Although opening jars is problematic for older adults, little is
known about the best interface design for jar lids. PURPOSE OF THE STUDY: To
evaluate preferences in current and new lids for persons self-reporting
difficulty with opening jars. METHODS: Participants were twenty-six older females
with hand pain. Preference ratings were obtained for twenty-four current and
forty-two new lid designs of different sizes, shapes, and textures. RESULTS:
Current lids with taller heights, larger diameters, and textured sides were
preferred. Texture compensated for limitations of shorter and smaller diameter
lids. Preferred characteristics in new smaller diameter lids included taller
height, non-circular top shapes, and concave side shapes. Taller height,
regardless of shape, was preferred for new medium diameter lids. Least preferred
for small and medium lids was the short height, traditional circular shape.
CONCLUSIONS: The preferences of jar lids made by elderly females with hand pain
support the recommendations commonly suggested by clinicians to increase the
height, diameter, texture, and shape of jars, especially for lids smaller than 40
mm.
