Software Analysis and Design

20% of Americans age 50 and older play an instrument.

21.7% of adults over age 75 suffer from vision loss which persists while wearing corrective lenses.

Facts

As people age, the gradual or sudden loss of their vision may greatly hinder their ability to engage in meaningful activities. For musicians, this may include performing in an orchestra, band, or choir.

Low vision impairments can make reading sheet music impossible.

Problem

This software will allow musicians with low vision to read sheet music by having it displayed in the size, color, and brightness of their choosing.

Music will scroll at any tempo across the screen and allow users to keep a large library of music for easy access.

Additionally, this software will have a simple user interface designed in a way that is intuitive for older people.

Project Goals

Currently, devices are either very expensive or insufficient. The Lime Lighter1 costs $3995 dollars for the device alone without any software.

Some musicians use enlarged sheet music, but this requires a helper to turn pages very frequently since only a small amount of music can fit per page.

Current Methods

Can store all musical scores in one locationFirst auto-scrolling, score projecting, musical aid for low vision musiciansMay lead to low cost solution for low vision musicians
