There are five aspects of ergonomics: safety, comfort, ease of use, productivity/performance, and aesthetics. Based on these aspects of ergonomics, examples are given of how products or systems could benefit from redesign based on ergonomic principles.
Safety - Medicine bottles: The print on them could be larger so that a sick person who may have bad vision (due to sinuses, etc.) can more easily see the dosages and label. Ergonomics could design the print style, color and size for optimal viewing.
Comfort - Alarm clock display: Some displays are harshly bright, drawing one’s eye to the light when surroundings are dark. Ergonomic principles could re-design this based on contrast principles.
Ease of use - Street Signs: In a strange area, many times it is difficult to spot street signs. This could be addressed with the principles of visual detection in ergonomics.
Productivity/performance - HD TV: The sound on HD TV is much lower than regular TV. So when you switch from HD to regular, the volume increases dramatically. Ergonomics recognizes that this difference in decibel level creates a difference in loudness and hurts human ears and this could be solved by evening out the decibel levels.
Aesthetics - the look and feel of the object, the user experience.
When I did GCSE Resistant Materials, I made a table and on my ergonomics page, I wrote:
My occasional table will need to be comfortable and easy to use, in order to do this I will make sure that…
My table has no sharp edges.
My table has no splinters.
Any compartments are easy to access.
My table is the correct size for the user.
My table has a good finish.
My table has the right shape so it is easy to use in a given location.
I use appropriate materials to enhance comfort.
There is adequate floor space.
My table functions well.
The weight is appropriate (not too heavy.)
My table has easy access for maintenance.
I hope this is of some help to you.
