• End Term– Winter 2009

• Faculty Guide– Dr. Beth DeBartolo (ME)

• Primary Customer– National Science Foundation/ Dr. Beth DeBartolo– Nazareth Teaching Clinic-J.J. Mowder-Tinney PT, MS, NCS, CWS

• Secondary Customers– Patients at the Clinic

• Sponsor– National Science Foundation

Overview

• Engaging game• Easy to use game• Not overcomplicate a process that is currently

simple for PT but boring for patient• Provide a method of track patients progress

Risks and Feasibility

• Game won’t keep patients interest• Design won’t be aesthetically appealing• Unfamiliarity with wireless technology• Portability may not be possible• Game development • Material lead times

Customer Needs• Adjustable

– Variable Speeds– Variable Distances

• Safety– Durability

• Ease of use– Physical Therapist

• Portable– Patient

• Cost• Rehabilitation

– Stimulating - Fun– Track patient progress

PROGRAM START

Determine basic connectivity, number of pods, as well as MAC address info of pods.

Check for Pod connectivity

Prompt user to validate discovered Pod count

Display number of Pods discovered, as well as MAC

address information

Pods found No Pods found

“Search for Pods again”Or “Exit Program”

“Pods could not be discovered, or were

discovered incorrectly. Please check power, [etc]...”

Store information about pod locations in an array

Describe the current location (angle, distance) of each Pod

[N, for all Pods]

Pod count incorrect

Pod count correct

Pods should be numbered, with angles show and distances calculated.

Display visual aid of current Pod configuration with “Is this correct?” prompt

Yes, correct No, incorrect

Calculate distances on the fly

Manually edit location of Pods

Name, height, notes, [etc]…

Choose existing patient, or enter new patient information

Manual [pod, target] selection, random location, or implemented games listing

Choose rehabilitation application or game

Configuration corrected.
