CODY Testing 1


We are testing a Virtual Reality – or VR -- program for using and experiencing home modifications. Virtual Reality is a three-dimensional computer simulation of an environment that you see in a headset. We call this VR program “CODY.”

The purpose of this research is to assess how useful CODY is in assisting and enhancing the ability of adults to experience and choose appropriate home modifications for themselves.


  • You will be asked to participate in VR (virtual reality) testing
  • Research staff will be there to help you with technical equipment, instructions and monitor your safety and comfort
  • Once you have completed testing you will be asked to answer a few surveys about your demographic information and about your perceptions of the usability of and satisfaction with the system and of perceived anxiety.


  • Patients with a mild-to-moderate diagnosis of PD, evaluated using the Unified Parkinson’s Disease Rating Scale (UPDRS) and the Modified Hoehn and Yahr stages I-III, by a fellowship trained neurologist, arriving at the diagnosis by applying strict UK Brain Bank criteria
  • Disease duration is less than 5 years
  • With phone area code of 352; 904
  • Currently on their medications
