Time Up and Go Test (TUG test): Kinect-based Fall Risk Evaluation and Feedback System

Time Frame:

Fall 2016

Method:

  • Interviews
  • Observation
  • Pilot test
  • SUS
 
Client:
Dr. Phillips Lorraine and Mizzou engineering students

Client URL:
None

Goal:
  • Identify the usability of TUG test.
  • Offer refinement of the Kinect-based fall risk evaluation and feedback system.
Process:
The TUG test is a Kinect-based fall risk and evaluation feedback system for elderly users developed by Dr. Phillips Lorraine and Mizzou engineering students. The TUG test times an individual to rise from sitting in a standard armchair, walk 3 meters, turn, return to the chair, and sit down. It is a measure of functional balance and a sensitive and specific measure of fall risk in community-dwelling balance-impaired older adults. The test used Kinect depth cameras to compute gait parameters.

In Fall 2016, the IE Lab was hired to conduct usability testing and offer refinement of the Kinect-based fall risk evaluation and feedback system. In this project, the tools and methods we applied for the evaluation of the TUG test include the pilot test, instruction slides, interview guide and System Usability Score survey (SUS), observation note table, and Morae recorder software.

Findings:
The TUG test system still needs improvement in three aspects: instruction slides, walking test, and the result sheets. Some main recommendations to the TUG test system are that the duration of the instruction slides should be optimized, the walking test should give participants clear signals and indicators as for when to start and when to stop, and the interpretation text should be placed at a more obvious location on the result sheet.
