Augmentative Assistive Communication (AAC) Project Criteria: 

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: 

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 – 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: 

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: 

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: 

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: 

Users Each user will have: Login Password E-mail Preferences Girl or Boy voice Pictures per page Other Information

Entries: 

Entries Each title entry is related to specific data Image Sound Title

Structure: 

Structure 1 Food 2 School 3 Snacks 4 Fruit 5 Book bag 6 Colors 7 Pudding 8 Yogurt 9 Banana 10 Grape 11 Ruler 12 Crayons 13 Red 14 Yellow Recursive Storage System

Slide16: 

Sample Dynamic Page Status After receiving input from Amy we have begun to code how the dynamic page will interact with the databases Dynamically generated pages completed Unique user preferences determine page layout Load images based off of recursive structure database Clicking images links to the next page and plays sound Dynamic Site Demo

Slide17: 

Peach Strawberries Grapes Pineapple With Toolbars

Goals for Next Semester: 

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: 

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: 

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

Slide22: 

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: 

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: 

Quantitative Measurement Toys Light up pressing Toy LVDT value VS. Color Whack-a-mole game

Programs we used: 

Programs we used Assembly language to control: - Microcontroller -LCD display -Accelerometer and LVDT (Linearly Variable Displacement Transducer) -Generating sound -Reaction Time Measurement

Motivation: 

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: 

Project Background Unorganized equipment Suction & O2 tank hanging in back Tubing dragging on ground

Project Goals: 

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: 

Larger Equipment Suction machine in its bag Ventilator Apnea Monitor Oxygen Canister

Main Equipment: 

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: 

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: 

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: 

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: 

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: 

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
