Future Work 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 Lighter 1 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 Laura Housley  Can store all musical scores in one location  First auto-scrolling, score projecting, musical aid for low vision musicians  May lead to low cost solution for low vision musicians Figure 1: Score Scroll Page Figure 3: System Architecture Diagram  Input: MusicXML ™ file  Maintain hierarchy of music alongside of hierarchy of views  Programmed with Java for Android Honeycomb Figure 5: Screen Flow Diagram  Shows the flow of screens that a user may view while using our program.  As shown, each screen is able to return to the previous screen. Figure 7: Proposed Options Page Functionality  Work through scrolling issues involving note placement  Add the ability to select individual staffs  Add a metronome sound option  Fix lyrics so they scale and locate themselves appropriately  Add additional symbols/directions such as “piano”  Fix stem and beam issues such as cross-staff beams  Handle “poorly” formed MusicXML ™ files Interface  Finish implementation of additional menus A special thanks to my previous teammate Michael Jewitt, my advisors Rajiv Ramnath and Peter Rogers, my sponsors at The Tony Wells Foundation and Columbus Vision and Vocational Services, and my trial users at The Ohio State School for the Blind.
