	What is B&D Messenger?
	B&D messenger is a small, lightweight and low priced DIY communication device that is specially designed for user with visual and/or hearing impairments to easily communicate to each other and general cell phone user. The device runs under a connection to a computer and the internet in which it will provides translation system between Braille to text and vice versa and the ability to send and receive SMS to general cell phone user. The device has two-design interface that can be chosen depending on the user condition. For visually impaired user a specially designed Braille buttons can be used to input text message, as to read incoming messages user can choose between reading by Braille movement or to have the message translated into speech. As for hearing impaired user, the interface is designed and meant to be used just like any regular cell phone.

	What was the challenge?
	There are several already made Braille products existing in the market. However, other than heavy and large in size, most of them are also highly priced. B&D messenger was designed to solve these problems. We intended to design following aspects: Cost effectiveness and Functionality. General Braille display or TTY system that are available right now are too expensive in price. To reduce its cost, B&D Messenger is built with an open source platform, Arduino and Processing. Currently, in order to keep the price low and affordable, a basic B&D messenger still runs by a connection to a computer, however if the user seeks portability a wireless connection can be made by ordering an optional Bluetooth module that can be easily attached on to the micro controller. In addition, by running under the Internet, no cost will be needed for sending and receiving messages. Small and Light. To accomplish this objective, all of the adopting materials we choose are lightweight. The triangle shape is chosen to be consistent with the other existing devices and the design was limited in accordance with the LCD size. Do-It-Yourself. B&D Messenger is designed to have a less complex construct. The case should be easy to make and ensemble with a recycled hard paper attached inside the kit. All basic electronic parts come with customized and presoldered state.
