• Independence for individuals with disabilities

Individuals face dangers in their everyday lives

Lack of knowledge or ability

Safety skills in many settings

• Technological devices can help afford independence Pagers, virtual reality, hand held computer devices, and

cellular phones » (Padgett, Stickland, & Coles, 2006; Riffel, Wehmeyer, Turnbull, Lattimore, Stock, & Fisher

2005; Self, Scudder, Weheba, & Crumrine, 2007; Taylor, Hughes, Richard, Hoch & Coelo, 2004).

Introduction


Introduction

• Independence can be afforded to these individuals across settings. In the home (Cheslock, Barton-Hulsey, Romski, &Sevcik, 2008; Hersh

&Treadgold, 1994; Lancioni, Singh, O’Reilly, Sigafoos, Campodonico, & Oliva, 2008).

In the workplace (Davies, Stock, & Wehmeyer, 2001; Davies, Stock, & Wehmeyer, 2002a).

In the community (Taylor, Hughes, Richard, Hoch & Coello, 2004; Zaruba, Kamangar, & Huber; 2003).

• Training individuals with disabilities to use public transportation is one of the least researched areas (Rosenkvist, Risser, Iwasson, Wendel, and Stahl 2009)


• Fischer and Sullivan (2002):

Focused on understanding the barriers experienced by people with cognitive disabilities, designing a user friendly model to reduce the cognitive load for individuals with cognitive disabilities within public transportation

• Sohlberg, Todis, Fickas, Hung, and Lemoncello (2005):

Examined navigational patterns, focus groups

• Sohlberg, Fickas, Hung, and Fortier (2007):

Developed and tested the effectiveness of using a PDA to deliver four different prompting methods and to see which prompting method was most effective Focused on manually-triggered alerts for pedestrians

Audio was most successful and most preferred by users

Introduction


Travel Assistance Device (TAD)

TAD is a transit navigation “app” for cell phones

Caretakers or travel trainers can plan trips via website:

(1) Home to Work(2) Work to Home(3) Home to Movie

Work to HomeWork to Home

Distance to Final Stop:5.6 miles

18 Livingston West

TADTAD

OK

Pull the Cord Now!

(+Sound and Vibration)


TAD cell phone app tells the traveler to “Get Ready” and “Pull the Cord Now!” when it is time for them to exit the bus.

Prompts are visual, auditory, and tactile.


Behavior Analysis Study

• Purpose:

To determine whether the prompts given by the TAD would exhibit stimulus control over participants’ behavior of pulling the “stop” cord to:

1. Stop the bus at the appropriate time

2. Exit the bus at the appropriate stop.


Method

ParticipantsInclusion criteria: ambulatory & travel trained.3 individuals with moderate mental retardation.

“Mark”, “Paige”, “Carl”

SettingTAD training was done in a class room setting using

Behavioral Skills Training (BST).Baseline and post training tests were carried out on a city

bus at Hillsborough Area Regional Transit (HART) in Tampa, Florida.

Target Behaviors1. The participant must pull the bus cord signaling the

appropriate stop

2. The participant must exit the bus at the appropriate stop.


Method

Data CollectionTrials:

Each trial began at a local transit center.

Once the participant and inconspicuous observer board the bus the trial began.

Once the participant exited the bus the trial was considered complete.

Participant Directions:Participants were told to take “X” bus to “Y” location.

Baseline: No prompts or feedback were given.

Post Training: Prompts were given by the TAD.


Method

• Participant Safety:

The inconspicuous observer entered the bus after the participant.

If the participant failed to pull the cord at the appropriate location the inconspicuous observer pulled the cord.

A familiar research assistant was waiting for the participant to exit the bus at the appropriate bus stop.

The primary researcher followed the bus during all trips.


Method

Mobile Device: Sanyo 7050 phone on Sprint


mobile application

Research Design:Data was evaluated in an ABAB reversal design

Interobserver Agreement (IOA)Assessed for 33% of all trials.

Baseline 1= 83%,

Post training 1, Baseline 2, & Post training 2 = 100%

Overall IOA was 95.8%


ProcedureBaseline:

Participants completed novel trips at different transit centers

TAD:Training to use TAD was done using Behavior Skills

Training style training (Himle, Miltenberger, Flessner, & Gatheridge, 2004).

Post Training:TAD was activated and trips selected for the

participants

In-Situ Training: In-Situ training would have taken place after 3

consecutive incorrect trials. Never needed to be implemented during study

Method


Results – Participant “Mark”


Results – Participant “Paige”


Results – Participant “Carl”


Results & Discussion

• Results provide supporting evidence that the TAD is an effective tool to prompt individuals to exit the bus at a desired location.

• When no prompts were given, all subjects failed to pull the stop request cord and exit the bus at the correct location

• When TAD was used, the subjects pulled the stop request cord and exited the bus at the correct location

• One rider asked the bus driver for help Driver gave the rider incorrect directions

Rider exited the bus at the wrong stop


Results & Discussion

• Limitations

Generalization – small population in this study

• Future research

Other, and larger, populations Individuals with visual, physical impairments, elderly

Longer trips Multi-link trips with transfer present additional challenges

Training needed Full user experience of application (e.g., User starting

application, selecting options on phone, etc.)

How to “train the trainer”?
