Background

Abstract

Client Requirements

Final Design

  • Case Features

  • Protects iPod

  • Provides tactile feedback to user

  • Prevents accidental selections

  • Made of ABS plastic

  • Dycem® backing prevent slipping

  • Easy screw disassembly

The goal of this design project is to develop a user-friendly mp3 player for elderly cancer patients. Current designs of mp3 players are difficult to operate for elderly people with limited motor skills and minor disabilities. Research indicates that music is an effective way to induce relaxation and distraction for patients to help manage pain and fatigue without the use of drugs. In order for music therapy to be an effective treatment in pain therapy, patients must be able to operate mp3 devices. By creating a mp3 player that is easy to use, patients will be able to take full advantage of music therapy.

  • Player capable of playing 12 relaxation exercises

  • Simple menu navigation

  • Easy-to-see screen

  • Easy-to-use controls; regardless of age or motor control

  • Less than 250 grams

  • Ability to record songs played (if time permits)

  • Ability to administer patient surveys (if time permits)

Figure 4. Custom-made case designed specifically for the iPod touch and our program.

Apple iPod Touch

  • Menu Features

  • Simplified interface

  • Four categories of songs

  • Three songs per category

  • Large buttons

  • Color coded options

Physical modifications and add-ons to current devices were deemed too complicated or too expensive. An Apple iPod Touch has the biggest screen of all current mp3 players. This device is able to download customized applications which can provide a way of enabling elderly patients to navigate playlists with ease and experience relaxation therapy. Applications can be programmed to have large buttons as well as a simplified arrangement.

Relaxation therapy has been used by nurses to help patients cope with pain, fall asleep, and improve mood. There are four main categories of relaxation therapy employed by our client. They are: nature sounds, nature imagery, symptom focused, and relaxation exercises. All four classes can be incorporated into current mp3 players to make the therapy convenient for the patient, as well as the nurse in charge of administering it.

Figure 5. Menu progression within the program we wrote. The first menu displays the 4 song categories, the second displays the three songs of that category, the third controls the song currently playing

Motivation

Figure 2. The Apple iPod Touch has a larger screen than many other mp3 players.

Doctors and nurses are hesitant to implement relaxation therapy because they are unsure of the best way to do so. Dr. Kwekkeboom of the UW Hospital has been using iPod nanos as a means of administering this audio therapy. Research has found that, though patients like learning to use the iPods, the current devices are troublesome for elderly patients with arthritis or vision problems. A user friendly means of relaxation therapy is needed to allow all patients the opportunity to self administer this beneficial treatment and increase acceptance within the healthcare profession. Furthermore, since Dr. Kwekkeboom’s work involves research, it is desirable that the mp3 player be able to record the songs played and allow patients to fill out a short survey after each “dose.”

Future Work

  • Finishing touches on the program

  • Make program available via app store

  • Write program to record user song selection and surveys

  • Testing

Programming

Creating our own iPod application allows us to simplify menu navigation along with the button arrangement. The 12 exercises can be incorporated into the program and played through the iPod touch.
