A Comparing Study between People with Reduced Hand Function and Children

This study was conducted in collaboration with Tetra Pak® [1] measuring the hand strength, grip ability, hand size to judge how easy it was to open three packages with a group of 10 people with reduced hand function and 14 children, six years old. The result showed that the hand strength between the group with reduced hand function and the children was quite similar. Also the results from the grip ability test and their judgement of how it was to handle the package was similar. The size of the participants’ hands was the only thing that really differed between the groups. This is an interesting input for designers developing products and packages that should be easy to use for children, but may be even more interesting for developing products where there is a need to exclude children or child protective packages.
