Ergonomic Factors

Psychological Factors

Light

• The light from the windows was unfavorable. At midday, the harsh sunlight makes it very difficult for children to work.
• The light from the lights inside of the room was favorable. The inside lights provided the correct amount of light for people to learn and focus. The light was not too bright as well.
• The light created by the laptops of my classmates can be very distracting. It prevents me from focusing on classwork and on the teacher. This is unfavorable.

Sounds

• The 3D printers are constantly active, which distracts students and reduced work completed. This is unfavorable.
• The other students who I sit with socialize(talk) a lot, which prevents me from focusing on what the teacher is saying. This is unfavorable.
• The students at other tables in the class distract the teacher by talking and socializing. This lower work efficiency and creates a situation where progress in class is significantly delayed. All because of student noise and sounds. This is unfavorable.

Textures and Looks

• Softer colors are used in the Fab Lab compared with other classes. This allows for higher levels of focus. This is favorable.
• Smooth black desks in the fab lab are nicer than the desks in other rooms. They are not rough and chipped like the other desks. Students get distracted by the wooden desks. The uniformity and simplicity of the smooth black desks is favorable, as it reduced distractions and increases focus.
• Very cluttered displays create "visual noise". This is very distracting and is unfavorable.

WHM Reassessment - 7/9 or 14/18

Two errors in Texture and Looks

Soft colors - you can see - this is a physiological factor, not psychological

Clutter - you can see

Purpose of the exercise is to distinguish between physiological and psychological ergonomic factors - think the design of an operations console. The chair (comfort or fatigue), longevity in one position, etc. These are design considerations to improve human performance. You are identifying lots of thinks in the Fab Lab that distract learning.....but not ALL factors that distract learning are ergonomic.

WHM Comment

Light is psychological, but vision / visual acuity is physiological - so LED flashing lights are in error

Psychological CAN NOT BE SEEN...but flashing LED lights can be seen

Room Configuration CAN BE SEEN - all physiological

4 right / 5 wrong - 8/18
