In today’s technologically advanced century, gadgets and software keep flooding in the market continuously. There is ever increasing research being done in company labs, universities, to make our lives easier, faster, safer, connected, convenient and fun. We want things to happen in split seconds, our messages to reach people across the globe as soon as we think it. The concept of augmented reality is one such topic that is becoming more and more ‘real’ in today’s world with each new innovative gadget and technology in market. The term Augmented Reality refers to any man made gadget that can sense the environment and supply users with information based on that. Google-Glass is such a wearable computer device with augmented reality display. It displays information in a hands-free format, while communicating with internet using natural language voice commands. All the communication and storage is carried out via Cloud services, and has complete smart-phone like functionalities such as camera, video, messages, mailing etc. This project uses a similar design and idea with limited functionalities and scope. The main objective is to implement audio sensory devices on the wearable glass device, process the signals from Microphone attached, remove unwanted elements like noise using implementation of filters, amplify, combine surround sound from various microphones strategically placed on the device to provide directional sound effects and then conduct the sound to the user’s brain directly using Bone Conduction technology. Thus, we focus on audio sensing and processing, so that the device is able to provide augmented spatial enhancement unit to hearing abilities. It can also work as a modern and stylish hearing aid with reduced cost. It will be essential to the user in noisy environments where communicating effectively can be challenging some times. The mobility and easy to use interface of the device makes it attractive and suitable for all types of users. Additional enhancement features include visual (camera) components and remote data storage capacities which are discussed in the further scope of expansion chapter of the report.
