audio or of an image, interprets the input as written language, spoken language or an identifiable physical object image depending on the setting mode, and produces an output depending on the setting mode. The setting mode is selected from a group of input/output modes comprising language mode, noise interpretation mode or visual interpretation model. The language interface method may be embodied and implemented in, but not limited to, mobile devices such as an Internet-enabled mobile phone, PDAs, tablet computers or wearable computers with an optical display embedded in glasses.
