 Workplace design and ergonomics

 

Examination of work processes 
in horticulture applying 
three-dimensional motion analysis

In order to maintain the competitiveness of horticultural holdings in the future, the design of work places has to be made more efficient and attractive.

Two CCD-cameras record light pulses of up to a maximum of eight infrared light-emitting diodes, which are connected with and pulsed by a computer. The total pulse frequency lies at 50 Hz. The calculated three-dimensional data appear as ASCII-data and can be interpreted with a special evaluative software.

Colouring of motion lines depending on different speeds / Calculation of known quantities
- length of way      - speed
- duration of time   - area of work
- posture              - number of motions

Division of motion lines into separate motions

The achieved results are definitely superior to mere measurements of time. The known quantities allow evaluations according to economic and ergonomic points of view. A wide use in horticulture as well as in the development of new machines is possible.
