Augmentative Assistive Communication (AAC) Project Criteria
• Versatile Communication Tool– Adaptable content for multiple user accounts– Ability to record or create phrases– Customizable format for various communication and mobility levels
• Inexpensive– A communication tool that is significantly cheaper
than commercially available solutions
• Easy to use– Small learning curve for therapists and caretakers– Comfortable and customizable interface for patients

St. Vincent’s Current AAC Devices
Picture Board Handheld Touch Screen Device
•Simple word identification
•Time consuming to modify
•Therapist records each word
• Aids in more complex communication
•Easy to modify content
•Ability to form phrases or use for simple word identification
Solution – Webpage and touch screen interface
• Solution: Use a touch screen interface for a website to help children communicate.
• There are two stages of the website:– Static– Dynamic - customizable
• Both websites will use the same basic layout and principles
• Static website is already in use at St. Vincent and can replace simple picture boards
• Dynamic website has been created but needs the customization interface

Work Done to Static Site
• New sounds– Male and female voices– More phrases and words recorded
• CSS (Cascading Style Sheets)– Easier to modify layout of all pages
• Improved auto restart time– Used for children who can’t use the back button– Set to two minutes
Therapists requests for the Dynamic Site
– Customizable content for each patient– Ability to record or create phrases– Flexible page layout for children with varying
mobility levels– Easy to set up an account and use
Dynamic Implementation
• Primarily utilizes PHP and mySQL database backend
• Three database tables are used to store individual user information– Users– Numeric Table – Entries Common
Users• Each user will have:
– Login– Password– E-mail– Preferences
• Girl or Boy voice• Pictures per page• Other Information

Goals for Next Semester
• Design user creation process– St. Vincent creates the account and the user creates
their pages• St. Vincent would have an administrator like account to
create users
– How the user creates a profile• Preferences, pages, change password and preferences
• Page by page layout of customization• Design uploading process of custom images and
sounds• Research security issues

St Vincent’s Pediatric Patients
• Pediatric patients have:– Cerebral Palsy 40%– Autism 30%– Orthopedic 10%– Brain injuries 5%– Muscular Dystrophy 5%– Genetic Disorders 5%– Down Syndrome 5%
• Toy Team works with Moriah– Approximately 40 children– Most are 4-7 years old
St. Vincent’s Needs
• Therapists at St Vincent’s currently measure muscular strength subjectively, or with a hand dynamometer
• St Vincent’s Need: Want a way of measuring the muscular strength and reaction time of pediatric patients quantitatively
Problems with Hand Dynamometer
• Problems– Expensive– Too heavy for the child– Awkward to handle and
squeeze for the child– Not fun
How our Toys meet St Vincent’s Needs
• Fun interactive toy for the children
• Measures their reaction time and muscular strength quantitatively for the therapists– Use the output data to gage the effectiveness
of the physical therapy and to see the progress of each pediatric patient
Quantitative Measurement Toys
• Light up pressing Toy• LVDT value VS. Color
• Whack-a-mole game
Programs we used
• Assembly language to control:- Microcontroller-LCD display-Accelerometer and LVDT (Linearly Variable Displacement Transducer)-Generating sound-Reaction Time Measurement

Reasons for New Design
• Engages muscles for both arms
• Two positions– Arms extended
• Biceps, Brachioradialis, Pectoralis Major, Triceps, Deltoids
– Arms Close to Trunk• Biceps and Deltoids
• Uses LVDT
New light up toy design
Prototype of Light up Pressing Toy
Future Consideration
• Next Semester Projects– Continue working on the light up pressing toy– 2nd edition Whack a mole game with both
reaction time and strength measurement– Punching game for reaction time and strength
measurement

Motivation
• Ventilation systems have many components
• Equipment is difficult to transport to and from the hospital
• Current methods are hazardous to the therapists and the child
• There is a strong need for a better method of equipment transportation
Project Background
•Unorganized equipment
•Suction & O2 tank hanging in back
•Tubing dragging on ground
Project Goals
• Develop a better ventilation transport method for St. Vincent’s by:
– Organizing equipment to remove potential hazards to both child and staff
• Making equipment visible and adjustable
– Consolidating equipment to decrease travel preparation time and difficulty
Larger Equipment
Suction machine in its bag Ventilator
ApneaMonitor
OxygenCanister
Main Equipment
• Ventilator – 11”x14”x4”• Ventilator battery – 4”x6.5”x2.5”• Ventilator back-up battery – 11”x9”x9.5” 28.2 lbs• Suction – 10”x13.5”x7” 9.8 lbs• Oxygen tank – 6.5”x15”x6” 8 lbs• Apnea monitor – 9.5”x7.5”x8” 12 lbs• Apnea monitor battery – 3.5”x5”x3” 2.8 lbs• Tubing
14.8 lbs
Current Design Constraints• Staff must be able to adjust the controls on:
– apnea monitor – ventilator screens
• Staff must be able to easily access:– ambu bag– suction machine
• Must be able to carry in as few trips as possible• Must not be an ergonomic safety hazard• Must fit in Graco extended Duo Glider stroller
Proposed Solution: Container
• Use open container rather than a fabric sack or suitcase to hold equipment– Provides easy access
to equipment– Allows for visibility of
monitors– Equipment stability
and protection
Proposed Solution: Equipment
• Mount ventilator on a steel plate on front of container
• Place backup ventilator battery in the bottom
• Attach Velcro loops on outside to organize tubing
Container Material
• PVC foam – light weight – low cost– moisture resistant– high impact strength
• PVC foam dividers will be molded within the container to further stabilize equipment
Future Work for Next Semester• Test design
– Modify if necessary
• Take container to St. Vincent’s– Therapist approval and
input
• Extend to a home carrier for parents
