Virtual Environment Auditory Feedback Techniques to aid Manual Material Handling

This paper compares and contrasts three types of auditory feedback techniques to aid safe manual material handling operations. The work reported aims to reduce lower back injuries by allowing people to gauge the forces acting on their lower back whilst moving an object from one location to another. This is particularly useful if the movement is repetitive in nature. Sensors monitor the human user’s head and hand movements in real-time. An analysis of Task Completion Time, Percentage of Harmful Lifts and Response Time to Feedback were analysed and used to identify the appropriateness of each auditory feedback technique.

Questions
Submitted by sceyw3 on Mon, 03/07/2006 - 3:45pm.

Thanks for your contribution in IPROMS 2006. I have a few questions.

What is the intention to test auditory feedback using white-noise, pitch and tempo? Are there any other options?

How can this autidtory feedback techniques be applied into the industry?

Thanks.

various auditory feedback
Submitted by Abdul Aziz on Tue, 04/07/2006 - 7:53am.

Hello
Thanks for the questions. Various type of auditory feedback were tested to differentiate their capability to alert the user of his/her lifting condition in real time while performing virtual lifting task. Auditory feedback was among a good technique to provide feedback to the user without the need to concentrate on vision. This is crucial since the user can focus on other job for visual, while receiving feedback on auditory simultaneously.

Thank you
Dr Faieza Abdul Aziz
