Abstract

IntroductionAlthough opening jars is problematic for older adults, little is known about the best interface design for jar lids.Purpose of the studyTo evaluate preferences in current and new lids for persons self-reporting difficulty with opening jars.MethodsParticipants 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.ResultsCurrent 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.ConclusionsThe 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.
