1 Selection and description of workplace

1.1 Description of workplaceDescribe the existing workplace though both diagrams, text, pictures (see below) and video. Use the following guidelines for photo making.

Picture position example1. Company plate with WS# and employee names2. Common overview of WP with user

3. Left view work on desk (KB use, chair back support, arms chair support, eye level regarding monitor top)

4. Right view work on desk (KB use, chair back support, arms chair support, eye level regarding monitor top)

5. Leg space under desk without user


6. User sitting on chair

7. Other important picture, e.g. phone use, lighting, hand pain location

Give relevant dimensions.

If you have specification sheets and other technical materials, they belong in the appendix.

1.2 User DescriptionList the types of users who might be using the workplace. Provide a short description of the characteristics for types of the users on your list (e.g., a child is someone with small hands; an engineer is someone with technical knowledge)

1.3 Tasks AnalysisIdentify the primary tasks through which users interact with the workplace/product/system. Observe/interview the users and define the relevant % of working time allocated to them during 1 week/1 month.

Identify the primary tasks through which users interact with the workstation. Choose two computer tasks for an in-depth description. For each task, describe how a user would complete the task using the existing workstation. Descriptions with sufficient detail are those in which the reader can clearly identify the following types of activities:

physical (e.g., press the button), perceptual (e.g., read the signs/labels, hear the warning signs), and cognitive (e.g., decide which button to push, determine what is causing the problem).

2 Checklist for ergonomic evaluation

2.1 Development of checklist and workplace studyPrepare a checklist for ergonomic evaluation of workplace with the following dimensions:

1. Dimension: Work Organization (tasks specification, workload, work monitoring, training)

2. Dimension: Display screens/VDU (monitor, glare)

3. Dimension: Input devices (keyboard, mouse, trackball, telephone headset)

4. Dimension: Furniture (desk, chair, footrest, document holder, wristrest/armrest)

5. Dimension: Work space/ work surface/ layout/ work posture/ seating

6. Dimension: Environment (illumination, temperature, air flow, noise)

7. Dimension: Software

8. Dimension: Health/hazards

9. Dimension: CommonUse the example checklist given on project website (http://www2.sta.uwi.edu/~anikov/optm3041/projects/word-form-2-checklist.docx)

2.2 Workplace study2.2.1. Collect data using the checklist from the workplace2.2.2. Collect data using a lightmeter


http://www2.sta.uwi.edu/~anikov/optm3041/projects/word-form-2-checklist.docx

3 Ergonomic analysis of workplace

3.1 Calculation of workplace hazard risksCalculate using EXCEL sheet the workplace hazard risks for different dimensions using data gathered from assignment 2. Determine the average values for each dimension in % [0,100] transforming the scale x∈[1,5] to y∈[0,100] by formulae y=(x-1)*25. The total health risk is the average risk of all dimensions (1-8). Calculate the dissatisfaction dimension by the formulae dissatisfaction = 100-satisfaction. Present the results in a bar chart (see below example bar chart). Use integer digits and colors as follows: dark green: 0-25%; light green: 26-50%; yellow: 26-75%; red: 76-100%

3.2 Summary of problems and corrective measures Present in a table a summary of problems allocated and the relevant corrective measures (see example table below). Include pictures where appropriate.

Q# Summary of problems allocated Corrective measures to solve


problems allocated12162133

Include pictures Monitor position not directly in front of user; laptop monitor too low; primary monitor too high; head is turned to the side; rotating neck to view monitor places increased demands on neck and shoulders; head not directly over spine; head tilted up/down; head not balanced over shoulders; shoulders: rounded forward, lowered
