Program Background

General Workstations Development Initiative within the Workplace RERC

Program Goal:
The General Workstations Program is conducting research to aid in the development of new designs for workstations in environments where accessible workstations are not available.

Research Questions

  • How do the functional differences between people with and without disabilties effect the application of available inforamtion?
  • Is there an area of overlap in these characteristics that would suggest some optimum position for frequently used system components?

  • Slide 6 of 21

    Research Questions (cont.)

  • What is the impact of design changes on secondary users [customers] at the checkout?
  • In what ways can the benefits of workstation optimization be quantified; ease of use, increased efficiency, increased throughput, decreased fatigue and injury, etc?

  • Slide 7 of 21

    Research Questions (cont.)

    The scope of the research was limited to reach and comfort at this point.

    Working Hypotheses:

  • Workstation height has an impact on participant reach range.
  • Item position has an impact on participant comfort and task completion.

  • Slide 8 of 21

    Mixed Methods Approach


    Slide 9 of 21

    Sample Strategy

    A purposeful sample strategy was developed to include a diverse range of participants with physical characteristics most likely to be limiting given the current checkout configuration.

    Research Methodology

    1. Introduction
    2. Collect anthropometric data
    3. Prepare participant for motion capture
    4. Complete typical grocery checkout tasks on a height adjustable test fixture designed to simulate various workstation configurations
    5. Conduct follow up group interview

    Data Analysis

    Qualitative:
    Content Analysis of group discussion and participant comments

    Quantitative:
    Dartfish: Software package used for motion analysis
    Statistical Analysis: Correlation, Stepwise Regression and Univariate Analysis of Variance

    Slide 14 of 21

    Preliminary Findings

    Qualitative:
    Content Analysis of group discussion

    Slide 15 of 21

    Preliminary Findings

    Qualitative:
    Participant reaction to workstation height was almost perfectly distributed, and highly correlated to descriptive category.

    Graphic: People sitting around a table

    Slide 16 of 21

    Preliminary Findings

    Quantitative:
    Dartfish: Software package used for motion analysis

    Graphic: A bird eye view of a person sitting at his desk with overlaid markers drawn using dartfish software

    Slide 17 of 21

    Preliminary Findings

    Quantitative:
    Dartfish: allowed the monitoring and measurement of the following variables

    Slide 18 of 21

    Preliminary Findings

    Quantitative:
    Preliminary Statistical Analysis was conducted to determine relationships between the variables.

    Slide 19 of 21

    Preliminary Findings

    Quantitative:
