Abstract

• The objective of this project is to construct a
  multiple audio device for the elderly. The
  device will be designed to be a user-friendly,
  aesthetically appealing, and inexpensive. The
  multiple audio device is unique as it combines
  many of the current technologies into a single
  product specifically designed for the older
  generations. Current devices are geared towards
  a younger audience and only contain a single
  functionality. Ideally, the device would be used
  on a daily basis with limitless future add-on
  capabilities. As a design team, we offer our
  constructed prototype and justification for our
  design. The ultimate goal of this project is to
  improve the quality of life for the older
  generations by shaping modern technology to their
  needs.
