- W777744450 abstract "The design of hand interfaces should use the ergonomic knowledge related to biomechanical forces involved in manipulation by individuals with different characteristics, including age and genders groups. Among the most common interfaces in the daily living are packagings, which are essential to conservation, transportation and sales of most products on the market. Deficiencies in the design of these packagings can lead users to have difficulties in opening, and this applies to many packagings with screw caps, which represent a constraint to users, especially to users with smaller biomechanics capacity, such as women or the elderly. In Brazil, this type of packaging are used for non-alcoholic soft drinks, or just soft drinks, which are widely consumed by individuals of various ages and both genders. This study aimed to evaluate and analyze the influence of design in the application of manual forces during the opening simulation of soft drinks plastic packagings. Hence, a biomechanical assessment was conducted (torque prehension), in simulated activities with 180 Brazilian adults of different genders and age groups, using five plastic bottles of different formats. Additionally, we collected the user’s perception of difficulty for each packaging analyzed. The results indicate that the adult age group (30-55 years old) has greater capacity for opening in relation to others (18-29 years, refereed as young; and over 55 years, elderly). Also could be noted significant differences between genders and between dominant and non-dominant hand in all situations. Moreover, the biomechanical capabilities of these groups were compared to the real need for application of forces to open the packaging, allowing to estimate that a large proportion of the population that has to make great efforts to open this type of packaging." @default.
