Margin of error


Mathilde Hellard

In the production of objects, error is often related to manufacturing defects. Products are considered abnormal and unusable. We can also be confronted to errors of comprehension of the objects in their functions, their uses or their ergonomics. In that case, users are led to bear the margin of error.

In my project, I worked on a careful observation of users in their everyday life through the prism of a strong use constraint: using only one hand. I focused on 3 known contexts: opening a jar, preparing a toothbrush and emptying the trash. With only one hand, these mundane actions take a more complicated turn.

This allowed me to build adapted strategies to answer these difficulties of use.
